〜もしないで: meaning and usage

How to form it

• verb (masu-stem)+もしないで/もせずに
• noun+もしないで/もせずに

How it is used

'Without even doing A': criticises someone for skipping the most basic step. It follows a masu-stem or a する-noun such as 「確認」 or 「努力」; 「〜もせずに」 is the written form. Stronger and more critical than plain 「ないで」.

Examples

1. 努力もしないでよい結果は期待できない。

   Without effort, you can't hope for good results.

2. 彼は中身を確かめもしないで、書類にはんこを押した。

   He stamped the document with his seal without even checking what it said.

3. 味見もしないで客に出すなんて、料理人として失格だ。

   Anyone who serves food to customers without even tasting it doesn't deserve to be called a cook.
