Middle Irish Wikipedia
Middle Irish (sometimes called Middle Gaelic) is the Goidelic language which was spoken in Ireland, most of Scotland and the Isle of Man from the 10th to 12th centuries; it is therefore a contemporary of late Old English and early Middle English. The modern Goidelic languages—Irish, Scottish and Manx—are all descendants of Middle Irish.
The Lebor Bretnach, the "Irish Nennius", survives only from manuscripts preserved in Ireland; however, Thomas Owen Clancy has argued that it was written in Scotland, at the monastery in Abernethy.
