'autoxidizability' originates from English, specifically formed from the combination of 'autoxidize' and the suffix '-ability', where 'auto-' comes from Greek 'autos' meaning 'self' and 'oxidize' relates to 'oxygen' (from French/Latin roots) meaning 'to form oxides'.

'autoxidizability' developed from the verb 'autoxidize' (a formation combining 'auto-' + 'oxidize'). 'Oxidize' traces back through Modern French/Latin forms related to 'oxygen' and ultimately to Greek elements meaning 'sharp'/'acid-forming'; the compound term was extended by the English suffix '-ability' to denote the property or capacity.

Initially the components conveyed 'self' + 'becoming an oxide'; over time the combined term came to mean the general susceptibility or capacity of a substance to undergo autoxidation (the current meaning).
