Pronunciation

  • Classical: [ˈnɛɡ.dũː][1]
  • Ecclesiastical: [ˈnɛk.dum][1]

Forms

necdum (not comparable); also nequedum[2][3] The fuller form nequedum is rare: Plautus, Terence, Cicero, Caesar, Celsus, Tacitus and Fronto have it.[3] Both are also written separately, and Livy once separates them with other words in tmesis.[2][3]

Etymology

It is from Latin nec (“and not”) + -dum (“still, for a while”).[2][3] The TLL, following de Vaan and Dunkel, traces the particle -dum to Proto-Indo-European *duh₂- (“far, long”), the root of dūdum (“some time ago”).[3][4] De Vaan takes neque from Proto-Italic *ne-kʷe (“and not”), Proto-Indo-European *ne (“not”) with the enclitic “and”, and nec partly as its shortened form.[4] The grammarian Priscian notes that ⟨dum⟩ after ⟨nec⟩, ⟨nōn⟩ or ⟨haud⟩ is a temporal adverb, as in nōndum (“not yet”).[3]

Earliest recorded meaning

The TLL finds nequedum in Plautus, who writes of a girl who “does not yet” sleep with men, and the form necdum first in a line of Plautus' Pseudolus.[3][2]

Semantic evolution

As a conjunction it means “and not yet” or “but not yet”, as Cicero's “Cassius sent a silly letter, and Bibulus' had not yet arrived”.[2] Repeated, it means “not yet either … or”, as Virgil's men who had not yet heard war trumpets or swords ringing on anvils, and with a following et or -que it means “while not yet … yet at the same time”.[2] The TLL notes that necdum is frequent in verse from Catullus, Lucretius and Virgil on, often at the start of a line, and in prose from Cicero, Varro and Livy throughout Latin.[3]

As a plain adverb, “not yet”, the same as nōndum, it is found in Seneca the Elder, Columella and Tacitus.[2][5] Glossaries render it with Ancient Greek οὐδέπω (oudépō),[3] and medieval writers use it as nōndum.[6][7]

  • 81/79–52/50 BC – Catullus has necdum.[8][3]
  • 70–19 BC – Virgil uses it, often at the start of a line.[2][3][8]
