What's the deal with 'ceithre'? Why isn't it 'ceathair'? Should I get off my phone and turn on my computer 'cos maybe there's notes about this?
It just changes when counting things. Pretty much all there is to it. That's probably why this sentence exists, since two also changes.
Is the plural of apcat and dog implied because there is a number in front of them or should it be cait agus madraí?
They need to change the definitions under "an bjfuil". The translations they give are only variations of "are you" I could imagine stretching that to "are there" like other lessons, but the word bank is all that stopped me typing "are you four cats or two dogs?"
