hard-cooked

The compound adjective "hard-cooked" is a transparent and descriptive formation from two native English elements. "Hard," with its Proto-Germanic origin in harduz, conveys the concept of solidity and unyielding firmness. "Cooked" derives from the Latin verb 'coquere', which entered English via Old French and broadly means to prepare or ripen by the application of heat. The logic of the word is entirely literal: it specifies a method of cooking (applying heat) that results in a specific, firm texture, primarily used to distinguish eggs boiled to a completely solid state from those that are soft-boiled. This compounding follows a common English pattern of combining an adjective with a past participle to create a precise descriptive term.

Structure: hard (firm) + cooked (prepared with heat) - hard: From Old English 'heard', meaning solid, firm, resistant. In this compound, it functions as an intensifier describing the degree of cooking. - cooked: Past participle of the verb 'cook', from Latin 'coquere', meaning to prepare food with heat. It functions as the core verbal element in the compound adjective.
