acaroidn.¹

Brit.

/ˈakərɔɪd/, U.S.

/ˈækəˌrɔɪd/

Forms:

α. 1800s– acaroid, 1900s– accaroid, 1900s– accroid (rare).

β. 1800s– accroides, 1800s– acroides.

Origin: A borrowing from Latin. Etymon: Latin Acaroides.

Etymology: < scientific Latin Acaroides in Acaroides resinifera (C. Kite 1790, in Mem. Med. Soc. 4 (1795) 24), also Acoroides resinifera ( C. Kite Ess. & Observ., Physiol. & Med., on Submersion of Animals (1795) 138), former name of Xanthorrhoea resinosa, the tree from which the resin was first obtained; of uncertain origin, perhaps < Acorus acorus n. + -oides -oid suffix, in which case the tree is so called on account of some similarities between the two plants (e.g., both plants are grass-like and have similar leaves).The β. forms retain the Latin ending, but show loss of the medial -a-. An early description of the resin is in A. Phillip Voy. Botany Bay (1789) vii. 59ff, but it is there referred to only as yellow gum.

A resinous gum obtained from various Australian trees of the genus Xanthorrhoea (family Xanthorrhoeaceae), used (esp. formerly) for preparing varnish, lacquers and waxes, for staining wood, and in medicinal preparations. Frequently attributive, as acaroid gum, acaroid resin, etc. Cf. gum accroides n. at gum n.² 3a.Acaroid resins differ in colour depending on the species of tree they come from: X. resinosa produces yellow resin, X. preissii and others produce red resin.

Brit.

/ˈakərɔɪd/, U.S.

/ˈækəˌrɔɪd/

Origin: A borrowing from Latin, combined with an English element; perhaps modelled on a Latin lexical item. Etymons: Latin Acarus , -oid suffix.

Etymology: < scientific Latin Acarus acarus n. + -oid suffix, perhaps after scientific Latin acaroides, specific name of the pseudoscorpion Phalangium acaroides ( Linnaeus Systema naturæ ed. 12 (1767) I. ii.), originally placed by Linnaeus in the genus Acarus (as A. scorpioides). Compare earlier acarine adj. With the use as noun compare earlier acarine n. 1.
