Key Differences

An adjective is a part of speech that describes, identifies, or quantifies a noun or pronoun, adding specificity and detail. For example, in "The green car," "green" is an adjective describing the car. On the other hand, a substantive is a term used in grammatical discussion to denote a noun or any word or word group functioning like a noun. For instance, "car" in "The car is fast" serves as a substantive because it acts as the subject.
Adjectives can take different forms to indicate comparative and superlative degrees, such as "small," "smaller," "smallest." These forms help compare one noun to others in terms of the adjective’s quality. Substantives do not change form based on comparison but may change to show pluralization or possession, such as "cars" or "car's."
While adjectives are used primarily to modify and provide more information about a noun, substantives themselves can perform the roles of subjects, objects, or complement within a sentence. For example, "Joy is contagious," where "Joy" functions as a substantive.
Adjectives are always dependent on a noun for their function and cannot stand alone without a noun to modify. In contrast, substantives can stand alone as they are nouns or act in the capacity of nouns within a sentence structure.
In terms of placement, adjectives usually precede the noun they modify in English, as in "beautiful scenery." However, substantives follow typical noun syntax, appearing in subject, object, or possessive positions within a sentence, such as in "The scenery is beautiful."
