Exemplification is using examples to illustrate an idea or opinion. There are different types of examples including those that illustrate, explain, tell a story, or describe. Examples can be brief or extended. They can come from personal experience, observation, general knowledge, or research. Hypothetical examples can also be used to make a point. Common transitions to introduce examples include "for example", "such as", and "for instance". The most logical order is from least to most emphatic.
