fusional

This term is a specialized linguistic descriptor used to categorize languages based on their morphological structure. It describes a system where a single inflectional affix carries multiple pieces of grammatical information, making it impossible to isolate a specific morpheme for a single category like "plural" or "dative."

In contrast to agglutinative languages, where each morpheme typically has one distinct meaning and boundaries between them are clear, fusional languages blend these markers. This creates a high degree of synthesis and often results in complex paradigms where one ending serves several functions simultaneously.
