A complete guide to the nine grammatical building blocks of English — covering definitions, types, rules, and common errors tested in competitive exams, entry tests, and job assessments.
Every word in an English sentence belongs to a category — and that category determines how the word behaves, what role it plays, and how it connects to everything around it. Parts of speech are the building blocks of all English grammar, and every advanced topic (tenses, sentence correction, subject-verb agreement) depends on knowing them precisely. Competitive exams test parts of speech both directly (identify the part of speech of the underlined word) and indirectly (in error-spotting, sentence correction, and fill-in-the-blank questions).

This topic covers:
Parts of speech are tested directly and indirectly across NTS, PPSC, FPSC, CSS, PMS, and all major university and military entry tests — as identification questions, error-correction questions, and fill-in-the-blank tasks.
| Subtopic | One-line definition | Key signal/clue word |
|---|---|---|
| Nouns | Names a person, place, thing, quality, or idea | Subject/object position; answers "Who?" or "What?" |
| Pronouns | Replaces a noun to avoid repetition | "he," "she," "it," "who," "whom," "each," "everyone" |
| Adjectives | Describes or modifies a noun or pronoun | Answers "Which one?" "What kind?" "How many?" |
| Verbs | Expresses action, occurrence, or state of being | Action word; "is/are/was/were," modal words |
| Adverbs | Modifies a verb, adjective, or another adverb | Answers "How?" "When?" "Where?" "How often?" |
| Prepositions | Shows the relationship of a noun/pronoun to another element | "at," "on," "in," "by," "with," "to," "of," "for" |
| Conjunctions | Joins words, phrases, or clauses | FANBOYS; "although," "because," "unless," "either…or" |
| Interjections | Expresses sudden emotion; no grammatical role | Exclamation mark or comma; "Alas!" "Bravo!" "Oh!" |
| Determiners | Specifies or quantifies a noun before it is used | "a," "an," "the," "this," "my," "some," "each" |
Definition: A noun is a naming word — it names a person, place, thing, quality, or idea. It is the most fundamental part of speech; every sentence must have a noun functioning as its subject.
Types of Nouns
| Type | Definition | Examples |
|---|---|---|
| Proper | Specific name, always capitalized | Ali, Karachi, Google |
| Common | General name, not capitalized | city, teacher, table |
| Abstract | Cannot be seen or touched; names ideas/feelings | honesty, freedom, courage |
| Concrete | Perceived through the five senses | rain, stone, perfume |
| Collective | Names a group as one unit | team, jury, committee, flock |
| Countable | Can be counted; has singular & plural forms | book/books, child/children |
| Uncountable | Cannot be counted; NO plural form; always singular verb | water, advice, information, luggage, furniture, news |
| Compound | Two or more words forming one noun | toothpaste, mother-in-law, post office |
Functions in a Sentence
| Function | Example |
|---|---|
| Subject | The teacher explained the rule. |
| Object | She loves music. |
| Object of preposition | He sat on the chair. |
| Appositive | My friend Ali, a doctor, arrived late. |
Examples
| Incorrect | Correct |
|---|---|
| He gave me many advices on the matter. | He gave me much advice on the matter. |
| She shared two informations with the team. | She shared two pieces of information with the team. |
| The committee are meeting at noon as one group. | The committee is meeting at noon as one group. |
| I bought three furnitures for my new room. | I bought three pieces of furniture for my new room. |
Common Mistake: Students add -s to uncountable nouns (informations, advices, luggages, furnitures) because they are translating directly from Urdu/regional language patterns where these words can be pluralised. In English, these nouns have no plural form whatsoever.
Exam Tip: Memorise the core uncountable nouns as a fixed list — advice, information, luggage, furniture, news, knowledge, equipment, evidence — and never add -s to any of them.
Definition: A pronoun is a word used in place of a noun to avoid unnecessary repetition. The noun it replaces is called its antecedent — and every pronoun must agree with its antecedent in number and gender.
Types of Pronouns
| Type | Examples |
|---|---|
| Personal | I, you, he, she, it, we, they |
| Possessive | mine, yours, his, hers, its, ours, theirs |
| Reflexive | myself, yourself, himself, herself, itself, ourselves, themselves |
| Relative | who, whom, which, that, whose |
| Interrogative | who, whom, what, which, whose (in questions) |
| Demonstrative | this, that, these, those |
| Indefinite | anyone, everyone, nobody, each, all, both, either, neither, several, none |
| Reciprocal | each other, one another |
Cases of Pronouns
| Case | Used for | Pronouns | Example |
|---|---|---|---|
| Subjective | Subject of a verb | I, you, he, she, it, we, they | She runs very fast. |
| Objective | Object of verb/preposition | me, you, him, her, it, us, them | They saw him at the station. |
| Possessive | Shows ownership | my/mine, your/yours, his, her/hers, its, our/ours, their/theirs | This book is mine. |
Who vs. Whom — Substitution Test
| Test | Rule |
|---|---|
| Replace with he/she | Use WHO |
| Replace with him/her | Use WHOM |
| "Whom did you call?" | You called HIM → him = WHOM ✓ |
| "Who is calling?" | HE is calling → he = WHO ✓ |
Examples
| Incorrect | Correct |
|---|---|
| Between you and I, this plan will not work. | Between you and me, this plan will not work. |
| Who did the manager promote last quarter? | Whom did the manager promote last quarter? |
| Everyone in all departments are expected to attend. | Everyone in all departments is expected to attend. |
| The award was given to Sana and I. | The award was given to Sana and me. |
Common Mistake: Using subjective case pronouns (I, he, she, we) after prepositions. Any pronoun following a preposition must be in the objective case — "between you and me," "for him," "with us," never "between you and I" or "with we."
Exam Tip: If you can remove the other person's name and the sentence still sounds right, you have the correct pronoun case — "The award was given to I" immediately sounds wrong; "The award was given to me" is clearly correct.
Definition: An adjective describes or modifies a noun or pronoun. It answers the questions: Which one? What kind? How many? How much? — and it always sits close to the noun it describes.
Degrees of Comparison
| Degree | Use | Rule | Examples |
|---|---|---|---|
| Positive | Basic form; no comparison | — | tall, fast, beautiful, intelligent |
| Comparative | Comparing TWO people/things | -er for short words; "more" for long words (3+ syllables) | taller, faster / more beautiful, more intelligent |
| Superlative | Comparing THREE or more | -est for short words; "most" for long words | tallest, fastest / most beautiful, most intelligent |
Irregular Adjectives (must memorise)
| Positive | Comparative | Superlative |
|---|---|---|
| good | better | best |
| bad | worse | worst |
| little | less | least |
| many / much | more | most |
| far | farther / further | farthest / furthest |
Two Key Errors to Avoid
| Error type | Wrong | Correct |
|---|---|---|
| Double comparative | more taller / most greatest / more better | taller / greatest / better |
| Comparing absolute adjectives | more unique / very perfect | unique / perfect (cannot be compared) |
Absolute adjectives that cannot be compared: unique, perfect, dead, round, empty, complete, infinite.
Examples
| Incorrect | Correct |
|---|---|
| She is more taller than her sister. | She is taller than her sister. |
| This is the most unique design I have ever seen. | This is a unique design I have ever seen. |
| He is the most hardest worker in the office. | He is the hardest worker in the office. |
| Her score was more better than mine in the test. | Her score was better than mine in the test. |
Common Mistake: Using both the -er/-est suffix AND "more/most" together in the same word (double comparative). This error most often occurs with two-syllable words where students are unsure whether to add -er or use "more," and so they use both to be safe — which is always wrong.
Exam Tip: If the comparative already has -er or -est at the end, you never need "more" or "most" — they cannot coexist.
Definition: A verb expresses an action, occurrence, or state of being. No sentence is grammatically complete without a verb — it is the engine of every clause and the foundation of all tense and voice questions.
Types of Verbs
| Type | Definition | Examples |
|---|---|---|
| Action Verbs | Physical or mental actions | run, think, decide |
| Linking Verbs | Connect subject to description (state of being) | is, am, are, was, were, seem, appear, become, feel, look, sound, taste, smell, remain |
| Helping/Auxiliary | Assist the main verb | have, has, had, do, does, did, will, would, shall, should, can, could, may, might, must |
| Transitive | Requires a direct object | She ate the apple. |
| Intransitive | No object needed | He slept. / Birds fly. |
| Modal Verbs | Express ability/possibility/obligation; always followed by BASE form | can, could, may, might, shall, should, will, would, must, ought to, used to |
Four Principal Forms
| Form | Also called | Used with | Example (write) |
|---|---|---|---|
| Base form | Infinitive | — | write |
| Past tense | Simple past | — | wrote |
| Past participle | Third form | have / has / had | written |
| Present participle | -ing form | is / are / was | writing |
Commonly Tested Irregular Verbs
| Base | Past | Past Participle |
|---|---|---|
| go | went | gone |
| take | took | taken |
| break | broke | broken |
| begin | began | begun |
| speak | spoke | spoken |
| rise | rose | risen |
| lay | laid | laid |
| lie | lay | lain |
The lie / lay pair is the most confused in exams — "lie" means to recline (lie, lay, lain); "lay" means to place something down (lay, laid, laid).
Examples
| Incorrect | Correct |
|---|---|
| He has went to the office already. | He has gone to the office already. |
| She have been working here since 2019. | She has been working here since 2019. |
| The sun was shined brightly all morning. | The sun shone brightly all morning. |
| He can to swim very fast in competitions. | He can swim very fast in competitions. |
Common Mistake: Using the simple past form where the past participle is required (after have/has/had). "He has went" is the single most common irregular verb error in exams — "went" is simple past; "gone" is the past participle needed after "has."
Exam Tip: After have / has / had, you must always use the past participle (third form) — never the simple past (second form). When in doubt, ask: "Is there a have/has/had before this verb?" If yes, use the third form.
Definition: An adverb modifies a verb, an adjective, or another adverb. It answers the questions: How? When? Where? To what extent? How often? — and its placement in the sentence significantly changes meaning.
Types of Adverbs
| Type | Answers | Examples |
|---|---|---|
| Manner | How? | quickly, carefully, well, loudly |
| Time | When? | now, soon, already, recently, still |
| Place | Where? | here, there, inside, abroad, above |
| Frequency | How often? | always, never, often, rarely, seldom |
| Degree | How much? | very, too, quite, almost, extremely, fairly |
| Interrogative | (asks questions) | when, where, how, why |
| Conjunctive | (connects clauses) | however, therefore, moreover, nevertheless, consequently, furthermore, otherwise |
Placement Rules
| Adverb type | Position | Example |
|---|---|---|
| Manner | After the verb or object | She speaks clearly. / He completed the task quickly. |
| Frequency | Before main verb; after auxiliary/be verb | He always arrives on time. / She is never rude. / They have often visited. |
| Degree | Immediately before the word it modifies | The exam was quite difficult. |
Misplaced Adverb = Changed Meaning
| Wrong placement | Meaning | Correct placement | Meaning |
|---|---|---|---|
| She only told me the truth. | She told no one else | She told me only the truth. | She revealed nothing false |
| He nearly drove 400 kilometres. | He almost got in the car | He drove nearly 400 kilometres. | He drove close to 400 km |
Examples
| Incorrect | Correct |
|---|---|
| I can't hardly hear you from this distance. | I can hardly hear you from this distance. |
| She only submitted three documents. (when four were needed) | She submitted only three documents. |
| He speaks English very good. | He speaks English very well. |
| They have visited often the principal's office. | They have often visited the principal's office. |
Common Mistake: Using "good" instead of "well" to modify verbs. "Good" is an adjective (modifies nouns); "well" is the adverb form (modifies verbs). "He speaks English good" is a part-of-speech error — the verb "speaks" needs an adverb, not an adjective.
Exam Tip: Hardly, scarcely, and barely are themselves negative words — never pair them with "not," "can't," or "don't." One negative per clause only.
Definition: A preposition shows the relationship between a noun or pronoun and another element in the sentence — expressing time, place, direction, manner, or cause. A preposition always has an object (a noun or pronoun that follows it), and together they form a prepositional phrase.
Categories
| Category | Common prepositions |
|---|---|
| Time | at, on, in, since, for, by, until, during, before, after |
| Place | at, on, in, above, below, between, beside, behind, in front of, under, over, near |
| Direction | to, into, onto, toward, through, across, along, up, down |
| Manner | by, with, without, like |
| Cause | because of, due to, owing to, on account of |
At / On / In — Most Tested Distinction
| Use | AT | ON | IN |
|---|---|---|---|
| Time | Specific clock time / point: at 8am, at noon, at night | Days and dates: on Monday, on 5th May, on my birthday | Months, years, seasons, periods: in June, in 2025, in winter |
| Place | Specific point: at the station, at home, at the door | Surface: on the table, on the wall, on the floor | Enclosed space: in the room, in Karachi, in the box |
Fixed Preposition Pairs (must memorise)
| Word | Preposition | Word | Preposition |
|---|---|---|---|
| good | AT | interested | IN |
| different | FROM | married | TO |
| afraid | OF | depend | ON |
| senior | TO | inferior | TO |
| superior | TO | consist | OF |
| apply | FOR | apologise | FOR / TO |
Note: "arrive AT" is used for small/specific places; "arrive IN" is used for cities or countries.
Examples
| Incorrect | Correct |
|---|---|
| He is good in mathematics and always scores well. | He is good at mathematics and always scores well. |
| The accident happened at 5th April last year. | The accident happened on 5th April last year. |
| She got married with a doctor she met in university. | She got married to a doctor she met in university. |
| He is senior than me by three years of experience. | He is senior to me by three years of experience. |
Common Mistake: Translating preposition usage directly from Urdu or another native language. English locks specific adjectives to specific prepositions, and these pairs must be learned by heart as single units, not broken apart.
Exam Tip: Any pronoun after a preposition must be in objective case — "between you and me," never "between you and I." After any preposition, use: me, him, her, us, them.
Definition: A conjunction is a joining word. It connects words, phrases, or clauses — and the type of conjunction used determines the relationship between the two parts and the punctuation required.
Coordinating Conjunctions — FANBOYS (join equal elements)
| Letter | Conjunction | Relationship | Example |
|---|---|---|---|
| F | For | Cause/reason | She rested, for she was exhausted. |
| A | And | Addition | He studied and passed the exam. |
| N | Nor | Negative addition | He cannot sing, nor can he dance. |
| B | But | Contrast | She is quiet but very observant. |
| O | Or | Alternative | Tea or coffee? |
| Y | Yet | Surprise | It was freezing, yet he wore no coat. |
| S | So | Result | It rained heavily, so we stayed home. |
Rule: Place a comma before a coordinating conjunction when it joins two independent clauses.
Subordinating Conjunctions (introduce dependent clauses): because, although, since, unless, while, if, when, before, after, until, though, even though, as soon as, as long as, provided that, so that, wherever, whenever
| Clause order | Comma rule | Example |
|---|---|---|
| Subordinate clause first | Comma after it | Although it rained, they continued playing. |
| Subordinate clause second | No comma needed | They continued playing although it rained. |
Correlative Conjunctions (always in pairs)
| Pair | Example |
|---|---|
| either…or | Either he goes, or I go. |
| neither…nor | Neither Ali nor Sana attended the meeting. |
| both…and | Both the teacher and the student agreed. |
| not only…but also | Not only did she win, but she also broke the record. |
| whether…or | Whether you like it or not, rules must be followed. |
| as…as | She is as intelligent as her brother. |
| no sooner…than | No sooner had he left than it started raining. |
Verb Agreement with Correlatives: the verb agrees with the nearest (second) subject — Neither Ali nor the students WERE informed. Neither the students nor Ali WAS informed.
Examples
| Incorrect | Correct |
|---|---|
| She was tired but however she kept working late. | She was tired, but she kept working late. |
| Neither Ali or Sana attended the ceremony. | Neither Ali nor Sana attended the ceremony. |
| Although she was qualified but she was not selected. | Although she was qualified, she was not selected. |
| He is not only intelligent but also he works with discipline. | He is not only intelligent but also hardworking. |
Common Mistake: Using "although" and "but" together in the same sentence ("Although…but…") — these are two different ways to express contrast and are never used together. One conjunction per contrast clause only.
Exam Tip: "Neither" always pairs with "nor" — never with "or." "Either" always pairs with "or" — never with "nor." Mixing these pairs is one of the most frequently planted errors in MCQ exams.
Definition: An interjection is a word or phrase that expresses a sudden or strong emotion — joy, surprise, pain, sorrow, approval, or greeting. It has no grammatical connection to the rest of the sentence and can be removed without changing the sentence's meaning or structure.
Punctuation Rule
| Emotion strength | Punctuation | Example |
|---|---|---|
| Strong emotion | Exclamation mark (!) | Hurray! We won the championship! |
| Mild emotion | Comma (,) | Well, that was unexpected. |
Common Interjections by Emotion
| Emotion | Interjections |
|---|---|
| Joy / Excitement | Hurray! Wow! Yay! Bravo! |
| Surprise | Oh! Ah! Gosh! What! Indeed! |
| Pain | Ouch! Ugh! Ew! |
| Approval / Praise | Bravo! Well done! Excellent! |
| Greeting | Hello! Hi! Good morning! |
| Sorrow / Regret | Alas! Oh dear! |
| Silence / Attention | Shh! Hush! Ahem! |
| Hesitation | Hmm… Well… Uh… |
Key feature: remove the interjection — the remaining sentence must still be grammatically complete and unchanged.
Examples
| Incorrect | Correct |
|---|---|
| Alas, she won the prize! (expressing joy) | Hurray! She won the prize! |
| Ouch I hurt my hand on the sharp edge. | Ouch! I hurt my hand on the sharp edge. |
| Bravo, the building collapsed. (expressing disaster) | Alas! The building collapsed. |
| Well! I think we should reconsider the plan calmly. | Well, I think we should reconsider the plan calmly. |
Common Mistake: Choosing the wrong interjection for the emotion in the sentence — for example, using "Alas!" (sorrow) in a sentence describing success, or "Hurray!" in a sentence describing misfortune.
Exam Tip: Match the interjection to the emotion of the whole sentence, not just the first word — read the complete sentence before selecting or identifying an interjection.
Definition: A determiner is placed before a noun to specify which one is being referred to, or how many of something exist. Unlike adjectives, determiners do not describe the quality of a noun — they identify or quantify it.
Types of Determiners
| Type | Examples |
|---|---|
| Articles | a, an, the |
| Demonstrative | this, that, these, those |
| Possessive | my, your, his, her, its, our, their |
| Quantifiers | some, any, many, much, few, little, several, all, both, each, every, enough, no |
| Numeral | one, two, first, second, third... |
| Interrogative | which, what, whose (before a noun) |
| Distributive | each, every, either, neither |
Articles — Most Tested Determiner
| Article | Used before | Examples |
|---|---|---|
| A | Consonant SOUNDS (not letters) | a car, a book, a university (/j/ sound), a one-time event |
| AN | Vowel SOUNDS (not letters) | an apple, an hour (/aʊ/ sound), an honest man, an MBA |
| THE | Specific / previously mentioned / unique nouns | the sun, the president, the boy I met yesterday |
No article needed: abstract nouns used generally (Honesty is the best policy). Superlatives always need "the" (the tallest, the most intelligent).
Few vs. A Few / Little vs. A Little
| Word | Meaning | Tone | Example |
|---|---|---|---|
| Few | Not many | Negative (scarcity) | Few students attended. (most stayed away) |
| A few | Some | Positive (sufficient) | A few students attended. (at least some did) |
| Little | Not much | Negative (scarcity) | There is little hope of recovery. |
| A little | Some amount | Positive (sufficient) | There is a little hope of recovery. |
Examples
| Incorrect | Correct |
|---|---|
| He is a honest man who always keeps his promises. | He is an honest man who always keeps his promises. |
| She is an university graduate with years of experience. | She is a university graduate with years of experience. |
| The honesty is the best policy in all circumstances. | Honesty is the best policy in all circumstances. |
| Few students attended, but it was enough to begin. | A few students attended, but it was enough to begin. |
Common Mistake: Choosing a/an based on the written first letter of the word instead of how it is pronounced. "University" starts with the letter U (vowel) but begins with the sound /j/ (consonant) → use "a." "Hour" starts with the letter H (consonant) but begins with the sound /aʊ/ (vowel) → use "an." Spelling is irrelevant — only sound matters.
Exam Tip: Say the word out loud in your head before choosing a or an — the sound, not the letter, makes the decision every time.
The following parts of speech are frequently confused in identification and error-correction questions:
| Feature | Adjective | Adverb | Determiner |
|---|---|---|---|
| What does it modify? | Noun or pronoun | Verb, adjective, or another adverb | Noun only (appears before it) |
| Does it describe quality? | Yes | Yes (of action/degree) | No — it identifies or quantifies |
| Examples | beautiful, tall, honest | quickly, very, almost | the, this, my, some, each |
| Position in sentence | Before the noun or after a linking verb | Before adjective/adverb; after verb or object | Always directly before the noun |
| Key test | Can it follow "The ___ noun"? | Can it answer How/When/Where/How much? | Can it answer "Which one?" or "How many?" without describing quality? |
| Common confusion | "He is a good player" (adj) | "He plays well" (adv — not "good") | "This book" (determiner) vs "This is mine" (pronoun) |
| Feature | Pronoun | Determiner (Possessive) |
|---|---|---|
| Example | mine, his, theirs | my, his, their |
| Followed by a noun? | No — stands alone | Yes — always followed by a noun |
| Example sentence | "This book is mine." | "This is my book." |
Parts of speech are not just a labelling exercise — they are the grammar logic that underlies every sentence correction, fill-in-the-blank, and error-spotting question in every competitive exam. Master the rules in each category and you will recognise errors across all question types automatically.
