Middle Irish, sometimes called Middle Gaelic (Irish: An Mheán-Ghaeilge), is the Goidelic which was spoken in Ireland, most of Scotland and the Isle of Man from circa 900–1200 AD; it is therefore a contemporary of late Old English and early Middle English. The modern Goidelic languages—Irish, Scottish Gaelic 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.
