Simple Sentences:
Simple sentences are the most basic type of sentence structure. They consist of a single independent clause, which means they have only one subject and one verb. Simple sentences convey a complete thought or idea and can stand alone as a sentence.

Example:
- John went to the store.

Compound Sentences:
Compound sentences are formed by joining two or more simple sentences with coordinating conjunctions (such as "and," "but," "or," "so") or with a semicolon. The coordinating conjunctions connect the two independent clauses, making them equal in importance.

Example:
- I went to the store, and John went to the park.
- I wanted to go to the party, but I had to study for my exam.

Complex Sentences:
Complex sentences are made up of one independent clause and one or more dependent clauses. A dependent clause cannot stand alone as a sentence and is dependent on the independent clause for meaning. Complex sentences often use subordinating conjunctions (such as "because," "although," "since") to connect the clauses.

Example:
- Although it was raining, we decided to go for a walk.
- Because I studied hard, I got an A on the test.

Explanation:
- Simple sentences are the most straightforward type of sentence structure, consisting of a single independent clause.
- Compound sentences combine two or more independent clauses using coordinating conjunctions or a semicolon.
- Complex sentences include one independent clause and one or more dependent clauses, which rely on the independent clause for meaning.
- Simple sentences convey a complete thought, while compound and complex sentences provide additional information or show relationships between ideas.
- Compound and complex sentences allow for more variety and complexity in sentence structure, making writing more engaging and nuanced.
- Understanding the distinctions between these sentence types is important for effective communication and writing.
