language with a very low morpheme per word ratio
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 in West Africa and Vietnamese (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.
