Welcome to this comprehensive guide on complex sentences in English. Whether you’re a beginner, an intermediate learner, or a seasoned writer, mastering the art of constructing and using complex sentences can elevate your communication skills and make your writing more nuanced and engaging.
1. Overview
- Definition: A complex sentence contains one or more subordinate clauses (dependent clauses) alongside a main clause. These clauses allow you to convey nuanced information, relationships, and conditions within a single statement.
- Purpose: Complex sentences enable the expression of intricate ideas, such as conditional actions, reasons, and additional details about subjects or objects.
2. Types of Subordinate Clauses
2.1. Adverbial Clauses
- Express: time, place, manner, reason, condition, or consequence.
-
When the rain stops, we will go out.
2.2. Relative (or Dependent) Clauses
- Provide additional information about a noun or pronoun.
-
The book that I bought yesterday is on sale.
2.3. Conditional Clauses
- Express conditions and outcomes.
-
If you finish the homework, you can play.
2.4. Noun Clauses
- Function as a noun within the sentence.
-
What is your favorite color?
3. Structure of Complex Sentences

3.2. Subordinate Clauses

4. Connecting Subordinate Clauses
4.1. Punctuation
- Use commas to separate clauses when they are not joined by a conjunction.
