The term 'FIGHTING ENDER' can be broken down into two crossword solutions: TRUCE (5 letters) and TREATY (6 letters). A TRUCE is an agreement between two or more parties to cease hostilities for a certain period of time. It is usually a temporary solution to a conflict, and does not necessarily involve a formal agreement. A TREATY, on the other hand, is a formal agreement between two or more parties that is legally binding. Treaties are often used to settle disputes between nations and are usually more permanent than truces.
