risk-based

The compound adjective 'risk-based' is a modern formation from the core noun 'risk' and the participial adjective 'based'. The word 'risk' entered English in the 17th century from Italian, carrying the sense of hazard or exposure to danger, a concept rooted in maritime trade. The element '-based' derives from the architectural and foundational meaning of 'base', which traces back to the Greek 'basis' (a step, pedestal). When combined, the term literally means "founded upon risk," creating a logical and transparent descriptor for methodologies where the assessment or magnitude of potential danger forms the foundational criterion for action, planning, or regulation.

Structure: risk (noun) + based (adjective suffix) - risk: From Italian 'risco' or 'rischio' (danger, peril), likely from a Vulgar Latin root meaning "that which cuts" or "cliff". - based: From the past participle of the verb 'base', from Old French 'baser' (to found, build), from Latin 'basis' (foundation, pedestal), from Greek 'basis' (a stepping, step, base).
