"Is it a new thing?"
Translation:An rud nua é?
I just saw at nualeargais.ie that the "object form" and the "copular form" are almost always identical.
Why? Has it something to do with the accusative case? If I say "A is classified as a B", does that make B an accusative object?
If so, I would guess that a distinct accusative case vanished for Irish nouns, but remains for pronouns...
And if that's right, why the exception for the 2nd prs. sing.: object thú, but copular tú?
