Does the word mortgage come from French language?

Yes, the word "mortgage" does come from the French language. It is derived from the Old French word "mort gage," which literally translates to "dead pledge."

Here's the breakdown:

* Mort: meaning "death"

* Gage: meaning "pledge" or "security"

The concept of a "dead pledge" referred to the fact that if the borrower defaulted on their loan, the property used as collateral became the lender's property permanently, effectively "dying" to the borrower.
