Latin. From or by reason of the delay of the debtor. On account of the debtor's delay. Mora signifies not only delay, but undue or culpable delay, which subjects any person guilty of it in its consequences. Thus a debtor's delay in making payment of his debt renders him liable for interest; and undue delay on the part of one of the parties to a contract, will subject him in the consequences, or entitle the other party to resile.
