「それなら」If that is the case
If that is the case
The conjunction それなら can be seen as a combination of それ that followed by the auxiliary なら if.
Building on the previous information, それなら is mostly used in responses to statements made by others. In response to a statement A, it conveys the meaning of If that is the situation, then B or If that is the case then B. The speaker uses it to indicate that they will take action if the previously stated condition A is fulfilled.
A：電車、もう行っちゃったよ。
B：それなら、次のバスに乗ろうよ。
A: The train already left.
B: In that case, let’s take the next bus.
A：私、辛いもの苦手なんだよね。
B：それなら、こっちの料理にしようか。
A: I’m not good with spicy food.
B: Then how about this dish instead?
A：明日はちょっと忙しいかも。
B：それなら、明後日に変更しよう。
A: I might be busy tomorrow.
B: In that case, let’s reschedule for the day after tomorrow.
In contrast to simply using なら, the condition in それなら is established by what has been previously stated by the other speaker.
