Savant

From Freepedia

A savant (suh-VAHNT) is a learned person, well versed in literature or science, often with an exceptional skill in a specialized field of learning.

The term is also commonly used as an abbreviated term for autistic savant, formerly termed an idiot savant.

The word comes from the French word savant [savɑ̃], meaning scientist (literally, knowing).

A savant can sometimes simply be a person who uses more of their brain. Some people become savants after some sort of injury.
