Radio Cymru new listener

Cwestiwn? Dwi’n newydd dechrau gwrando am radio Cymru heddiw. Yn cyntaf Siân Cothi a wedyn O’r Bae. Nawr, pam deallais i mwy o O’r Bae na Siân Cothi? Was it just that my ears/ brain had started to tune in or is it about dialect?

I think probably a bit of both, but also maybe that Siân Cothi’s speech was much more colloquial?
