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

'anodic' developed from the coinage 'anode' (formed from Greek 'anōdós') and passed through New Latin/Modern French forms such as 'anodique' before becoming the modern English adjective 'anodic'.

Initially it referred to the Greek idea of an 'upward way' ('anōdós'), but over time it came to mean 'relating to an anode' (the electrode where oxidation or the entry of conventional current occurs) in electrochemistry.
