Which area of grammar deals specifically with the formation of words?

Morphology is the area of grammar that is concerned with the structure and formation of words. It involves the study of morphemes, which are the smallest units of meaning in a language. Morphology examines how these morphemes combine to create new words and how they affect the meanings of those words. This includes the analysis of prefixes, suffixes, roots, and how they collaborate to form complex words. Understanding morphology is fundamental in analyzing word formation patterns and how they contribute to the richness of language, making it a critical aspect of grammar in the context of linguistics and language education.
