Saraveca is an extinct Arawakan language once spoken in Bolivia by the Sarave.

It is said[1][2] to be the only language with a numeral system based exclusively on five, although quinary systems exist.

To some extent this is also an areal feature of other South American languages; many form their numbers 6–9 as "five + one", "five + two" and so on.

By 1962, most people has switched to Chiquitano.
