The example essay focuses on a subject which a writer develops and amplifies using examples. The example essay is generally written for the purpose of informing the reader by piecing together information derived from various sources, which may include but are not limited to a writer's own experiences. Personal experiences and observations are a valid form of information and can be used effectively to support a writer's ideas and opinions. However, the focus must stay on the subject with the writer subordinated to the subject.
Examples are indispensable in learning.
It's almost impossible to understand general concepts until one is given specific examples. It is hard to think of a subject that examples will not clarify. Explaining through examples is one of the most effective ways to support controlling ideas. Like telling a story, giving examples seems to be a natural way of proving a point to someone else because that is usually the way one arrives at conclusions. Through certain experiences, events, or research witnessed or conducted, one forms a generalization.
