John loves and cares for his tropical fish, and often he adds to his collection.

Is this a simple sentence with compond subject or predicate? Or Compound Sentence with compond subject or compound predicate?

It's a compound sentence. The first clause has a compound predicate.

To analyze whether the sentence "John loves and cares for his tropical fish, and often he adds to his collection" is a simple sentence with a compound subject or predicate, or a compound sentence with a compound subject or compound predicate, we first need to understand these grammatical concepts and how to identify them.

1. Simple sentence: A simple sentence consists of a single independent clause, which means it has a subject and a predicate, and it expresses a complete thought. It does not have any dependent clauses or additional coordinating conjunctions.

2. Compound subject: A compound subject occurs when a sentence has two or more subjects, which are usually joined by coordinating conjunctions like "and," "or," or "but."

3. Compound predicate: A compound predicate occurs when a sentence has two or more predicates, which are usually joined by coordinating conjunctions like "and," "or," or "but."

4. Compound sentence: A compound sentence consists of two or more independent clauses joined together by coordinating conjunctions, semicolons, or transitional words.

Now, let's apply these concepts to the given sentence.

The sentence "John loves and cares for his tropical fish, and often he adds to his collection" can be divided into two independent clauses. The first clause is "John loves and cares for his tropical fish," and the second clause is "often he adds to his collection."

Since these two clauses are joined by the coordinating conjunction "and," it makes the sentence a compound sentence, not a simple sentence. However, each clause has a single subject and a single predicate, so it is not a compound subject or predicate.

To summarize, the sentence "John loves and cares for his tropical fish, and often he adds to his collection" is a compound sentence. It is not a simple sentence with a compound subject or predicate, as each clause consists of a single subject and predicate.
