In English when you give up on something or admit that you’re defeated, you might say that you’re throwing in the towel or the sponge, a phrase that comes from boxing. In Welsh you put the fiddle on the roof: rhoi’r ffidil ar y tô. I like the image this conjures up.

Other Welsh idioms I like include siarad fel melin bupur = to talk like a pepper mill, i.e. to talk non-stop, mae hi’n bwrw cyllyll a ffyrc = it’s raining knives and forks, i.e. it’s raining heavily, and mae’r olwyn wedi troi = the wheel has turned, i.e. times have changed.
