/ˈsəbsədns/

Origin: A borrowing from Latin. Etymons: Latin subsīdentia, French subsidence.

Etymology: < classical Latin subsīdentia process of coming to rest, action of settling, sediment < subsīdent- , subsīdēns , present participle of subsīdere subside v. + -ia -ia suffix¹; compare -ence suffix. In sense 1a perhaps also partly < French subsidence sediment (1557 in Middle French in a medical context, from 1570 in non-medical contexts); compare also Spanish subsidencia sediment (1573), Italian sussidenza sediment (a1698). Compare subsidency n. N.E.D. (1914) gives both pronunciations. The traditional pronunciation, which is given first, places the stress on the second syllable, but the form with the stress on the first syllable, under the influence of residence n.¹ and subsidy n., is recorded from the early 20th cent. and has gained in currency.

†a. Material that has settled to the bottom of a liquid; sediment; a precipitate or residue. Obsolete.
