Word Origin and History for spill his guts

gut

n.

Old English guttas (plural) "bowels, entrails," related to geotan "to pour," from PIE *gheu- "pour" (see found (v.2)). Related to Middle Dutch gote, Dutch goot, German Gosse "gutter, drain," Middle English gote "channel, stream." Meaning "abdomen, belly" is from c.1400. 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"). Sense of "inside contents of anything" (usually plural) is from 1570s. To hate (someone's) guts is first attested 1918. The notion of the intestines as a seat of emotions is ancient (cf. bowel) and probably explains expressions such as gut reaction (1963), gut feeling (by 1970), and cf. guts. Gut check attested by 1976.

v.

"to remove the guts of" (fish, etc.), late 14c., from gut (n.); figurative use by 1680s. Related: Gutted; gutting.
