Conjunctions are small words that join ideas, words, or sentences. At A2 level, you need to use and, but, or, so, and because correctly. This lesson explains when to use each one—with clear examples.
And adds similar or positive ideas.
✅ I like tea and coffee.
✅ She is smart and kind.
But shows contrast or unexpected information.
✅ It’s sunny, but I feel cold.
✅ He’s tired, but he can’t sleep.
Or gives a choice or alternative.
✅ Do you want tea or coffee?
✅ We can walk or take the bus.
So shows a result or consequence.
✅ It’s raining, so I’ll take an umbrella.
✅ She studied hard, so she passed the test.
Use because to give a reason.
✅ I’m late because the bus was slow.
✅ She’s happy because she got a good grade.
⚠️ Never start a sentence with “Because...” and stop after the comma. Always include both parts.
❌ Because I was tired. → ✅ I went to bed early because I was tired.
When a conjunction joins two complete sentences, use a comma before the conjunction.
✅ I wanted to go, but it was too late.
✅ She didn’t study, so she failed.
✅ He was hungry, so he ate lunch.
No comma is needed if only one part is a complete sentence.
✅ I like apples and oranges. (not two full sentences)
correct “I stayed home because I was sick.”
incorrect “I stayed home, so I was sick.” — “so” shows result, not reason
