Arguing or debating is a common way to express disagreement or to discuss a topic. The term 'ARGUE' can be broken down into two four-letter words: SPAR and DEBATE. SPAR is an acronym for 'simulated practice attack and response, ' which is a type of training exercise used in martial arts. DEBATE is a formal discussion between two people or groups, usually with opposing views, in which each side presents its arguments. Together, these two words form the term ARGUE (WITH).
