Formation
Onomatopoeia
First attested
34–62 Persius More words from the 1st century

Pronunciation

  • Classical: [ˈɫal.loː][1]
  • Ecclesiastical: [ˈlal.lo][1]

Forms

lallō (present infinitive lallāre); first conjugation, no passive, no perfect or supine stems[1]

Etymology

De Vaan takes it as onomatopoeic, a reduplicated imitation of a baby's sounds;[2] the OLD calls it a child's word.[3] The TLL derives it from lalla (“lullaby”), the nurse's song.[4] Wiktionary allows that it may instead be a reduplicated form of Proto-Indo-European *leh₂-.[1]

Comparable forms are Ancient Greek λαλέω (laléō, “to talk, chat, prattle”), Lithuanian laluóti (“to babble”) and German lallen.[2]

Earliest recorded meaning

It is first found in Persius,[2][4] who asks a pampered man why he refuses to be sung to sleep (lallare recusas).[5][4]

Semantic evolution

The scholiast on Persius explains it from the song that nurses sing to crying children.[4] Jerome uses it of a mother singing a lullaby.[5][4] A Latin–Greek glossary renders it with Ancient Greek βαβάζω (babázō).[5]

Timeline

  • 34–62 AD – Persius uses it of singing a child to sleep.[4][6]
  • c. 383–419/420 AD – Jerome uses it in a letter.[5][4][6]

Meanings

Verb

  1. To sing a lullaby.[3][5]

Usage notes

The OLD notes that a spelling lalō may also have existed.[3]
