Pronunciation

  • Classical: [akˈkʊ.mʊ.ɫoː][1]
  • Ecclesiastical: [akˈkuː.mu.lo][1]

Forms

accumulō (present infinitive accumulāre, perfect active accumulāvī, supine accumulātum); first conjugation[1] It is also spelt adcumulō.[2][3]

Etymology

It is from Latin ad- + cumulō (“to heap up”),[2][4][5] and cumulō is formed from cumulus (“heap, pile”).[1][5] De Vaan notes that the verb is attested much earlier than the noun, and reconstructs Proto-Italic *kumo- and Proto-Indo-European *ḱuh₁-mo- (“heap”), comparing Ancient Greek κῦμα (kûma, “wave, swell”);[6] Schrijver doubts the link with the root “to swell” because of the short /u/.[6]

Earliest recorded meaning

De Vaan has it from Lucretius on,[6] who uses it of death piling up crowded bodies in heaps, and of piling slaughter on slaughter.[3][7]

Semantic evolution

The TLL counts two uses in Cicero and calls it a word suited above all to poets, which passed into the prose of the Silver Age.[5] Cicero uses it of amassing money,[3] and an epitaph of a Scipio boasts of having added to the virtues of the family by the speaker's own conduct.[2][3] Virgil uses it of heaping gifts on the soul of a grandson,[2][7] and Pliny the Elder uses it as a gardening term for heaping soil round the roots of plants.[2][3] Gellius uses it of piling up words.[3]

Medieval writers use it of collecting and counting together (Bede of adding up a number), of increasing, and of paying; in medicine the MLW records an astringent remedy.[8] English accumulate (1520s) comes from its past participle.[9]
