Latin and English (indogermanic/indoeuropean) are members of a completely different family of languages than Hebrew (semitic). Suffix has nothing to do with Hebrew, Janus explained it correctly. Imperium also has nothing to do with Hebrew. It is Latin and derives from impero, -as, -are which means to order or to command and which itself consists of im("in") + parare (to prepare or to order). "Syfer" in Afrikaans (also indogerm./indoeurop.) or "Ziffer" in German are loanwords (via Italian) from Arabic "sifr" which itself seems to be a loanword or adaption from Middle Greek or Old Indic, but I'd have to look that up.
