Pronunciation

Forms

obèse (plural obèses)[1]

Etymology

It is borrowed from Latin obēsus (“well-fed, fat, plump”).[2][3][1][4] The Latin word is the past participle of obedō (“to gnaw, eat away”), from ob- and edō (“to eat”).[5][6][7] Rey explains that the Latin participle properly meant gnawed, hence lean, a very rare sense; in the imperial period it took the opposite, active sense of one who devours, hence fat.[5]

Earliest recorded meaning

It was borrowed late, by Brillat-Savarin in 1825, who used it both as a noun and as an adjective for an excessively fat person.[2][5] The Grand Robert and the GLLF date it 1826.[6][8]

Semantic evolution

The word is used both in everyday language and in medicine for an abnormally fat person, and by analogy for something unusually large.[5][8] The noun obésité is much older: it was borrowed from Latin obēsitās in 1550.[5][3]
