checked

The word 'checked' originates from the Persian 'shāh', meaning 'king', which entered English via Old French and the game of chess. The exclamation "check!" signified a direct threat to the king, leading to the verb 'to check' with the sense of stopping, restraining, or verifying something to halt an error. The addition of the past participle suffix '-ed' transforms the action into a descriptive state. Thus, a 'checked' pattern is one restrained within a grid, and a 'checked' item is one that has undergone the process of verification, both meanings flowing logically from the original concept of control and examination initiated by the chess term.

Structure: check + ed - check: From Old French 'eschec', from Persian 'shāh' (king), via the chess term "check!" (a warning that the king is under attack). In this word, it functions as the core verb root meaning to examine or verify. - ed: From Old English '-ede', '-ode', '-ad', a suffix used to form the past tense and past participle of verbs, and subsequently adjectives from those participles. It indicates a completed action or resulting state.
