Done it (kind of, I think). It took a couple of minutes, but I did get confused over āthat I needā - I went with something like āMae hyn 'na 'r peth dw i angenā and then came back here to see @aranās reference to āboā fi angenā. So now Iām trying to figure out what kind of structure was intended - something like āWnaeth o dweud wrtha fi boā fi angen mynd iār gwaithā, or what?
