History and Etymology for clean

Adjective

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

Note: 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.
