How to Say “Trust No One” in Japanese

誰も信じるな
dare mo shinjiru na
The English phrase 'trust no one' is translated into Japanese as 誰も信じるな (dare mo shinjiru na).
The phrase is used as a warning or command to avoid placing confidence in any person. It can be translated as 'don't believe anyone'.

What does it mean word for word?

The phrase is composed of 誰も, which literally means 'anyone' but translates to 'no one' when paired with a negative verb. 信じる, the dictionary form of the verb meaning 'to believe' or 'to trust'. And the particle な, which is attached to the end of a dictionary-form verb to create a strong negative command.

Is there a formal and an informal way to say it?

誰も信じるな is an informal, blunt and forceful command often found in fiction or dramatic warnings. For a more polite way to express the prohibition 'you must not trust anyone', use 誰も信じてはいけません. Additionally, the informal phrase 誰も信じちゃ駄目だ can be used to mean 'it's no good believing anyone'.

How does it change in a sentence?

To create a strong negative command, the particle な is attached to the end of a verb in its dictionary form, as seen in 誰も信じるな.

How do you pronounce it?

dare mo shinjiru na

Did you know?

  • The polite version 信じてはいけません uses the auxiliary いけません, which literally describes something that 'cannot go' or 'will not move forward'.
  • The command form ending in な is so blunt that using it in real life with a stranger or superior would be considered a severe social offense or an act of aggression.
  • The word 信じる comes from a root meaning 'faith' or 'belief', but it is often used interchangeably with 信じられない, which can mean both 'I cannot believe it' (surprise) and 'I cannot trust them' (suspicion).
