Environments that have been damaged or destroyed, like forests or grasslands damaged by fire, can also regenerate.

Regenerate can also be used in other specific ways.

Where does regenerate come from?

The first records of the word regenerate come from the 1400s. It ultimately comes from the Latin verb regenerāre, meaning “to bring forth again.” The prefix re- means “again” and generate means “to produce or bring into existence.”

In the natural world, plants and animals regenerate in many different ways. Some plants can regrow from a single part—such as when you plant a chunk of carrot or potato and it sprouts again. Some simple organisms, like the hydra, can regenerate even after being torn apart. In humans, hair and skin are always regenerating, but even some organs are able to regenerate, such as the liver and the lungs.

The more figurative uses of regenerate often liken the regrowth of something—such as a city or community—to the regrowth of a body part.
