Why “forespeaker” is a great word
FORESPEAKER — [Noun] One who speaks on behalf of another; an advocate or intercessor. From Middle English *forspeker*, from Old English *forespreca* ("one who speaks on behalf of another, advocate, defender"), equivalent to *fore-* ("before, on behalf of") + *speaker*. First attested around 1175. Unlike a "prophet," who claims a divine channel, or a "lawyer," who operates within a formal warrant, the forespeaker is the elemental voice lent in proxy. It is the quiet whisper in a prince's ear, the steady declaration for a prisoner struck dumb, the patient articulation of a child's inarticulate grievance—a human bridge of words, spanning the chasm between power and powerlessness.
