Synonym discussion

Sense: noun/2

'Soy sauce' is the general English term for the fermented condiment, understood worldwide and safe in any context. 'Shoyu' specifically refers to the Japanese-style version brewed with wheat, giving it a milder, sweeter flavour than Chinese-style soy sauces. 'Tamari' is a type of Japanese soy sauce made with little or no wheat, resulting in a thicker, richer taste and darker colour — it is naturally gluten-free and often preferred for sashimi. 'Soya sauce' is simply the British English spelling of the same product. In a supermarket, a bottle labelled 'shoyu' or 'tamari' will differ noticeably in taste from standard 'soy sauce', so learners should check the label. For everyday cooking and table use, any of these works, but 'soy sauce' is the safest choice when the recipe does not specify a style.

Etymology

ChineseJapaneseDutchEnglish

The word 'soy' arrived in English through the Dutch trade route in the 17th century, borrowed from Japanese 'shōyu' (醬油), which itself came from Chinese 'jiàngyóu' (醬油), meaning ' fermented sauce'. The English word originally referred only to the sauce; over time its meaning expanded to include the bean itself and all its derived products. The soybean plant (Glycine max) has been domesticated in East Asia for over 5,000 years.
