Desinence refers to the ending of a word, particularly in language. There are several different synonyms that can be used to describe this concept, including inflection, termination, suffix, and ending. Inflection specifically refers to changes in the form of a word to indicate tense, gender, and other grammatical variations. Termination and suffix are similar to desinence in that they refer to the final part of a word or phrase. An ending is also a term that describes the final letters or syllables of a word. These different synonyms help to describe the many different aspects of language and the way that words can be constructed and modified.
