What is a Compound-Complex sentence?
The three main types of sentences based on clause structure are simple compound and complex sentences. The fourth sentence type, the compound-complex sentence is made by combining elements of compound sentence and complex sentence.
It is the most fancy and sophisticated type of sentence in English grammar.
Complexity of the sentence is high in terms of structure compared to other sentences like simple, compound and complex sentence.
In other words we can say a compound-complex sentence is a combination of two or more sentences joined by a conjunction in which one must be a complex sentence.
Let’s understand the structure of compound complex sentence.
Compound Sentence: Independent clauses
Complex Sentence: 1 Independent clause + Dependent(s)
Compound –Complex Sentence: Independent clauses + Dependent clauses
So basically these types of sentences have one compound sentence and one complex sentence in it.
Let’s take some examples
- After the rained stopped, I went outside and saw the rainbow.
Here we have combination of two kinds of sentences.
After the rained stopped, I went outside: Complex Sentence
I went outside and saw the rainbow: Compound Sentence
- People who read comics rarely read novels; they are often find books so difficult.
Who read comics: Dependent clause
People rarely read novels: Independent clause
They often find books difficult: Independent clause
3.Tom goes for football classes and Jack goes for cricket, but Gary is not interested in sports.
Tom goes for football classes: Independent clause
but Hary is not interested in sports: Dependent clause
and Jack goes for cricket: Dependent clause
Tom goes for football classes and Jack goes for cricket: Compound sentence
Tom goes for football classes: Simple Sentence
Jack goes for cricket but Hary is not interested in sports: compound sentence
4. While it was raining, John went to shop and bought his breakfast.
While it was raining: Dependent clause
and bought his breakfast: Dependent clause
John went to shop: Independent clause
While it was raining, John went to shop: Complex Sentence
John went to shop and bought his breakfast: Compound Sentence
John went to shop: Simple Sentence
Let’s see complex compound sentence structure in a different form.
Independent clause + Coordinating Conjunction + Complex Sentence
1.He loves parties, but he can’t attend today as he is sick.
He loves parties: Independent clause
But: Coordinating Conjunction
he can’t attend today as he is sick: Complex Sentence
We can combine several dependent clauses or independent clauses in different ways to form a complex-compound sentence but we should have correct punctuation and right linking words in place.
Complex Sentence + Coordinating Conjunction + Independent clause
2.When my roomies come home from work, Parth cleans the vessels and Rina cooks dinner.
In above sentence the complex- compound sentence structure changes.
When my roomies come home from work, Parth cleans the vessels: Complex Sentence
And: Coordinating Conjunction
Rina cooks dinner: Independent clause
We can also say:
Parth cleans the vessels and Rina cooks dinner – Compound Sentence
So here we can make Simple sentence, compound sentence and a complex sentence from a complex- compound sentence like than from a simple sentence, a compound sentence and a complex sentence we can form a complex compound sentence.
