Translation:Мама та тато.
What is the difference between "та" and "і"?
I used мама й тато. Its correct! So whats the difference?
They all mean the same thing and thus can be used interchangeably. However, we use different words to make the sentence sound more melodically. See the wonderful explanation by sagitta145 in this thread: https://www.duolingo.com/comment/9266471
Does Та,й,і all mean and?
Yes, this is correct, they all mean "and".
I used "batiko", why is it wrong? Thank you
Please consider switching to the Cyrillic. It will save you a lot of trouble.
