Etymology and origin of the Latin word cumulo

Confidence
Probable
Formation
Derivation
First attested
c. 250–184 BC, Plautus
Ultimate origin
Proto-Indo-European (*ḱuh₁-mo-)

Pronunciation

  • Classical: [ˈkʊ.mʊ.ɫoː][1]
  • Ecclesiastical: [ˈkuː.mu.lo][1]

Forms

cumulō (present infinitive cumulāre, perfect active cumulāvī, supine cumulātum); first conjugation[1] An inscription spells it comul-.[2]

Etymology

It is formed from cumulus (“heap”) with the verb suffix -ō.[3][2][4] De Vaan derives ⟨cumulus⟩ from Proto-Italic *kumo- and Proto-Indo-European *ḱuh₁-mo- (“heap”), cognate with Ancient Greek κῦμα (kûma, “wave”), and notes that the verb is attested much earlier than the noun;[5] Schrijver doubts the link with the root “to swell” because of the short ⟨u⟩.[5]

Earliest recorded meaning

Plautus has “now is the chance to heap up good deeds” in the Captivi.[3]

Semantic evolution

It is to gather into a heap or pile up, as Lucretius' matter lying heaped together, and to amass, as Livy's goods gathered by long good fortune.[3][6] Figuratively it is to accumulate, and to heap honours on someone, as in Livy.[3][6] It is to cover as with a heap, load or fill to overflowing, as the Bellum Hispaniense of enemies pierced by javelins, to load someone with gifts, as Virgil's Aeneas who loads Acestes with great presents, and with honours or misfortunes, as Cicero's house loaded with double disgrace.[3][6][1] It is to increase or enhance, and to crown or bring to perfection, as Cicero's “only the sight of you was missing to make my joy complete”.[3][6][1]

Church Latin glosses it “increase, fill up, heap up, enlarge”.[7] English cumulate in the 1530s meant to gather into a heap.[4]
