"She has to complain."

Translation: Rhaid iddi hi gwyno.

[GeoffBache]

Shouldn't there be a soft mutation after rhaid iddi hi? i.e. wyno?

[EllisVaughan]

There is, "Cwyno" is the base form of the verb. I'd recommend using "Ap geiriaduron" on IOS and Android which can tell you if a word has been mutated when you put it in.

[drowswell]

I was wondering where the mutation was and then realised it must be cwyno!

[DavidHalli8]

Would "Rhaid iddi hi gonan", be acceptable here? I picked up 'conan' from watching Pobol y Cwm.
