Translation:Dw i eisiau cot newydd.
What does 'moyn' mean? as this hasn't really been covered...
I've seen it on Wiktionary, meaning "want", in the Welsh translation of "I want to know", a phrase used to help clarify a request for information.
I'm guessing that Person A said "I want to go to the store" and Person B said "Why?"
Is it cot or côt?
I remember someone saying that both are right. (color/colour)
Why do you regard "mae eisiau cot newydd arno i" as wrong?
That is not a pattern generally used in colloquial Welsh, and it is not taught on introductory courses.
