Hi Znize
Kajtek said almost everything, I can only add a few examples because I see you are very interested in the subject of your nick

Yes, your nick is similar to the verb "zniżę" but I hadn't thought that if you wouldn't have asked it. This is for polonymes, without accents this similarity becomes smaller
"zniżę" is the first person sing. of the verb "zniżyć". And zniżyć is a finite of "zniżać" so quite complicate
zniżać (in in dictionary) is also
to descend (f.e. fly); to lower (which kaj said) for example with voice or price, to lessen;
in Polish this verb is the most often used with "się" so "zniżać się".
There are two cases:
To descend - also with plane for example and the second, more used:
to condescend (in the case f.e.: to condescend to the children)
