How do you say yes in Irish?

Answer 1

There are no Irish words for yes or no.

But you can reply in a positive way that is taken as a yes answer, or a negative way for a no answer, examples:

to reply to a question such as, Do you understand?

In Irish that would be: an dtuigeanntú?

your reply would be, understand In Iris that would be: tuigim

for a negative responce to the same question, I don't understand.

In Irish it's: ní thuigim

A response will differ depending on what was asked.

If you are asked Are you going? in Irish your answer could be níl
