I heard an expression:
その◯◯が二両のかたに預けてあるのは、彼は知りません。
The intended meaning was "he did not know that ◯◯ has been pawned for 2 ryō". Not a pawn-shop, but given as a collateral to a person who lends money.
I searched all dictionaries I had in hand specifically for a meaning that would fit the case and could not find any.
Did I miss anything in dictionaries or did I just mishear? Is there such a phrase? If so, what would be the etymology, ie. which one of 方, 形, 片, ... would it be and why?
