airplane (English)
Where does "airplane" come from?
The English noun 'airplane' is formed as a compound of 'air' and 'plane'[1]. The element 'air' traces back through Middle English 'aire'[6], Old French 'air'[4], and Latin 'āēr'[5] to Ancient Greek 'ἀήρ'[7]. The element 'plane' comes from Latin 'plānum', meaning 'flat surface', introduced in the seventeenth century to distinguish geometrical senses[3]. 'Airplane' itself developed as an alteration of 'aeroplane'[1].
