In the final of our day-of-the-week comparisons, we have Sunday.
In the Latin languages, it is domingo, or a variation of it. These all come from the Latin for God — Deus. Sunday, after all, is the traditional Christian day of prayer and worship for God. It is literally God’s Day.
In the Germanic tradition — well, in the ancient German pantheon of nature Gods, the main God was the Sun himself. Our Sunday is quite literally “sun” — “day”: the day of the sun. The parallel thus continues!
