Conjunctions: And, But, Or, So, Because

What Are Conjunctions?

Think of conjunctions as the glue that connects words, phrases, or sentences. Without them, our writing would sound choppy. With them, we can add details, show differences, explain reasons, and connect thoughts clearly.

Five Common Conjunctions

And Adds information or combines ideas I like apples and bananas.
But Shows contrast or difference I like coffee, but I don’t like tea.
Or Offers a choice Would you like tea or coffee?
So Shows a result It rained, so we stayed inside.
Because Gives a reason She is tired because she worked late.

How to Use These Conjunctions
