Not Really a Conditional
なら looks like the other conditionals but behaves differently. It picks up something already mentioned and responds to it.
- A: 日本に行きます。(I'm going to Japan.)
- B: 日本なら、京都がいいですよ。(Japan? Then Kyoto is good.)
B is not supposing anything. B is saying "given that topic, here's my advice."
Formation Is the Easiest of the Four
Attach なら to the plain form or a bare noun — no conjugation:
| Type | Form |
|---|---|
| Noun | 日本なら |
| な-adjective | 暇なら |
| い-adjective | 安いなら |
| Verb | 行くなら |
The Order Reversal
This is what really separates なら from たら:
| Sentence | Which happens first? |
|---|---|
| 日本に行ったらカメラを買います | Go first, then buy (buy it there) |
| 日本に行くならカメラを買います | Buy first, then go (buy it before leaving) |
なら can put the second clause before the first in time. No other conditional does that.
Giving Advice
Because なら responds to what someone said, it is the natural frame for advice:
- 日本語を勉強するなら、毎日少しずつがいいです。
- 安いのが欲しいなら、あの店へどうぞ。
