must be someone from the north asked someone from the south how to say "now", but the reply was in a mirror or something.
I don't understand why i am wrong using nawr? Why rwan?
Are there any other colloquialisms for 'now'?
There are several words and expressions for 'now', not really colloquialisms, some with slightly different shades of meaning. nawr and rŵan are both in common use for a simple 'now' and you will meet both in the Welsh media.
