"It is very bright today."
Translation:Tha i glè shoilleir an-diugh.
If it helps to remember the word soilleir, there are lots of pairs of opposites in Gaelic, with the 'good' word starting so- and the 'bad' word starting do-. Thus
And of course doilleir is easy to remember because it is like the English word dull. They seem to mean exactly the same thing although they are claimed to have completely different origins.
