"Do you like water?"
Translation:Dych chi'n hoffi dŵr?
What is the difference between "Dach" and "Dych"? Where did dach come from?
If you have android using Google keyboard you can add a Welsh keyboard in your settings, which will not only give you the letters you need with accents but it also has autocorrect in Welsh. I don't use apple so cant advise on those.
