慎む”tsutsu shimu” vs. 謹む”tsutsu shimu”: They Sound Absolutely Same But..

Two verbs written in different kanji but pronounced exactly the same — this is one of the trickiest challenges in Japanese. 慎む（つつしむ） and 謹む（つつしむ） both sound like tsutsushimu, yet they carry different nuances. Mixing them up in a formal setting can send the wrong message entirely.

Yuka

Rei, I just wrote a thank-you card and used 謹む to mean ‘I will be careful.’ Was that right?

Rei

Actually, 慎む is usually the one that means ‘to be careful or restrained in behavior.’ 謹む carries a more formal, respectful meaning — like ‘to act reverently.’ Easy to mix up since they sound identical!

At a Glance

慎む (tsutsushimu) — Restraint and Caution

The verb 慎む（つつしむ） means to hold oneself back, to be prudent, or to abstain from something. It describes a deliberate choice to control one’s behavior, speech, or habits. You will hear it in everyday advice, workplace guidance, and health-related contexts.

お酒を慎むようにしています。
Osake wo tsutsushimu you ni shite imasu.
I try to hold back on alcohol.

言葉を慎んで話してください。
Kotoba wo tsutsushinde hanashite kudasai.
Please be careful with your words.

彼は食べ過ぎを慎んでいる。
Kare wa tabesugui wo tsutsushinde iru.
He is restraining himself from overeating.

Yuka

So 慎む is about self-control — like telling yourself to hold back on something?

Rei

Exactly! Think of it as placing a brake on your own actions or words. It is very practical and used in daily life.

謹む (tsutsushimu) — Reverence and Formal Respect

The verb 謹む（つつしむ） conveys deep reverence and respectful conduct. It appears most often in formal written greetings, ceremonial announcements, and situations where one shows deference. You will see this kanji frequently in New Year’s cards and official statements.

謹んでお祝い申し上げます。
Tsutsushinde oiwai moushiagemasu.
I offer my most respectful congratulations.

謹んでご冥福をお祈りいたします。
Tsutsushinde goimeifuku wo oinori itashimasu.
I humbly pray for the repose of the soul.

謹んで新年のご挨拶を申し上げます。
Tsutsushinde shinnen no goaisatsu wo moushiagemasu.
I respectfully offer my New Year’s greetings.

Yuka

These 謹む phrases all sound very formal and official. I would not use them in casual conversation, right?

Rei

Correct. 謹む is almost exclusively found in formal writing or ceremonial speech. In daily conversation, you would never say 謹んで to a friend.

Usage Tips: When to Write Which Kanji

Because these two words sound identical, writers must rely on context to choose the correct kanji. Ask yourself: am I describing self-restraint or caution (use 慎む) or formal reverence toward others (use 謹む)? A useful memory trick: 謹む contains the kanji 言 (speech/words) inside, hinting at its use in carefully worded formal statements. 慎む contains 心 (heart/mind), hinting at controlling one’s inner impulses.
