Pronunciation

  • Classical: [ˈnoːn][1]
  • Ecclesiastical: [ˈnɔn][1]

Forms

nōn (negative particle)[1]

Etymology

It is probably from the Old Latin form noenum,[2][3] which de Vaan explains as from Latin ne- (“not”) + ūnum (“one”), “not one”, from *ne-oinom.[4] The long /oː/ can only be explained by a contraction of *ne-oino- to *nōino-, and the loss of the final ⟨-um⟩ is irregular, perhaps because the word was unstressed.[4] Wiktionary calls the origin uncertain and mentions another proposal, Proto-Indo-European *nó-h₁ ne (“not at all”), compared with Gaulish nane (“not”).[1]

Earliest recorded meaning

It appears from Naevius on;[4][5][6] Plautus also has noenum and Lucilius noenu.[4][5][6]

Semantic evolution

In Classical Latin it is the regular negative of a statement, of a single word (nōn magnus), and in questions expecting “yes” (compare nōnne).[2] It also answers a question (“no”), and with a noun it can mean “non-” (nōn corpus, a thing that is not a body).[2] Quintilian criticized its use with a jussive subjunctive in place of nē.[2]

Ennius, Lucilius and Varro are quoted for the old form noenum (noenu).[6]

Timeline

  • c. 235–200 BC – First recorded in Naevius.[4][5]
  • c. 250–184 BC – Plautus uses both nōn and noenum.[6][5]
  • c. 35–95 AD – Quintilian censures nōn with the perfect subjunctive in prohibitions.[2][5]

Meanings

  3. (in answers) no.[2]
  4. (with a noun) That which is not, non-.[2]
