Root Explanation

Airworthiest → It is formed from "air" (from Old English "aer", meaning the atmosphere or sky) and "worthy" (from Old English "weorðig", meaning having worth or value) combined with the superlative suffix "-est" (indicating the highest degree). The word "airworthiest" means having the highest worth or value in relation to the air or atmosphere, often used to describe aircraft or flying objects.

Memory Tip

Think of 'air' as the atmosphere and 'worthy' as having value — when something is 'airworthiest', it means it has the highest value in the air.
