+ ==Pronunciation==
+ * Classical: [ĩːˈsɔm.nɪs]^(Wiktionary)
+ * Ecclesiastical: [inˈsɔm.nis]^(Wiktionary)
+
+ ==Forms==
+ '''īnsomnis''' (neuter īnsomne); third-declension two-termination adjective^(Wiktionary)
+
+ ==Etymology==
+ It is [[af|la|in-|somnus|-is|t1=not|t2=sleep]].^(OLD 2012)^(Wiktionary)^(TLL) [[m|la|somnus]] goes back to [[itc-pro|*swopno-]] and [[ine-pro|*suépno-|t=sleep]], with cognates such as [[sa|स्वप्न|tr=svápna-|t=sleep, dream]] and [[grc|ὕπνος|tr=húpnos|t=sleep]].^(de Vaan 2008) Compare [[exsomnis]].^(TLL)
+
+ ==Earliest recorded meaning==
+ De Vaan and Köbler record it from Cato,^(de Vaan 2008)^(Köbler 2010) but the TLL treats the reading in Cato as a doubtful conjecture and finds it securely from Virgil and Horace on.^(TLL) It means sleepless.^(OLD 2012)
+
+ ==Semantic evolution==
+ It means unsleeping, wakeful, and perhaps also unable to sleep;^(OLD 2012)^(Lewis & Short 1879) Lewis and Short call it poetic and post-Augustan.^(OLD 2012)^(Lewis & Short 1879) Horace uses it of Gyges spending sleepless nights, Ovid of a dragon, and Tacitus contrasts men who were ''insomnes magis quam pervigiles'', sleepless rather than watchful.^(Lewis & Short 1879)^(TLL) Of a night or of care it means without sleep: Virgil has guards spending a sleepless night at play.^(OLD 2012)
+
+ In Ecclesiastical Latin it keeps the sense sleepless,^(Stelten 1995) and in Medieval Latin from Britain it is used of people and of nights, as when Bede writes of brethren spending the night sleepless in prayer and psalms.^(DMLBS)
+
