Conjunctions in English: Build Better Sentences

What Are Conjunctions?

A conjunction is a word that connects two words, phrases, or sentences together. Without conjunctions, our sentences would be very short and choppy. They help us express more complex ideas in a natural and fluent way.

For example, instead of saying ‘I like coffee. I like tea.’ we can say ‘I like coffee and tea.’ Much smoother, right?

Simple Examples to Get Started

I want to go out, but it is raining.
She studies hard because she wants to pass her exam.
You can have cake or ice cream.
He was tired, so he went to bed early.

Notice how each conjunction plays a different role. Some add information, some show contrast, and some explain a reason. Let us look at this more closely.

The Main Types of English Conjunctions

There are three main groups of conjunctions in English. Understanding these groups will help you use them correctly and confidently.

1. Coordinating Conjunctions

These conjunctions connect two equal parts of a sentence, such as two nouns, two verbs, or two independent clauses. A simple way to remember them is the acronym FANBOYS.

Conjunction	Meaning	Example
For	Explains a reason	She left early, for she was tired.
And	Adds information	I have a dog and a cat.
Nor	Adds a negative idea	He does not drink, nor does he smoke.
But	Shows contrast	It is cold but sunny today.
Or	Gives a choice	Do you want tea or coffee?
Yet	Shows surprise or contrast	She is young, yet very wise.
So	Shows a result	I was hungry, so I ate.

2. Subordinating Conjunctions

These conjunctions connect a main clause to a dependent clause. The dependent clause cannot stand alone. It needs the main clause to make sense.

because – She is happy because she got a promotion.
although – Although it was raining, we went for a walk.
when – Call me when you arrive.
if – If you study, you will pass.
while – He cooked dinner while she set the table.
since – Since you are here, let us start.

Important tip: when the subordinating conjunction comes at the beginning of the sentence, use a comma after the first clause. When it comes in the middle, no comma is needed.

3. Correlative Conjunctions

These conjunctions work in pairs. They always appear together and connect two balanced ideas.

Pair	Example
both … and	She speaks both French and Spanish.
either … or	You can either call or send an email.
neither … nor	He is neither tall nor short.
not only … but also	She is not only smart but also kind.
whether … or	I do not know whether to stay or leave.

Why Conjunctions Matter in English

Using conjunctions correctly makes your English sound more natural and more advanced. They allow you to link your ideas smoothly and avoid repeating yourself. Good writers and speakers use a variety of conjunctions to show different relationships between ideas.

Here is a practical reason: in everyday conversation, in emails, and in writing tasks, conjunctions help you express contrast, cause, choice, and consequence. Mastering them will significantly improve your communication skills in English.

Comparison with Other Languages

If your native language is French or Spanish, you will find that many conjunctions have a direct equivalent. However, the grammar rules around them can be different.

English	French	Spanish	Notes
and	et	y / e	Very similar usage
but	mais	pero / sino	Spanish has two words for ‘but’
because	parce que	porque	English uses one word, not two
although	bien que + subjunctive	aunque + subjunctive	English does not require a subjunctive here
if	si	si	Very similar, but verb tenses differ

One key difference is that English does not use the subjunctive mood after most conjunctions. This makes English conjunctions slightly easier to use than in French or Spanish.

A Complete Example

Let us bring everything together in a short paragraph that uses different types of conjunctions:

‘Maria wants to learn English because she has a new job. She studies every day, but she also enjoys it. Although it is sometimes difficult, she never gives up. She listens to podcasts and watches films in English. If she keeps practising, she will become fluent very soon.’

Can you identify all the conjunctions? Try to name their type: coordinating, subordinating, or correlative.

Key Takeaways

Conjunctions connect words, phrases, or clauses together.
There are three main types: coordinating (FANBOYS), subordinating, and correlative.
Use a comma before coordinating conjunctions that join two independent clauses.
Use a comma after a subordinating clause when it starts the sentence.
Conjunctions help you sound more fluent and natural in English.
Compared to French and Spanish, English conjunctions are generally simpler to use.
