单词 indigo
释义 indigo, n. (a.)|ˈɪndɪgəʊ|
Forms: α. 6–8 indico. β. (6 endego), 6– indigo.
[Occurs from 16th c., in the two forms indico, indigo, repr. two Romanic forms, from L. indicum (Pliny), a. Gr. ἰνδικόν (Dioscorides) the blue Indian dye, lit. ‘the Indian (substance)’, n. use of neuter of Ἰνδικός, Indicus, Indian. Indico, ? from Sp., was the usual form in 16–17th c., and continued into the 18th; endego occurs in R. Eden 1555 (from the It. of Ramusio Itinerario (Venice, 1550), transl. a Portuguese list of prices at Calicut and Malabar), and indigo in the 1598 transl. of Linschoten, from Dutch, app. also of Indo-Portuguese origin; but this form came into general use only after the middle of the 17th c.: cf. also F. indigo, 1658 in Hatz.-Darm.
The usual name in the Mediterranean countries, before the Portuguese went to India, was annil, anil, which came west, through Arabic and Persian, from Sanskrit: see anil. But indaco occurs in It. in 1390: see Voc. della Crusca, s.v.]
A. n.
1. a. A substance obtained in the form of a blue powder from plants of the genus Indigofera, N.O. Leguminosæ, and largely used as a blue dye.
It is produced by the decomposition of the glucoside indican, which exists not merely in the indigo-plant, but in woad and various other plants. Its essential constituent is indigo-blue; besides which, however, commercial indigo or crude indigo contains indigo-red, indigo-brown, and some earthy glutinous matters (indigo-gluten).
