Word order with się
I'm confused about the order, mainly because it's different in Slovakia.
Are there some rules I can use to figure out where in sentence should się be used?
It is rather flexible. It can be used before or after a verb but not at the beginning of the sentence. Also, usually not at the end except short sentences when there is no other option.
What about questions?
And is it different for "wh-"(which have normal answers) and not "wh-" questions (which have yes/no answers)?
