'quality-checked' originates from Modern English, formed by combining the noun 'quality' and the verb 'check' (past participle 'checked'). 'quality' comes from Old French 'qualité', from Latin 'qualitas' (from 'qualis' meaning 'of what sort'); 'check' (verb) comes via Old French 'eschec' / 'eschequier' and Medieval Latin 'scaccus' related to the game of chess, later extended in sense to mean 'stop, control' and then 'examine or verify'.

'quality' originates from Old French 'qualité' and Latin 'qualitas'; 'check' developed from Medieval Latin 'scaccus' → Old French 'eschec' → Middle English 'check'. In Modern English the compound 'quality-check' (verb/noun) emerged by combining these elements, and the past participle form became 'quality-checked'.

Initially, the separate elements meant 'sort/kind' ('quality') and a notion related to 'a halt or control' (from the chess term that became 'check'); over time, 'check' acquired the sense 'to examine or verify,' so the compound came to mean 'to examine for quality.'
