What does regenerator mean?
A regenerator is something that has the capacity to restore itself or replace lost, damaged, or worn-out parts. The word can describe an organism such as a starfish, a body part such as the liver, or regenerative tissue used in medicine. Its defining feature is regrowth rather than simple repair: the original structure is not merely patched but can be rebuilt to some degree. In regenerative medicine, “regenerator” is used especially as a modifier, as in “tissue regenerator,” while related forms such as regenerate, regeneration, and regenerative are far more common in general English. Although the noun has a straightforward meaning, its specialized medical uses require caution because regenerative capacity differs greatly among tissues and organisms.
nounA person, organism, organ, tissue, or other thing capable of regenerating lost or damaged parts. In medicine, the term may also refer to tissue that has the capacity to regrow.
- Something that regenerates or restores lost, damaged, or worn-out parts.
- An organism, organ, or body part capable of regrowing tissue or replacing itself.
- In regenerative medicine, tissue or an organ whose growth can restore damaged or lost tissue.

"Researchers compared several natural regenerators to identify the cellular mechanisms they share."
A regenerator does more than replace what is lost: it has the remarkable ability to grow it again.

Where does regenerator come from?
Regenerator is derived from Latin regenerator, a noun meaning “one who restores or regenerates,” formed from regenerare, “to restore, renew, or reproduce.” The Latin verb combines the prefix re-, meaning again, with generare, “to beget or produce,” and it is the source of the familiar English family regenerate, regeneration, and regenerative. The English noun is attested from the early 19th century and was initially used more broadly for a restoring agent or principle before acquiring its technical associations with biological regrowth.
