What part of speech in a basic English book?

In a basic English book, "part of speech" refers to the categories of Words based on their function in a sentence. The main parts of speech include nouns, verbs, adjectives, adverbs, pronouns, prepositions, conjunctions, and interjections. Each part plays a specific role, such as naming things (nouns), describing actions (verbs), or modifying nouns (adjectives). Understanding these categories is essential for constructing grammatically correct sentences.
