+ '''castra''' ''n pl'' (genitive castrōrum); second declension^(Wiktionary)
+
+ ==Etymology==
+ It is the plural of [[castrum|t=fort]].^(OLD 2012)^(Wiktionary) The singular is, according to de Vaan, [[inh|itc-pro|*kastro-|t=part, share]], [[m|ine-pro|*ḱs-tro-]], from the root [[ine-pro|*ḱes-|t=to cut]];^(de Vaan 2008) Walde–Hofmann and Ernout–Meillet took it as “a part cut off”, hence “fenced area, property” and “camp”.^(de Vaan 2008) The same base gives [[m|itc-pro|*kastro-|t=knife]], whence [[castrō|t=to castrate]].^(de Vaan 2008)
+
+ Compare [[osc|castrous]] and [[xum|kastruvuf]], perhaps “land, property”.^(de Vaan 2008)
+
+ ==Earliest recorded meaning==
+ It is found from Plautus on: ''in castra ex urbe ad nōs veniunt flentēs prīncipēs'' “the chiefs come weeping from the city to our camp”.^(de Vaan 2008)^(OLD 2012)
+
+ ==Semantic evolution==
+ ''Castra'' is a fortified military camp; by extension it means one side in a war (''castra Pompeī''), military life and service (Cicero sets ''castra'' against the forum), and a day's march (''quīntīs castrīs'' “in five days' marches”).^(OLD 2012)^(Wiktionary) Figuratively it means a sphere of activity, and a philosophical school or sect.^(OLD 2012)^(Wiktionary)
