Galwegian Gaelic
George Buchanan, himself a Gaelic speaker, writing in 1575, reported that Gaelic was still spoken in Galloway. In the middle of the century, 1563–1566, an anonymous English military investigator reported that the people of Carrick "for the most part specke erishe".

During the Middle Ages, the three Gaelic languages maintained a single standard for higher registers and poetry. This is sometimes misleadingly referred to as "Classical Irish" - despite the fact it was much in use in Scotland and presumably the Isle of Man. It is also known as Classical Gaelic.
