the compound adjective 'tomato-based' is a modern culinary formation, combining the new world ingredient 'tomato' with the established english participial suffix '-based'. the word 'tomato' entered english via spanish colonial contact, tracing back to the nahuatl word 'tomatl', which referred broadly to a class of juicy, swollen fruits. the second element, 'based', derives from the latin and greek concept of a foundation or support. when combined, the term literally means "having tomatoes as its foundation," a logical and transparent description for sauces, soups, or dishes where tomato provides the fundamental character and flavor profile. this pattern of [ingredient]-based is highly productive in english for describing the primary component of a mixture.

Structure: tomato (the fruit) + based (having as a foundation) tomato: from spanish 'tomate', from nahuatl 'tomatl' (meaning the swelling fruit, the tomatillo). functions as the noun root specifying the primary ingredient. based: from the verb 'base' (to found or establish) + the past participle suffix '-ed', forming a participial adjective. 'base' originates from latin 'basis' (foundation, pedestal), from greek 'basis' (a stepping, a step, that on which one stands).
