Ymddiheuriadau – er bod y mwyafrif o dudalennau'r wefan hon ar gael mewn Cymraeg a Saesneg, mae ambell dudalen nad yw ar gael yn Gymraeg. Y rheswm yw eu bod yn cael eu diweddaru'n rheolaidd, neu eu bod wrthi'n cael eu cyfieithu.

Apologies - although most pages on this site are available in both Welsh and English, a few are not available in Welsh. This is due to the fact that they are updated on a regular basis, or they are in the process of being translated.
