Pronunciation

  • Classical: [fuːˈrʊŋ.kʊ.ɫʊs][1]
  • Ecclesiastical: [fuˈruŋ.ku.lus][1]

Forms

fūrunculus m (genitive fūrunculī); second declension[1]

Etymology

It is formed from Latin fūr + -unculus, a diminutive of the word for “thief”.[2][1] Wiktionary notes that the ending -unculus, usual with n-stems, may have come from latrunculus “robber”.[1]

Georges kept the word for a boil apart, suggesting a link with furvus “dark”.[3] Ancient grammarians explained the boil as ⟨fervunculus⟩, named for its heat (fervor).[4][5]

Earliest recorded meaning

It is first found in Cicero's speech against Piso, meaning a petty thief: a man who was once a pilferer and is now a robber.[2][6]

Semantic evolution

By a transfer the OLD and L&S keep under the same word, it named a boil in the medical writer Celsus and in Pliny the Elder,[2][6] and, in Columella and Pliny, a knob left on a vine after pruning.[2]

The thief sense lasted into Medieval Latin,[7] and Anglo-Saxon glossaries use the word for a ferret or marten.[8][7] The medical sense is the source of English furuncle.[9]

Timeline

  • 81–43 BC – Cicero uses it of a petty thief.[2][10]
  • 14–37 AD – Celsus uses it of a boil.[2][10]
  • 1st century AD – Columella uses it of a knob on a vine.[2][10]
  • 1670s – English borrows it as furuncle.[9]

Meanings

Noun

  1. A petty thief, pilferer.[2][6]
  2. A boil, furuncle.[2][6]
  3. A knob left on a vine after pruning.[2]
  4. (Medieval Latin) A ferret.[7][8]

Usage notes

Georges and Gaffiot give the thief and the boil as two words,[3][11] while the OLD treats them as one.[2]
