Ultimate origin
Proto-Indo-European (*morh₂-)

Pronunciation

  • Classical: [ˈmɔ.rɔr][1]
  • Ecclesiastical: [ˈmɔː.ror][1]

Forms

moror (present infinitive morārī or morārier, perfect active morātus sum); first conjugation, deponent[1] Ennius, Naevius and Pacuvius have the active morō.[2][3] The old infinitive morārier is also found.[1]

Etymology

It is formed from mora “delay”, or, as Schumacher proposed, continues an old iterative ⟨*morH-eye-⟩.[2][4][5][3] De Vaan derives mora from Proto-Italic *morH-ā- (“delay”), from Proto-Indo-European *morh₂-, and compares Old Irish maraid (“lasts, remains”).[3]

Earliest recorded meaning

De Vaan dates it from Naevius, who uses the active form.[3][2] Plautus has cūr nōn vēnistī? – hic mē morātust, “why didn't you come?” – “this man held me up”.[2]

Semantic evolution

Transitively morārī is “to delay, hold up”, “to detain, keep back”, and “to hold the attention of”.[2][4][1] With a negative it means “not to care about, disregard” (Virgil: nec dōna moror, “I care nothing for gifts”), and in the legal formula nihil moror a prosecutor dropped a charge.[2] It also means “to hinder, obstruct” an action.[2][1] Intransitively it is “to delay, wait” (Plautus: ī, sequere illōs, nē morēre, “go, follow them, don't delay”), “to be slow in coming”, and “to stay, stop” somewhere.[2][4][1]

Döderlein contrasts manēre, to stay as opposed to going away, with morārī, to linger as an interruption of movement.[6] Church Latin glosses it “delay, abide, dwell, tarry, linger”.[7]

Timeline

  • c. 235–200 BC – Naevius uses the active morō.[3][2][8]
  • c. 250–184 BC – Plautus: hic mē morātust;[2][8] nē morēre.[2][8]
  • 81–43 BC – Cicero: quid sedēs, quid morāris?, “why do you sit there, why do you delay?”[2][8]
  • 70–19 BC – Virgil: nec dōna moror.[2][8]
  • c. 50 BC – Caesar writes of someone who stopped nowhere in Macedonia.[2][8]

Usage notes

A separate verb mōror, with a long ō, “to be a fool”, from Ancient Greek μωρός (mōrós, “foolish”), occurs only in a pun of Nero's: Suetonius reports that he joked that Claudius had stopped morārī among men, lengthening the first syllable.[4][5][1]
