Forms

rot m (plural rots)[1] Anglo-Norman rut, Old French rout;[2][3][4] rot is found from about 1560.[2][3][4]

Etymology

It is inherited from Old French rout, inherited from Late Latin ruptus (“belch”), a 4th-century alteration of ructus (“belch”) of the same sense.[3][2][5][6] The change is put down, perhaps, to the past participle of rumpō (“to break”).[2][4][7] The Latin noun goes with an old verb rūgō of the same root as rūgiō (“to roar”), and survives in the prefixed ērūctō, the source of éructer.[3] The vowel /o/ replaced the older /u/ because it was felt to be more expressive.[3][7]

Cognate with Old Occitan rot and Italian rutto.[7][8]

Earliest recorded meaning

It is first found as rut in the Anglo-Norman lapidaries of the mid-12th century, and as rout about 1270 in the Lapidaire de Berne, with its modern sense.[2][4]

Semantic evolution

Villon rhymes petz et rottes in the Grand Testament, and Ambroise Paré lists rots aigres et puants among the signs of a sick stomach in the 16th century.[8] In modern French it is a popular or vulgar word, like pet;[3] Littré already calls it low and gives éructation as the medical term.[8]

From the early 20th century it is also used of a similar noise from inside a thing,[3][4] and Flaubert used it in literary prose for the return of unpleasant memories.[3][4] The childish reduplication rototo (20th century) names a baby's burp after feeding.[3]
