The Aimoré, Botocudoan or Borum languages, now sometimes known as Krenakan after the last one remaining, are a branch of the Macro-Jê languages – spoken mainly in Brazil – including moribund Krenak and extinct languages such as Guerén and Nakrehé. Loukotka (1968)^[1] considered them dialects of a single language, but more recent treatments (Campbell 1997, Campbell 2012)^[2] describe at least some of them as separate languages.

A fair amount of lexical data was collected before the majority of languages became extinct.
