One of the hints is "A bheil càr ùr agad a sheanair" but then states I am incorrect if I use it, why?
Sorry, I've fixed that :)
"A bheil càr ùr agad a sheanair" is still being marked as wrong, why?
Speech is becoming less formal these days so to what extent would such a slip be frowned upon?
If we were addressing "father", how would we do that? Not "a' athair"?
When the following word starts with a vowel, you don't use the "a" particle.
