Pronunciation

  • /əˌkjuːm.jəˈleɪ.ʃən/[1]

Etymology

It is borrowed from Middle French accumulacion, also accumulation, and its source Latin accumulātiō (“a heaping up”),[2][3][4] a noun of action from accumulō (“to heap up, amass”),[2][5][6] formed from ad- (“to”), here perhaps emphatic, and cumulō (“to heap up”), from cumulus (“heap”).[5] Etymonline traces the Latin noun to a suffixed form of Proto-Indo-European *keue- (“to swell”).[5] The French word meant an accumulated mass from 1336 and the action of accumulating from 1401;[2] compare Italian accumulazione and Spanish acumulación.[2]

Earliest recorded meaning

Both an accumulated mass and the action of heaping up: 1490, in Caxton's translation Eneydos.[2] Etymonline gives the sense "that which is heaped up" from the late 15th century, and "act of heaping up" from about 1600.[5]

Semantic evolution

The word soon passed from physical heaps to wealth: the growth of money or capital, especially by the steady addition of interest, is recorded from before 1661.[2][4] At Oxford University, from 1692, it named the practice of taking a higher and a lower degree together or at a shorter interval than usual,[2][4] and in the Church, from 1855, the saying of several offices together.[2] In geology, from 1864, it was used of the growth of a mountain by material piled on its surface, as in mountain of accumulation.[2] Johnson (1755) gave "the act of accumulating" and "the state of being accumulated".[7]
