'anodization' originates from English, specifically the word 'anodize' combined with the suffix '-ation', where 'anodize' is built from 'anode' (from Greek 'anodos').

'anodization' developed from the verb 'anodize' (formed in the 19th century from 'anode' + '-ize'); 'anode' itself comes from Greek 'anodos' ('upward way'), and the noun form later gained the suffix '-ation' to denote the process.

Initially associated generally with actions relating to anodes or making an anode, it came to mean specifically the electrochemical process of forming an oxide coating on a metal surface.
