Questions & Answers about koko wa kinen da kara, soto nara daijoubu desu.

What does なら mean in 外なら, and how is it different from たら?

なら marks a conditional based on a given option or context: “as for outside / if it’s outside (that option), [it’s fine].” It often picks one case out of several possibilities and comments on it.

Differences:

• なら: conditional tied to a topic or previously mentioned idea. As for X, Y. 外なら大丈夫です = As for outside, it’s okay.
• たら: event/temporal “if/when.” 外に出たら大丈夫です = Once you go outside, it’ll be okay.
• と: logical/result or habitual condition; too stiff for this nuance.

Why is there だ before から in 禁煙だ から?

禁煙 is a noun. When a noun or na-adjective directly precedes から in plain style, you need the copula だ:

• Noun + だ + から: 禁煙だから (because it’s non-smoking)
• Na-adjective + だ + から: 静かだから (because it’s quiet)

If you want to stay fully polite there, use ですから: 禁煙ですから.

Is it okay to mix plain だ and polite です in the same sentence?

Yes, very common. Subordinate clauses (like …から) often use plain form, while the sentence ends politely: ここは禁煙だから、外なら大丈夫です。 If you prefer full politeness, use: ここは禁煙ですから、外なら大丈夫です。

Could I use ので instead of から? Any nuance difference?

Yes:

• ここは禁煙なので、外なら大丈夫です。
• ここは禁煙ですので、外なら大丈夫です。 (more polite)

Nuance: ので sounds a bit softer and more explanatory; から is more direct and conversational.

Why is it ここは and not ここで?
