"For example," "for instance," "in other words," and "to illustrate" fall into the category of transitional words and phrases known as exemplification or illustration transitions. These transitions are used to introduce examples or clarify an idea by providing an illustration that supports the point being made. They help to explain, clarify, or reinforce the writer's ideas by showing how a general statement applies in specific instances. These types of transitions are particularly useful in writing when an author wants to highlight a particular instance or detail to support a broader concept or argument.
