Final answer:
The word used to join two predicates in a compound predicate is and. A compound predicate shares the same subject and connects multiple actions or states. Other options like However, Now, and Once serve different functions in sentences.
Explanation:
Compound Predicates in English
A compound predicate is formed when two or more predicates share the same subject in a sentence. To connect these predicates, we use a coordinating conjunction. The most common conjunction used for this purpose is and.
For example, consider the sentence:
"The cat slept and played on the couch."
In this case, both slept and played are predicates that share the same subject "the cat," and they are joined by the word and.
The other options provided—However, Now, and Once—are not suitable for joining predicates in this way. Instead, they serve different grammatical purposes. However is a transitional word that contrasts ideas, Now is often used to indicate time, and Once indicates a specific occurrence in the past.
In summary, when forming compound predicates, always remember to use and to effectively join multiple actions or states related to the same subject.
