What coordinating conjunction is used to join sentences that contrast with each other?

The coordinating conjunction used to join sentences that contrast with each other is but.

Here's an example:

* The weather was beautiful, but I stayed inside all day.

Other coordinating conjunctions exist, but they don't specifically indicate contrast:

* and (joins similar ideas)

* or (presents alternatives)

* so (shows consequence)

* for (provides a reason)

* yet (also indicates contrast, but is often used in more formal writing)
