↑The name is a composite of two distinct Greek roots — Protheo- (προθέω), meaning "to run ahead," "to rush forward," or "to urge on" and -enor (-ήνωρ), a suffix derived from anēr (ἀνήρ), meaning "man" or "warrior." In ancient Greek compound names, it often denotes characteristics of masculinity, leadership, or bravery.
