I must be missing something basic but here's my question anyway.
I'm looking for the noun 'upheaval'. I got 'suaitheadh' in Focal.ie. In Ó Dónaill. suaitheadh has m. next to it so I presume it is both a noun and masculine. However, neither Ó Dónaill nor Focal.ie give its plural: both only give 'suaite', its genitive singular.
Here's my problem: I want to say "a lot of upheavals" and I know that after "a lán", "mórán" etc the noun changes into the genitive (gen. plural in this case) if the noun is lagiolra, e.g. 'a lán airgid'. It apparently does not change if the noun is treániolra, e.g. a lán fadhbanna. Given the above limitations, how do I work out whether the noun is lagiolra and what its genitive plural case is?
If I said "mórán suaite" would that mean "a lot of upheaval"?
