Macro-Jê (also spelled Macro-Gê) is a medium-sized language stock in South America, mostly in Brazil but also in small parts of Argentina, Paraguay and Bolivia. It is centered on the Jê language family, with all other branches currently being single languages due to recent extinctions. The family was first proposed in 1926, and has undergone moderate modifications since then. Kaufman (1990) finds the proposal "probable".
