Question

Adjectives are words that describe ____________
A. Nouns
B. Pronouns
C. Verbs
D. Prepositions

Answer 1

Hint: Adjectives are words that describe the qualities or states of being of nouns: enormous, doglike, silly, yellow, fun, fast. They can also describe the quantity of nouns: many, few, millions, eleven.

Complete answer:
Option A (nouns) is the correct answer. An adjective is a word that modifies a noun or noun phrase or describes its referent. Its semantic role is to change information given by the noun. Adjectives are one of the main parts of speech of the English language, although historically they were classed together with nouns. Thus, Option A is right.
Option B (pronouns) is not the right answer. A pronoun is used as an adjective only if it modifies a noun. Thus, this option is also wrong.
Option C (verbs) is incorrect. Verbs are words used to describe an action, state, or occurrence, and form the main part of the predicate of a sentence, such as hear, become, happen etc; while Adjectives are words that describe or modify another person or thing in the sentence. So, it is clear that Option C is also wrong.
Option D (prepositions) is also wrong since prepositions can sometimes appear after adjectives to complete or elaborate on the ideas or emotions the adjective describes. The preposition always comes directly after the adjective and is typically followed by a noun or gerund to form a prepositional phrase.

Note:
Adjectives Use Certain Placement in a Sentence as follows :
1. Before a Noun.
2. If it comes immediately before a noun, it's likely an adjective.
3. Between an Article and a Noun.
4. Between a Possessive and a Noun.
5. Between a Demonstrative and a Noun.
6. Between an Amount and a Noun.
7. Adjectives Can Act As Complements.
