Predicate Adjective
* A predicate adjective modifies (describes) the subject of a sentence.
* It follows a linking verb, such as "be," "seem," "become," "feel," etc.
Example:
* The fruit is squashy.
* "Squashy" is the predicate adjective because it describes the subject "fruit" and follows the linking verb "is."
