"Dych chi'n denau."
Translation:You are slim.
The instructions for this lesson said that adjectives only have a soft mutation after "Mae hi'n" and "Mae e'n". Should this be "Dych chi'n tenau" or do adjectives lenite after "Dych chi'n" as well?
If you wanted to use two adjectives would it be Dych chi'n denau a bert or Dych chi'n denau a pert ? That is, does the soft mutation apply to all the adjectives or just the first ?
