Buckley -- in a mostly English-speaking part of Wales -- had in the fairly recent past, its own very distinctive English dialect (now mostly "extinct") -- Wiki's description is to the effect of, full of colloquialisms peculiar to it, and often unintelligible to outsiders. In the accompanying list of such colloquialisms are "A lick and a promise" = a quick wash; and, to "chunner" = grumble / mumble / complain. In my childhood, my late parents frequently used both of those. Possibility seen, of their use in our family originating from my father; whose family in his youth dwelt -- though they were, solidly, ethnically English -- in Penyffordd, Flintshire: a couple of miles south-east of Buckley.
