> politician, from "polis", city, and "-tician", "person"

I know you didn't really mean this, but polit/ic/ian -- "polit" is from polis, city; "ic" is a Greek adjective-forming element; and "an" or here "ian" is a Latin adjective-forming element. "Polit" is the only part of the word that bears any semantics (in the etymology). The Greek root for person would be "anthrop", which isn't present.

(The root for "man", an adult male, is "andr", which is why it's so hilarious to Italians that English speakers think Andrea is a girl's name.)
