the word 'tofu' entered english in the late 18th century as a direct borrowing from japanese. the japanese term itself originates from chinese 'dòufu', which is a compound of 'dòu' (bean) and 'fǔ' (rotten, fermented, curdled). this etymology reflects the process of coagulating soy milk to create the food's characteristic curds. the journey from the chinese descriptive term for "curdled bean" to the modern english loanword illustrates the global spread of culinary traditions and the adoption of foreign terms for culturally specific items.

this is a loanword borrowed as a single lexical unit from japanese. it is not productively segmented using english morphemes.
