"The computer is in a school."
Translation:Tha an coimpiutair ann an sgoil.
an can mean lots of things depending on context:
- the – the definite article, the first an in this sentence,
- in – most often doubled as ann an (as here the second one), but can stand on its own too, eg. an Glaschu (or ann an Glaschu) in Glasgow,
- their – eg. an athair would mean their father (vs. an t-athair the father in nominative; but it also could mean the father in dative, eg. ris an athair with the father or with their father – context disambiguates),
- does?, is?, etc. – the interrogative particle, eg. in an toil leat e? do you like it?, an ith thu e? will you eat it?
- (with, on, at, to…) which, whom, etc. – the indirect relative particle after a preposition, eg. am fear ris an robh mi a’ bruidhinn the man to whom I was speaking
After ann, though, it can only mean in, ie. ann an always just mean in. And when there is the definite article – the the – after in, then it changes to anns + the article, eg. anns an sgoil in the school, anns a’ bhogsa in the box, anns na h-eaglaisean in the churches.
