Origin: 15th century ;

 Middle English, "inattentive, lazy," borrowed from Latin torpidus "numbed, paralyzed," adjective derivative corresponding to the stative verb torpēre "to be numb, lack sensation, be struck motionless, be sluggish or lethargic," going back to dialectal Indo-European *tr̥p-eh2- (whence also Old Church Slavic trĭpěti "to be patient, suffer," Lithuanian tirpstù, tir͂pti "to become stiff, lose feeling, fall asleep [of limbs]"), zero-grade derivative of a verbal base perhaps see:n also in the Germanic adjective *þerba- (from *terp-o-), whence Old English þeorf "unleavened," Old Frisian therve, derve "rough, violent," Old High German therp, derp "unleavened," Old Icelandic þjarfr "unleavened, fresh (of water), insipid, flat";

  * Note : The base *terp- "grow stiff" appears to be limited to Italic, Germanic and Balto-Slavic. There is a homonymous base *terp- "be satisfied," under which is usually placed the Germanic preterit-present verb *þarf "be under a necessity, need," whence German dürfen "to be allowed or permitted (to do)." Pokorny's Indogermanisches etymologisches Wörterbuch takes *terp- "grow stiff" as a root extension" of a more basic stem *(s)ter-, which, by way of unconditioned ablaut and root extensions, supposedly gives rise to a vast array of vocabulary.;
