what is the difference between w and we (and also z and ze)? Does it depend on the case?
"latać" (generally, habitually), "lecieć" (right now)
So basically, "latać" = to fly, and "lecieć" = to be flying.
Please allow me to correct you, as you wrote it that way at least twice: it's dziękuję :)
Using "en" instead of "ę" is considered a very serious mistake.
dziękuję bardzo, I used to write it like that bcs I don't have these letters in my PC. thanks
In that case it's better to just use normal e - although obviously it's best to find a way to use Polish letters :) For example if you use an English keyboard, you can use a Polish one instad - it has all you need for English + all you need for Polish.
Using en instead of ę is something that uneducated natives do sometimes.
