Etymology

Its origin is uncertain; the OLD calls it doubtful, and de Vaan gives it no etymology, according to Etymonline.[2][3] Wiktionary and Köbler derive it from Proto-Indo-European *seyb- (“to pour out, drip”), whence through Germanic also sāpō “soap”.[1][4] It is also spelled ⟨sēvum⟩, as in Columella.[2][5]

Earliest recorded meaning

Lewis and Short's earliest example is from Plautus, of tallow.[5] Köbler dates Plautus c. 250–184 BC.[4]

Semantic evolution

It meant hard animal fat, suet, tallow, grease, as in Plautus, Caesar, Columella and Pliny the Elder.[2][5][6]

British Medieval Latin used it for tallow, with the forms sevum and sepum.[7] It survives in Italian sevo, French suif and Spanish sebo, and an Anglo-French diminutive of Old French siu gave English suet in the early 14th century.[1][3] English sebum became a medical term in 1728.[3]
