What is the definition of a compound-complex sentence?

A compound-complex sentence is defined as having two or more independent clauses along with one or more dependent clauses. This structure allows for a more complex sentence that can convey richer information or more nuanced thoughts.

For example, in the sentence "Although I was tired, I decided to go for a run, and I felt great afterwards," there are two independent clauses ("I decided to go for a run" and "I felt great afterwards") and one dependent clause ("Although I was tired"). This combination enables the writer to express multiple ideas and their relationships clearly and effectively.

The idea of having just independent clauses, or only one independent clause without any dependent clauses, does not meet the criteria for a compound-complex sentence. Therefore, recognizing the need for at least one dependent clause alongside multiple independent clauses is crucial for defining this particular sentence structure.
