PLEASE HELP ASAP A subject complement is a noun, a pronoun, or an adjective that appears after a linking verb and tells something about the subject. Three types of subject complements are predicate nouns, predicate pronouns, and predicate adjectives.
• A predicate noun is a noun that identifies or renames the subject of the sentence.
• A predicate pronoun is a pronoun that identifies or renames the subject of the sentence.
• A predicate adjective is an adjective that describes the subject of the sentence.
A. DIRECTIONS: Underline the subject complement in each sentence. Then, identify it by writing PN for predicate noun, PP for predicate pronoun, or PA for predicate adjective.
1. Clara’s uncle was he.
2. Her uncle’s experiments were strange-smelling liquids.
3. His moustache was thin.
4. Nicolás is Marcos’s great-nephew.
5. Marcos once became a clairvoyant.
6. The person most affected by his death is she.

B. DIRECTIONS: In each sentence, circle the linking verb and underline the subject complement.
1. The instrument is a high-pitched noisemaker.
2. The woman standing in the window was she.
3. Marcos’s shipment was enormous boxes.
4. The man with the adventurous spirit is he.
5. Marcos became ill and tried to return home.

Explanation:     Read these examples:

       Brandon is a gifted athlete.

       Brandon = subject; is = linking verb; athlete = noun as subject complement.

       It was he who caught the winning touchdown Friday night.

       It = subject; was = linking verb; he = pronoun as subject complement.

       Brandon becomes embarrassed when people compliment his skill.

       Brandon = subject; becomes = linking verb; embarrassed = adjective as subject complement.

   Then you have a list of verbs that can be linking or action: appear, feel, grow, look, prove, remain, smell, sound, taste, and turn.

   If you can substitute any of the verbs on this second list with an equal sign (  =  ) and the sentence still makes sense, the verb is almost always linking.

       Brandon's face will turn red.

       Face = subject; will turn = linking verb; red = adjective as subject complement. (Will turn is a linking verb because if you substitute an equal sign, the sentence still makes sense.)

Do not confuse subject complements with direct objects.

   Only linking verbs can have subject complements. If you have an action verb, then the word that answers the question what? or who? after the Subject + Verb is a direct object.

       When Michelle woke up this morning, she felt sick.

       She = subject; felt = linking verb; sick = subject complement. (Felt is a linking verb because if you substitute this felt with an equal sign, the sentence still makes sense.)

       Michelle felt her forehead but did not detect a temperature.

       Michelle = subject; felt = action verb. She felt what? Forehead = direct object. (Felt is an action verb because if you substitute this felt with an equal sign, the sentence does not make sense.)
