'axonometric' originates from Greek, specifically the elements 'axōn' meaning 'axis' and 'metron' meaning 'measure', combined with the adjectival suffix '-ic' via New/Modern Latin formation ('axonometricus').

'axonometric' developed from Greek elements into New Latin/Modern Latin forms (for example 'axonometricus'), passed into European technical vocabulary (e.g. French 'axonométrique') and was adopted into English as 'axonometric'.

Initially it carried the sense of 'measuring or relating to an axis' from its Greek roots; over time it came to be used specifically for the drawing/projection technique known as axonometric projection.
