The Kru languages belong to the Niger–Congo language family and are spoken by the Kru people from the southeast of Liberia to the east of Ivory Coast. The term "Kru" is of unknown origin. According to Westermann (1952) it was used by Europeans to denote a number of tribes speaking related dialects. Marchese (1989) notes the fact that many of these peoples were recruited as “crew” by European seafarers; “the homonymy with crew is obvious, and is at least one source of the confusion among Europeans that there was a Kru/crew tribe”
