Idiom B2 Informal / Semi-formal

Throw caution to the wind

To act recklessly; to abandon care and do something risky without worrying about the consequences

Meaning

Throw caution to the wind — To act recklessly; to abandon care and prudence and do something bold or risky without worrying about the possible consequences.

Origin & History

The idiom is a variant of older expressions such as throw to the winds, meaning to abandon, cast away, or get rid of something completely. The phrase to the winds — describing something scattered so widely it cannot be gathered back — has been used for centuries, including by writers such as John Milton.

From this vivid image of casting something away to be scattered and lost, the figurative sense developed: to throw caution to the wind is to deliberately let go of care and prudence, allowing recklessness to take their place. The modern fixed form pictures caution itself being flung away on the breeze, never to be recovered.
