See-Zar is just the way english speaken persons speak it when they have no Idea what the original language sounded like.
It still happens today, with people not used or not knowing to speaking a language will automatically try to read it out loud in a way familiar to them.
example?
take a few capitals of the world: Paris is pronounced Pah-ree in french, but Par-is in english, Berlin is Ber-leen in German, but Burr-lynn in English. Amsterdam is pronounced Ahm-stur-dahm in Dutch, and we all know what it sounds like in English (can't figure out a way to write it that comes even remotely close to what it sounds like)
