Forms
sēmēsus (feminine sēmēsa, neuter sēmēsum); first/second-declension adjective[1] In Virgil some editors print the four-syllable form sēmiēsus, read with three syllables;[2][3] Ribbeck writes semessus.[3]
Etymology
It is from Latin sēmi- (“half”) + ēsus (“eaten”),[4][1][5] the second part being the past participle of edō1 (“to eat”).[4] De Vaan traces that verb to Proto-Italic *ed- (“to eat”) and Proto-Indo-European *h1éd-mi (“to eat”), and explains the long vowel of the participle by Lachmann's law, from a sequence /dt/.[6] The prefix goes back to Proto-Indo-European *sēm-i (“in one”), a locative whose meaning shifted from “in one” to “one of the two” and then to “half”.[6]
Earliest recorded meaning
Georges cites it from a tragedy of Pacuvius quoted by Cicero, of half-eaten remains (reliquiae);[3] Köbler's first source is Cicero.[7] Lewis and Short, who do not list that fragment, call the word not earlier than Augustus.[2]
Semantic evolution
It means half-eaten or partly eaten.[4][2] Virgil uses it of prey and of bones, Horace of fish and of scraps of bacon, Ovid of snakes and Juvenal of a hare.[2][3] Suetonius has semesa obsonia, dishes already started, leftovers from the table;[8][2] Petronius uses it of the bodies of children and Florus of food.[2]
In British medieval Latin it keeps the sense half-eaten and is also used, by extension, of a body or of lips half eaten away by hunger or by leprosy.[9]
