'anodic' originates from Greek, specifically the word 'anodos', where 'ano-' meant 'up' and 'hodos' meant 'road, way'.

'anodic' changed from Greek 'anodos' to New Latin/English 'anode' (coined in the late 18th century) and later formed the adjective 'anodic' with the suffix '-ic'.

Initially related to the notion of 'an upward way' (from Greek), but over time it came to mean 'pertaining to the anode' and specifically to processes of oxidation at that electrode.
