noun
demise
dih-MYZE/dɪˈmaɪz/
The final end of someone or something.

Etymology
The pieces mean 'put away,' but the noun first referred to transferring property, then sovereignty. Because a ruler's death could occasion that transfer, demise came to mean death and, more broadly, an end or failure.
In context
forcefully shoved him into a chair which in turn broke his hip and led to his demise
