Literary notes about grouch (AI summary)
In literature the term "grouch" functions both as a label for a consistently ill-tempered character and as a metaphor for a pervasive state of discontent. Writers may use it to evoke an inner irritability, as when a character is said to harbor "a grouch on the inside" [1], or to capture the light-hearted ribbing among acquaintances, as in the teasing call of "you old grouch" [2] or the wry remark about harboring a grouch [3]. At times it even becomes emblematic of social commentary—linking a curmudgeonly disposition with larger thematic conflicts, where a grouch might be as much an attitude as it is a personal trait [4][5][6].
