Forgive
French for for: pour
French for to give: donner
Mangled French thing made from weird English for forgive: pourdonner
Pourdonner sounds liek it could mean to pardon
Pardon is another word for forgive

That's actually similar to the real etymology of "pardon"- "per-" (Latin, "completely") + "donare" (Latin for "give," obviously related to French "donner"). It initially had a slightly different meaning than it does today (more of a synonym to "remit" than "forgive").

Interesting find!

"pourdonner" doesn't mean anything in French though btw.
