Complex Sentences

In the realm of grammar and language, complex sentences play a crucial role in conveying intricate ideas and relationships between different parts of a sentence. Understanding how to form complex sentences and the various structures they can take is essential for effective communication and writing.

Analogy of Definition

What are Complex Sentences?

A complex sentence is a sentence that contains an independent clause and at least one dependent clause. An independent clause is a complete sentence that can stand alone, while a dependent clause relies on the independent clause for its meaning. Complex sentences are formed by combining these clauses using subordinating conjunctions or relative clauses.


Forming Complex Sentences

There are several ways to form complex sentences, each involving the use of conjunctions or relative clauses. By understanding these methods, you can create sentences that express complex ideas and relationships between different parts of the sentence.

Complex Sentences with a Subordinating Conjunction in the Beginning

One way to form a complex sentence is by using a subordinating conjunction at the beginning of the dependent clause. For example:
– Independent Clause: I enjoy reading books.
– Dependent Clause: Although I have many books to read.
– Combined: Although I have many books to read, I enjoy reading books.

Complex Sentences with a Subordinating Conjunction in the Middle

Another method is to place the subordinating conjunction in the middle of the sentence, connecting the independent and dependent clauses. For example:
– Independent Clause: She went to the store.
– Dependent Clause: where she bought some groceries.
– Combined: She went to the store where she bought some groceries.

Complex Sentences with a Relative Clause as the Dependent Clause

Using a relative clause as the dependent clause is another way to form a complex sentence. For example:
– Independent Clause: The book is on the table.
– Dependent Clause: that I was reading yesterday.
– Combined: The book that I was reading yesterday is on the table.


Forming Complex Sentences Example

Let’s take a look at an example of how to form complex sentences using the methods mentioned above.

– Independent Clause: The students completed their project.
– Dependent Clause: after they received guidance from their teacher.
– Combined: The students completed their project after they received guidance from their teacher.


Tips and Tricks

1. Start with Simple Sentences

Tip: Begin with two or more simple sentences that you want to connect.

2.Use Subordinating Conjunctions

Tip: Introduce a dependent clause with subordinating conjunctions like “although,” “because,” “while,” “since,” etc.

3.Combine with Relative Pronouns

Tip: Incorporate relative pronouns like “who,” “which,” “that,” etc., to join two sentences or clauses.

4.Vary Sentence Structure

Tip: Experiment with different sentence structures to add complexity. For example, use a combination of independent and dependent clauses.

5. Avoid Run-On Sentences

Tip: Be mindful not to create run-on sentences by joining too many ideas without appropriate punctuation or conjunctions.

To form complex sentences using subordinating conjunctions, connect the independent and dependent clauses with words such as although, because, when, while, if, and since. These conjunctions create a relationship between the clauses, making the sentence complex.
