Because with ので
ので also means "because," just like から. It sounds softer and more polite, so it's the one you'll hear more in formal situations and when talking to strangers. Our lesson on conjunctions covers both ので and から with more context.
How to Connect
Verbs and い-Adjectives
Use the plain form + ので:
- 雨が降るので (because it will rain)
- 寒いので (because it's cold)
な-Adjectives and Nouns
Add な before ので:
- 静かなので (because it's quiet)
- 誕生日なので (because it's my birthday)
With Polite Form
ので can also follow the polite form (ますので, ですので) for extra formality. This is common in announcements and business settings.
ので vs から
| ので | から | |
|---|---|---|
| Tone | Soft, objective | Direct, subjective |
| Formality | More polite | More casual |
| Best for | Explanations, apologies, requests | Casual conversation, strong opinions |
