Here are some key points about predicate adjectives:

1. Placement: Predicate adjectives are placed after the linking verb in a sentence and modify the subject.

   • Example:
     • "She is happy,"
     • "The flowers smell fragrant."

2. Linking Verbs: Predicate adjectives are used with linking verbs, such as "be," "become," "seem," "appear," "feel," "look," "sound," "smell," or "taste."

   • Example:
     • "She looks tired,"
     • "The cake tastes delicious."

3. Description or Quality: Predicate adjectives provide additional information or describe the subject by expressing its state, condition, or quality.

   • Example:
     • "The movie was entertaining,"
     • "He seems confident."

4. No Agreement: Predicate adjectives do not change in form to agree with the subject. They remain the same regardless of the subject's number or gender.

   • Example:
     • "She is happy,"
     • "They are happy."

5. Adjective Modification: Predicate adjectives modify the subject and provide information about its attributes, qualities, or states.

   • Example:
     • "The weather is sunny,"
     • "The child appears excited."

6. Subject Complement: Predicate adjectives, along with other subject complements like predicate nouns or predicate pronouns, complete the meaning of a sentence by further describing or identifying the subject.

   • Example:
     • "He is a talented musician,"
     • "She became a doctor."

Predicate adjectives contribute to the overall meaning and description of a sentence by providing information about the subject's attributes, qualities, or states. By using predicate adjectives appropriately, you can enhance your sentences and provide a more vivid and accurate portrayal of the subject.
