'quality-assured' is a modern English compound formed from the noun 'quality' (originating from Latin 'qualitas' via Old French 'qualité') and the past participle 'assured' (from Old French 'asseurer', ultimately from Latin roots related to 'securus' meaning 'safe').

'quality' came into English from Old French 'qualité', which derived from Latin 'qualitas'; 'assured' comes from Old French 'asseurer' (past participle 'assuré') and Middle English forms; the compound 'quality-assured' is a contemporary English formation combining these elements to describe something that has undergone assurance procedures.

The components originally referred separately to 'what kind (quality)' and 'making safe or certain'—together, they evolved into the modern sense 'having been subjected to quality assurance or verified to meet quality standards.'
