Is gaelic still spoken?
History of Scottish Gaelic
All surviving dialects are Highland and/or Hebridean dialects. Dialects of Lowland Gaelic have become defunct since the demise of Galwegian Gaelic, originally spoken in Galloway, which seems to have been the last Lowland dialect and which survived into the Modern Period. By the 18th century Lowland Gaelic had been largely replaced by Lowland Scots across much of Lowland Scotland. According to a reference in "The Carrick Covenanters " by James Crichton, the last place in the Lowlands where Scottish Gaelic was still spoken was the village of Barr in Carrick: only a few miles inland to the east of Girvan, but at one time very isolated. Crichton gives neither date nor details.
Caithness
As previously indicated, the language mix or boundary changed over time, but the "New Statistical Record" in 1841 says: "On the eastern side of [the Burn of East Clyth] scarcely a word of Gaelic was either spoken or understood, and on the west side, English suffered the same fate". Other sources state:According to the 2011 Scotland Census, 282 (1.1%) residents of Caithness age three and over can speak Gaelic while 466 (1.8%) have some facility with the language. The percentage figures are almost exactly the same as for all of Scotland (1.1% and 1.7%, respectively). Nearly half of all Gaelic speakers in the county live in Thurso civil parish. The town of Thurso hosts the only Gaelic Medium Primary School unit in all of Caithness (see Language in Thurso).
