Morphology

Jupiter + Fidius

Although 'Jupiter' is transparent as the Roman god, the second element 'Fidius' is a Latin epithet (from fides 'faith') not recognizable to a B1 English learner and not an English lexical item. The epithet's meaning (guarantor of good faith/oaths) depends on cultural and historical knowledge rather than composition of familiar English words, so it is opaque to learners.

Etymology

Jupiter Fidius joins Jupiter and Fidius, where Fidius points to 'faith' or 'trust' and people pictured the god watching over oaths and promises. So, Jupiter Fidius was the god Romans called on to make sure promises were kept.
