Etymology: "Chunnered" is the past tense of "chunner," a Scottish and Northern English verb meaning to mutter or grumble under one's breath. The source confirms only that it is the simple past and past participle of "chunner," so the sense of the base verb is what matters here: a low, complaining, half-audible speech, the sort of quiet griping that is meant to be overheard without quite being addressed to anyone.

Synonyms: muttered, grumbled, murmured
