saturday

The word Saturday has its origins in the Old English Sæternesdæg, a translation of the Latin diēs Sāturnī, meaning "day of Saturn." This follows the ancient Roman practice of naming a day after a celestial body and its associated god, in this case, the planet Saturn and the Roman god of agriculture and time. The name was adopted into the Germanic languages, with the Old English form eventually simplifying in spelling and pronunciation to become the modern 'Saturday.' Thus, the word preserves a direct link to classical astronomy and mythology, now fixed as a standard term in the modern calendar.

This word is a simplex form. It is a loanword from Old English Sæternesdæg, meaning "day of Saturn." The modern spelling 'Saturday' is a direct, unsegmentable continuation of this compound.
