Morphology

brainiac = brain (transparent) = brain + iac

Formed by 'brain' + the agentive/characterizing suffix '-iac', so learners can infer 'a person with brain' → very intelligent.

Etymology

The word brainiac comes from the word brain plus the ending -iac, like in maniac, and it gives the image of someone 'crazy about thinking'. So, a brainiac is a person who is very clever and good at thinking.
