Etymology
The word 'airworthiness' is a modern technical compound, constructed in English from native Germanic elements to fulfill a specific need in aviation. Its core, 'airworthy', is a transparent 20th-century formation, directly combining 'air' (the medium of flight) with 'worthy' (fit or suitable) to mean "fit for flight". The suffix '-ness', an ancient and productive Germanic nominalizer, is then appended to convert this descriptive adjective into an abstract noun denoting the essential condition or certified standard of being safe to operate in the air. Thus, the term's logic is entirely compositional, moving from the literal "fitness for the air" to the official, regulated quality required for an aircraft's certification.
Analysis

- ness: A noun-forming suffix from Old English '-nes(s)', '-nis(s)', used to denote a state, condition, or quality.
