What is "kikar"

n. A tree native to South Asia, (taxlink Vachellia nilotica subsp. indica subspecies noshow=1), formerly (taxlink Acacia nilotica subsp. indica subspecies noshow=1).

KiKAR is, or was, a Swahili pidgin spoken among the King's African Rifles (KAR) of British colonial East Africa (Kenya, Uganda, Malawi). Although there were, by design, no native Swahili speakers among the KAR, Swahili still functioned as the lingua franca, and a simplified version of it served as a military jargon and pidgin for the troops.

It is not clear if KiKAR is still spoken. Maho (2009) does not list it as extinct.
