Pop Culture
Origin
Brainiac began as a fictional name, not an old scientific term. The name was created for the super-intelligent alien villain Brainiac, who first appeared in DC Comics’ Action Comics #242 in 1958. It was formed from brain with a name-like ending influenced by words such as maniac.
Language Root
Modern American English — brain + the ending -iac, modeled in part on maniac.
Original Meaning
The proper name of Brainiac, an extraordinarily intelligent extraterrestrial enemy of Superman.
Evolution Over Time
After Brainiac appeared in Superman comics, the memorable name became increasingly useful outside comics as a humorous label for an exceptionally intelligent person. Eventually lowercase brainiac entered informal English as a general term for someone considered extremely smart, intellectually gifted, or highly knowledgeable.
Modern Usage
An informal term for a very intelligent, knowledgeable, or intellectually talented person—sometimes admiring and sometimes teasing.

Narrative
Brainiac sounds as though it should have emerged from a psychology laboratory. It actually came from a comic book. In 1958, Superman encountered Brainiac, a technologically advanced alien possessing extraordinary intelligence. The character’s name combined the obvious association with brain and the punchy sound of words such as maniac. The name was so effective that it escaped fiction. People began calling exceptionally smart individuals “brainiacs,” eventually turning a supervillain’s name into ordinary vocabulary. Sometimes language evolves over centuries. Sometimes Superman helps do it.
