"Before you go, you have to finish."
Translation:Cyn i chi fynd, rhaid i chi orffen.
I don't understand why the proper structure for ti doesn't softly mutate ti
Cyn i di fynd, rhaid i di orffen. (wrong) Cyn i ti fynd, rhaid i ti orffen. (right)
i causes a soft mutation, unless it's the pronoun. I must be wrong in some way- What is the proper explanation?
EDIT: On a side note, Duo marks it as a type, not per se as a wrong answer.
