Connectors: because, so, but, although
Cause, result and contrast in one kit: because (reason), so (result), but/although (contrast); no comma before because
I can join clauses with because/so/but/although without doubling connectors.
Look at these examples. Can you spot the grammar pattern?

Pay attention to the highlighted parts. What do they have in common?
Four workhorses:
| Connector | Job | Example |
|---|---|---|
| because | reason | We stayed in because it rained. |
| so | result | It rained, so we stayed in. |
| but | contrast | It rained, but we went out. |
| although | stronger contrast | Although it rained, we went out. |
because/so are mirror twins: swap the clause order, swap the word. Although-clauses can start the sentence with a comma after them. Never double up: *Although it rained, but we went out.
- although + but doubled: pick one
- Comma forced before because: usually none
- so/because swapped: because = reason, so = result
Common Error Patterns
