Middle English clene, going back to Old English clǣne "free from impurities or dirt, unblemished," going back to West Germanic *klainja- (whence also Old Saxon klēni "slender, perceptive," Middle Dutch cleine, clēne "of superior quality, elegant, slender, small," Old High German kleini, chleine "fine, delicate, clever"), of uncertain origin
On the grounds that Low German klīn and Swiss German khlii, with an ablaut grade *klīn-, require a verbal origin, a base *klein-/*klain-/klin- has been suggested, whence Old Norse klína "to smear, butter (bread)," Old High German giklenan "to stroke, smear," from Indo-European *glei̯H- "smear, make stick" (whence, also with a nasal present formation, Old Irish glenaid "(it) adheres, cleaves," Welsh glynu "to stick, adhere"; cf. clay). This derivation would imply for the Germanic adjective an original meaning "smeared on well, carefully applied," hence "well crafted, of superior quality" > "free of impurities, fine, delicate" > "small" (see F. Heidermanns, Etymologisches Wörterbuch der germanischen Primäradjektiven, Berlin, 1993). The earlier proposal of a connection with Indo-European *gel- "bright, shining," is improbable, as none of the descendants of Germanic *klainja- have this meaning.
