The phrase's origin

The phrase 'defend tooth and nail' is used to describe someone's commitment to defending themselves from physical or verbal attacks. It suggests giving everything you have to win or succeed, or defending your opinion, rights or possessions with determination and zeal. The phrase comes from the imagery of a wild beast in a fierce battle, using its teeth and nails (or claws) as weapons.

The earliest known use of this expression in print was in the 1560s, but its roots can be traced back to the Latin phrase 'toto corpore atque omnibus ungulis', meaning 'all the body and every nail'. The phrase was used in Sir Thomas More's 'In a Dialogue of Comfort and Tribulation' in 1535, but it didn't really take off until the 1700s.
