"Is it a new thing?"
Translation:An rud nua é?
Because it requires the copula. You're classifying/identifying something, so bhfuil can't be used.
Gotcha. Then please report the hover hints as wrong so the contributors can fix them.
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?
If the gender of the object is known, then use the matching pronoun. If it’s unknown, then use an epicene é.
