Coordinating Conjunctions

Coordinating conjunctions are words that join two equal parts of a sentence. They can connect: two words, two phrases, and two independent clauses (complete sentences). They make our speaking and writing smoother. Think of them as glue for your sentences. The seven coordinating conjunctions are: and, but, or, so, for, nor, and yet. A simple way to remember them is FANBOYS.

How to use

Rule 1: And

Use 'and' when you want to join similar ideas or add more information.

  • I have a cat and a dog.
  • She opened the window and sat down.
Rule 2: But

Use 'but' when the second idea is different from the first one to show contrast.

  • He is young, but he is very responsible.
  • The food was cheap, but it was delicious.
Rule 3: Or

Use 'or' when there are two or more possibilities to give a choice.

  • Would you like tea or coffee?
  • We can leave now or wait for John.
Rule 4: So

Use 'so' when the second part is the result of the first part.

  • It was late, so we went home.
  • I was hungry, so I made a sandwich.
Rule 5: Yet

'Yet' is similar to 'but', but it often shows that something is surprising or unexpected to show an unpredictable contrast.

  • The task was difficult, yet everyone finished it.
  • She was fired, yet she kept working.
Rule 6: For

'For' means 'because', use it to explain or provide a reason or purpose for something.

  • We stayed inside, for it was snowing.
  • She was happy, for she had passed the exam.
Rule 7: Nor

Use 'nor' to add another negative statement. It often follows words like not, never, or neither.

  • He doesn't like coffee, nor does he like tea.
  • They were not ready, nor were they prepared.
Rule 8: A comma before a coordinating conjunction

When a coordinating conjunction joins two independent clauses (complete sentences), use a comma before the conjunction.

  • I finished my homework, and I watched TV.
  • It was raining, so we stayed indoors.
When you connect only words or short phrases, do not use a comma.
  • I bought apples and oranges.
  • He is kind but shy.
