The 8 Parts of Speech Explained for High School Students

This article breaks down the eight parts of speech in an easy-to-understand way. With clear definitions and useful examples, this guide is perfect for high school students who want to improve their grammar skills.

What Are Parts of Speech?

Every word in English fits into a category based on how it's used. These categories are called parts of speech. They help us figure out how words connect, what role they play, and how to use them correctly.

Here are the 8 main parts of speech in English:

1. Nouns
2. Pronouns
3. Verbs
4. Adjectives
5. Adverbs
6. Prepositions
7. Conjunctions
8. Interjections

Let’s take a closer look at each one.

1.  Nouns – The Naming Words

What they do: Nouns are words that name people, places, things, or ideas.

Examples:

•     People: teacher, friend
•     Places: beach, school
•     Things: pen, phone
•     Ideas: freedom, love

In a sentence:

•     The dog barked loudly.
•     Honesty is a great quality.

2. Pronouns – Shortcuts for Nouns

What they do: Pronouns take the place of nouns so you don’t have to repeat the same words over and over.

Examples:

•     he, she, it, we, you, they
•     mine, hers, theirs
•     myself, himself, ourselves

In a sentence:

•     Emily is kind. She always helps others.
•     That book is yours, not mine.

Grammar tip: Pronouns should always match the noun they replace in number and gender.

3. Verbs – Action and State Words

What they do: Verbs tell us what the subject is doing or what state it's in.

Types of verbs:

1.     Action verbs: run, jump, write
2.     Being verbs: am, is, are, was
3.     Helping verbs: can, will, have

In a sentence:

•     They play football every weekend.
•     She is very tired today.

4. Adjectives – Words That Give Details

What they do: Adjectives are descriptive words that give more information about a noun or pronoun. They tell us what something looks like, how many there are, or what kind it is.

Examples:

•     yellow, massive, silly, ancient, several

In context:

•     The massive elephant walked through the forest.
•     She packed an old bag for the trip.

Helpful hint:

•     Adjectives answer key questions such as:
•     What type? → vintage car
•     How many? → seven books
•     Which one? → this pen

5. Adverbs – Words That Add More Meaning

What they do: Adverbs enhance verbs, adjectives, or even other adverbs by showing how, when, where, or to what extent something happens.

Examples:

•     rapidly, yesterday, extremely, cheerfully, seldom

In context:

•     He quickly responded to the question.
•     She frequently visits her grandmother.

note: While many adverbs end with -ly , like slowly or carefully, others such as never, here, and soon don’t follow that pattern.

6. Prepositions – Positioning Words in Sentences

What they do: Prepositions link a noun or pronoun to the rest of the sentence and typically show direction, location, time, or cause.

Examples:

•     underneath, near, during, after, across

In context:

•     The dog hid beneath the bed.
•     We arrived after the meeting started.

Note: Prepositions form part of a phrase, like after dinner or in the room, and are followed by a noun or pronoun.

7. Conjunctions – Connecting Thoughts

What they do: Conjunctions join together words, groups of words, or full ideas. They help sentences sound smoother and more logical.

Types include:

1.     Coordinating: and, but, or
2.     Subordinating: although, while, because
3.     Correlative: both…and, whether…or

In context:

•     I enjoy reading, but I prefer writing.
•     She stayed indoors because it was cold outside.

Insight: Using conjunctions allows you to build longer, more complex sentences without confusion.

8. Interjections – Expressing Instant Reactions

What they do: Interjections are brief words or sounds that show strong emotion or spontaneous reactions like surprise, excitement, or frustration.

Examples:

•     Wow! Yikes! Hmm! Oops! Hooray!

In context:

•     Yikes! That was a loud noise.
•     Oops! I dropped my pen.

Keep in mind:

These expressions often stand alone and are usually followed by an exclamation mark, especially in informal or spoken English.
