In French, comparative phrases are often used to express a comparison between two or more items. They can be adjective comparatives, adverb comparatives, or noun comparatives and are formed by using “plus” (more), “moins” (less), or “aussi” (as) before the adjective, adverb, or noun being compared, and “que” (than) before the term being compared to. Understanding and applying comparative structures correctly is an important part of mastering French grammar.
