Parts of speech
Parts of speech are the categories English words are grouped into according to their function in a sentence. There are eight main types: nouns, pronouns, verbs, adjectives, adverbs, prepositions, conjunctions and interjections. Knowing a word's part of speech shows how it can be used, where it goes in a sentence, and how it relates to other words.
Types of parts of speech
Noun
A word that names a person, place, thing, or idea.
e.g. teacher, London, happiness
Pronoun
A word that replaces a noun to avoid repetition.
e.g. she, they, it
Verb
A word that expresses an action, state, or occurrence.
e.g. run, seem, become
Adjective
A word that describes or modifies a noun or pronoun.
e.g. beautiful, three, difficult
Adverb
A word that modifies a verb, adjective, or another adverb, often showing manner, time or place.
e.g. quickly, very, yesterday
Preposition
A word that shows the relationship between a noun/pronoun and other words in the sentence.
e.g. in, under, between
Conjunction
A word that connects words, phrases, or clauses.
e.g. and, but, because
Interjection
A word or short phrase that expresses strong emotion, usually standing alone.
e.g. Wow!, Ouch!, Oh no!
Rules to remember
- A word's part of speech depends on how it functions in a sentence, not on its spelling alone; for example, 'run' can be a verb or a noun.
- Nouns and pronouns act as subjects or objects, while verbs show the action or state linked to them.
- Adjectives come before nouns or after linking verbs, whereas adverbs modify verbs, adjectives, or other adverbs.
- Prepositions always introduce a noun phrase (a prepositional phrase), never a full clause on their own.
- Conjunctions join equal elements (coordinating) or attach a dependent clause to a main clause (subordinating).
Examples in sentences
| Example | How it works |
|---|---|
| The dedicated teacher explained the lesson clearly. | 'Teacher' is a noun, 'dedicated' and 'the' modify it as adjectives/determiners, and 'clearly' is an adverb modifying the verb 'explained'. |
| She quickly finished her homework before dinner. | 'She' is a pronoun, 'quickly' is an adverb, 'finished' is a verb, and 'before' is a preposition introducing 'dinner'. |
| He is intelligent, but he rarely studies. | 'Intelligent' is an adjective, and 'but' is a coordinating conjunction linking two clauses. |
| Wow, that was an incredible performance! | 'Wow' is an interjection expressing surprise, and 'incredible' is an adjective describing 'performance'. |
| Because it was raining, we stayed inside. | 'Because' is a subordinating conjunction joining the dependent clause to the main clause. |
| The cat sat under the old wooden table. | 'Under' is a preposition showing position, and 'old' and 'wooden' are adjectives describing 'table'. |

Why this matters for IELTS
Understanding parts of speech helps you choose the correct word form (noun, verb, adjective or adverb) when building sentences, which directly affects your Grammatical Range and Accuracy score in IELTS Writing and Speaking. Examiners notice when candidates confuse forms, such as using an adjective where an adverb is needed. Being able to identify and correctly use each part of speech allows you to construct more varied, accurate sentences and avoid basic errors that can lower your band score.
