'arthrodynic' originates from Greek, specifically the elements 'arthron' and 'odunē', where 'arthron' meant 'joint' and 'odunē' meant 'pain'.

'arthrodynic' was formed in New Latin/medical Latin by combining Greek elements (cf. 'arthrodynia' for the noun) and was later adopted into English as the adjective 'arthrodynic'.

Initially the Greek elements meant 'joint' + 'pain'; in English the compound evolved to mean 'relating to or causing joint pain'.
