Pronunciation

  • Classical: [ˈkeː.pa][1]
  • Ecclesiastical: [ˈt͡ʃɛː.pa][1]

Forms

cēpa f (genitive cēpae); first declension[1] The OLD heads it caepa; a neuter cēpe or caepe, used in the nominative, accusative and ablative, is as old as Naevius and Ennius.[2][3] Georges notes that most editions now print cepa and cepe.[4]

Etymology

It is probably a loanword from an unknown language.[3] The same word may be reflected in Ancient Greek κάπια (kápia, “onions”), which Hesychius records among the people of Ceryneia;[3][2][1] Wiktionary considers an Anatolian source possible.[1]

Ancient grammarians explained the name from caput (“head”), since the onion is nothing but a head.[5]

Earliest recorded meaning

It is found from Naevius on;[3] in one of his comedies a speaker mentions “the gardener who first brought out the onion”.[2][6]

Semantic evolution

In Classical Latin it is the ordinary word for the onion, Allium cepa.[2][7] Lucilius calls it “tearful” and Columella “weeping”,[2] Varro speaks of people whose words smelled of garlic and onion, and Gellius asks why the people of Pelusium did not eat it.[2] Petronius uses it as a term of abuse.[2]

Köbler records further spellings, such as cīpa, cēba and sēpa, and the senses leek, shallot and chive.[6]

Timeline

  • c. 235–200 BC – Naevius mentions the gardener who first brought out the onion.[2][6]
  • 204–169 BC – Ennius uses the neuter cēpe.[2][3][6]
  • c. 180–102 BC – Lucilius calls the onion “tearful”.[2][6]
  • before 66 AD – Petronius uses it as an insult.[2][6]
  • c. 560–636 AD – Isidore of Seville explains the name from caput.[5][6]

Meanings

Noun

  1. An onion, Allium cepa.[2][7]
  2. (as a term of abuse) Petronius: etiam tu rides, caepa cirrata? “are you laughing too, you curly onion?”[2]

Usage notes

A medieval cepa meaning a tree stump, found in charters of 1039–1056, is a separate word of unclear origin.[6] In Medieval Latin cepa is also a spelling of sēbum “tallow”.[1][8]
