an argument is a dispute, but dispute doesnt necessarily have to be a verbal argument. while both are technically interchangeable, dispute has a relatively broader meaning. "the capulets and the montagues had a century-long dispute"-here dispute refers to an unresolved disagreement. it can be more heated ( such as a dispute between two nations over territory) or also applied to a small altercation "there was a dispute between the two at a restaurant that ended with them being kicked out" here it means the same as argument. in comparison, argument is not a good choice of word for describing longer disagreements. it is not always appropriate for larger groups, longer periods of time and does not include the other types of disputes (a dispute can be physical such as a physical fight for land. or intellectual- "there has been dispute among scientists as to the origin of the species" here it means a division between the scientific community as the scientist actually do not argue or interact directly with eachother). as in discussing politics: "two nations arguing over land" is less fitting than dispute. in short, arguing generally describes an actual verbal altercation between people, while dispute can be verbal, physical, or in principle, and applied to shorter or longer periods of time (ie a ten-year dispute ), and larger non-individualized subjects for more appropriately (ie company, tribe, family, political group).
