homodox comes from Ancient Greek homós ('same') + dóxa ('opinion, belief'), modeled on orthodox and heterodox. The path is chiefly one of transmission: the word passes through the named languages and forms, with each stage preserving part of the modern shape. In present English, the adjective sense is "holding the same opinion or doctrine as another (rare)", so the historical development ends in a clearly identifiable modern dictionary use. The same base also appears in related forms such as orthodox, heterodox, and paradox, and in derivatives such as homodoxy. Its semantic neighborhood includes orthodox, agreeing, concordant, and like-minded, which helps locate the modern sense without adding a separate etymological claim. The named historical forms include Ancient Greek homós and Ancient Greek dóxa.
