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?"
It doesn't mean "is there X at Y?". It means "Does Y have X?". Some English speakers like to translate that ag as "at", but Irish speakers don't, just as English speakers don't think that the "have" in "I have to do something" has something to do with possession.
So...just asking....ceithre is always pronounced "ken" or us that a specific dialect?... ceithre chat here sounds like "ken hut"...not complaining, just curious and good we are exposed to actual pronunciation.
