How do you say thank you in Quechua?

Quechua varies a lot across dialects, and there are a few different ways to say "thank you" in different situations. Here are two ways to say "thank you" in the Cuzco dialect of Peru:

Añaychayki(ah-nyai-chai-kee)

Sulpayki(sool-pai-kee)

The "ki" at the end of the Words means "you," so you can also just say "sulpay" or "añaychay" which are more informal, like "thanks."
