This document defines and provides examples of different parts of speech, including nouns, pronouns, verbs, adjectives, and adverbs. Nouns refer to people, places or things. Pronouns are used in place of nouns. Verbs express actions or states of being, and can be action verbs, linking verbs, or helping verbs. Adjectives describe nouns and pronouns by answering questions like what kind and which one. Adverbs modify verbs, adjectives, and other adverbs by describing when, how, where, or to what extent. The document concludes with examples of sentences and questions to test understanding of parts of speech.
