Why is oes afal gynnoch chi? Not also an acceptable answer?
Because there was a mistake in the database, now corrected. Thank you!
Have a lingot as a bounty for the error.
I was marked wrong for 'Oes afal 'da chi?
'da is an informal spoken form of gyda, and it is probably not in the database as an answer. Try answering with ...gyda chi when it next comes up.
