concussion
kuhn-KUSH-uhn
/kənˈkʌʃən/
Temporary unconsciousness or confusion caused by a blow to the head.
Specifically refers to a mild traumatic brain injury (TBI) resulting from a sudden impact or violent shaking of the head, affecting brain function temporarily.
The story behind the word. The word 'concussion' comes from the Latin verb 'concutere,' meaning 'to shake violently' or 'to strike together.' This verb is formed from 'com-' (together, with) and 'quatere' (to shake). It entered English in the 15th century, referring to a violent shock or shaking. By the 17th century, it specifically denoted the medical condition resulting from a blow to the head, where the brain is 'shaken' within the skull.
