Did You Know?

Posterior comes from the Latin word posterus, meaning "coming after". Posterior is often used as a technical term in biology and medicine to refer to the back side of things, and is the opposite of anterior, which refers to the front side. For example, as more people took up running as a sport, doctors began to see an increase in stress fractures along the posterior as well as the anterior surface of the lower leg bones. In some technical fields, posterior may mean "later". When used as a noun, posterior simply means "buttocks".
