Thy tongue deviseth mischiefs. Ps. lii. 2.

The practice whereof shall, I hope, secure me from many mischiefs. Fuller.

The mischief was, these allies would never allow that the common enemy was subdued. Swift.

To be in mischief, to be doing harm or causing annoyance. -- To make mischief, to do mischief, especially by exciting quarrels. -- To play the mischief, to cause great harm; to throw into confusion. [Colloq.]

Syn. -- Damage; harm; hurt; injury; detriment; evil; ill. -- Mischief, Damage, Harm. Damage is an injury which diminishes the value of a thing; harm is an injury which causes trouble or inconvenience; mischief is an injury which disturbs the order and consistency of things. We often suffer damage or harm from accident, but mischief always springs from perversity or folly.
