hélicoptère (French)

Where does "hélicoptère" come from?

The French noun 'hélicoptère' was coined in 1861 by Gustave de Ponton d'Amécourt as a compound of two Ancient Greek roots[1]. He combined 'ἕλιξ' ('hélix'), meaning 'spiral', with 'πτερόν' ('pterón'), meaning 'wing', to describe an aircraft supported by rotating blades[1]. The first element descends from the Proto-Indo-European root '*welH-', meaning 'to turn'[3]. The second element traces back through Proto-Hellenic '*pterón' to the Proto-Indo-European noun '*péth₂r̥', meaning 'feather'[2], formed from the verbal root '*peth₂-', meaning 'to fly'[4].

• The Proto-Indo-European verbal root behind the wing element is reconstructed with several variant forms, including '*pet-', '*peth₁-', and '*peth₂-'. [2] [4] [5]
