Coordinating, Subordinating, and Correlative Conjunctions: The Full Map

Introduction: The Glue That Holds Sentences Together

Conjunctions connect words, phrases, and clauses. English has three types, and each follows different rules.

I was tired, but I worked. (coordinating — equal clauses)
Although he was tired, he worked. (subordinating — dependent clause)
Neither he nor she came. (correlative — paired)

Mixing them up creates errors. This article maps all three clearly.

Core Meaning and Rule

Rule box: Coordinate equal units with FANBOYS. Subordinate dependent clauses with subordinators. Correlative pairs must be parallel.

Type	Function	Examples
Coordinating	Connect equal words/clauses	for, and, nor, but, or, yet, so (FANBOYS)
Subordinating	Introduce dependent clauses	because, although, if, when, while, unless, so that
Correlative	Work in pairs	either…or, neither…nor, not only…but also, both…and

Forms, Patterns, and Sentence Position

1. Coordinating Conjunctions (FANBOYS)

I was tired, but I continued.
She studied hard, so she passed.
You can have tea or coffee.

Coordinating conjunctions connect two independent clauses. Use a comma before the conjunction.

2. Subordinating Conjunctions

Although he was tired, he worked.
I stayed home because it was raining.
If you study, you will pass.

Subordinating conjunctions introduce a dependent (subordinate) clause. The clause cannot stand alone.

Common subordinators:

• Cause: because, since, as
• Contrast: although, though, even though, while
• Condition: if, unless, provided that
• Time: when, while, before, after, until, as soon as
• Purpose: so that, in order that
• Result: so…that, such…that

3. Correlative Conjunctions

Either you or she must go.
Neither he nor I was present.
Not only does she sing, but she also dances.
Both Rahul and Priya came.

Correlative conjunctions work in pairs. The structures after each part must be parallel.

Wrong: Not only she sings but also dances.
Right: Not only does she sing, but she also dances.

4. Common Errors with Conjunctions

Double conjunction:

Wrong: Although he was tired but he worked.
Right: Although he was tired, he worked. / He was tired, but he worked.

Neither…or:

Wrong: Neither he or she came.
Right: Neither he nor she came.

Because of + clause:

Wrong: Because of he was ill.
Right: Because he was ill. / Because of his illness.

Decision Checklist

1. Are you connecting two equal clauses? → Coordinating (FANBOYS).
2. Are you adding a dependent clause? → Subordinating.
3. Are you using a pair? → Correlative.
4. Check for double conjunctions. Don’t use although…but or because…so.
5. Check parallelism with correlatives.

Exam Traps and Usage Notes

Trap 1: Although…But

Wrong: Although he was tired but he worked.
Right: Although he was tired, he worked.

Use one or the other, not both.

Trap 2: Neither…Or

Wrong: Neither he or she came.
Right: Neither he nor she came.

The pair is neither…nor.

Trap 3: Because Of + Clause

Wrong: Because of he was ill.
Right: Because he was ill.

Because of takes a noun, not a clause.

Trap 4: So That + Tense

Wrong: I studied hard so that I can pass. (past context)
Right: I studied hard so that I could pass.

Match the tense of so that clause to the main clause.

Trap 5: Parallelism with Correlatives

Wrong: Not only she sings but also dances.
Right: Not only does she sing, but she also dances.

Keep the structures parallel after each part of the pair.

Common Mistakes

Wrong	Right	Why
Although…but	Although… / …, but…	No double conjunction.
Neither…or	Neither…nor	Correct pair.
Because of he was ill.	Because he was ill.	Because of + noun.

Summary

Rule: Coordinating = equal units (FANBOYS). Subordinating = dependent clauses. Correlative = parallel pairs. Never double up although…but or because…so.

Memory trick: FANBOYS for equals. Subordinators for dependents. Correlatives come in pairs.

Revise these:

• I was tired, but I worked. (coordinating)
• Although I was tired, I worked. (subordinating)
• Neither he nor she came. (correlative)
• Not only does she sing, but she also dances. (correlative)
