## Meaning

To allow (someone) to act without constraint: to give (someone) free rein.

## Origin

Derived from the terminology of the stable, the expression refers to a rider relaxing the reins to allow a horse complete freedom of movement. By ceasing to restrain the animal's head, the rider permits it to set its own pace and direction, a transfer of control from the human to the beast that was later applied to general human conduct.
