Good writing joins ideas together smoothly. The three most useful joining words at A1 level are and, but, and because. They turn short, choppy sentences into clear, connected writing. This lesson shows you exactly when and how to use each one.

1. AND – to add

Use and to add similar information.

  • I like tea. I like coffee. → I like tea and coffee.
  • Emma studies English and she works at night.

2. BUT – to show a difference

Use but to add surprising or opposite information.

  • The class is difficult but interesting.
  • James is tired but he is happy.

3. BECAUSE – to give a reason

Use because to answer “why?” It gives the reason.

  • I study hard because I want good grades.
  • Thomas is happy because it is the weekend.

4. Commas with joining words

Word Comma rule Example
and / but Use a comma before it when it joins two full sentences. She is rich, but she is not happy.
and / but No comma when it joins two words. tea and coffee
because If it starts the sentence, put a comma after the reason. Because it was late, I went home.
Two ways with “because”Both are correct: “I stayed home because I was sick.” and “Because I was sick, I stayed home.” When “because” comes first, add a comma in the middle.
Tutor tipA very common habit carried over from other languages is joining everything with “and” – long sentences with “and… and… and.” In English, that sounds childish. Mix your joining words: use but for contrast and because for reasons. Also, do not use a double joiner like “because… so” together – choose one: “Because I was tired, I slept” OR “I was tired, so I slept.”

Examples from EduCareer

  • Emma likes reading and writing.
  • James wants to rest, but he has homework.
  • Thomas studies every day because he wants to pass his exam.
Common mistakes

I was sick, because I stayed home.  →  I stayed home because I was sick. (reason follows because)

Because I was tired so I slept.  →  Because I was tired, I slept.

The class is hard and interesting but long and I like it and…  →  The class is hard but interesting.
