Pronunciation

  • Classical: [ˈjoː.ta][1]
  • Ecclesiastical: [ˈjɔː.ta][1]

Forms

iōta n[1] A feminine iōta, -ae is found from Ausonius on.[2][3][4] Medieval spellings include yota, yotha and iotha.[5]

Etymology

It is borrowed from Ancient Greek ἰῶτα (iôta), the name of the Greek letter.[6][1][3] Its further origin is unclear;[7] Köbler refers to the name of the tenth letter of the Hebrew alphabet.[7]

Earliest recorded meaning

Cicero (81–43 BC) has it in De oratore: someone imitating Cotta's broad pronunciation is said to drop the letter iota and say a very full e (ut iota litteram tollas).[2][4][7]

Semantic evolution

Martial uses it as the smallest of letters, telling a reader who would rather have the second book be the first to take one iota from its title.[4][2] In Latin verse the word has two syllables, in Greek three.[2][4] Ausonius treats it as a feminine, and the Old Latin Bible has iota una in Matthew 5:18.[4][2]

Medieval writers used it also as the numeral ten and, after the Gospel passage, for the slightest portion, a jot.[8][9]

Timeline

  • 81–43 BC – Cicero writes of dropping the letter iota.[2][7]
  • 40–102/103 AD – Martial uses it as the smallest letter.[2][4][7]
  • c. 310–394 AD – Ausonius treats it as a feminine noun.[2][3][7]
