"Yes, I want to pay."
Translation:Ydw, dw i eisiau talu.
Up until this unit we have introduced 'Ydw' and Nac ydw'
In Welsh we affirm or negate the question, so 'Ydw' = Yes I am/Yes I do and 'Nac ydw' = No I am not, No I do not.
This is why we have different ways of responding positively or negatively.
This unit introduces 'Cei' = 'Yes, you may' in response to the very common and useful expression in Welsh 'Ga i' = May I have
Therefore the positive and negative response always depends on the question being asked.
The various forms are introduced as the course progresses.
But for a learner who is using the language it's quite easy to use 'iawn' (OK) as a positive reponse and 'Na' as a negative one.
