Forms
onéreux (feminine onéreuse, masculine plural onéreux, feminine plural onéreuses)[1] Middle French honereux, honereus, the form used by Oresme.[2][3][4]
Etymology
It is borrowed from Latin onerōsus (“heavy, burdensome”), an adjective of imperial Latin, from onus (“load, burden”).[5][2][6][7] Rey traces the Latin noun to an Indo-European root noun with relatives in Sanskrit and Greek;[2] Littré already compared a Sanskrit word for a cart.[4]
Earliest recorded meaning
It is first found before 1382 in Nicole Oresme, as honereux, meaning burdensome or tiresome: delectation honereuse, ennuyeuse aux bons.[5][4]
Semantic evolution
Until the 16th century the word meant heavy or awkward, and figuratively irksome and hard to bear; that sense has since become dated or literary.[2][5] The sense “costly” seems to have come through law, in à titre onéreux (1611, Cotgrave), said of a thing acquired on condition of a charge or obligation, and inventaire onéreux (1615), an estate with more debts than assets.[2][5] The Académie recorded the sense “that costs a lot of money” in 1694, and this is the main sense today.[5][8]
English onerous (late 14th century) comes from the Old French form and directly from Latin.[9]
