Chache or also chaché is a word used in several regions of Spain to name the older brother, uncle and/or adult friend of the family. Possibly the origin is in the Arabic 1588; 1602; 1610; 1602; (shaquic "brother") which was expanded in English to "brother of the father" or any familiar person who is an authority for children. Its feminine is 'chacha'. See chacho, cache, cache.
