A Conjunctions and Sample Paragraph

A conjunction is a word or phrase that connects words, phrases, or ideas.

Conjunctions help us show the relationship between different parts of a sentence. They can show addition, choice, contrast, a negative idea, a result, or a purpose.

coffee and tea
Monday or Tuesday
I wanted to go, but I was busy.
I don't smoke, nor do I drink alcohol.
I was tired, so I went home.
I left early so that I could catch the bus.
Sample Paragraph

I recently started a new job, and I really enjoy working there. I can take the bus or drive to work, but I usually take the bus because parking is expensive. I do not have to work at night, nor do I have to work on weekends. My office is quite busy, so I organize my tasks every morning. I also arrive a little early so that I can prepare for the day.

Tip: Look at the ideas on both sides of the conjunction. The conjunction tells us how those ideas are connected.

B And / Or
And

Use and to connect similar information or to add another idea.

and = addition
  • Sarah speaks English and French.
  • I bought some bread and milk.
  • I finished my work, and I went home.
Or

Use or when there is a choice or alternative.

or = choice / alternative
  • Would you like tea or coffee?
  • We can meet Monday or Tuesday.
  • You can call me, or you can send me an email.

Remember:

and → adds another idea
or → gives another choice

We need pens and paper.
We can travel by bus or train.

C But / Nor
But

Use but to connect two ideas that contrast or are different from what we might expect.

but = contrast
  • The apartment is small, but it is comfortable.
  • I wanted to attend the meeting, but I was sick.
  • The job is difficult, but the salary is good.

The second idea often gives a different side of the situation.

The course is expensive, but it is very useful.
Nor

Use nor to add another negative idea.

nor = and not / also not
  • I don't smoke, nor do I drink alcohol.
  • She doesn't drive, nor does she own a car.
  • We didn't complain, nor did we ask for a refund.

After nor, the helping verb normally comes before the subject.

nor + helping verb + subject + verb

nor do I work
nor does she drive
nor did they complain

CLB 5–6 Tip: Nor is less common in everyday conversation. You will often hear a simpler structure:

I don't smoke, and I don't drink alcohol.

D So / So That

So and so that look similar, but they have different meanings.

So

Use so to introduce a result.

reason → so → result

I was tired, so I went to bed early.

Being tired caused the person to go to bed early.

  • The bus was late, so I arrived late for work.
  • It was raining, so we stayed inside.
  • I needed some groceries, so I went to the supermarket.
So That

Use so that to introduce a purpose or goal.

action → so that → purpose

I left home early so that I could catch the bus.

Why did I leave home early?

My purpose was to catch the bus.

  • I wrote down the address so that I wouldn't forget it.
  • She speaks slowly so that everyone can understand her.
  • We are saving money so that we can buy a house.
Compare So and So That
I was hungry, so I made dinner.
Result: I made dinner because I was hungry.

I went to the store so that I could buy food.
Purpose: My reason for going was to buy food.

Remember:

so → result
so that → purpose

E Key Points to Remember

Conjunctions connect words or ideas. The conjunction you choose depends on the relationship between those ideas.

Ask Yourself

Am I showing a contrast?
→ but

Am I adding another negative idea?
