Because and so join two ideas when one causes the other. They work like but, but they show why something happened.
| Reason first, with so | Result first, with because |
|---|---|
| I was cold, so I put on a coat. | I put on a coat because I was cold. |
| It started to rain, so we went inside. | We went inside because it started to rain. |
Key idea
Because comes right before the reason. So comes right before the result: what happened.
Why it works
Readers want to know why. Because and so turn two separate facts into a story of cause and effect, and they make an opinion convincing later on.
Worked example: Find the reason
“We stayed off the pond ___ the ice was thin.”
- Why did we stay off the pond? The ice was thin. That is the reason.
- The reason comes right after the blank.
- Because goes before the reason.
Answer: “We stayed off the pond because the ice was thin.”
Common mistake
Swapping the reason and the result: “I was hungry because I ate lunch.” Ask: which happened first, and which caused the other? The cause goes right after because.
For the grown-up. Ask “why?” about everyday things and let your child answer with because: “Why are you wearing boots?” “Because it is muddy.” Then flip it with so: “It is muddy, so I am wearing boots.”
