"Do you like Fishguard?"
Translation:Dych chi'n hoffi Abergwaun?
Yes, there is a very good reason at the beginning of the course.
With spoken Welsh 'chi' has the same form 'dych chi' in the positive, negative and question.
Whereas 'ti' is different in all forms.
Since the verb to be in Welsh is so irregular 'chi' is easier to grasp initially.
