Explanation:
Parts of speech are categories of words that have similar grammatical properties.
Adverbs are words used to modify (describe) verbs, adjectives, and other adverbs (e.g. soon, hard).
Verbs are words used to express actions, occurrences, and states of being (e.g. to be, to have).
Prepositions are words used to link other words within the sentence and express the relationship between them (e.g. to, inside).
Adjectives are words used to modify nouns (e.g. difficult, leather).
Pronouns are words used instead of nouns and noun phrases (e.g. they).
Determiners are words used to introduce nouns (e.g. the).
