It explains that every word in a sentence has a specific role and gives examples of how words fulfill different parts of speech, such as nouns representing people, places or things, verbs showing actions or states of being, and adjectives describing nouns. The purpose is to give students a working vocabulary and improve their understanding of grammar.
