Prerequisite/Previous Knowledge
Students should have a good understanding of simple sentences, subjects, verbs, and basic sentence structure.
Lesson Content/Board Summary
Complex Sentence
Definition of a Complex Sentence
A complex sentence is a sentence that contains one independent clause and at least one dependent (or subordinate) clause. The independent clause can stand alone as a complete thought, while the dependent clause cannot stand alone and relies on the independent clause for its full meaning.
Example:
- Although it was raining, we decided to go for a walk. (Dependent clause underlined)
- We decided to go for a walk although it was raining. (Dependent clause underlined)
Essential Features of Complex Sentences
Subordinators (Subordinating Conjunctions)
Subordinators are words or phrases that introduce dependent clauses and connect them to independent clauses. They establish the relationship between the two clauses, such as time, cause, condition, contrast, or purpose.
Common subordinators include:
- Time: after, as, as soon as, before, by the time, once, since, until, when, whenever, while
- Cause/Reason: as, because, now that, since
- Condition: if, even if, in case, provided that, unless
- Contrast/Concession: although, even though, though, whereas, while
- Purpose: in order that, so that
- Place: where, wherever
- Manner: as, as if, as though
Examples:
- Because he was tired, he went to bed early. (Subordinator: Because)
- She will succeed if she works hard. (Subordinator: if)
- I waited until the bus arrived. (Subordinator: until)
Types of Clauses
Complex sentences are made up of two main types of clauses:
- Independent Clause (Main Clause): This is a complete sentence that can stand alone and express a complete thought. It contains a subject and a verb.
- Dependent Clause (Subordinate Clause): This clause cannot stand alone as a complete sentence. It depends on the independent clause for its meaning and is introduced by a subordinator. It also contains a subject and a verb.
Examples:
- The dog barked (Independent Clause) when the mailman arrived (Dependent Clause).
- Although it was cold (Dependent Clause), she wore a light jacket (Independent Clause).
- He studies hard (Independent Clause) so that he can pass his exams (Dependent Clause).
Concord (Subject-Verb Agreement)
Concord, or subject-verb agreement, must be maintained in both the independent and dependent clauses of a complex sentence.
- The verb in the independent clause must agree with its subject.
- The verb in the dependent clause must also agree with its subject.
Examples:
- She sings beautifully when she is happy. (She sings – singular subject, singular verb; she is – singular subject, singular verb)
- If they arrive late, we will start without them. (They arrive – plural subject, plural verb; we will start – plural subject, plural verb)
- The student who studies regularly passes the exam. (who studies – singular relative pronoun refers to ‘student’, singular verb; The student passes – singular subject, singular verb)

Instructional Procedures
Step 1: Introduction
Time: 5 minutes
Teaching Skill: Elicitation/Recalling
Teacher’s Activity: The teacher greets the students and asks them to recall what they know about simple sentences and clauses. The teacher then introduces the topic of complex sentences.
Pupils’ Activity: Pupils respond to the teacher’s questions and listen attentively to the introduction.
Learning Point: Prior knowledge of sentences
Step 2: Defining Complex Sentences
Time: 10 minutes
Teaching Skill: Explanation/Definition
Teacher’s Activity: The teacher defines a complex sentence, explaining that it combines an independent clause with at least one dependent clause. The teacher writes the definition and a basic example on the board.
Pupils’ Activity: Pupils listen, ask questions for clarity, and copy the definition into their notebooks.
Learning Point: Definition of complex sentence
Step 3: Identifying Subordinators
Time: 10 minutes
Teaching Skill: Illustration/Identification

Continuous Assessment/Further Study
Type: Homework
Instruction: Complete the following tasks in your English Language notebook:
- Define a complex sentence in your own words.
- List five different subordinators and use each in a unique complex sentence.
- Identify the independent and dependent clauses in the following sentences:
- Because she was late, she missed the beginning of the movie.

- Although it was raining, they played football.
- Write three complex sentences of your own, ensuring correct subject-verb agreement in both clauses.
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.
- Subordinator – A word or phrase that introduces a dependent clause and connects it to an independent clause.
- Concord – Subject-verb agreement.
Differentiation
For students who grasp the concept quickly, encourage them to write complex sentences using a variety of subordinators and to identify different types of dependent clauses (e.g., adverbial, adjectival). For students needing more support, provide simpler examples and focus on identifying the main clause and a single dependent clause, using a limited set of common subordinators.
