Senedd Cymru yw'r corff sy'n cael ei ethol yn ddemocrataidd i gynrychioli buddiannau Cymru, i phobl, i ddeddfu ar gyfer Cymru, i gytuno ar drethi yng Nghymru, ac i ddwyn Llywodraeth Cymru i gyfrif.

The Welsh Parliament is the democratically elected body that represents the interests of Wales and its people, makes laws for Wales, agrees Welsh taxes and holds the Welsh Government to account.
