Translation:Dych chi'n hoffi'r het wen?
This is one of those cases where the ..'r... is by itself instead of being with hoffi. From what I'm being told this is wrong and should be ...hoffi'r... And should be reported so I did, but I am still unsure.
Said I had a typo when I spelled white as gwen. Showed it as wen.
Yes :) het is feminine, and feminine nouns cause a following adjective to undergo soft mutation -- under which g disappears.
