the.com/peevishness

Irritation too petty to be anger, too persistent to ignore.

means A cranky, easily-irritated temperament that snaps or sulks over small annoyances.

from From 'peevish,' which shows up in Middle English (notably in Chaucer's time) meaning foolish, spiteful, or perverse — though its own origin before that is murky, possibly linked to Latin 'perversus' (turned the wrong way) or simply coined as an echo of that fretful, contrary sound. The '-ness' was bolted on later to turn the mood into a noun — the state of being perpetually, pettily put out.
