Because with から
から after a clause means "because." You can put the reason first or the result first. Our lesson on conjunctions covers から alongside other connecting patterns, and there's more on から as a particle in our particles guide.
Two Patterns
Reason first, then result
The reason clause ends with から, followed by the result:
明日雨だから、出かけない。
Because it'll rain tomorrow, I'm not going out.
Result first, then reason
State the result, then explain why:
出かけない。明日雨だから。
I'm not going out. Because it'll rain tomorrow.
Plain or Polite
から can follow either plain form or polite form. No special conjugation needed:
- 忙しいから (plain)
- 忙しいですから (polite)
Both are correct. Plain form sounds more casual.
から vs ので
Both mean "because," but から is more subjective and casual. ので sounds softer and more polite. In everyday conversation, から is used more often.
