Pronunciation

Forms

deceniu n (plural decenii)[1] A rare feminine variant decenie, modelled on French décennie, occurs in Mihăescu: „cu o decenie și mai bine mai în vârstă decât dânsa” “older than her by a decade and more”.[2][3][4]

Etymology

It is borrowed from Latin decennium (“a period of ten years”), a learned loan, and possibly also borrowed from Italian decennio.[3][5][6][1] The DLR adds French décennie to the sources, and DELR explains the rare feminine variant by the French word.[2][3] The Latin noun is formed on decennis (“of ten years”) with the suffix -ium,[7] itself made of decem (“ten”) and annus (“year”).[3]

Earliest recorded meaning

DELR's first record is from 1845, in the Magazin istoric pentru Dacia, with the sense “a period of ten years”.[3] MDA2 dates it later, to Maiorescu's Critice, which speaks of “the last decades” of Romanian culture.[4][2]

Semantic evolution

The word has kept a single sense, a span of ten years, as a synonym of decadă.[3][5][4] Eminescu's line „Clipele vor fi decenii” “the moments will be decades” is quoted by the dictionaries of the classics.[8][2] It is usually counted within a century: al doilea deceniu al secolului al XVII-lea “the second decade of the 17th century”.[2]

Timeline

  • 1845 – first record, in the Magazin istoric pentru Dacia.[3]
  • 1862 – the related adjective decenal “lasting ten years; recurring every ten years”, from Latin and French.[3]
  • 1867–1892 – decenii in Maiorescu's Critice.[4][2]
  • 1929 – Șăineanu's dictionary defines it as an interval of ten years.[9]

Meanings
