Compound Sentences vs. Complex Sentences: Know the Difference
By Shumaila Saeed || Published on February 24, 2024
Compound sentences join two independent clauses with a coordinating conjunction, while complex sentences combine an independent clause with one or more dependent clauses.
Key Differences
Compound Sentences are formed by joining two or more independent clauses, each capable of standing alone as a sentence, using coordinating conjunctions like 'and', 'but', or 'or'. They show a relationship between equally important ideas.

Complex Sentences, on the other hand, consist of an independent clause and one or more dependent clauses connected by subordinating conjunctions like 'because', 'since', or 'although'. They highlight a primary idea and additional or subordinate details.

In Compound Sentences, the clauses are joined to show a balance or contrast in ideas. Each clause in a compound sentence has equal importance and can stand alone as a complete sentence.

Complex Sentences are used to emphasize one part of the sentence over the other. The dependent clause in a complex sentence cannot stand alone and is used to provide additional context or detail to the main clause.
