Etymology

The word 'flightless' is a compound adjective formed from the word 'flight', which originates from Old English 'flyht', meaning the act of flying or the stretch of air through which birds or other flying creatures move. The suffix '-less' comes from Old English '-leas', meaning 'lacking' or 'without'. Together, 'flightless' encapsulates the idea of lacking the ability to fly, which is particularly relevant in the context of certain bird species that have evolved in isolated environments, such as islands, where flight is not necessary for survival. The term has been in use since the early 20th century and has gained importance in discussions about evolution, conservation, and biodiversity, especially concerning species like the dodo and the moa.
