IPA: /ˈbreɪnˌkeɪs/
KK: /ˈbrenˌkes/
The part of the skull that surrounds and protects the brain.
The doctor examined the braincase for any signs of injury.
Braincase → It is formed from "brain" (from Old English "brægen", meaning the organ of thought and intelligence) and "case" (from Latin "capsa", meaning a container). The word "braincase" refers to the container or structure that encases the brain.
Think of the 'brain' as the organ of thought being protected by a 'case' — that's why 'braincase' means the structure that encases the brain.
