soy

Pronunciation

• /sɔɪ/^[1]

Etymology

It is probably borrowed from Dutch soja,^{[2][3][4][5][6]} from “soi”, the Satsuma (Kagoshima) pronunciation of Japanese 醤油 (shōyu, “soy sauce”),^[7][8] from a Middle Chinese compound,^[7][4] compare Chinese 醬油 (jiàngyóu, “soy sauce”), from 醬 (jiàng, “bean paste”) and 油 (yóu, “oil”).^[6][7][8] Etymonline, Barnhart, Ayto and Weekley give the Chinese source as “shi-yu”, "salted beans" + "oil".^{[3][2][9][10]} The OED does not insist on Dutch, and notes that a route through Malay has been suggested but that the word is not found in that language.^[7] Barnhart argues for Dutch transmission, since the Dutch traded with Japan throughout the period, from 1624 to 1868, when the English had no contact with it.^[2][11] The form soya is the Dutch one.^[9][11][5]

Earliest recorded meaning

A sauce made from fermented soybeans: 1679, as saio according to Barnhart,^[2][12][3] and 1696, as souy, in J. Ovington's Voyage to Suratt, the OED's first quotation.^[7][2] Etymonline describes the early sauce as one used with fish.^[3]

Semantic evolution

The OED notes that the Japanese word refers only to the sauce, the bean being called daizu, "large bean", and that the English word too first meant the sauce.^[7] It was then used of the plant, from 1778,^[7] probably by way of soybean and helped by the botanical Latin soja in the plant's former names.^[7] The compound soy sauce is recorded from 1795.^[3][2] From 1945 soy also meant flour, meal or protein made from soybeans and used in foods, often in place of meat.^[7] Collins notes that soy for the plant is American and Canadian, where British English says soya.^[13][6]
