I will write here everything I learn in Kuman. There will be the same rule as in Karavinka's Turkish thread: no hints or explanations.
Here is what I have learned so far:
erepa - go
eriyawo - come
bitero - stop
E wa? - How are you?
Na ... - My name is ...
Kipainga ai de? - Where do you live?
Na Ukraine suna milge. - I live in Ukraine.
Waii wo. - Thank you.
Ena. - Goodbye.
Eropnge. - I go home.
igi - home, house
nil - water
