Every word in English has a job. The parts of speech are the names for those jobs. There are eight main parts of speech, and knowing what each one does will help you write better, speak more clearly and pick up more marks in KPSEA and KJSEA English papers.
1. Nouns — naming words.
A noun is the name of a person, place, thing or idea. Examples: boy, Nairobi, table, honesty, mathematics, Kenya, love.
Types of nouns:
- Common nouns — general names: boy, town, book.
- Proper nouns — specific names, always capitalised: Wanjiru, Mombasa, Saturday.
- Concrete nouns — things you can touch: chair, water, phone.
- Abstract nouns — ideas or feelings you cannot touch: freedom, happiness, fear.
- Collective nouns — name a group: a flock of birds, a herd of cattle, a team of players.
2. Pronouns — words that replace nouns.
A pronoun is used instead of a noun so we don't repeat the noun every time. Examples: I, you, he, she, it, we, they, me, him, her, us, them, this, that, who, which.
Instead of "Wanjiru took Wanjiru's bag", we say: "Wanjiru took her bag."
3. Verbs — action or being words.
A verb is a word that shows an action (run, eat, write) or a state of being (am, is, are, was, were). Every sentence MUST have a verb.
- Action verbs: kick, speak, cook, dance.
- Linking verbs (also called "be" verbs): am, is, are, was, were, been.
- Helping verbs: will, have, do, can, should — they help the main verb.
4. Adjectives — describing words.
An adjective describes a noun or pronoun. Examples: tall, red, clever, Kenyan, three. In the phrase "a tall boy", tall tells us about the boy.
5. Adverbs — words that describe verbs (and adjectives and other adverbs).
An adverb usually tells us how, when, where or how often something happens. Examples: quickly, yesterday, here, always. Many adverbs end in -ly: carefully, slowly, happily — but not all of them (fast, hard, well).
6. Prepositions — words that show position or relationship.
A preposition comes before a noun or pronoun and shows how that noun connects to other words in the sentence. Examples: in, on, under, over, between, behind, with, by, to, from, across. "The cat is under the table." "We walked across the field."
7. Conjunctions — joining words.
A conjunction joins words, phrases or sentences. The most common are and, but, or, because, so, although, while, if, when. "I love ugali and sukuma wiki." "She ran fast but she still missed the bus."
8. Interjections — exclamations.
An interjection is a short word that shows strong feeling. Examples: Oh!, Wow!, Ouch!, Hooray!. They usually stand alone or at the start of a sentence and are followed by an exclamation mark.
The same word can be different parts of speech:
- I drink water. → noun
- I water the plants. → verb
The job a word does in a sentence tells you its part of speech — not the spelling.
Common student mistakes to avoid:
- Calling every word ending in -ly an adverb. Some adjectives end in -ly (friendly, lovely, lonely).
- Forgetting that "be" verbs (am, is, are, was, were) ARE verbs.
- Mixing up who (pronoun) with whose (adjective showing possession).
- Listing nouns as "people, places, things" only — they also include ideas: love, hope, freedom.
CBC Grade 4 introduces nouns, verbs and adjectives; Grade 5 adds adverbs and pronouns; Grade 6 covers prepositions, conjunctions and interjections — and the way the same word can do different jobs; Grade 7–9 extends to phrases, clauses and sentence structures for KJSEA.
