Here's how it works:
* The unknown word is often followed by words like "is," "means," "or," "that is," or "in other words."
* The definition of the unknown word is provided immediately after these signal words.
Here's an example:
"The omnivore, *meaning an animal that eats both plants and animals*, is a common sight in many ecosystems."
In this sentence, the word "omnivore" is directly defined as "an animal that eats both plants and animals." This is a clear example of a definition clue.
