First attested

Pronunciation

  • Classical: [ˈsiː.bɪ.ɫʊs][1]
  • Ecclesiastical: [ˈsiː.bi.lus][1]

Forms

sībilus m (genitive sībilī); second declension[1]

Etymology

It is an onomatopoeic word.[2][3][1] De Vaan notes that the verb sībilō (“to hiss”) is recorded earlier than the noun, and takes the word to imitate a sound /siːb/, or /siː/ with a suffix.[3] The OLD compares Ancient Greek σίζω (sízō) and ψίθυρος (psíthuros).[2] Köbler connects it with Proto-Indo-European *su̯ei- (“to hiss, whistle”),[4][5] and Wiktionary reports a derivation by Gamkrelidze and Ivanov from *sweysd- (“to hiss”).[1]

Earliest recorded meaning

It is found from Pacuvius on,[3][4] of the whistling of the ships' ropes, rudentum sibilus.[2][6]

Semantic evolution

It was any hissing or whistling sound: of snakes and other animals, of the wind and of things, and of a shepherd's pipe.[2][7] Livy has a whistle used as a signal, and Columella cattle called by whistling.[8][7] Cicero uses it for the hissing of an audience: a man driven off the stage by hisses and abuse, and the taunt sibilum metuis? “are you afraid of being hissed?”.[2][6] The poets use the neuter plural sibila for metrical reasons.[8][2]

Medieval writers in Britain use it of the hiss of a serpent, and of a person's whisper or whistle and the whispering of the breeze.[9]

Timeline

  • 220–130 BC – Pacuvius writes of the whistling of the ropes.[2][4]

Word family

Usage notes

A rare ablative sibilu occurs in Sisenna and a neuter singular sibilum in Celsus.[2][6] There is also an adjective sībilus “hissing”, found only in the neuter plural sibila (of snakes' necks in Virgil), which the OLD and Georges list as a separate word.[2][7][8]
