Etymology

Origin of lockjaw

First recorded in 1795–1805; lock 1 + jaw 1

Explanation

The serious disease called Tetanus is often referred to as lockjaw. In most parts of the world, people are regularly vaccinated against lockjaw. Tetanus has long been popularly called lockjaw because one of the disease's earliest effects is muscle spasms in the jaw that can "lock" it closed. Lockjaw is the result of an open wound being infected with a particular strain of bacteria, and it's found in medical history as far back as the fifth century BCE. Without proper immunization or treatment, lockjaw can be deadly.
