Translation:Chwaraea i griced yfory.
How about “dw i am chwarae criced yfory”?
That's a good suggestion, added now, thanks.
Does that mean "i want to play cricket tomorrow"?
Yes, that's another translation of 'dw i am'
what about 'mi fydda i--'?
That is a dialect form that we do not routinely cover in the course.
