A language with no bound morphology.
Isolating languages are languages that have no bound morphology, meaning that every word is a single morpheme. An ideal isolating language would have a one-to-one correspondence between morphemes and words. The usual example of an extreme isolating language is Vietnamese but a number of other East Asian languages are also highly isolating. Another almost completely isolating language is the Austronesian language Keo, spoken on Flores in Indonesia.
