Example sentences

Rwy'n cofio bod mewn cyfarfod bord gron gyda Hefin tua dwy flynedd yn ôl gyda phreswylydd a oedd wedi cael ei ymosod yn drasig gan gi, a hwylusodd y preswylydd hwnnw i allu siarad amdano.

I remember being in a round-table meeting with Hefin around two years ago with a resident who had been tragically attacked by a dog, and he facilitated that resident in being able to talk about it.
