"Dw i'n mynd i Aberdaron rŵan."

Translation: I am going to Aberdaron now.

[AnCatDubh]

So when is this word used instead of nawr?

[crepuscularr]

From what I remember from the comments section of another sentence, "nawr" tends to be used in South Wales and "rŵan" in North Wales. So they're pretty much interchangeable.

[YGymraes]

Why is only North Walian Welsh available?
