Key Differences
Adjectives are used to describe or modify nouns and pronouns, adding specificity and detail. They can tell us what kind, which one, how many, or whose about the nouns they modify. Whereas adverbs primarily modify verbs, adjectives, or other adverbs, providing additional information about how, when, where, why, or to what extent an action is performed.
An adjective can modify a noun in a sentence directly (e.g., "a red apple") or be linked to a noun by a verb (e.g., "The apple is red"). On the other hand, adverbs can modify a verb directly (e.g., "She runs quickly") or modify an adjective or another adverb (e.g., "She is very fast").
Adjectives are not used to modify verbs, which is a fundamental difference from adverbs. For example, "She sings beautiful" is incorrect, whereas "She sings beautifully" (adverb modifying the verb sings) is correct. In contrast, "beautiful song" (adjective modifying the noun song) is correct.
Adjectives usually appear directly before the noun they modify or after linking verbs such as be, seem, look, feel, etc., to describe the subject. Adverbs, however, can move around in a sentence without changing the sentence's meaning significantly, though their placement can emphasize different aspects of what's being described.
The formation of adverbs from adjectives often involves adding "-ly" to the end of an adjective (e.g., quick to quickly, happy to happily). However, there are many exceptions, and some words can function as both adjectives and adverbs without changing form (e.g., "fast").
