+ '''mystérieux''' (feminine mystérieuse, masculine plural mystérieux, feminine plural mystérieuses)^(Wiktionary)
+ Middle French [[m|frm|mysterieux]].^(Wiktionary) Old French also had an adjective ''misterial'', as in ''la misterial sepmaine'' “Holy Week” in Jean de Meun.^(Littré 1873)
+
+ ==Etymology==
+ It is [[af|fr|mystère|-eux]].^(TLFi)^(Bloch & Wartburg 1989)^(Grand Robert 2005)^(Wiktionary) [[mystère|alt=Mystère]] was borrowed in the late 12th century from [[la|mystērium|t=rites open only to the initiated; secret]], itself from [[grc|μυστήριον|tr=mustḗrion|t=secret rite, mystery]], which belongs with [[m|grc|μύω|tr=múō|t=to close (the eyes or lips)]].^(DHLF 1992)^(Bloch & Wartburg 1989) The adjective is recorded indirectly a little earlier through its adverb [[mystérieusement]] (1461).^(DHLF 1992)
+
+ ==Earliest recorded meaning==
+ Its first record is in Georges Chastellain's ''Dit de Vérité'', written before 1475, with the sense “having a secret, enigmatic side”;^(TLFi)^(DHLF 1992) the Grand Robert dates it to 1468, the GLLF to about 1460 and the Petit Robert to 1440.^(Grand Robert 2005)^(GLLF 1989)^(Petit Robert 2007)
+
+ ==Semantic evolution==
+ Unlike [[mystère]], whose first senses were religious, the adjective had everyday lay senses from the start.^(DHLF 1992) Rabelais (1552) wrote of ''motz mysterieux'', “words hard to understand”.^(TLFi)^(Littré 1873) Cotgrave (1611) has the sense “containing something hidden or unknown”, and Pascal (before 1662) used it of a person who makes a mystery of things not worth hiding, a use made into a noun by Richelet (1680).^(GLLF 1989)^(TLFi)
+
+ The religious sense “relating to the sacred mysteries” came only in the 17th century, with Bossuet (1675).^(DHLF 1992)^(TLFi) Chateaubriand (1803) used the masculine as a neuter noun, ''le mystérieux'', for the mysterious quality of something.^(DHLF 1992)^(TLFi)
+
+ ==Timeline==
