Answer:
predicate adjective
Step-by-step explanation:
The day of the big game was *exciting*. The word exciting is an adjective and it has been placed in the predicate of the sentence. Therefore, it says something about the subject : The day of the big game. What does it say about this? It gives qualitative information; it tells what the day of the big game was like for the speaker. The speaker thinks it was exciting, so she has linked the day of the big game with exciting through the verb to be, which is a linking verb. Therefore, exciting functions as a predicate adjective.
