Knowra Grammaticalization Grammaticalization Grammaticalization is the historical development by which lexical items or constructions acquire grammatical functions, often becoming more bound and less semantically specific over time.
Semantic bleaching : The weakening or loss of a word’s specific lexical meaning while its grammatical function persists. Loss of lexical meaning often accompanies a form’s shift toward grammatical use.
Lexical category : A class of words with lexical content, such as nouns, verbs, and adjectives. Grammaticalization often begins with a form belonging to a lexical category.
Be going to : An English construction expressing future or prospective meaning, historically derived from a motion construction. Its path from movement toward a goal to future marking is a well-known case.
Lexicalization : The development of a linguistic expression into a conventional lexical unit, often with reduced internal compositionality. It is often treated as a partly opposite direction of change from grammaticalization.
Phonological reduction : The shortening or weakening of a speech form’s pronunciation. Frequent grammatical forms often lose phonetic substance as they become more predictable.
Grammatical category : A linguistic distinction expressed through features such as tense, number, case, or aspect. The developing form acquires a role in expressing grammatical distinctions.
Have to : An English construction that expresses obligation or necessity. It developed from a possession construction into a marker of obligation.
Degrammaticalization : A change in which a grammatical form acquires more lexical or independent properties. It describes the less common reverse direction, challenging one-way accounts of change.
Cliticization : The development of a word into a clitic, a form prosodically dependent on a neighboring word. It captures an intermediate stage between independent words and bound grammatical forms.
Morpheme : The smallest linguistic unit that carries meaning or grammatical function. A grammaticalized form may become a bound morpheme.
