Word Origin & History

leech
"bloodsucking aquatic worm," from O.E. læce (Kentish lyce), of unknown origin (with a cognate in M.Du. lake). Commonly regarded as a transf. use of leech (2), but the O.E. forms suggest a distinct word, which has been assimilated to leech (2) by folk etymology. Figuratively applied to human parasites since 1784.

leech
obsolete for "physician," from O.E. læce, from O.Dan. læke, from P.Gmc. *lælijaz "healer, physician" (cf. O.N. læknir, O.H.G. lahhi, Goth. lekeis "physician"), lit. "one who counsels," perhaps connected with a root found in Celt. (cf. Ir. liaig "charmer, exorcist, physician") and/or Slavic (cf. Serbo-Croatian lijekar), with an original sense of "speak, talk, whisper, conjurer." The form and sense merged with leech (1) in M.E. by folk etymology. In 17c., leech usually was applied only to veterinary practitioners. The third finger of the hand, in O.E., was læcfinger, translating L. digitus medicus, Gk. daktylus iatrikos, supposedly because a vein from that finger stretches straight to the heart.
