Airworthier → It is formed from "air" (from Old French *air*, meaning the atmosphere or sky) and "worthy" (from Old English *weorðe*, meaning having worth or value) combined with the comparative suffix "-ier" (indicating more). The word "airworthier" means having more worth or value in relation to the air or atmosphere.
Think of 'air' as the atmosphere and 'worthy' as having value — so 'airworthier' means something that has more value in the context of the air.
