Outlines are primarily based upon the principle of coordination and subordination.
The principle of coordination refers to the equal importance of ideas or topics within a given level of the outline. This means that each idea or topic should be given the same level of importance as the others at the same level.
The principle of subordination refers to the hierarchical relationship between the different levels of the outline. This means that the main ideas or topics should be at the highest level of the outline, with supporting ideas or details listed at lower levels.
An outline that is properly coordinated and subordinated will help to organize and clarify the writer's thoughts, making it easier to create a well-structured and effective piece of writing.
