What does the French word wslij mean?

The word "wslij" does not exist in French. It's possible you've made a typo.

Could you double-check the spelling? Maybe you meant something like:

* "s'il vous plaît" which means "please"

* "il s'agit" which means "it is a question of" or "it concerns"

* "il y a" which means "there is" or "there are"

Please provide more context if you can, and I'll be happy to help you find the correct word.
