Jalaa, also known as Cèntûm, Centúúm or Cen Tuum, is an extinct language of northeastern Nigeria, of uncertain origins, apparently a language isolate. The Jalabe speak the Bwilim dialect of the Dikaka language. It is possible that some remembered words have been retained for religious ceremonies, but in 1992 only a few elders remember words that their parents had used, and by 2010 there may not even remain any such rememberers.
An unclassified language is a language whose genetic affiliation to other languages has not been established. Languages can be unclassified for a variety of reasons, mostly due to a lack of reliable data but sometimes due to the confounding influence of language contact, if different layers of its vocabulary or morphology point in different directions and it is not clear which represents the ancestral form of the language. Some poorly known extinct languages, such as Gutian and Cacán, are simply unclassifiable, and it is unlikely the situation will ever change.
