Edited by Tayyaba Rehman — By Fiza Rafique — Updated on April 15, 2024
Adjectives modify nouns to specify characteristics (e.g., green, large), while nouns name people, places, things, or ideas (e.g., car, joy).

Key Differences
An adjective serves to describe or modify the qualities of a noun, adding detail to help visualize or understand it better. For instance, in "red apple," "red" describes the apple. On the other hand, a noun identifies a subject or object in speech or writing, representing people, places, things, or concepts. Examples include "apple" which can be described by various adjectives.
Adjectives can specify quantity, quality, size, condition, or show possessive form, enhancing the noun's meaning. For example, "several books," "beautiful scenery." Whereas nouns can function as the subject or the object of a verb, and can be common, proper, concrete, abstract, countable, or uncountable, such as "books" or "information."
Adjectives are always used in conjunction with nouns and cannot stand alone in a sentence as the main subject or object. For example, "happy" must describe someone or something. In contrast, nouns can stand alone as the main subject or object of a sentence, such as in "Happiness is priceless."
In terms of form, adjectives can be graded for comparison, using forms like positive, comparative, and superlative (e.g., "small," "smaller," "smallest"). Whereas nouns may change form to express countability or possession but do not have comparative forms.
Adjectives require a noun to be complete and are placed directly before a noun or after linking verbs. For example, "The sky is blue." Whereas nouns can be preceded by determiners or adjectives and followed by phrases that modify them, such as in "The clarity of the water."
