+ ==Forms==
+ '''rein''' (strong nominative masculine singular reiner, comparative reiner, superlative am reinsten)^(Wiktionary)
+
+ ==Etymology==
+ It is [[inh|gmh|reine]], [[inh|goh|reini]], [[inh|gmw-pro|*hrainī]], [[inh|gem-pro|*hrainiz|t=clean, pure]].^(Kluge 2011|756)^(Wiktionary)^(Kroonen 2013) The same adjective is [[got|𐌷𐍂𐌰𐌹𐌽𐍃|tr=hrains]], [[non|hreinn]], [[osx|hrēni]] and [[ofs|hrēne]], continued in [[nl|rein]] and [[sv|ren]].^(Kluge 2011|756)^(Pfeifer 1993)^(Kroonen 2013) It is missing in Old English, where [[m|ang|clǣne]] (English [[m|en|clean]]) took over its meaning.^(DWB|14, 680)^(Paul 2002)
+
+ Its original sense was “sifted, cleaned”.^(Kluge 2011|756)^(Paul 2002)^(Duden 7 2014|689) It belongs to [[ine-pro|*krey-|t=to separate, sift]], found in [[grc|κρίνω|tr=krī́nō|t=to separate, decide]] and [[la|cernō|t=to sift, distinguish]].^(Kluge 2011|756)^(Pfeifer 1993)^(Wiktionary) Related above all are the words for “sieve”: [[m|la|crībrum]], [[sga|críathar]], and the regional German [[Reiter]] (Old High German [[m|goh|rītara]]), with [[ang|hriddel]].^(Kluge 2011|756)^(Pfeifer 1993)^(Duden 7 2014|689) Pfeifer and the Duden take this root as a form of [[ine-pro|*(s)ker-|t=to cut]], the root of [[scheren]], and the Duden calls the adjective an old participle.^(Pfeifer 1993)^(Duden 7 2014|689) Kroonen explains it as an adjective, perhaps with lengthened grade, formed to a nasal present that Germanic has not kept, the type of the Latin and Greek verbs.^(Kroonen 2013) Swiss dialects keep an old sense “fine”, of flour, sugar or sand, as does Rhenish Franconian.^(Kroonen 2013)^(Pfeifer 1993) Wiktionary also notes another explanation, from [[m|ine-pro|*ḱreyH-|t=to show oneself, noble]].^(Wiktionary)
+
+ ==Earliest recorded meaning==
+ Old High German ''reini'' is recorded from the Benedictine Rule of the last quarter of the 8th century, and then in the Isidor, the Tatian, Otfrid and Notker.^(Köbler AHD)^(EWA|7, 344)^(Schützeichel 2012|257) It meant “clean, pure, clear, chaste, spotless, holy, innocent”, and also “fine” of flour: ''reinaz melo'' glosses Latin ''simila'' “fine wheat flour”.^(EWA|7, 344)
+
+ ==Semantic evolution==
+ Paul distinguishes two main senses.^(Paul 2002) The first, “free of dirt”, the opposite of “soiled”, was originally not usual in Upper German, which said [[sauber]]; in the Bible ''rein'' is also “free of skin disease” and of animals “fit for sacrifice”, and more widely “virgin, free of sin”.^(Paul 2002) The second is “unmixed”: pure gold, wine or wool, a pure colour or pronunciation, Kant's ''reine Vernunft'' “pure reason”, and ''reine Mathematik'' (1764) as opposed to applied mathematics.^(Paul 2002) As an adverb it came to mean “merely” and “downright” (''rein unmöglich'', Schiller), and ''reinweg'' “downright” came from Low German about 1900.^(Paul 2002)
+
+ [[Reinheit]] (1620) replaced older ''Reinigkeit'', and [[reinigen]] replaced older ''reinen''.^(Paul 2002)^(Duden 7 2014|689) In ''Reingewinn'' (1876) ''rein'' renders [[netto]], and ''Reinkultur'' (about 1880) was first a pure culture of bacteria, then anything typical in its purest form.^(Paul 2002) Czech borrowed ''rajn'' “purely, quite”.^(LWP)
+
+ ==Timeline==
