indigo

indigo: [16] Etymologically indigo, a blue dye, is the ‘Indian dye’ – so named because supplies of it were obtained from India. The term is an ancient one. It originated in Greek indikón, literally the ‘Indian substance’, a derivative of the adjective Indikós ‘Indian’, and passed via Latin indicum and Spanish indico into English as indico.

This was replaced in the 17th century by the Portuguese form indigo, and it was Portuguese influence, stemming from their commercial activities in India, that really established the term among the European languages (hitherto the commoner term for the dye had been anil, a word of Sanskrit origins). (The name India, incidentally, to which indigo is related, comes ultimately from Old Persian hi?d’u, which originally meant ‘river’, was subsequently applied specifically to the river Indus, and finally became the name for the country through which the Indus flowed.)
