McCoy and Galloglass are both Anglicisations of terms from what language?
McCoy (surname) McCoy is a common surname of Scottish origin in the lands of Kintyre and then Irish (Gallowglass) origin. It is an Anglicisation of its Irish Gaelic form Mac Aodha, meaning "son of Aodh" (an old word for "Fire", a Celtic deity). It is particularly found in Ulster (Counties Antrim, Armagh and Monaghan) where many settled around the 13th century, having been Gallowglasses, and also in counties Limerick and Cork. Aoidh and Mac Aoigh were sometimes Anglicised as Hugh and McHugh.
Béarlachas Béarlachas (] ) is Irish for words and phrases used in Irish that are influenced by or stem from the English language. The term comes from "Béarla ", the Irish word for the English language, and refers to both simple anglicisms and interlanguage forms. It is a result of bilingualism within a society where there is a dominant, superstrate language (in this case, English) and a minority substrate language with few or no monolingual speakers and a perceived "lesser" status (in this case, Irish).
