Etymology

From Middle English clam (“pincers, vice, clamp”), from Old English clam (“bond, fetter, grip, grasp”), from Proto-West Germanic *klammjan (“press, squeeze together”). The sense “dollar” may allude to wampum. The sense "Scientologist" alludes to the Scientologist belief that human thetans (souls) previously inhabited clams.

From Middle English clammen, clemen (“to smear, bedaub”), from Old English clǣman (“to smear, bedaub”). Cognate with German klamm (“clammy”). See also clammy (“damp, cold and sticky”) and clem (“to adhere, stick, plug (a hole)”).
