Difference Between Compound & Complex Sentences

Understanding different types of sentences and their distinctions can enhance writing and make it more engaging for readers. Simple, compound, complex, and compound-complex sentences each have their own characteristics. It is common for students to confuse compound and complex sentences, so this article aims to clarify the differences between them.

Key Takeaways

  • Compound sentences consist of two independent clauses joined together with a coordinator, such as “but,” “for,” “and,” “yet,” or “nor.”
  • Complex sentences contain an independent clause and one or more dependent clauses, often reflecting relationships or conveying ideas.
  • The main difference between compound and complex sentences lies in the number of independent and dependent clauses: compound sentences have at least two independent clauses, while complex sentences have one independent clause and at least one dependent clause.

Compound Sentences

It is helpful to first understand simple sentences, also known as independent clauses, which express a single thought and contain a subject and a verb. A compound sentence is formed by combining two independent clauses with a coordinator, which requires placing a comma before the coordinator. Coordinators can include words like “but,” “for,” “and,” “yet,” or “nor.” For example:

Simple sentences:
– I was learning Mexican.
– My friend was learning Spanish.

Compound sentence:
– I was learning Mexican, but my friend was learning Spanish.

Complex Sentences

A complex sentence contains an independent clause and one or more dependent clauses. The key feature of a complex sentence is the relationship or idea conveyed through linking devices. For example:

Complex sentence:
– The puppy barked because it was lonely.

In this sentence, the independent clause is “The puppy barked,” and the dependent clause is “it was lonely.” The linking device “because” indicates the reason behind the puppy’s barking. The dependent clause in a complex sentence is also called an adjective clause.

Another example:
– John was excited to get his new shoes that he purchased from the internet.

In summary, compound sentences have two independent clauses joined by a coordinator, while complex sentences have an independent clause and one or more dependent clauses. The main distinction between the two lies in the number of independent and dependent clauses, with compound sentences having at least two independent clauses and complex sentences having one independent clause and at least one dependent clause.
