An isolating language is a type of language with a morpheme per word ratio close to one, and with no inflectional morphology whatsoever. In the extreme case, each word contains a single morpheme. Examples of widely spoken isolating languages are Yoruba[1] in West Africa and Vietnamese[2][3] (especially its colloquial register) in Southeast Asia.
A closely related concept is that of an analytic language, which uses unbound morphemes or syntactical constructions to indicate grammatical relationships. Isolating and analytic languages tend to overlap in linguistic scholarship.[2]
Isolating languages contrast with synthetic languages, also called inflectional languages, where words often consist of multiple morphemes.[4] That linguistic classification is subdivided into the classifications fusional, agglutinative, and polysynthetic, which are based on how the morphemes are combined.[5]
