Parts of Speech

Chapter Overview

Language is not a random collection of words thrown together in hope. Every word in every sentence occupies a position, performs a function, and relates to the words around it in a specific, describable way. The system that describes these functions is called grammar, and the foundation of that system — the first thing any serious student of English must understand — is the parts of speech.

A part of speech is a category that tells you what grammatical job a word performs in a sentence. Not what the word means in isolation. Not how long it is or how it sounds. But what role it plays in the construction of meaning when it sits among other words in a sentence.

English recognises eight parts of speech:

Noun · Pronoun · Adjective · Verb · Adverb · Preposition · Conjunction · Interjection

Every word in English belongs to at least one of these categories. Some words belong to more than one, depending on how they are used. Run is a verb in “She runs every morning” and a noun in “She went for a run.” Fast is an adjective in “She is a fast runner” and an adverb in “She runs fast.” The word doesn’t change — the grammatical role does. And the part of speech follows the role, not the word.

This chapter covers all eight parts of speech in full — their definitions, their subcategories, their functions within sentences, the rules that govern their use, and the common errors that arise when those rules are misunderstood or ignored.

PART ONE: THE NAMING WORDS

Chapter 1 — Noun

1.1 Definition

A noun is a word that names something. It can name a person, a place, a thing, a quality, a concept, or an idea. It is the most fundamental part of speech — the naming unit of language. Before anything can be said about anything, that thing must first be named.

The teacher stood at the front of the classroom. She spoke about courage and patience for an hour. Dhaka is one of the most densely populated cities in the world.

Everything in bold is a noun. Some refer to physical things that can be pointed at — classroom, cities. Some refer to people — teacher. Some name a specific place — Dhaka. Some name qualities that exist only as abstract concepts — courage, patience. All of them are nouns.

Nouns answer the question: What is being named?

1.2 Types of Nouns

1.2.1 Proper Noun

A proper noun names a specific, unique person, place, organisation, or thing. It distinguishes one particular individual from all others of the same type. Proper nouns always begin with a capital letter, regardless of where they appear in a sentence.

People: Rahim Uddin, Dr. Fatima Hassan, Professor Ahmed, Shakespeare

Places: Dhaka, Bangladesh, the Himalayas, the Padma River, Green Road

Organisations: Dhaka University, the United Nations, Amnesty International

Days, months, festivals: Monday, January, Eid al-Fitr, Pohela Boishakh, Christmas

Examples in sentences:

• Rahim moved to Dhaka after finishing his degree at Dhaka University.
• The Padma flooded three districts in August.
• Professor Ahmed received the award on Monday.

Key rule: When a proper noun is used as a common descriptor, it loses its capital. “I need a shakespeare in this office” (meaning a brilliant writer) — lowercase, because it is being used as a type, not a name.

1.2.2 Common Noun

A common noun names a general category rather than a specific individual. It refers to any member of a class of things, not one particular named thing. Common nouns do not begin with a capital letter unless they open a sentence.

teacher, city, river, book, school, dog, chair, idea, country

Examples in sentences:

• The teacher stood at the front of the room.
• She lives near a river in a small city.
• He borrowed a book from the library.

Proper vs. Common — side by side:

The distinction is one of specificity. A common noun names a type. A proper noun names the specific, irreplaceable individual within that type.

1.2.3 Concrete Noun

A concrete noun names something that can be experienced through the five physical senses — something that can be seen, touched, heard, smelled, or tasted. If you can perceive it physically, it is concrete.

Seen: table, mountain, sky, book, face, building
Touched: fabric, stone, water, wood, skin
Heard: music, thunder, voice, noise, bell
Smelled: smoke, bread, rain, perfume, petrol
Tasted: salt, sugar, lemon, coffee, rice

Examples in sentences:

• The rain soaked through his jacket on the way home.
• She could smell the bread baking from the next room.
• He put the book on the table and sat down.

Important: Many nouns are concrete in some uses and abstract in others. “Light” is concrete when it refers to the physical phenomenon — “The light was blinding.” It is more abstract when used figuratively — “She brought light into everyone’s life.”

1.2.4 Abstract Noun

An abstract noun names something that cannot be perceived through the physical senses — a concept, quality, emotion, state, or idea that exists only in the mind or in human experience. You cannot point at abstract nouns, photograph them, or hold them.

Emotions: love, anger, fear, joy, guilt, loneliness, pride
Qualities and virtues: courage, honesty, patience, kindness, wisdom, loyalty
Concepts and ideas: freedom, justice, democracy, truth, time, knowledge
States and conditions: health, poverty, success, failure, peace, chaos

Examples in sentences:

• She showed extraordinary courage throughout the ordeal.
• Justice was finally served after a long and painful wait.
• He carried a deep sense of guilt about what had happened.
• Freedom means different things to different people.

Forming abstract nouns from other words:

Common error: Using articles incorrectly with abstract nouns. Abstract nouns used in a general sense take no article: “Patience is a virtue” — not “The patience is a virtue.” But when referring to a specific instance, the is correct: “The patience she showed that day was remarkable.”

1.2.5 Countable Noun

A countable noun (also called a count noun) names something that can be counted as individual, discrete units. Countable nouns have both a singular and a plural form.

Singular → Plural patterns:

With articles and numbers:

• She borrowed a book from the library. / She borrowed three books.
• An apple a day keeps the doctor away. / She bought five apples.

Questions with countable nouns use how many:

• How many students are in the class?
• How many mistakes did he make?

1.2.6 Uncountable Noun (Mass Noun)

An uncountable noun names something that cannot be counted as individual discrete units — substances, liquids, abstract qualities, and collective categories. These nouns have no plural form and cannot be preceded by a or an.

Liquids and substances: water, milk, oil, coffee, sand, air, blood, gold
Foods in general: rice, bread, sugar, flour, meat, butter, cheese
Abstract qualities: advice, information, knowledge, courage, patience, honesty
Categories: furniture, equipment, luggage, clothing, homework, traffic
Academic disciplines: mathematics, music, physics, literature, philosophy

With uncountable nouns, use: some, much, a little, a great deal of, a piece of, a bit of

Examples:

• She gave me some very good advice about the situation.
• There is a little milk left in the fridge — not much.
• He bought a new piece of furniture for the living room.

Questions with uncountable nouns use how much:

• How much water do you drink per day?
• How much information do we actually need?

Common error — making uncountable nouns plural:

• ✗ She gave me some advices.
• ✓ She gave me some advice.
• ✗ I have three homeworks to finish tonight.
• ✓ I have a lot of homework to finish tonight.

Note: Some nouns can be both countable and uncountable depending on meaning. “Would you like some coffee?” (uncountable — the substance) vs. “We ordered two coffees.” (countable — two cups of coffee). Context determines which applies.

1.2.7 Collective Noun

A collective noun is a single word that names a group of people, animals, or things considered together as one unit. The word is grammatically singular even though it refers to multiple members.

Groups of people: team, family, crew, committee, jury, staff, audience, class, crowd, government
Groups of animals: flock (birds), herd (cattle), pack (wolves), pride (lions), swarm (bees), school (fish)
Groups of things: bunch (keys/flowers), set (tools), fleet (ships), collection (stamps)

Examples in sentences:

• The team won the championship after months of preparation.
• The jury reached its verdict after three days of deliberation.
• A flock of birds flew in formation across the grey sky.
• The committee has approved the proposal unanimously.

British vs. American English — singular or plural verb?

• British English tends to treat collective nouns as plural: “The team are playing well this season.”
• American English tends to treat them as singular: “The team is playing well this season.”

1.2.8 Compound Noun

A compound noun is formed by joining two or more words together to create a new noun with a new, unified meaning — one that is often distinct from the meanings of the individual parts.

Written as one word (closed compound): toothbrush, sunlight, bookshelf, football, bedroom, newspaper, rainfall, haircut, notebook, classroom
Written with a hyphen (hyphenated compound): mother-in-law, well-being, self-confidence, long-term, up-to-date, twenty-one, editor-in-chief
Written as two words (open compound): bus stop, post office, swimming pool, full moon, high school, ice cream, living room, first aid

Examples in sentences:

• She left her toothbrush at the bus stop by mistake.
• His mother-in-law arrived just as the swimming pool was being cleaned.
• The notebook on the bookshelf belongs to her.

Key observation: Many compound nouns evolve over time — moving from open to hyphenated to closed as they become more established in the language. Email was once e-mail, and website was once web site. This is an ongoing process and both forms are often acceptable during transition periods.

1.2.9 Possessive Noun

A possessive noun shows ownership, association, or relationship. It is formed by adding an apostrophe and s to a noun.

Singular nouns — add ‘s:

• Rahim’s application was the strongest submitted.
• The teacher’s explanation made everything clear.
• My mother’s cooking is unlike anything else.

Plural nouns ending in s — add apostrophe only:

• The students’ essays were collected before noon.
• The teachers’ meeting runs every second Thursday.
• The players’ performance improved steadily.

Irregular plurals (not ending in s) — add ‘s:

• The children’s playground was newly renovated.
• The women’s team won the regional championship.
• The men’s changing room is on the left.

Names ending in s — both forms acceptable: James’s report or James’ report — both correct. Consistency within a document matters more than which you choose.

What possessive nouns express:

1.2.10 Verbal Noun (Gerund)

A gerund is a verb form ending in -ing that functions as a noun. It looks like a verb, but it performs the grammatical role of a noun — acting as the subject, object, or complement of a sentence.

As subject:

• Swimming is great exercise for the whole body.
• Overthinking is exhausting and ultimately counterproductive.
• Reading daily sharpens your thinking in subtle ways.

As object of a verb:

• She enjoys reading late at night.
• He avoided answering the difficult questions.
• They considered leaving before the situation worsened.

As object of a preposition:

• She is good at explaining complex topics.
• He left without saying goodbye to anyone.
• They succeeded in finishing the project on time.

Gerund vs. Present Participle: Both end in -ing, but serve different roles. A gerund is a noun — “Swimming is good exercise.” A present participle is part of a verb phrase — “She is swimming in the pool.” The form is identical; the function determines the category.

1.3 Functions of Nouns in a Sentence

PART TWO: THE REPLACING WORDS

Chapter 2 — Pronoun

2.1 Definition

A pronoun is a word that replaces a noun — or a noun phrase — so that it does not have to be repeated. The noun that a pronoun replaces is called its antecedent. The pronoun must agree with its antecedent in number, gender, and person.

Rahim went to the market because he needed vegetables for his dinner.

Without pronouns, the sentence would read: “Rahim went to the market because Rahim needed vegetables for Rahim’s dinner.” Clumsy, repetitive, and unnatural. The pronouns he and his resolve all of that in two small words.

Pronouns answer the question: What replaces the noun?

2.2 Types of Pronouns

2.2.1 Personal Pronoun

Personal pronouns refer to specific people or things based on grammatical person (first, second, or third), number (singular or plural), and gender (masculine, feminine, or neuter). Crucially, personal pronouns change form based on their grammatical role in the sentence — this change is called case.

Examples — subjective (subject position):

• I stayed behind to help with the arrangements.
• She runs the entire department on her own.
• They submitted the report three days early.

Examples — objective (object position):

• She called him early in the morning.
• He helped her move the heavy boxes.
• The teacher praised them for the quality of their work.

Common error — compound subjects and objects:
✗ Her and I went to the market. → ✓ She and I went.
✗ She invited my brother and I. → ✓ She invited my brother and me.
Test: Remove the other person. Would you say “Her went”? No — “She went.” Would you say “She invited I”? No — “She invited me.”

2.2.2 Possessive Pronoun

Possessive pronouns show ownership and stand completely alone — they do not need a noun after them. This distinguishes them from possessive adjectives (my, your, his, her, its, our, their), which must precede a noun.

Critical rule: Possessive pronouns NEVER take an apostrophe. “The mistake was her’s” is always wrong. “The mistake was hers” is always right. This applies to all possessive pronouns without exception.

2.2.3 Reflexive Pronoun

Reflexive pronouns are formed by adding -self (singular) or -selves (plural) to the possessive or objective form of personal pronouns. They serve two distinct functions:

Function 1 — Reflexive use (action bounces back to subject):

• She cooked the entire meal herself.
• He hurt himself during the morning practice session.
• We painted the room ourselves over the weekend.
• The door seemed to close itself.

Function 2 — Intensive use (emphasis only — removable without changing core meaning):

• The director herself reviewed every single application.
• I myself have made that exact same mistake before.
• The president himself attended the opening ceremony.

The test: Remove the reflexive pronoun. If the sentence breaks grammatically, it is reflexive. If it survives but loses emphasis, it is intensive.

• She hurt herself. → “She hurt” doesn’t work → Reflexive
• The director herself reviewed it. → “The director reviewed it” works → Intensive

Error to avoid: Myself is not a polite substitute for me. “Please contact myself if you have questions” is incorrect. “Please contact me“ is the right form.

2.2.4 Demonstrative Pronoun

Demonstrative pronouns point directly at something — indicating whether it is near or far, and whether it is singular or plural.

Examples:

• This is the best option we currently have available.
• That was completely unexpected by everyone in the room.
• These are the freshest mangoes in the entire market.
• Those belong to the other team — not to us.

Demonstrative pronoun vs. demonstrative adjective:

• This is mine. → pronoun (stands alone — no noun follows)
• This book is mine. → adjective (modifies the noun book)

2.2.5 Interrogative Pronoun

Interrogative pronouns are used to ask questions. They replace the unknown piece of information being sought.

Who vs. Whom:

• Who is the subjective form — used when the person is the subject.
• Whom is the objective form — used when the person is the object.
• Test: Substitute he/she or him/her.
  • Who called? → He called → Who ✓
  • Whom did she call? → She called him → Whom ✓

2.2.6 Relative Pronoun

Relative pronouns introduce relative clauses — subordinate clauses that provide additional information about a noun that has already been mentioned. They simultaneously replace a noun and connect the clause to the rest of the sentence.

Defining vs. Non-defining relative clauses:

A defining (restrictive) clause identifies which specific person or thing is meant. It is essential to the meaning and takes no commas.

• The student who scored highest received the award. (tells us which student)

A non-defining (non-restrictive) clause adds extra information about something already identified. It is not essential and is set off by commas.

• Professor Ahmed, who has been teaching for thirty years, received the award.

Note: That can only be used in defining clauses, never non-defining ones. Which can be used in both, though it is preferred in non-defining clauses.

2.2.7 Indefinite Pronoun

Indefinite pronouns refer to people or things without specifying exactly who or what. They are intentionally general or vague.

Singular indefinite pronouns (always take singular verb):

• someone, anyone, everyone, no one, nobody, somebody, anybody, everybody
• something, anything, everything, nothing
• each, either, neither, another, one, other

Plural indefinite pronouns (always take plural verb):

• both, few, many, others, several

Indefinite pronouns that can be singular or plural (determined by context):

• all, any, more, most, none, some, such

Examples:

• Someone left their umbrella by the door. (singular)
• Everyone has finished their assignment. (singular — despite the collective sense)
• Many have tried; few have succeeded. (both plural)
• None of the answers was acceptable. (singular — treating as “not one”)
• None of the students were present. (plural — treating as “not any”)

Agreement trap: Everyone, anyone, someone, and nobody are grammatically singular and take singular verbs — even though they feel collective. “Everyone is here” — not “Everyone are here.”

2.2.8 Reciprocal Pronoun

Reciprocal pronouns express a mutual action or relationship — the action goes in both directions simultaneously between two or more parties.

There are exactly two reciprocal pronouns in English:

• each other — traditionally used for two people
• one another — traditionally used for three or more

Examples:

• The two friends hadn’t seen each other in over three years.
• The teammates encouraged one another throughout the difficult match.
• They looked at each other and simultaneously started laughing.
• Members of the team supported one another through every setback.

Note: In contemporary English, the distinction between each other and one another is loosening. Many speakers and writers use them interchangeably, and most style guides now accept both in either context.

2.2.9 Intensive Pronoun

Intensive pronouns use the same forms as reflexive pronouns (myself, yourself, himself, herself, itself, ourselves, yourselves, themselves) but serve purely to add emphasis to a noun or pronoun. They are always removable — removing them does not break the sentence, but it removes the emphasis.

• The director herself reviewed every single application. → emphasis on who did the reviewing
• I myself have made that exact same mistake before. → personal acknowledgment
• He built the entire fence himself without any assistance.
• The king himself opened the ceremony in front of thousands.

2.2.10 Distributive Pronoun

Distributive pronouns refer to members of a group individually and separately — they distribute the reference across each member one at a time, rather than addressing the group collectively.

Forms: each, either, neither, any, none

• Each of the students submitted a completely different topic.
• Either of the two roads will take you to the town centre.
• Neither of the candidates fully impressed the selection panel.
• None of the applicants met the minimum experience requirement.
• Any of these three options will work perfectly well.

Grammar rule: Distributive pronouns almost always take a singular verb, because the focus is on each individual member of the group, not on the group collectively.
Each of the students has submitted their work. ✓ (not have)
Either of the answers is acceptable. ✓ (not are)

PART THREE: THE DESCRIBING WORDS

Chapter 3 — Adjective

3.1 Definition

An adjective is a word that describes, modifies, or qualifies a noun or pronoun. It adds information about the noun — telling us what kind it is, which one, how many, or how much — and in doing so, narrows the noun from a broad general category to something more specific and vivid.

She wore a long, crimson dress to the formal dinner. He is a dedicated and thoughtful teacher. Three students submitted late assignments.

Without adjectives, “She wore a dress” could describe any dress in existence. “A long, crimson dress” eliminates virtually every other possibility. That narrowing power is the essential function of adjectives.

Adjectives answer the questions: What kind? Which one? How many? How much?

3.2 Types of Adjectives

3.2.1 Descriptive Adjective (Qualitative Adjective)

Descriptive adjectives describe a quality, characteristic, or attribute of a noun — colour, size, shape, texture, personality, appearance, and so on. This is the largest and most varied category of adjectives.

Colour: red, blue, golden, pale, crimson, translucent
Size: large, tiny, enormous, compact, vast, minuscule
Shape: round, square, oval, angular, cylindrical
Texture: smooth, rough, silky, coarse, velvety
Age: old, ancient, modern, new, young, elderly
Personality: kind, harsh, brilliant, arrogant, gentle
Condition: broken, fresh, rotten, clean, damaged

Examples in sentences:

• She wore a warm, elegant coat against the bitter wind.
• He has a sharp mind and a warm personality.
• The old, crumbling walls of the ancient fort stood in silent dignity.

Order of adjectives: When multiple descriptive adjectives precede a noun, English follows a specific conventional order. Violating this order sounds unnatural, even if speakers cannot always articulate why.

Opinion → Size → Age → Shape → Colour → Origin → Material → Purpose + Noun

• a lovely little old rectangular green French silver whittling knife

In practice, rarely more than two or three adjectives precede a noun:

• a beautiful old building ✓ — not “an old beautiful building”
• a long black coat ✓ — not “a black long coat”

3.2.2 Adjective of Number (Numeral Adjective)

These adjectives tell you how many or in what order. They are divided into three subcategories:

Definite numeral adjectives — exact numbers: one, two, three, ten, a hundred, a thousand
Three letters arrived this morning.

Ordinal adjectives — position or sequence: first, second, third, fourth, last, next, previous
She was the first person to arrive and the last to leave.

Indefinite numeral adjectives — approximate or unspecified quantity (as adjectives before nouns): many, few, several, all, some, any, both, enough
Several complaints were filed. / All members must attend.

3.2.3 Adjective of Quantity (Quantitative Adjective)

Adjectives of quantity describe how much of something — not a countable number, but an amount or degree. They are used specifically with uncountable nouns.

• some, much, little, enough, sufficient, more, less, no, whole, half, great

Examples:

• She drank enough water throughout the long day.
• There is very little time left before the submission deadline.
• He has sufficient experience for this particular role.
• Pour some milk into the bowl and stir.

Quantity vs. Number distinction:

• How many books? → Number (countable)
• How much water? → Quantity (uncountable)
• Few students (number — small countable group)
• Little water (quantity — small uncountable amount)

3.2.4 Demonstrative Adjective

Demonstrative adjectives use the same four words as demonstrative pronouns — this, that, these, those — but instead of standing alone, they appear directly before a noun and modify it.

Examples:

• This phone needs to be charged immediately.
• That building was constructed more than a century ago.
• These mangoes are the sweetest ones I have tasted.
• Those students finished their work before anyone else.

The critical distinction:

• This is mine. → demonstrative pronoun (stands alone)
• This phone is mine. → demonstrative adjective (modifies phone)

3.2.5 Possessive Adjective

Possessive adjectives show that a noun belongs to or is associated with someone. They always appear before a noun — this is what distinguishes them from possessive pronouns, which stand alone.

Examples:

• My laptop needs charging.
• Have you finished your assignment?
• Her presentation was the strongest one submitted.
• The company updated its privacy policy.
• Their flight was cancelled due to heavy fog.

Critical warning — its vs it’s:
Its = possessive adjective: The cat licked its paw.
It’s = contraction of it is or it has: It’s raining outside.

3.2.6 Interrogative Adjective

Interrogative adjectives are question words that modify a noun directly — they ask a question about the specific noun they precede.

Forms: what, which, whose

Examples:

• What colour do you prefer — blue or green?
• Which route should we take to avoid the traffic?
• Whose bag is blocking the doorway?
• What size shoes does he wear?
• Which candidate impressed you the most?

Interrogative adjective vs. interrogative pronoun:

• Which do you prefer? → pronoun (stands alone — no noun follows)
• Which colour do you prefer? → adjective (modifies colour)

3.2.7 Distributive Adjective

Distributive adjectives refer to each member of a group individually, one at a time — not all together as a collective unit.

Forms: each, every, either, neither, any, both

Examples:

• Each student received a personalised certificate.
• Every seat in the entire hall was taken.
• Either answer would be considered acceptable.
• Neither candidate fully met all the stated criteria.
• Any member of the team can raise a concern.
• Both doors were left open through the night.

Grammar rule: Distributive adjectives take a singular noun and a singular verb (except both, which takes plural).
Each student has submitted their work. ✓
Every answer was checked twice. ✓
Both students have submitted. ✓ (both = plural)

3.3 Degrees of Comparison

One of the most important features of adjectives is their ability to express degrees — they can indicate not just a quality, but how much of that quality exists compared to something else. English has three degrees:

3.3.1 Positive Degree

The base form — describes a quality without making any comparison. Simply states that the quality exists.

• She is a tall woman.
• He is a dedicated teacher.
• It was a cold morning.

3.3.2 Comparative Degree

Used when comparing two things — one has more of a quality than the other.

Formation rules:

• One-syllable adjectives → add -er: tall → taller, cold → colder, fast → faster
• Two-syllable adjectives ending in -y → change y to i and add -er: happy → happier, early → earlier
• Longer adjectives (most two-syllable and all three-syllable+) → use more: more beautiful, more dangerous, more dedicated

Examples:

• She is taller than her older brother.
• This road is more dangerous than the other one.
• Today feels colder than yesterday.

3.3.3 Superlative Degree

Used when comparing three or more things — identifying the one that has the most or least of a quality.

Formation rules:

• One-syllable adjectives → add -est: tall → tallest, cold → coldest
• Two-syllable adjectives ending in -y → iest: happy → happiest
• Longer adjectives → use most: most beautiful, most dangerous

Superlatives almost always take the in front of them.

Examples:

• She is the tallest player on the entire team.
• That was the most difficult question on the entire paper.
• He is the best candidate we have interviewed.

Irregular forms:

PART FOUR: THE ACTION AND STATE WORDS

Chapter 4 — Verb

4.1 Definition

A verb is a word that expresses an action, occurrence, or state of being. It is the engine of the sentence — the indispensable element without which a sentence cannot exist. A group of words without a verb is a fragment, not a sentence. Everything else in a sentence — subject, object, modifiers — orbits around the verb.

She writes every morning before going to work. The meeting has been cancelled without explanation. He seems distracted and unsettled today. They should have arrived more than an hour ago.

Verbs answer the question: What happens? What is the state?

4.2 Types of Verbs

4.2.1 Action Verb

Action verbs describe something the subject actively does — either physically or mentally. They are the most intuitive type of verb.

Physical action verbs: run, build, write, kick, carry, eat, throw, wash, climb, push
Mental action verbs: think, believe, consider, remember, imagine, decide, wonder, forget

Examples:

• She ran the entire five kilometres without stopping.
• He kicked the ball clean over the crossbar.
• She considered every available option before making a decision.
• He remembered the address after a long, tense pause.

Note: Mental action verbs can overlap with stative verbs. “She is thinking about it” (action — active mental process) vs. “She thinks it’s wrong” (stative — mental position or opinion). Context and meaning determine the category.

4.2.2 Stative Verb

Stative verbs describe a state rather than an action — a condition, relationship, feeling, perception, or mental position that simply exists rather than actively occurs.

Emotions and feelings: love, hate, fear, like, dislike, prefer, enjoy, mind
Mental states and beliefs: know, believe, think (=opinion), understand, doubt, remember, forget, recognise
Perception: see, hear, smell, taste, feel, seem, appear, look
Possession and existence: have, own, possess, belong, contain, include, lack

The defining rule of stative verbs: They are not normally used in continuous tenses. You cannot be “in the process” of knowing something — you either know it or you don’t.

• ✗ I am knowing the answer.
• ✓ I know the answer.
• ✗ She is loving that song right now.
• ✓ She loves that song.

Exception: Some stative verbs can be used in continuous form when the meaning shifts to describe an active, ongoing experience rather than a permanent state.

• I am loving this new restaurant. (informal — experiencing pleasure right now)
• He is thinking about the problem. (active mental process — not just holding a belief)

4.2.3 Transitive Verb

A transitive verb requires a direct object — a noun or pronoun that receives the action. Without the object, the sentence feels incomplete or the action seems unfinished.

Test: Ask “[verb] what?” or “[verb] whom?” after the verb. If there is an answer, the verb is transitive.

Examples:

• She read the report from start to finish. → read what? the report ✓
• He kicked the ball. → kicked what? the ball ✓
• She sent an email to the entire department. → sent what? an email ✓
• The teacher explained the concept twice. → explained what? the concept ✓

Some verbs are always transitive: resemble, comprise, lack, contain, suit — these always need an object

4.2.4 Intransitive Verb

An intransitive verb does not require a direct object. The action is complete in itself — it does not pass on to anything else.

Examples:

• She slept for nine hours straight. (slept what? — no answer needed)
• The baby laughed at the moving mobile.
• He arrived just as the doors were closing.
• Birds sing loudest just before sunrise.
• The engine stalled at the worst possible moment.

Dual-function verbs — transitive and intransitive: Many verbs function as both transitive and intransitive, depending on the sentence:

• She runs a company. → transitive (runs what? a company)
• She runs every morning. → intransitive (no object)
• He read the report. → transitive
• He read for hours. → intransitive

4.2.5 Linking Verb

Linking verbs (also called copular verbs) do not describe actions — they connect the subject to a word that describes or identifies it. That descriptive word is called the subject complement, which is usually an adjective (predicate adjective) or noun (predicate nominative).

The verb be and its forms — the most common linking verbs: is, am, are, was, were, been, being

• She is a talented architect.
• They were exhausted after the long climb.

Sense verbs used as linking verbs:

• The soup tastes salty after the extra seasoning.
• That idea sounds worth exploring carefully.
• The room smells of fresh paint.
• The blanket feels soft against the skin.

Other common linking verbs: seem, become, appear, remain, grow, stay, turn, prove

• He seems distracted and unfocused today.
• She became the youngest director in the firm’s history.
• The situation remains unclear despite the latest update.

The quick test: Replace the verb with is or was. If the sentence still makes grammatical sense, it was a linking verb.

• The soup tastes salty. → The soup is salty. ✓ → Linking verb
• She tasted the soup. → She is the soup. ✗ → Action verb (transitive)

4.2.6 Helping Verb (Auxiliary Verb)

Helping verbs (also called auxiliary verbs) never function as main verbs alone — they always accompany a main verb and help it express tense, voice, mood, questions, and negatives. There are three primary auxiliaries in English:

Be — forms continuous tenses and passive voice:

4.2.7 Modal Verb

Modal verbs are a special category of helping verb. They add a layer of meaning — expressing possibility, permission, ability, necessity, obligation, or willingness — that the main verb alone cannot convey. Modals have the following characteristics:

1. They never change form — no -s, -ing, or -ed endings
2. They are always followed by the bare infinitive (infinitive without to)
3. They do not use do/does/did to form questions or negatives — they invert directly

The modal verbs: can, could, may, might, will, would, shall, should, must, ought to, need (modal use), dare (modal use), used to

Expressing ability: She can speak four languages fluently. He could lift twice his body weight at his peak.

Expressing permission: May I leave the room for a moment? You can use my laptop if yours isn’t working.

Expressing possibility: It might rain this evening — take a jacket. She may already know about the changes.

Expressing obligation and necessity: You must submit the completed form before Friday. All staff should read the updated guidelines. We ought to leave before the traffic gets worse.

Expressing willingness and offers: Will you help me carry these boxes upstairs? Would you mind closing the window? Shall we begin the meeting now?

Expressing past habits: He used to cycle to work every single day. She would always bring flowers when she visited.

4.2.8 Regular Verb

Regular verbs form their past tense and past participle by adding -ed (or -d if the verb already ends in e) to the base form. This pattern is entirely predictable — if you know the base form, you know every other form automatically.

Pattern: base → past tense → past participle

Spelling adjustments:

• Verbs ending in a single consonant after a single stressed vowel → double the consonant: stop → stopped, run → ran (irregular), plan → planned
• Verbs ending in -y after a consonant → change y to i: study → studied, carry → carried

4.2.9 Irregular Verb

Irregular verbs do not follow the -ed pattern for their past tense and past participle. Their forms change unpredictably — sometimes the vowel shifts, sometimes the entire word changes, and sometimes all three forms are identical. They must be learned individually.

Common irregular verbs — grouped by pattern:

All three forms different:

Past tense and past participle the same:

All three forms the same:

4.2.10 Phrasal Verb

A phrasal verb is a verb combined with one or two particles (a preposition, adverb, or both) that together create a meaning entirely new — one that is different from the individual words.

With adverb particles: give up → to quit: She gave up trying to explain it. break down → to lose emotional control: He broke down during the conversation. call off → to cancel: They called off the match due to rain. turn down → to reject: She turned down the offer. put off → to postpone: He keeps putting off the difficult conversation.
