adaptor

The word 'adaptor' is a modern agent noun derived from the verb 'adapt'. The verb itself entered English in the early 17th century from the French 'adapter', which originated from the Latin 'adaptare', meaning "to fit to, to adjust". This Latin term is a compound of 'ad-' (to) and 'aptare' (to fit), from 'aptus' (fitted). The suffix '-or', a common agentive suffix in Latin, was appended to form a noun denoting "one who adapts". While its earliest usage referred to a person who modifies a text or work, its most common contemporary meaning—a physical device that enables connection or compatibility—perfectly embodies the core concept of making one thing suitable or fitted to another.
