There are many words between Scottish (GD) and Irish Gaelic (GA) which sound identical or are very similar, but have a slightly different meaning.
The thumbnail photo is of my Scottish Gaelic class at Oideas Gael Irish language school in Glencolumbkille, Donegal, Ireland.
Here are a few more false friends in addition to the ones in the video:
còisir (GD) – choir; cóisir (GA) – party
diofar (GD) – difference; deifir (GA) – hurry
buachaille (GD) – shepherd; buachaill (GA) – boy
bealach (GD) mountain pass; bealach (GA) – way
Last not least I loved to learn the Irish saying: Is beag an rud an cuidiú nuair a rinn an dreolín mún san fharraige! (It made little difference when the wren peed in the ocean)
