'Chan eil i briste' - when would we use 'chan eil i' as opposed to 'chan eil e' to mean it is not? Is 'briste' feminine and that's why we have this construction?
It's because làmh is feminine. The concept is rare in English, but ships are always "she".
I was marked down for writing 'My hand is sore but it's not broken'.
Silly rejections like that are very tiresome, and misleading for non-native English speakers.
This is a very new course. It takes time (and a lot of effort) for all the variations to go into the answers.
