abogado (Noun) "lawyer," "advocate," "counsel"

13th cent. From Latin advocatus "aide," "advocate," "witness." From advocare "to advocate" (see abogar).

Historically, la abogada typically meant "interceding saint" and when used for "lawyer" was an insult, as the profession of advocate was exclusive to men prior to the 1960s.
