Lesson Content/Board Summary
Complex Sentence: Identification And Use Of Complex Sentences In Context
What is a Complex Sentence?
A complex sentence is a sentence that contains one independent clause and at least one dependent (subordinate) clause. The clauses are joined by a subordinating conjunction or a relative pronoun.
Components of a Complex Sentence
A complex sentence is made up of two main parts:
- Independent Clause: This is a complete thought that can stand alone as a simple sentence. It has a subject and a verb.
- Dependent (Subordinate) Clause: This is an incomplete thought that cannot stand alone as a sentence. It also has a subject and a verb, but it begins with a subordinating conjunction or a relative pronoun, making it dependent on the independent clause for its full meaning.
Subordinating Conjunctions
Subordinating conjunctions connect a dependent clause to an independent clause. They indicate the relationship between the two clauses, such as time, cause, condition, or contrast.
Common subordinating conjunctions include:
- Time: after, as, as long as, as soon as, before, by the time, once, since, until, when, whenever, while
- Cause/Reason: as, because, now that, since
- Condition: if, only if, unless, provided that, assuming that, even if
- Contrast/Concession: although, even though, though, whereas, while
- Purpose: in order that, so that
- Place: where, wherever
- Manner: as, as if, as though
Relative Pronouns
Relative pronouns can also introduce dependent clauses (specifically, adjective clauses) in complex sentences.
Common relative pronouns include:
- who
- whom
- whose
- which
- that
Structure of Complex Sentences
A complex sentence can be structured in two main ways:
- Dependent Clause + Independent Clause: When the dependent clause comes first, it is usually followed by a comma.
Example: Because he was tired, he went to bed early.
- Independent Clause + Dependent Clause: When the independent clause comes first, a comma is usually not needed before the dependent clause.
Example: He went to bed early because he was tired.
Identification of Complex Sentences
To identify a complex sentence, look for:
- One clause that can stand alone (independent clause).
- At least one clause that cannot stand alone and begins with a subordinating conjunction or relative pronoun (dependent clause).
Examples for identification:
- Although it was raining, we still went for a walk. (Dependent clause first)
- I will call you when I arrive home. (Independent clause first)
- The student who studied hard passed the exam. (Dependent clause embedded)
Use of Complex Sentences in Context
Complex sentences are used to:
- Show relationships: They clearly indicate cause and effect, time, condition, or contrast between ideas.
Example: Since the road was blocked, we had to find an alternative route. (Cause)
- Add detail and depth: They allow writers to provide additional information without creating choppy sentences.
Example: The old woman, who lived next door, always offered us sweets. (Additional detail)
- Improve flow and coherence: They help to connect ideas smoothly, making writing more sophisticated and easier to read.
Example: If you finish your homework early, you can watch television. (Condition)
- Vary sentence structure: Using a mix of simple, compound, and complex sentences makes writing more engaging.

Instructional Procedures
Step 1: Introduction
Time: 5 minutes
Teaching Skill: Recalling/Engaging
Teacher’s Activity: The teacher greets the students and reviews previous knowledge on simple and compound sentences by asking students to give examples of each. The teacher then introduces the topic of complex sentences as a way to express more detailed ideas.
Pupils’ Activity: Pupils respond to questions about simple and compound sentences and listen attentively to the introduction of the new topic.
Learning Point: Prior sentence knowledge activated
Step 2: Explanation of Complex Sentences
Time: 10 minutes
Teaching Skill: Explaining/Defining
Teacher’s Activity: The teacher defines a complex sentence, explaining that it combines an independent clause with at least one dependent clause. The teacher provides a simple example and highlights the two clauses.
Pupils’ Activity: Pupils listen to the explanation, ask clarifying questions, and copy the definition into their notebooks.
Learning Point: Definition of complex sentence
Step 3: Identifying Independent and Dependent Clauses
Time: 10 minutes
Teaching Skill: Demonstrating/Analysing
Teacher’s Activity: The teacher explains the characteristics of independent and dependent clauses using several examples. The teacher writes sentences on the board and guides students to identify which part is independent and which is dependent, explaining why.
Pupils’ Activity: Pupils actively participate in identifying clauses in example sentences and explain their reasoning.
Learning Point: Clause identification skills
Step 4: Subordinating Conjunctions and Relative Pronouns
Time: 8 minutes
Teaching Skill: Listing/Categorising
Teacher’s Activity: The teacher introduces common subordinating conjunctions and relative pronouns, explaining their role in connecting clauses and introducing dependent clauses. The teacher displays a chart or writes them on the board.

Learning Point: Connectors of clauses
Step 5: Guided Practice – Constructing Complex Sentences
Time: 10 minutes
Teaching Skill: Guiding/Facilitating
Teacher’s Activity: The teacher guides students to construct complex sentences. The teacher might provide an independent clause and ask students to add a dependent clause using a specific subordinating conjunction, or vice versa. The teacher can also guide students through an online quiz on complex sentences, discussing answers as a class.
Pupils’ Activity: Pupils construct complex sentences orally and in writing, participating in the online quiz and discussing their choices.
Learning Point: Sentence construction practice
Step 6: Application – Using Complex Sentences in Context
Time: 7 minutes
Teaching Skill: Applying/Contextualising
Teacher’s Activity: The teacher provides short passages or prompts and asks students to revise simple sentences into complex ones or to write sentences that show specific relationships (e.g., cause, condition) using complex structures. The teacher emphasizes the importance of context.
Pupils’ Activity: Pupils apply their knowledge by revising sentences or writing new ones, focusing on appropriate use of complex structures.
Learning Point: Contextual sentence usage
Step 7: Evaluation/Review
Time: 5 minutes
Teaching Skill: Questioning/Assessment
Teacher’s Activity: The teacher evaluates the learning by asking the following questions:
- What is a complex sentence?
- Give an example of an independent clause.
- Name two common subordinating conjunctions.
- Construct a complex sentence using the word “although”.
Pupils’ Activity: Pupils answer orally and in writing.
Learning Point: Complex sentence understanding assessed

Pupils’ Activity: Pupils listen to the summary and ask any final questions.
Learning Point: Lesson concepts consolidated
Continuous Assessment/Further Study
Type: Homework/Practice Exercise
Instruction: Complete the following tasks in your English Language notebook:
- Identify the independent and dependent clauses in each of these sentences:
- Although it was late, she continued to read her book.
- He will succeed if he works hard.
- The dog barked loudly whenever the postman arrived.
- Construct three complex sentences of your own, using a different subordinating conjunction for each.
- Find a short paragraph from a newspaper or magazine and underline all the complex sentences you can identify.
Lesson Keywords
- Complex sentence – A sentence with one independent clause and at least one dependent clause.
- Independent clause – A clause that can stand alone as a complete sentence.
- Dependent clause – A clause that cannot stand alone and relies on an independent clause for meaning.
- Subordinating conjunction – A word that introduces a dependent clause and connects it to an independent clause (e.g., because, although, when).
- Relative pronoun – A pronoun that introduces a dependent clause (e.g., who, which, that).
Differentiation
For students who struggle, provide simpler sentences for identification and construction, and focus on one type of subordinating conjunction at a time. For advanced learners, challenge them to write paragraphs using a variety of complex sentence structures or to analyze the effect of complex sentences in literary texts.
