Etymology
The word 'flightless' is a modern English compound formed by combining the native English noun 'flight' with the adjectival suffix '-less'. 'Flight' itself originates from the Proto-Germanic root fleuganą, meaning "to fly", which evolved through Old English. The suffix '-less' derives from the Old English -lēas, meaning "devoid of", from a root meaning "to lose". The compound's logic is transparently descriptive, directly applying the concept of "without flight" to birds like ostriches, penguins, and kiwis whose wings have become vestigial through evolution, losing the primary avian function.
