regenerative

/ˌriˈʤɛnərətɪv/

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."
