agglutinative

This term is primarily used within the specialized register of linguistics to describe a specific morphological process. It describes a "gluing" mechanism where prefixes and suffixes are appended to a root word without merging or altering the sounds of the original components, creating long, complex word-chains that function like entire sentences in other languages.

It stands in direct contrast to fusional languages, such as Latin or Spanish, where a single ending might represent multiple grammatical categories (like gender, number, and case) simultaneously and often blends into the root. Because it is a technical descriptor, it is rarely encountered in casual conversation and is almost exclusively found in academic or descriptive linguistic contexts.
