What is the meaning of word extant?

"Extant" means still existing; surviving. It's often used to describe something that has survived from the past, like:

* Extant manuscripts: Ancient writings that have been preserved.

* Extant species: Animals or plants that still exist in the wild.

* Extant ruins: Structures from a past civilization that are still standing.

Think of it like "existing" but with an emphasis on surviving through time.
