Translation:Faset ti'n ceisio bwyta hufen iâ a letys?
Lettuce is gwylaeth?
Very unusual nowadays.
Are you trying to suggest that as an alternate translation?
Yes i think so. It sounds Welsh instead of distinctly English.
Yes, that's another version. It's also spelled as "letus": http://geiriadur.ac.uk/gpc/gpc.html?letys
