来自古英语laece,巫师，巫医，医生，来自PIE*leg,读，词源同legible,lecture.引申词义念咒，召唤鬼神，后词义过渡到医生。因从古希腊时代，水蛭就作为重要的治病工具用于给病人吸血，放血，该词就逐渐引申水蛭，蚂蝗词义。比较invoke,incantation.

leech (n.1)

"bloodsucking aquatic worm," from Old English læce (Kentish lyce), of unknown origin (with a cognate in Middle Dutch lake). Commonly regarded as a transferred use of leech (n.2), but the Old English forms suggest a distinct word, which has been assimilated to leech (n.2) by folk etymology [see OED]. Figuratively applied to human parasites since 1784.

leech (n.2)

obsolete for "physician," from Old English læce, probably from Old Danish læke, from Proto-Germanic *lekjaz "enchanter, one who speaks magic words; healer, physician" (cognates: Old Frisian letza, Old Saxon laki, Old Norse læknir, Old High German lahhi, Gothic lekeis "physician"), literally "one who counsels," perhaps connected with a root found in Celtic (compare Irish liaig "charmer, exorcist, physician") and Slavic (compare Serbo-Croatian lijekar, Polish lekarz), from PIE *lep-agi "conjurer," from root *leg- "to collect," with derivatives meaning "to speak" (see lecture (n.)).

For sense development, compare Old Church Slavonic baliji "doctor," originally "conjurer," related to Serbo-Croatian bajati "enchant, conjure;" Old Church Slavonic vrači, Russian vrač "doctor," related to Serbo-Croatian vrač "sorcerer, fortune-teller." The form merged with leech (n.1) in Middle English, apparently by folk etymology. In 17c., leech usually was applied only to veterinary practitioners. The fourth finger of the hand, in Old English, was læcfinger, translating Latin digitus medicus, Greek daktylus iatrikos, supposedly because a vein from that finger stretches straight to the heart.
