Here's why:
* Linking verbs connect the subject of a sentence to a word or phrase that renames or describes the subject. Common linking verbs include "be," "seem," "appear," "become," "feel," "look," "sound," "smell," and "taste."
* Predicate adjectives are adjectives that follow a linking verb and describe the subject of the sentence.
Example:
* The sky is blue.
* "is" is the linking verb
* "blue" is the predicate adjective, describing the subject "sky"
Here's another example:
* The music sounds beautiful.
* "sounds" is the linking verb
* "beautiful" is the predicate adjective, describing the subject "music"
Key takeaway: Predicate adjectives are essential for describing the subject of a sentence when a linking verb is used.
