Etymology
The name Jupiter originates from the Proto-Indo-European compound dyeu-pəter, composed of the root dyeu- meaning "to shine" or "sky" (also the source of 'Zeus', 'deity', and 'Tuesday') and pəter- meaning "father". In Latin, this evolved into 'Iuppiter' or 'Iupiter', the name of the king of the gods, associated with the sky, lightning, and law. The planet, visible as a bright, shining object in the night sky, was named after this powerful deity by ancient astronomers, thereby transferring the mythological association of supreme authority and celestial brilliance to the largest planetary body.
Analysis
The word 'Jupiter' is a simplex loanword from Latin. It is the name of the Roman sky-god, derived from the Old Latin vocative compound Dieu-pater, meaning "Father Jove" or "Sky Father."
