Formation
Derivation
First attested
c. 250–184 BC, Plautus
Ultimate origin
Proto-Indo-European *keh₂id-

Forms

caestus m (genitive caestūs); fourth declension[1] It is also spelled cestus, as in Varro, and Plautus has a form cestum; the ablative plural is cestīs in Varro and caestīs in Hyginus.[2]

Etymology

The OLD and Wiktionary derive it from caedō “to strike, cut”; the TLL calls its origin uncertain, perhaps from that verb.[2][1][3] De Vaan traces caedō to Proto-Italic *kaid-e/o- and Proto-Indo-European *keh₂id- (“to cut, hew”).[4]

Earliest recorded meaning

Köbler's earliest source is a passage of Plautus' Bacchides that he treats as not genuine,[5] where the OLD reads the form cestum.[2]

Semantic evolution

It is a strip of leather, especially one weighted with lead or iron and bound round the hands and arms of boxers, a boxing glove, and by extension boxing itself.[2][6] Cicero and Virgil use it.[6] The grammarian Probus distinguishes it from cestus, the girdle of Venus, in spelling and declension.[3]

Timeline

  • c. 250–184 BC – A passage of Plautus has the form cestum.[2][5]
  • 81–43 BC – Cicero uses the word.[6][5]
  • 70–19 BC – Virgil uses it.[6][5]

Meanings

Noun

  1. A leather strap weighted with lead or iron, worn by boxers; a boxing glove, cestus.[2][6][1]
  2. Boxing.[2]

Usage notes

It is a separate word from cestus “girdle”, especially the love-inspiring girdle of Venus, which comes from Greek kestos “stitched, embroidered” and passed into English in the 1570s.[7][3]
