+ '''ōmentum''' ''n'' (genitive ōmentī); second declension^(Wiktionary)
+
+ ==Etymology==
+ Its origin is uncertain.^(de Vaan 2008) The OLD derives it from *ouimentum, from the root of [[induō]] “to put on”, as Walde and Hofmann did, but de Vaan sees no support for this in the meaning, and *owe-mento- would have given *ūmentum.^(OLD 2012)^(de Vaan 2008) Ernout and Meillet suspected a borrowing, perhaps from a word like [[xum|umen|t=ointment]], the Sabellic cognate of [[unguen]] “fat, ointment”, from [[ine-pro|*h₃éngʷn̥|t=fat, butter]].^(de Vaan 2008)^(Wiktionary)
+
+ ==Earliest recorded meaning==
+ De Vaan dates it from Catullus.^(de Vaan 2008) Köbler dates Catullus 81/79 to 52/50 BC.^(Köbler 2010)
+
+ ==Semantic evolution==
+ It meant the fatty membrane covering the intestines, the caul, and more generally fat, as Persius' sacrificial attendant whose belly shakes with fat, and then the bowels.^(OLD 2012)^(Lewis & Short 1879)^(Gaffiot 2016) Celsus and Pliny the Elder use it in medicine, and Isidore of Seville calls it the membrane the Greeks name ''epíploon''.^(Gaffiot 2016)^(Isidore)
+
+ In Medieval Latin it was the caul, glossed in Old English.^(DMLBS) [[en|omentum]] is a borrowing of it.^(Wiktionary)
