+
+ ==Etymology==
+ It is [[af|la|cadō|-tus|t1=to fall]], from earlier [[m|la|cassus|alt=cāssus]].^(OLD 2012)^(Wiktionary) The verb is [[inh|itc-pro|*kad-e/o-]], perhaps from [[ine-pro|*ḱh₂d-|t=to fall]].^(de Vaan 2008) The grammatical sense “case” is a semantic loan from [[grc|πτῶσις|tr=ptôsis|t=a falling, case]].^(Wiktionary)
+
+ ==Earliest recorded meaning==
+ De Vaan dates it from Plautus,^(de Vaan 2008) who has a character say that a fall gave great pleasure.^(OLD 2012) Köbler dates Plautus c. 250–184 BC.^(Köbler 2010)
+
+ ==Semantic evolution==
+ Its first sense was a fall, a downward movement of people, rain or snow.^(OLD 2012)^(Lewis & Short 1879) From what “befalls” it meant chance and accident, an event or occurrence, and especially a misfortune or disaster.^(OLD 2012) Grammarians used it of the ending of a word and of grammatical case.^(OLD 2012)^(Wiktionary) Döderlein distinguishes ''cāsus'', chance as a natural agent, from [[fors]], chance thought of as a kind of divine being.^(Döderlein 1874) In Cicero's time the ''s'' was written double, ⟨cassus⟩.^(Lewis & Short 1879)
+
+ In medieval Latin it was a legal problem in a treatise, a lawsuit, a cause and a subject.^(Niermeyer 1976) It survives in [[it|caso]] and [[es|caso]], and through Old French ''cas'' [[en|case]] meant “what befalls one” in the early 13th century.^(Wiktionary)^(Etymonline)
