Final answer:
Adjectives and adverbs modify nouns and pronouns. Adjectives describe nouns, with examples like 'delicious' and 'wary,' and can form phrases with qualifiers and comparatives. Pronouns act as substitutes for nouns and have antecedents they refer to.
Step-by-step explanation:
Adjectives and adverbs are the parts of speech that typically modify nouns and pronouns. For example, in the sentence 'That is my car,' the word 'that' functions as a pronoun and is the subject of the sentence, but in 'That car is mine,' 'that' becomes an adjective because it modifies the noun 'car.' Similarly, adverbs can modify adjectives, verbs, or other adverbs, often providing information about how, when, where, or to what extent something happened. An example of an adverb modifying an adjective could be, 'She is extremely happy,' where 'extremely' is the adverb modifying the adjective 'happy.'
Adjectives can be identified by their characteristic endings such as '-ous,' '-ish,' '-ful,' and '-ary.' They can also be modified with qualifiers and comparative words to form adjective phrases, like 'a more reliable car,' where 'more' is the comparative word modifying the adjective 'reliable.' The importance of pronouns lies in their role as substitutes for nouns, while their antecedent is the noun or pronoun they replace.
