+ * IPA (Ecclesiastical): [ˈsɔm.nus]^(Wiktionary)
+
+ ==Forms==
+ '''somnus''' ''m'' (genitive somnī); second declension^(Wiktionary)
+
+ ==Etymology==
+ It is [[inh|itc-pro|*swepnos]], [[inh|ine-pro|*swépnos|t=sleep]], which regularly became ⟨somnus⟩ through ⟨*swopno-⟩; de Vaan, in view of the Celtic forms, slightly prefers a Proto-Italic ⟨*swopno-⟩.^(de Vaan 2008)^(Wiktionary)^(OLD 2012) He takes the PIE noun to be a thematized form of the r/n-stem seen in [[sopor]], from the root [[m|ine-pro|*swep-|t=to sleep]].^(de Vaan 2008)^(Köbler 2010)
+
+ Cognate with [[sga|súan|t=sleep]], [[cy|hun]], [[sa|स्वप्न|tr=svápna|t=sleep, dream]], [[grc|ὕπνος|tr=húpnos]], [[lt|sapnas|t=dream]], [[cu|сънъ|tr=sŭnŭ|t=sleep]], [[non|svefn]] and [[hit|šupp-|t=to sleep]].^(de Vaan 2008)^(OLD 2012)^(Wiktionary)
+
+ ==Earliest recorded meaning==
+ De Vaan dates it from Plautus.^(de Vaan 2008) Ennius, in the first book of the ''Annals'', has ''somnō lēnī placidōque revinctus'', “bound in gentle, peaceful sleep”.^(OLD 2012)
+
+ ==Semantic evolution==
+ ''Somnus'' is sleep, often in the plural with the same sense, and then sleepiness and, figuratively, sloth, inactivity (Cicero mocks the ''somnus'' of Lentulus).^(OLD 2012)^(Lewis & Short 1879)^(Wiktionary) Figuratively it can mean death.^(Wiktionary) Döderlein says ''somnus'' is the ordinary word, ''[[sopor]]'' the poetic one, which in prose means something that brings on sleep.^(Döderlein 1874)
+
+ Church Latin glosses it “sleep”.^(Stelten 1995)
+
+ ==Timeline==
+ * 204–169 BC – Ennius: ''somnō lēnī placidōque revinctus''.^(OLD 2012)^(Köbler 2010)
+ * c. 250–184 BC – Plautus: ''et vāpulandō et somnō pereō'', “I'm dying from beatings and sleepiness”.^(OLD 2012)^(Köbler 2010)
