1️⃣ Lesson Overview
In this lesson, you will learn about conjunctions, which are words used to connect words, phrases, or clauses within sentences. Conjunctions help organise ideas and show logical relationships between different parts of a sentence.
By linking elements together, conjunctions make communication clearer and more coherent.
By the end of this lesson, you will be able to:
✅ define what a conjunction is
✅ recognise the main types of conjunctions
✅ understand how conjunctions express logical relationships
✅ identify conjunctions in sentences
2️⃣ Concept Introduction
Consider the following sentence:
The team completed the analysis and published the results.
The word and connects two actions.
| Word | Function |
|---|---|
| and | connects two verbs |
Another example:
The experiment was successful because the procedure was carefully followed.
| Word | Function |
|---|---|
| because | connects two clauses and shows cause |
Words that perform these connecting roles are called conjunctions.
3️⃣ Core Explanation
A conjunction is a word that connects words, phrases, or clauses.
Conjunctions are important because they show how ideas are related within a sentence.
They may connect:
-
two words
-
two phrases
-
two clauses
Example:
The researcher analysed the data and wrote the report.
| Word | Role |
|---|---|
| and | connects two verbs |
Another example:
The results were reliable because the method was accurate.
| Word | Role |
|---|---|
| because | connects two clauses |
Conjunctions therefore help express logical relationships between ideas.
4️⃣ Rule Table – Types of Conjunctions
There are three main types of conjunctions in English.
| Type of Conjunction | Function | Example |
|---|---|---|
| Coordinating Conjunction | connects words, phrases, or independent clauses | and, but, or |
| Subordinating Conjunction | introduces dependent clauses | because, although, if |
| Correlative Conjunction | works in pairs to connect elements | either…or, neither…nor |
Example sentence:
The researcher collected the data and analysed it carefully.
| Word | Type |
|---|---|
| and | coordinating conjunction |
Another example:
Although the experiment was difficult, the results were valuable.
| Word | Type |
|---|---|
| although | subordinating conjunction |
5️⃣ Logical Connections
Conjunctions often express specific logical relationships between ideas.
| Relationship | Conjunction | Example |
|---|---|---|
| Addition | and | The team analysed the data and prepared the report. |
| Contrast | but | The method was simple, but the results were significant. |
| Cause | because | The experiment succeeded because the conditions were controlled. |
| Condition | if | If the temperature changes, the results may vary. |
| Result | so | The data was incomplete, so the study continued. |
Understanding these relationships helps learners express ideas clearly.
6️⃣ Common Errors
⚠ Common Error 1: Using a Comma Instead of a Conjunction
Incorrect:
The researcher collected the data, analysed the results.
Correct:
The researcher collected the data and analysed the results.
Explanation:
Independent clauses require a conjunction or proper punctuation.
⚠ Common Error 2: Using the Wrong Conjunction
Incorrect:
The experiment failed and the equipment malfunctioned.
Correct:
The experiment failed because the equipment malfunctioned.
Explanation:
The relationship is cause, not addition.
⚠ Common Error 3: Double Conjunction
Incorrect:
Although the results were accurate but the sample size was small.
Correct:
Although the results were accurate, the sample size was small.
Explanation:
Do not combine although with but in the same clause.
⚠ Common Error 4: Incorrect Correlative Structure
Incorrect:
Either the researcher or the technicians is responsible.
Correct:
Either the researcher or the technicians are responsible.
Explanation:
The verb agrees with the closest subject.
⚠ Common Error 5: Fragment After Subordinating Conjunction
Incorrect:
Because the data was incomplete.
Correct:
The study continued because the data was incomplete.
Explanation:
A subordinating conjunction must introduce a complete clause structure.
7️⃣ Lesson Mastery
After completing this lesson, you should now be able to:
✅ define what a conjunction is
✅ recognise different types of conjunctions
✅ understand logical relationships expressed by conjunctions
✅ identify conjunctions in sentences
