Why does the di come before for Sunday in french?

It's not that "di" comes before "for" in Sunday in French, but rather that the French word for Sunday is "dimanche."

Here's the breakdown:

* "Dimanche" is the French word for Sunday. It comes from the Latin "dies Dominica," meaning "Lord's day."

* "Di" is not a separate word, but part of "dimanche".

* "For" does not appear in the French word for Sunday.

The word order in French is different than English, and the word "dimanche" is a single, indivisible unit.
