1. What Are Parts of Speech?
Every word in a sentence performs a particular grammatical function. Based on that function, words are traditionally classified into different categories called parts of speech.
The traditional classification contains eight major parts of speech:
| Part of Speech | Basic Function | Example |
|---|---|---|
| Noun | Names a person, place, thing, idea or entity. | student, Delhi, honesty |
| Pronoun | Used in place of a noun. | he, she, they, it |
| Verb | Expresses an action, state or occurrence. | run, is, become |
| Adjective | Describes or modifies a noun or pronoun. | honest, beautiful, five |
| Adverb | Modifies a verb, adjective, adverb or sometimes an entire clause. | quickly, very, fortunately |
| Preposition | Shows a relationship between words. | in, on, at, between |
| Conjunction | Connects words, phrases or clauses. | and, but, because |
| Interjection | Expresses sudden emotion or reaction. | Oh!, Wow!, Alas! |
A word’s part of speech is determined primarily by how it functions in the sentence, not simply by how the word looks or where it appears.
For example, the word “fast” can be an adjective in one sentence and an adverb in another.
Here, “fast” describes the noun “car” → Adjective.
Here, “fast” modifies the verb “drives” → Adverb.
2. Noun
A noun is a word used to name a person, place, thing, animal, idea, quality, activity or other entity.
2.1 Common Types of Nouns
| Type | Meaning | Examples |
|---|---|---|
| Proper Noun | Name of a particular person, place or entity. | Rahul, India, Delhi |
| Common Noun | General name of a person, place or thing. | boy, city, country |
| Collective Noun | Name of a group considered as a unit. | team, committee, army |
| Abstract Noun | Name of a quality, state, idea or concept. | honesty, wisdom, freedom |
| Material Noun | Name of a material or substance. | gold, water, iron |
Nouns become especially important in later chapters on: number, subject-verb agreement, articles, pronouns, possessives and error detection.
3. Pronoun
A pronoun is a word used in place of a noun or noun phrase, usually to avoid unnecessary repetition.
3.1 Common Types of Pronouns
| Type | Examples |
|---|---|
| Personal | I, we, you, he, she, it, they |
| Possessive | mine, yours, his, hers, ours, theirs |
| Reflexive | myself, yourself, himself, herself, themselves |
| Demonstrative | this, that, these, those |
| Relative | who, whom, whose, which, that |
| Interrogative | who, whom, whose, which, what |
| Indefinite | someone, anyone, everyone, nobody, many |
| Reciprocal | each other, one another |
Pronouns are not simply “words that replace nouns.” Their grammatical form must agree correctly with the noun they refer to.
This concept will become extremely important in the dedicated Pronoun chapter later in the course.
4. Verb
A verb generally expresses an action, state or occurrence.
4.1 Main Verb and Helping Verb
A sentence can contain a main verb along with one or more helping verbs.
“is” → Helping verb
“reading” → Main verb
“have” → Helping verb
“completed” → Main verb
Verbs are central to tenses, subject-verb agreement, voice, narration, modals, conditionals and error detection.
5. Adjective
An adjective modifies or describes a noun or pronoun.
“Intelligent” describes the noun “student.”
“New” describes the noun “car.”
5.1 Adjectives Can Express Different Information
- Quality: beautiful, honest, difficult
- Quantity: some, much, little
- Number: one, two, first, second
- Demonstration: this, that, these, those
- Possession: my, your, his, their
Some words traditionally classified as adjectives are also treated as determiners in modern grammar. We will study determiners separately because they have major importance in competitive-exam grammar.
6. Adverb
An adverb commonly modifies a verb, adjective, another adverb, or sometimes an entire clause.
6.1 Adverb Modifying a Verb
“Beautifully” tells us how she sings.
6.2 Adverb Modifying an Adjective
“Very” modifies the adjective “difficult.”
6.3 Adverb Modifying Another Adverb
“Very” modifies the adverb “quickly.”
6.4 Adverb Modifying an Entire Clause
“Fortunately” expresses the speaker’s attitude towards the entire statement.
Many adverbs end in -ly, but this is not a universal rule.
“Fast” and “hard” function as adverbs in these sentences.
7. Preposition
A preposition generally shows a relationship between a noun/pronoun and another word in the sentence.
7.1 Common Relationships Expressed by Prepositions
- Place — in, on, under, behind
- Time — at, on, in, before, after
- Direction — to, towards, into
- Source — from
- Association — with
- Purpose — for
- Comparison — than
Prepositions are one of the most frequently tested areas in grammar through fillers, error detection, sentence improvement and phrase replacement.
8. Conjunction
A conjunction connects words, phrases or clauses.
8.1 Coordinating Conjunctions
These connect elements of relatively equal grammatical importance.
8.2 Subordinating Conjunctions
These introduce dependent clauses and establish relationships such as time, reason, condition or contrast.
8.3 Correlative Conjunctions
These work in pairs.
- either…or
- neither…nor
- both…and
- not only…but also
- whether…or
Correlative conjunctions often interact with subject-verb agreement and parallelism. These will be studied in detail in later chapters.
9. Interjection
An interjection is a word or expression used to express a sudden emotion, reaction or feeling.
Interjections are relatively less important than grammar areas such as verbs, prepositions and conjunctions in most competitive examinations.
Learn the basic concept, but do not spend disproportionate preparation time on interjections. Your time is better invested in high-frequency areas such as verbs, tenses, subject-verb agreement, prepositions and modifiers.
10. Determiners
Determiners are words placed before nouns to help identify, quantify or specify them.
10.1 Common Determiners
| Category | Examples |
|---|---|
| Articles | a, an, the |
| Demonstratives | this, that, these, those |
| Possessives | my, your, his, her, our, their |
| Quantifiers | some, any, much, many, few, little |
| Distributives | each, every, either, neither |
| Numbers | one, two, first, second |
Determiners are extremely important for articles, countability, quantifiers, noun number, fillers and error detection.
We will therefore devote separate chapters to Articles and Determiners later in the course.
11. The Same Word Can Have Different Functions
One of the most important concepts for competitive exams is that a word does not permanently belong to one part of speech. Its grammatical function depends on the sentence.
Example 1: “Fast”
“Fast” describes “car” → Adjective
“Fast” modifies “drives” → Adverb
Example 2: “Light”
“Light” describes the bag → Adjective
“Light” expresses an action → Verb
Example 3: “Work”
“Work” is a thing/concept → Noun
“Work” expresses an action → Verb
Never identify the part of speech merely by memorising the word. Look at what the word is doing in the sentence.
12. How Word Forms Change
English frequently changes the form of a word to perform a different grammatical function.
| Noun | Verb | Adjective | Adverb |
|---|---|---|---|
| success | succeed | successful | successfully |
| beauty | beautify | beautiful | beautifully |
| decision | decide | decisive | decisively |
| care | care | careful | carefully |
Competitive exams frequently test whether the correct word form has been used.
For example:
Here, a noun is required after “remarkable.”
Here, an adverb is required to modify “performed.”
13. Identify Multiple Parts of Speech in a Sentence
Let’s analyse a complete sentence.
| Word | Part of Speech | Function |
|---|---|---|
| The | Determiner | Specifies the noun “company.” |
| highly | Adverb | Modifies “successful.” |
| successful | Adjective | Describes “company.” |
| company | Noun | Names an entity. |
| launched | Verb | Expresses the action. |
| a | Determiner / Article | Introduces “product.” |
| new | Adjective | Describes “product.” |
| product | Noun | Names a thing. |
| yesterday | Adverb | Indicates when the action occurred. |
When identifying a word’s grammatical category, ask:
- What does the word mean?
- What word is it modifying or relating to?
- What role is it performing in the sentence?
14. Commonly Confused Parts of Speech
14.1 Adjective vs Adverb
“Careful” describes the noun “driver” → Adjective.
“Carefully” modifies the verb “drives” → Adverb.
14.2 Adjective vs Determiner
“Many” determines the quantity of the noun “students.” It is generally treated as a determiner in modern grammar.
14.3 Pronoun vs Determiner
“This” determines which book → Determiner.
“This” stands independently in place of a noun phrase → Pronoun.
14.4 Preposition vs Adverb
“Inside” introduces the noun phrase “the room” and functions as a preposition.
Here, “inside” does not introduce an object and functions adverbially.
15. Why Parts of Speech Matter in Competitive Exams
Parts of speech are rarely tested only as a simple “identify the noun” question. Their real importance lies in helping you understand grammatical relationships.
Error Detection
You need to know whether the sentence requires a noun, adjective, adverb, verb or another form.
The sentence requires an adverb: successfully.
Fillers
The grammatical role required by a blank often helps eliminate incorrect options.
“Spoke” is a verb, so an adverb is required: confidently.
Cloze Test
Context alone may not be enough. You also need to determine what type of word can grammatically fit the blank.
Sentence Improvement
A sentence may contain the correct idea but the wrong grammatical form.
Vocabulary Questions
Knowing whether a word is functioning as a noun, verb, adjective or adverb helps you understand its meaning and correct usage.
Parts of speech are the building blocks of grammar. The later chapters on tenses, subject-verb agreement, articles, prepositions, modifiers, error detection, fillers and cloze tests will repeatedly build on what you learn here.
16. Common Exam Traps
Most “-ly” words are adverbs, but not all.
“Lovely” describes “person” → Adjective.
The same word can perform different functions.
Verb.
Noun.
Adjective → describes “driver.”
Adverb → modifies “drives.”
Always examine the word’s function in the sentence.
Determiner.
Pronoun.

24. Final Takeaway
A word’s part of speech depends on the function it performs in a sentence.
Do not identify words in isolation. Always look at the surrounding words and ask what grammatical role the word is performing.
This principle will appear repeatedly throughout the IBPS Hub English & Verbal Ability course.
