Complex Sentences - Definition, Structure and Examples

Complex Sentences are an important component of correct English grammar after completing compound sentences one should start with complex sentences. When compared to simple sentences, they enable us to transmit a greater amount of information and express our ideas in a more nuanced manner. In this reference, we will investigate what a complicated sentence is, its structure, types, examples, how to build one, and typical mistakes, and discover how it functions when it comes to grammar.

What is a Complex sentence?

A sentence is considered to be complicated when it has at least one independent clause, sometimes referred to as the main clause, along with one or more dependent clauses, often referred to as subordinate clauses. A comma is used to connect the clauses in a sentence whenever the dependent clause comes first in the sentence. In other types of complicated sentences, the independent and dependent clauses are connected by subordinating conjunctions such as "when," "how," and "if."

Examples of Complex sentence

• Although it was too hot outside, he was wearing a coat.
• When she arrived at the airport, the plane had already taken off.
• Most people will buy the car that has the highest gas mileage.

• We have been very happy since he left.
• The cat jumped on the tree while I was sitting in the park.
• Helen is very sick today and we will make her see the doctor before she gets worse.

How to Identify a Complex Sentence?

Although it may be challenging to comprehend a conditional statement, in general, complicated sentences adhere to straightforward grammatical principles. If you employ the appropriate subordinating conjunction in a complicated sentence, the only thing you need to worry about is the commas.

• The clause that comes first in a sentence determines whether or not a comma should be used:
• If the dependent clause comes first in the sentence, a comma needs to go just before the independent clause.
• In the event that the independent clause comes first, there is no requirement for a comma to be used.

Structure of Complex Sentence

• A complicated sentence is one that consists of at least one independent phrase and one or more dependent clauses, all of which are connected to one another by the use of subordinating conjunctions, relative pronouns, as well as punctuation.
• It is possible to place the independent clause at the beginning of the sentence, in the middle of the sentence, or perhaps at the end of the sentence. Complex sentences do not adhere to any predetermined pattern because of this reason.
• Complex sentences are constructed by focusing the sentence on the independent clause, often known as the "main clause," and then adding dependent clauses to the phrase in order to add supplementary information that extends on the information provided by the main clause.
