Why does it not start with "maen" since "ceri lingo a dewi lingo" is a specific way of saying "nhw" which calls for "maen"?
Only the word nhw calls for maen.
If you have a plural noun, or multiple nouns, as the subject, then you use mae just like with a singular noun subject.
Why does the 'yn' not contract here? It does in the sentence 'Mae
Ceri Lingo'n bert' tested earlier.
It should. This will be fixed shortly.
wow, my question answered before I'd even finished that lesson! Diolch yn fawr, seren dych chi. (Bet that's not right....)
