Persian Morphology
Word Formation and Derivation

Persian prefix هم (ham-) is cognate with Old English sama and Greek homos (same). The Greek prefix is found in English words that begin with homo-. Words that derive from هم are adjective and mean "of the same", "having the same", "sharing the same". Its function is similar to English homo- (homograph), co- (co-worker), fellow- (fellow workers) and -mate (workmate). This prefix is very productive and helps you guess the meaning of many Persian words.
