The name Kiai derives from kiai, meaning "no", due to a trend in the area to name languages based on their word for "no", used as a linguistic shibboleth. The language is called vara Kiai (from vara "speech, language"), i.e. 'the language that says kiai [for no]".
The same language has been named Fortsenal, based on the name of the village (locally Vorozenale) where the speakers live.[3]
