sa·vant /saˈvän(t),säˈvän(t)/

"Savant" comes from the Latin "sapere" ("to be wise") by way of Middle French, where "savant" is the present participle of "savoir," meaning "to know."

"Savant" shares roots with the English words "sapient" ("possessing great wisdom") and "sage" ("having or showing wisdom through reflection and experience").

The term is sometimes used in common parlance to refer to a person who demonstrates extraordinary knowledge in a particular subject, or an extraordinary ability to perform a particular task.
