单词 ballast
释义

ballastn.

Brit. /ˈbaləst/, U.S. /ˈbæləst/
Forms:

α. late Middle English– ballast, 1500s balaste, 1500s balest, 1500s balist, 1500s–1600s ballest, 1500s–1800s balast, 1600s ballaist, 1600s ballaste; Scottish pre-1700 balast, pre-1700 balist, pre-1700 balleist, pre-1700 ballest, pre-1700 ballist, pre-1700 bellast, pre-1700 1700s– ballast.

β. 1500s ballass, 1500s ballesse, 1500s–1600s balasse, 1500s–1600s ballace, 1500s–1600s ballase, 1600s ballais, 1600s ballasse; Scottish pre-1700 ballas.

Origin: Probably either (i) a borrowing from Middle Low German. Or (ii) a borrowing from Dutch. Or (iii) a borrowing from French. Etymons: Middle Low German ballast; Dutch ballast; French ballast.
Etymology: Probably < either Middle Low German ballast (2nd half of the 14th cent.), Dutch ballast (1399), or Middle French ballast (1375; 1416–18 as balast; French ballast), all perhaps ultimately of Scandinavian origin (see below).Equivalent forms are found in many European languages in the late medieval period, probably disseminated by maritime and trade contacts in the Baltic associated with the Hanseatic League. With the forms cited above, compare German Ballast (14th cent.; probably < Middle Low German), Old Swedish barlast (c1400; compare earlier barlastadh loaded with ballast (a1352), Swedish barlast ; also ballast (15th cent.)), Norwegian ballast , Old Danish barlast (1443; Danish ballast ), post-classical Latin ballastrum (1444 in a British source), ballastum (1462 in a British source), Spanish balastro (19th cent.; < English). The priority among these words and the relationships between many of them are unclear. Although many are close in date, the earliest attested appears to be the participial form corresponding to Old Swedish barlast (see above: probably < bar mere (see bare adj.) + last load, cargo: see last n.2), with -rl- becoming -ll- by assimilation, and this is often interpreted as the ultimate etymon. However, it has conversely been suggested that the original coinage was Middle Low German ballast (see above), etymologized < bal bad (see bale adj.) + last load, cargo (see last n.2), the Scandinavian forms in bar- being interpreted as folk-etymological, although this does not appear to be supported by the recorded chronology. Old Danish baglast , lit. ‘back load’ (1622) and Dutch balglast , lit. ‘belly load’ (17th cent.) probably represent later remodelling by folk etymology. The β. forms show loss of final -t , probably immediately after similar forms at ballast v. (see discussion at that entry). In sense 5 probably after similar use of German Ballast in e.g. Ballastwiderstand ballast resistance (1880 in the passage translated in quot. 1896 at sense 5).

Origin: Formed within English, by conversion. Etymon: ballast n.
Etymology: < ballast n. Compare Middle Dutch ballasten (c1412), Middle Low German ballasten , German ballasten (1616), Old Swedish barlastadh , past participle (a1352), French ballaster (1618). Compare earlier ballasting n.The frequent forms without final -t probably arose by analysis of forms with final dental as past tense or past participle forms and formation of an analogical present. Sense 3 probably arose by confusion of these forms with balance n.1 in the early modern period.
