'axonometry' originates from French, specifically the word 'axonométrie', where 'axon-' (from Greek 'axōn') meant 'axis' and '-metry' (from Greek 'metron') meant 'measure'.

'axonometry' changed from the French word 'axonométrie' and eventually became the modern English word 'axonometry' (adopted into English technical vocabulary in the 19th century).

Initially, it meant 'measurement of axes', but over time it evolved into its current meaning of 'a method of representing 3D objects in 2D by axis-based parallel projection'.
