gutsy

the word 'gutsy' is a modern english formation that builds upon the long-established metaphorical use of 'guts'. the noun 'guts', originally referring literally to the internal organs, has been used since the 16th century to signify courage and fortitude, likely from the idea of the bowels being the seat of strong emotions. the productive adjective-forming suffix '-y', of old english origin, is appended to create a descriptive term meaning 'full of guts' in this metaphorical sense. thus, 'gutsy' directly translates the abstract quality of bravery into a tangible, visceral image rooted in the body.

Structure: guts (noun) + y (adjective-forming suffix) guts (middle english, from old english guttas, meaning 'bowels, entrails', used metaphorically for courage or spirit); y (old english suffix -ig, used to form adjectives meaning 'having the quality of').
