Comparative and Superlative Forms of Adjectives

Comparative and Superlative Forms of Adjectives Edit

Understand the comparative and superlative forms of adjectives to describe nouns effectively, show differences between two entities, or identify extremes among many objects.

Adjectives work either as noun modifiers or as complements (that completes) of a sentence.

What Are the Three Forms of Adjectives?

Adjectives have three distinct forms depending on whether you are describing a single item, comparing two items, or showing the highest degree among multiple items.
