- 1天才；超級聰明的人（美式口語，常帶一點書呆子、漫畫味）。
A brainiac is someone very, very intelligent — often the science-and-puzzles kind, the person who loves hard problems and finishes them fast. Informal, and it feels especially American. Friends may say it with a grin; it can praise, and it can also tease, almost like nerd, putting someone in a “too into books” box. A formal paper would probably say brilliant or highly intelligent instead. The word was coined as the name of a Superman villain in Action Comics #242 in July 1958. It is a blend of brain and maniac, with a nod to ENIAC, an early computer; on the surface it can also look like brainy + -ac. So a comic-book name walked out into everyday talk. You do not need the comic to use it. Though actually, it does not mean the person is mad, even though maniac sits inside the word — it means their brain is the wild part.
組成Blend of brain + maniac, with influence from ENIAC, an early computer. Coined as the Superman villain Brainiac in Action Comics #242 (July 1958). By surface analysis, brainy + -ac.
