Compound Sentences vs. Complex Sentences: What's the Difference?
Edited by Huma Saeed || By Sumera Saeed || Updated on October 25, 2023
Compound sentences combine two independent clauses using a coordinating conjunction; complex sentences join an independent clause with one or more dependent clauses.
Key Differences
Compound sentences and complex sentences are both integral structures in English grammar, aiding in the conveyance of nuanced ideas. Compound sentences essentially stitch together two independent clauses. These independent clauses can stand alone, but when joined by coordinating conjunctions like 'and', 'but', or 'or', they form a compound sentence.

Complex sentences, on the other hand, involve an independent clause and at least one dependent clause. The dependent clause cannot stand on its own as it requires the main clause for context. Subordinating conjunctions such as 'because', 'although', or 'when' often introduce these dependent clauses.

One can identify compound sentences through the presence of coordinating conjunctions or semicolons. For instance, "I wanted to play tennis, but it started to rain." Here, 'but' acts as the bridge between two separate thoughts. Complex sentences typically exhibit a shift in focus between the main idea and the additional information. An example would be, "I'll go to the store if I have enough money."

In terms of function, compound sentences offer balance and equilibrium between equally important ideas. Complex sentences, conversely, prioritize one idea over the other, providing depth and layering to the main thought. These sentence structures enhance textual coherence, allowing writers to express multifaceted viewpoints with clarity.
