+ '''cōnscientia''' ''f'' (genitive cōnscientiae); first declension^(Wiktionary)
+ The plural is rare.^(OLD 2012)
+
+ ==Etymology==
+ It is from [[cōnscius]] or [[cōnsciō]] “to be aware” with the suffix [[-ia]], a calque of [[grc|συνείδησις|tr=suneídēsis|t=joint knowledge; conscience]].^(OLD 2012)^(Wiktionary) ⟨Cōnsciō⟩ is from [[con-]] and [[sciō]] “to know”, which de Vaan thinks probably a back-formation from ⟨nescīre⟩, perhaps from a root meaning “to cut, distinguish”.^(de Vaan 2008)
+
+ ==Earliest recorded meaning==
+ The OLD's earliest citations are from Cicero, of knowledge shared with others.^(OLD 2012) Köbler dates Cicero 81–43 BC.^(Köbler 2010)
+
+ ==Semantic evolution==
+ It was knowledge held in common with others, joint knowledge, complicity, as in Cicero; awareness of something one has done, consciousness, as in Seneca; and, with ''animī'' or ''mentis'' or alone, the inward sense of the rightness or wrongness of one's actions, conscience, as in Cicero.^(OLD 2012)^(Lewis & Short 1879)
+
+ In Ecclesiastical Latin it meant conscience, consciousness, acknowledgment.^(Stelten 1995) British Medieval Latin used it for shared knowledge and complicity in guilt.^(DMLBS) [[en|conscience]] (about 1200, “the faculty of knowing what is right”) came through Old French and directly from Latin.^(Etymonline) It also survives in Italian ''coscienza'' and French ''conscience''.^(Wiktionary)
+
+ ==Timeline==
+ * 81–43 BC – Cicero uses it of joint knowledge and of conscience.^(OLD 2012)^(Köbler 2010)
