word-forming element meaning "many, much, multi-, one or more," from Greek polys "much" (plural polloi), from PIE root *pele- (1) "to fill," with derivatives referring to multitudinousness or abundance. Equivalent to Latin multi-, it is properly used in compounds only with words of Greek origin. In chemical names, usually indicating a compound with a large number of atoms or molecules of the same kind (such as polymer).
word-forming element meaning "one who is immersed in or driven by," mostly from French-derived words, ultimately from Greek -logos, -logon (see -logy). Now mostly superseded by -loger, -logist except in ideologue and a few others. As a combining element meaning "kind of discourse," it is from French -logue, from Greek -logos.
