Exemplification

When you want to understand a general concept or an abstract idea, you probably ask for an example. When you  want to explain an idea, you probably provide example as 

strategy to make you thinking clear. Exemplification is simply a way that writers  and speaker use to explain things so that reader and listeners can better understand the topic  being  discussed. We use examples to support  our ideas. The use of examples help  us to make general ideas. A good writer uses enough examples which enable us to grab his/her idea easily.

We use example to: 

1) Explain and clarify 

2) Add interest 

3) Persuade: Convince

4) Test your thesis.
