Fòram na Gàidhlig

Sorry if this is the wrong place, I'm new to this site and a beginner. Feel free to move this thread if it's in the wrong place.

Bha mi chunnaich na poileasmain an-diugh. Bha iad air an rathad.


I feel like I did ...

Thank you, I appreciate it!

I'm an American student who's really interested in linguistics. I speak English, Italian, and am learning Gàidhlig in my spare time. To be honest, I hadn't really thought much about Gaelic until I listened to Julie Fowlis, and wanted to know what she was saying. I'm pretty much an absolute beginner ...
