The etymology of _Armagh_, in Ireland, is very simple. _Ard_, high,
great, noble, a purely Celtic root, found in many languages. Latin,
_Arduus_, high, &c. Welsh, _hardh_, fair, handsome, &c. _Magh_, a plain,
a level tract of land, a field. _Ardmugh_, the great plain. Others
derive it from _Eamhuin-magh_, from the regal residence of the kings of
Ulster, that stood in its vicinity; but the former is considered by
those best capable of judging as the most correct. The original name was
_Druim-sailech_, "the hill of sallows," which was changed to
_Ard-sailech_, "the height of sallows," and then again to _Ardmagh_.
Although now spelt _Armagh_, it was formerly more correctly written
_Ardmagh_, which is undoubtedly the proper way.
