There are seven coordinating conjunctions in the English language, which are used to link the independent clauses: You can use the acronym FANBOYS to help you remember them. Remember you need a comma to join two independent clauses joined by one of these.
Use the conjunction and to add information or combine related ideas.
Jack and Jil went up the hill.
I like to go swimming and rock climbing.
Use the conjunction or to show a choice.
I want a bunny or a cat.
You can go swimming or rock climbing.
Use the conjunction but to show a difference.
I like pizza, but my sister doesn't.
Paul already knows how to swim, but Louis is still learning.
The conjunction so shows that the first idea caused the second idea.
