A ceasefire is an agreement between two or more parties to stop fighting or other hostile activities. The term 'ceasefire' can be broken down into three parts: LULL (4 letters), ARMISTICE (9 letters), and TRUCE (5 letters). A LULL is a temporary pause in hostilities, an ARMISTICE is a formal agreement between two or more parties to end hostilities, and a TRUCE is a period of time during which hostilities are suspended. All three terms refer to the same concept of a ceasefire.
