Because vs. so: reason vs. result

"Because" gives the reason for something: "I stayed home because it was raining" ("because it was raining" is the reason). "So" gives the result: "It was raining, so I stayed home" ("I stayed home" is the result). They connect the same two ideas, but in opposite directions.

Common mistakes learners make

Mixing up the order of reason and result between because and so, using the wrong conjunction for how the sentence is arranged. It's also common to forget the comma before but, or, and so when they connect two complete sentences.
