Supporting Details

While the main idea is the overall premise of a story, supporting details provide evidence and backing for the main point. In order to show that a main idea is correct, or valid, the author needs to add details that prove their point. All texts contain details, but they are only classified as supporting details when they serve to reinforce some larger point. Supporting details are most commonly found in informative and persuasive texts. In some cases, they will be clearly indicated with words like for example or for instance, or they will be enumerated with words like first, second, and last. However, they may not be indicated with special words. As a reader, it is important to consider whether the author’s supporting details really back up his or her main point. Supporting details can be factual and correct but still not relevant to the author’s point. Conversely, supporting details can seem pertinent but be ineffective because they are based on opinion or assertions that cannot be proven.
