I'm sorry, but the debate and topic have nothing to do with your word epistemology. Most non-retarded people use the word "mortgage" to mean something besides "death grip." I'm sorry that you are so hung up on the root history of words which comprise our language, to the point you can't understand the language, but I don't have time to indulge retards here. We don't speak in dissection of words, it's not how human beings communicate. In order to have dialogue, we have to understand the language we're speaking to each other, and since you don't seem to comprehend how language works, it doesn't appear possible to have a dialogue with you.

mortgage
1.the charging of real (or personal) property by a debtor to a creditor as security for a debt (especially one incurred by the purchase of the property), on the condition that it shall be returned on payment of the debt within a certain period.
2. a deed effecting the conditions of a mortgage.
3. a loan obtained through the conveyance of property as security.
4. convey (a property) to a creditor as security on a loan.
5. expose to future risk or constraint for the sake of immediate advantage.
As we see, the word simply doesn't mean, "death grip."
Now, do you want to get back on topic, or shall we continue to ridicule your runetardation?
