We use the coordinating conjunction “so” to combine two complete sentences that have a cause and effect relationship.

You can also think of the second sentence as resulting from the first.


”So” — Expressing a Result or Effect

When using “so,” you can think of the second sentence as a logical conclusion that makes sense based on the idea in the first sentence. It expresses an effect.

”So” can also introduce a decision based on the first sentence.

Examples of “so” introducing an effect or decision

Introducing a result or effect

It started raining, so everyone left the park.
