soy-based

the word 'soy-based' is a modern english compound adjective formed in the 20th century, reflecting the increased use of soy as an industrial and culinary ingredient. the first element, 'soy', has a long journey from the chinese term for fermented soybean sauce, entering european languages via japanese and dutch trade, and coming to denote the bean itself. the second element, 'based', utilizes the past participle of the verb 'to base', which originates from the greek concept of a foundation or pedestal. combined, the term literally means 'having soy as its foundation', logically describing products or materials primarily derived from soybeans, a meaning that directly extends from its constituent parts.

Structure: soy (plant/bean) + based (having as a foundation) soy (from japanese 醤油 'shōyu' via dutch 'soja', ultimately from chinese 豉油 'chǐyóu', referring to the soybean and its sauce); based (from english base, from old french 'baser', from latin 'basis', from greek 'basis' (step, pedestal), functioning as an adjective-forming suffix meaning 'having as a foundation or primary constituent').
