"What is Dewi Lingo like?"
Translation:Sut un ydy Dewi Lingo?
No, this is a specific phrase that we use in Welsh that you do not translate directly. I guess you could say "Beth ydy Dewi Lingo fel" but it sounds really bad to the ear. EDIT: Just looked at this again after one year and I wanna get rid of the last sentence, you'd never use "Beth" in this sort of sentence.
