Punctuation in Compound Complex Sentences: Practice Exercises

Punctuation in Compound-Complex Sentence: A compound-complex sentence is formed when a compound and a complex sentence are fused. After combining these two, we form a new category of sentences. These are made up of at least two independent clauses and dependent clauses. Today we will learn how you can do punctuation in compound and complex sentences through the help of examples and exercises henceforth.

What are Compound Sentences?

A compound sentence joins two independent clauses together, usually with the help of a coordinating conjunction such as and/or but. It works best when you want to combine two or more independent but connected sentences into a single cohesive sentence. Take a look at these examples to get a better understanding.

• Although she was tired, she decided to go for a run in the park.
• After the rain stopped, the sun emerged from behind the clouds.

What are Complex Sentences?

A complicated sentence consists of a main and subordinate clause and a subordinating conjunction that joins them. Interestingly, subordinating conjunctions are frequently used in academic writing and are a great way to show complex links between ideas, whereas a subordinate clause cannot stand alone as a sentence; it is an incomplete sentence.

Using a comma and a conjunctive adverb (such as “however”, “therefore”, “moreover”, “nevertheless”):
