Question

select the words that make up the complete predicate.
wayne will elaborate on his idea later.
submit

Explanation:

In a sentence, the complete predicate includes the verb and all the words that tell what the subject does or is. The subject here is "Wayne". The verb phrase is "will elaborate", and the rest of the words that complete the action description are "on his idea later". So the complete predicate is "will elaborate on his idea later".

Answer:

will elaborate on his idea later
