Primary, Secondary, and Tertiary Sources Sources of information or evidence are often categorized as primary, secondary, or tertiary material. These classifications are based on the originality of the material and the proximity of the source or origin.
I believe this is the definition for example clues.
Explanation:
We often hear of context clues, but authors can also employ example clues. Example clues can be found when authors give an example that facilitates the understanding of an unfamiliar word by the reader. A regular context clue would not offer an example. Example clues tend to use the terms "such as", "for instance", "for example", "to illustrate", among others.
