KK: /ɛkˌskruːʃiˈeɪʃən/
A state of intense suffering or pain, often described as unbearable.
The excruciation from his injury made it difficult for him to concentrate.
Excruciation → It is formed from "ex-" (meaning out of or from) and "cruciare" (meaning to torture or torment). The word describes a state of extreme pain or suffering that feels as if one is being tortured.
Think of being 'tortured' ('cruciare') in a way that feels like it's coming 'out of' ('ex-') you — that's why excruciation means intense suffering.
