A serious fight is a conflict between two or more people that involves physical violence. The term can be broken down into two words: WAR (3 letters) and BRAWL (5 letters). WAR is an organized and often prolonged conflict that is carried out by states or nations, while BRAWL is a noisy, violent fight between two or more people. Together, these two words form the term SERIOUS FIGHT, which describes a physical altercation between two or more people that is more intense than a simple argument.
