1. Lesson Overview
In this lesson, you will learn:
- What coordination is
- What subordination is
- Coordinating conjunctions (FANBOYS)
- Subordinating conjunctions
- Logical relationships (cause, contrast, condition, time, result)
- Comma rules
- Common structural errors
This lesson explains how ideas connect logically.
2. Coordination
Coordination joins equal ideas.
Structure:
Independent clause + coordinating conjunction + independent clause
FANBOYS
for
and
nor
but
or
yet
so
Example
The Nile River is the longest river in Africa, and it supports millions of people.
Two equal ideas.
Logical Meanings
|
Conjunction |
Meaning |
|
for |
reason |
|
and |
addition |
|
nor |
negative addition |
|
but |
contrast |
|
or |
choice |
|
yet |
contrast (unexpected) |
|
so |
result |
Example Meanings
Addition:
She studied hard, and she passed the exam.
Contrast:
The climate is harsh, but people adapt.
Result:
It rained heavily, so the match was cancelled.
3. Comma Rule for Coordination
When joining two independent clauses:
Comma + conjunction required.
Incorrect:
She studied hard and she passed.
Correct:
She studied hard, and she passed.
No comma if subject is same and verb phrase is shared.
She studied hard and passed the exam.
4. Subordination
Subordination joins unequal ideas.
One clause is dependent.
Common Subordinators
because
although
if
when
while
since
after
before
unless
until
whereas
Example
Although the Amazon rainforest is vast, it faces deforestation.
Dependent clause:
Although the Amazon rainforest is vast
Independent clause:
it faces deforestation
5. Logical Relationships in Subordination
Cause
because/since
She left because she was tired.
Contrast
although/whereas
Although it was cold, they continued climbing.
Condition
if/unless
If the temperature rises, ice melts.
Time
when / while/after / before
When the lecture ended, students left.
6. Comma Rule for Subordination
If a dependent clause comes first → comma is required.
Because she was tired, she went home.
If an independent clause comes first → comma is not required.
She went home because she was tired.
7. Coordination vs Subordination (Comparison)
|
Coordination |
Subordination |
|
Equal importance |
Unequal importance |
|
Two independent clauses |
One independent + one dependent |
|
Uses FANBOYS |
Uses subordinators |
Example comparison:
Compound:
She studied hard, and she passed.
Complex:
Because she studied hard, she passed.
The second sentence emphasizes the cause.
8. Common Errors
⚠ Comma splice
Incorrect:
She studied hard, she passed.
Correct:
She studied hard, so she passed.
⚠ Fragment
Incorrect:
Although she studied hard.
Correct:
Although she studied hard, she passed.
⚠ Wrong conjunction meaning
Incorrect:
She was tired, so she continued working. (logical confusion)
9. End of Lesson Check
You should now be able to:
✅Use FANBOYS correctly
✅Use subordinators accurately
✅Apply comma rules properly
✅Express logical relationships clearly
✅Avoid comma splices and fragments
