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.
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.
Use and to connect similar information or to add another idea.
Use or when there is a choice or alternative.
Remember:
and → adds another idea
or → gives another choice
We need pens and paper.
We can travel by bus or train.
Use but to connect two ideas that contrast or are different from what we might expect.
The second idea often gives a different side of the situation.
Use nor to add another negative idea.
After nor, the helping verb normally comes before the subject.
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.
So and so that look similar, but they have different meanings.
Use so to introduce a result.
Being tired caused the person to go to bed early.
Use so that to introduce a purpose or goal.
Why did I leave home early?
My purpose was to catch the bus.
Remember:
so → result
so that → purpose
Conjunctions connect words or ideas. The conjunction you choose depends on the relationship between those ideas.
| Conjunction | Main Use | Example |
| and | addition | I work and study. |
| or | choice | Call or email me. |
| but | contrast | It's small, but comfortable. |
| nor | another negative idea | I don't smoke, nor do I drink. |
| so | result | I was tired, so I rested. |
| so that | purpose | I studied so that I could pass. |
Final Tip: Don't choose a conjunction only because it sounds familiar. Read the ideas before and after the blank and decide how they are connected.
addition → and
choice → or
contrast → but
negative addition → nor
result → so
purpose → so that
