Conjunctions
Conjunctions — and, but, or, because, so — connect your ideas into smooth sentences. Learn how each one works, when to use them, and real examples from everyday English.
Simple explanation
A conjunction is a joining word. It connects two words, two phrases, or two sentences into one smooth idea.
Without conjunctions, every thought lives in its own separate sentence. With them, your English flows.
Why it matters
Short sentences are fine. But when every sentence is short and separate, your English sounds choppy — like a beginner reading from a list. Conjunctions are what let you sound like a confident, natural speaker who can hold a thought together.
The five you will use every day
| Conjunction | What it does | Example |
|---|---|---|
| and | Adds two ideas together | I like tea and coffee. |
| but | Shows contrast or surprise | I was tired but I kept going. |
| or | Shows a choice | Tea or coffee? |
| because | Gives a reason | I was late because of traffic. |
| so | Shows a result | It was raining, so I stayed home. |
Wrong vs right
Both say the same thing. The second sounds like a confident speaker. The first sounds like a list.
Daily life usage
- And: She is smart and hardworking.
- But: The food was good but a little too spicy.
- Or: You can call me or send a message.
- Because: I chose this job because it gives me time to learn.
- So: The meeting ended early, so we had chai together.
Three more useful conjunctions
Although / Even though — shows contrast stronger than but:
"Although I was nervous, I gave a clear answer."
When — connects two events in time:
"When I reach the office, I will check your email."
If — shows a condition:
"I will come if the meeting finishes on time."
These three — although, when, and if — are called subordinating conjunctions. They connect a main idea to a supporting idea. The supporting idea cannot stand alone: "Although I was nervous" is incomplete on its own. It needs a main clause: "Although I was nervous, I gave a clear answer." Once you get comfortable with these, your sentences will feel much more natural and complete.
One small rule: comma before but and so
When but or so joins two complete sentences (each has its own subject and verb), add a comma before it.

Quick summary
- Conjunctions join ideas — they make your sentences flow.
- And adds, but contrasts, or gives choices, because gives reasons, so gives results.
- Use a comma before but and so when joining two complete sentences.
Take two short sentences from your day and join them with but, because, or so. "I was nervous, but I spoke anyway." "I stayed late because the work was important." That one habit — joining thoughts — makes your English sound immediately more fluent.
