"Mike, is your grandmother a professor?"
Translation:يا مايْك هَل جَدَّتَك أُسْتاذة؟
I forgot to put يا in front of مايْك and I got it right, but with the above sentence as "another correct solution". We've normally seen the name at the end of a sentence and I always include يا before the name. Is يا optional when the name is at the beginning of a sentence, or did I really get it wrong and DuoLingo was being kind to me?
