Usage
What does regenerative mean? Regenerative means able to or tending to regenerate—to regrow or be renewed or restored, especially after being damaged or lost. The act or process of regenerating is regeneration. Regenerative is most commonly used in the context of biology to describe the properties of organisms or environments that are capable of regrowth. In animals, tissue, organs, or other body parts that have been injured or lost are sometimes regenerated. In some animals, regeneration happens on an even greater scale, with some being able to regrow an entire limb or tail. Environments that have been damaged or destroyed, like forests or grasslands damaged by fire, can also regenerate. Such things are said to have regenerative properties. Regenerative is also commonly used in a figurative way to describe actions that are intended to renew or restore. Example: Scientists are studying the regenerative properties of the hydra in hopes of shortening the healing process after injuries.

Etymology
Origin of regenerative
First recorded in 1350–1400; Middle English word from Medieval Latin word regenerātīvus. See regenerate, -ive
Explanation
When something is regenerative, it has a ability to regrow or become better. A salamander's tail is regenerative — if it falls off, it can regrow! Animals with regenerative abilities, like starfish and some lizards, don't have to worry about losing body parts; they just form new ones. In farming, regenerative practices involve growing crops in a way that the environment is improved, with more nutrients in the soil and cleaner air and water. The Latin root of regenerative is regenerare, "bring forth again."
