Denbighshire is a county in the north-east of Wales. It borders the Irish Sea to the north, Flintshire to the east, Wrexham to the southeast, Powys to the south, and Gwynedd and Conwy to the west. Rhyl is the largest town, and Ruthin is the administrative centre. Its borders differ from the historic county of the same name.

Welsh is a Celtic language of the Brittonic subgroup that is native to the Welsh people. Welsh is spoken natively in Wales, by some in England, and in Y Wladfa.
