The parts of speech are the categories of the words in traditional English grammar. We can divide them into eight main groups (or nine, if you count determiners): nouns, pronouns, verbs, adjectives, adverbs, prepositions, conjunctions, and interjections. The following chart contains the parts of speech, their functions, and some examples of words and sentences.

There is a discussion about determiners being a part of speech since they have similar functions to adjectives, articles, and pronouns. There are four types of determiners in English: articles, demonstratives, quantifiers, and possessives.

The dog is barking.
I have some oranges.

As we saw with the determiners, many words in English have more than one job. For example, "close" can be a verb, a noun, an adjective, and even an adverb. The spelling is the same, but the meanings are different.

  • VERB: Can you please close the door?

  • NOUN: It came to a close.

  • ADJECTIVE: We are close friends.

  • ADVERB: Don't be so close to each other.

It is crucial to understand the parts of speech, so you define the exact word order and the correct use of punctuation in a sentence. Now, try to write sentences using as many parts of speech as you can. Here is an example:
