🔹 What is a Compound-Complex Sentence?

According to the image:

> A compound-complex sentence is a sentence composed of two or more independent clauses joined by a conjunction (like *and*, *but*, *so*), and one or more of those clauses must be a complex sentence—meaning it contains at least one dependent (subordinate) clause.

In simpler terms:
- It has at least two independent clauses (complete thoughts that can stand alone).
- And at least one dependent clause (a clause that cannot stand alone because it starts with a subordinating conjunction like *since*, *because*, *although*, etc.).

So, a compound-complex sentence combines features of:
- Compound sentence: two or more independent clauses.
- Complex sentence: one independent and one dependent clause.

Thus, a compound-complex sentence = compound + complex.

🔹 Example Given in the Image

> "John doesn't like novels since they are lengthy, so he doesn't read them."

Let’s analyze this sentence step-by-step:

#### Step 1: Identify the clauses

1. "John doesn't like novels" → Independent clause (can stand alone).
2. "since they are lengthy" → Dependent clause (starts with *since*, which is a subordinating conjunction; cannot stand alone).
3. "he doesn't read them" → Independent clause (can stand alone).

So we have:
- Two independent clauses: "John doesn't like novels" and "he doesn't read them".
- One dependent clause: "since they are lengthy".

#### Step 2: Check structure
- The two independent clauses are joined by the conjunction "so".
- The dependent clause ("since they are lengthy") modifies the first independent clause.

✔ This fits the definition: two independent clauses + one dependent clause, joined by conjunctions.

Therefore, this is a compound-complex sentence.

🔹 Why Are These Sentences Used?

As stated in the image:
> They are used mainly to express complex thoughts or a sequence of events.

These types of sentences are common in academic writing, literature, and formal communication because they allow writers to show relationships between ideas (e.g., cause and effect, contrast, condition).

✔ Summary: Solution & Explanation

| Element | Description |
|--------|-------------|
| Type of Sentence | Compound-complex |
| Independent Clauses | 1. John doesn't like novels<br>2. He doesn't read them |
| Dependent Clause | Since they are lengthy |
| Conjunctions Used | "since" (subordinating), "so" (coordinating) |
| Structure | [Independent] + [Dependent] + [Independent] |

👉 The sentence shows cause and effect:
- Cause: Novels are lengthy → John doesn’t like them.
- Effect: So, he doesn’t read them.

This demonstrates how compound-complex sentences help express nuanced reasoning.

📌 Final Answer:

The sentence "John doesn't like novels since they are lengthy, so he doesn't read them" is a compound-complex sentence because it contains:
- Two independent clauses ("John doesn't like novels", "he doesn't read them"),
- One dependent clause ("since they are lengthy"),
- Joined by conjunctions ("since" and "so").

It effectively expresses a chain of thought: reason → dislike → consequence.

✔ This matches the definition and purpose of compound-complex sentences as shown in the image.
