Grammatilised

Grammaticalised, also spelled grammaticalised in British English, is a linguistic term used to describe a form that has undergone grammaticalisation. Grammaticalisation is the process by which a lexical item or construction shifts to serve a grammatical function, becoming a marker of tense, aspect, mood, evidentiality, polarity, or other grammatical meanings. A grammaticalised form typically exhibits a reduced or weakened lexical meaning and an increased role as a grammatical marker, often accompanied by phonological reduction or cliticization.

In usage, grammaticalised denotes the result of this diachronic change. The American English equivalent is grammaticalized. The term is employed in historical and sociolinguistic descriptions to discuss how languages transform words or constructions over time. It can apply to elements such as future markers, auxiliary verbs, or other function words that originate from more concrete lexical material but acquire a stable grammatical function in a language.

As a descriptive label, grammaticalised does not correspond to a single word class. Instead, it signals that a form has shifted its primary purpose from lexical content to grammatical function within a specific linguistic system. The concept is central to studies of language change, typology, and the evolution of tense, aspect, and mood marking across languages.
