わけだ

N3Other

N3 · Other · plain form + わけだ

Meaning

no wonder; that explains why...

Structure

plain form + わけだ

Explanation

わけだ presents a natural conclusion from the facts given before it, similar to “no wonder” or “that explains why.”

Usage

Use it when you understand the reason and summarize the natural result, often with a “now I see” nuance.

Example

昨日ほとんど寝ていないんですか。それで今日は眠いわけですね。

You barely slept yesterday? That explains why you are sleepy today.

Common Mistake

Do not treat わけだ as a simple です; it emphasizes that the result follows from a reason.

Memory Tip

When a reason appears first, わけだ summarizes the natural result.
