"Where is your money?"
Translation:Cá bhfuil do chuid airgid?
I'm doing this lesson by mobile, and I can very rarely access the links. Any idea why, or could you possibly provide the name of the site as well? I can click on links that are bare links, at least sometimes. Unfortunately, this seems to happen with most of your links. Thanks for all you do!
That's odd, but I don't use the app. Perhaps try accessing Duolingo via the browser and following it from there?
If not, the site is Gramadach na Gaeilge. If you google it, you'll find it pretty easily. The section here is under 'Possessive Adjectives' where it talks about 'the usage of cuid'
