bit one's tongue

Held back speech

To bite one's tongue is to hold back words you want to say—usually criticism, disagreement, or information that might cause trouble.

The image is of physically restraining speech: I wanted to tell him he was wrong, but I bit my tongue.

It implies self-control in the face of provocation or the temptation to speak unwisely.
