cleanadj.

Brit. /kliːn/, U.S. /klin/
Forms: Old English clǽne, (Old English, Middle English cláne, Middle English clone), Old English–1500s clene, Middle English–1600s cleane, (Middle English–1500s cleyn(e), Middle English–1600s cleen(e, (Middle English clen, kleane, klene, Middle English, 1600s clayne), 1500s– clean.
Origin: A word inherited from Germanic.
Etymology: Common Germanic: Old English clǽne < preh. *cláni- < West Germanic *klaini: compare Old Saxon clêni, cleini, Old Frisian clêne, cleine, Middle Dutch, Middle Low German cleine, clêne, Low German and Dutch kleén, klein, Old High German chleini clear, pure, clean, neat, delicate, fine, tiny, small, puny, Middle High German klein(e, modern German klein small, little; also Icelandic klénn snug, little, puny, Swedish klen thin, slight, weak, Danish klein, weak. The original sense was ‘clear, pure’; Old High German shows how this passed into the modern German sense ‘little’; the original sense is more nearly retained in English, where, however, it has been encroached upon by the Romanic clear and pure. The final -n , -ni , is suffixal; the stem klai- is by some referred to the verb-stem klî- , klai- , kli- ‘to stick’, with the suggested connection of sense that sticky things, such as oil, give a clear surface, or ‘make the face to shine’. Compare also the ancient practice of anointing, with its associations. The early variants cláne , clone , are apparently due to a mixture of the original adjective clǽne with the original adverb cláne : compare soft n.
I. That is clear in quality; free of encumbrance.
1. Clear.
a. Free from anything that dims lustre or transparency. Obsolete.In later use passing into sense 2.

5. Without anything omitted or left; without any exception that may vitiate the statement, without qualification; wholly, entirely, quite, absolutely.This sense naturally arose from the consideration that when a substance is taken entirely out of any vessel, etc., without leaving a particle behind, the vessel is left clean, and its cleanness is a measure of the completeness of the removal. Hence clean was naturally used with all verbs of taking, driving, or going away, of losing, and thence of finishing up, completing, or performing any action.
a. with verbs of removal, and the like. (The use of adverbs or prepositional phrases qualifying the verb introduces const. c.)
