[In 16th c. benjoin, a. F. benjoin (also benjaoy, quoted by Devic from Déterville Dict. Hist. Nat. 1816), repr. Sp. benjui, benjuy (Barbosa 1516), Pg. beijoim (Vasco da Gama 1498), It. benzoi (Venetian records, 1461), for *lo-benzoi, *lo-benjuy, a. Arab. lubān jāwī ‘frankincense of Jāwā’ (Sumatra), by which name benzoin is called by Ibn Batuta c1350 (ed. Paris IV. 228). The lo- appears to have been dropped in Romanic, as if it were the article. The word was naturally much corrupted in European langs.; later It. forms are belgivino, belzuino, mod.L. 1584 belzuinum, whence occas. Eng. belzoin. In Eng., benjoin was soon corrupted to benjamin, which still survives as a synonym. Benzoin, which is farther from the original, and appears to owe its z to the It., began to prevail c1650. From benzoin, was formed a1800 the chemical term benzoic (acid), whence at a later period benzin(e, benzol, and the numerous names of the benzene series.]
