This is the 38th most frequent Bulgarian word.
ли
The Bulgarian word "ли" is a particle used to form yes-no questions or to express doubt or emphasis.
Here, 'ли' is part of 'дали,' which introduces an indirect question meaning 'if' or 'whether.'
Чудя се дали той ще дойде.
I wonder if he will come.
The word 'ли' is used in this case to indicate a direct question, emphasizing 'ти' (you).
Ти ли го направи?
Did you do it?
In this context, 'ли' forms part of a polite question or request, placed after 'може' to inquire about possibility or permission.
