Usage

What does regenerate mean? Regenerate means to renew or restore something, especially after it has been damaged or lost. The act or process of regenerating is regeneration. Both terms are commonly used in the context of biology to refer to the regrowth of part of an organism or environment. In this sense, a close synonym is regrow. 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. Regenerate can also be used in other specific ways. In the context of religion, regenerate can mean to be spiritually reborn. In chemistry, to regenerate is to restore or be restored to an original physical or chemical state. In audio electronics, regenerate means to increase amplification through a kind of feedback process. Much less commonly, regenerate can be used as an adjective meaning restored, renewed, reborn, or morally reformed. Example: It is hoped that the experimental treatment will reduce healing time by helping tissue to regenerate more quickly.

Etymology

Origin of regenerate

1425–75; late Middle English (adj.) < Latin regenerātus, past participle of regenerāre to bring forth again, equivalent to re- re- + generātus; see generate

Explanation

Starfish are famous for their ability to regenerate, or regrow, a lost arm. Anything that revives in this magical way can be said to regenerate. While the verb regenerate can literally mean "produce anew," it can also describe what happens when something is fixed up, made "like new." An argument that's often made for bringing a new company, sports complex, casino, or other enterprise to a depressed area is that it will regenerate the town economically, bringing it back to life. In Latin, regeneratio means "being born again."
