I thought saor was free, not cheap. Can it be used for either?
Saor means cheap in cost or free in the sense of liberty. If you want to say something is free of charge you would usually say 'saor an-asgaidh' or just 'an-asgaidh'
Tapadh leibh! Tha mi a' tuigsinn.
That's an important distinction. 'Saor Alba' disnae mean 'cheap Scotland' ;-). The dual use of 'saor' has always tickled me, and must lead to a few punning jokes in Gàidhlig :o)
