+ '''castus''' (feminine casta, neuter castum, comparative castior, superlative castissimus, adverb castē); first/second-declension adjective^(Wiktionary)
+
+ ==Etymology==
+ It is the old participle of [[careō]] “to lack, be without”, [[inh|itc-pro|*kas-to-]], so originally “free from”.^(de Vaan 2008)^(OLD 2012) The root has no certain Indo-European cognates; de Vaan finds the usual connection with [[ine-pro|*ḱes-|t=to cut]] neither phonetically nor semantically convincing.^(de Vaan 2008)^(Wiktionary) Older dictionaries compared [[grc|καθαρός|tr=katharós|t=pure]].^(Lewis & Short 1879)^(Döderlein 1874)
+
+ ==Earliest recorded meaning==
+ De Vaan dates the adjective from Plautus,^(de Vaan 2008) who has women say they ought to be free from blame.^(OLD 2012) Köbler dates Plautus c. 250–184 BC.^(Köbler 2010)
+
+ ==Semantic evolution==
+ The first sense, with ''ab'', was free from or untouched by something.^(OLD 2012) From this it meant free from vice, upright, unstained in a religious sense, holy, and sexually pure, chaste, or virgin, as the Vestals.^(OLD 2012) Of language it meant pure and faultless.^(OLD 2012) Döderlein distinguishes ''castus'', chastity as a natural purity of soul, from [[pudīcus]], a sense of shame.^(Döderlein 1874)
+
+ In Christian Latin it described a chaste virgin and purity of faith.^(DMLBS) It survives in [[it|casto]] and [[es|casto]], and Old French ''chaste'' gave [[en|chaste]].^(Wiktionary) Portuguese ''casta'' means “breed, race”.^(Köbler 2010)
+
+ ==Timeline==
+ * c. 250–184 BC – Plautus uses it of being free from blame.^(OLD 2012)^(Köbler 2010)
+ * 81–43 BC – Cicero uses it of the chaste Vestal priestesses.^(OLD 2012)^(Köbler 2010)
+ * c. 165 AD – Gellius uses it of Caesar's pure style.^(OLD 2012)^(Köbler 2010)
