milk-based

the compound adjective 'milk-based' is a modern english formation, combining two elements of distinct origins. the first element, 'milk', descends from the old english 'meoluc', a term of germanic lineage, ultimately from the proto-indo-european root melg-, meaning "to rub off" or "to stroke," referencing the act of milking. the second element, 'based', originates from the latin 'basis', meaning "foundation" or "pedestal," which entered english via old french. the logic of the compound is transparently descriptive: it denotes a substance or product whose fundamental composition or primary ingredient is milk, directly linking the foundational component ('milk') to the concept of being formed from it ('based').

Structure: milk (substance) + based (formed from) milk (old english 'meoluc', 'milc', a noun denoting the white fluid produced by female mammals); based (from the verb 'base', meaning to form, make, or derive from a foundation, with the suffix '-ed' forming a participial adjective).
