gutyoudaoicibaDictYouDict[gut 词源字典]
gut: [OE] 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’ [17]. The use of the plural guts for ‘vigour’ or ‘courage’ dates from the late 19th century.

Meaning "narrow passage in a body of water" is from 1530s. Meaning "easy college course" is student slang from 1916, probably from obsolete slang sense of "feast" (the connecting notion is "something that one can eat up").
