Origin & History of “gut”

Gut probably comes ultimately from prehistoric Indo-European *gh(e)u- ‘pour’ (source also of English foundry, funnel, fusion, etc), and presumably has the underlying meaning ‘tube through which digested food flows’. From the same source came Greek khūmós ‘animal or plant juice’, from which English got the technical term chyme ‘mass of semidigested food in the stomach’ (17th c.).

The use of the plural guts for ‘vigour’ or ‘courage’ dates from the late 19th century.
