Word History

Etymology

borrowed from Latin obēsus "fat, stout," past participle of *obedere, perhaps meaning originally "to gnaw," from ob- "against" + edere "to eat" — more at ob-, eat entry 1

Note: Etymologically obēsus should mean "thin, emaciated," if the sense of the unattested verb *obedere was "to eat away, gnaw," as implied by its components. The Roman writer Aulus Gellius (Noctes Atticae 19.7.3) pointed this out and adduced a passage from the poet Laevius (who is known only from a handful of quotations from his works made by other authors), where the word apparently has the meaning "wasted." Presumably the word went reanalysis after the extinction of the verb. The grammarian Pompeius Festus construed the derivation phrasally as "made fat as if as a result of eating" ("pinguis quasi ob edendum factus").
