Idiom B1 Informal

Bite your tongue

To stop yourself from saying something you would rather not say

Meaning

Bite your tongue — To stop yourself from saying something, especially a comment that is critical, rude, or hurtful, choosing to stay silent rather than speak your mind.

Origin & History

The idiom comes from the literal act of holding the tongue between the teeth to physically prevent yourself from speaking. This vivid, painful image makes the meaning instantly clear: if your tongue is between your teeth, you simply cannot talk. The expression has been used in English to mean staying silent for many centuries.

The phrase appears in early English literature, including Shakespeare's Henry VI, where a character is urged to 'bite his tongue' rather than speak rashly. Its long history in print helped fix the expression in everyday English, and today it is one of the most recognised idioms for self-restraint in speech.

How to Use It

This idiom is mainly informal and common in conversation, storytelling, and informal writing. It usually follows the pattern subject + bite + possessive + tongue, as in I bit my tongue or she bites her tongue. The possessive adjective changes to match the speaker (my, your, his, her, their). It often implies a deliberate effort to avoid saying something hurtful or unwise, and may suggest the speaker is frustrated but choosing to stay polite.
