English Grammar Mastery: From Foundations to Fluency

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.
