Earliest recorded meaning

The OLD's earliest citation is from Cicero, of flatulence.[2] Köbler dates Cicero 81–43 BC.[4]

Semantic evolution

In medicine it meant distention of the stomach or intestines with gas, flatulence, as in Cicero, and in Vitruvius expansion, swelling, as of boiling water.[2][5][6]

In Medieval Latin it meant pride.[7] British Medieval Latin used it for distension by air.[8] It survives in Spanish hinchazón “swelling”, and gave English inflation in the mid-14th century, “swelling caused by wind in the body; flatulence”, and figuratively pride.[1][3]
