Here's a breakdown of its etymology:
* Old French: *capsizer*
* Middle English: *capsize*
The word was originally used to describe the act of overturning a boat or ship, and it later evolved to refer to the act of overturning any object.
Interestingly, the word "capsize" is related to the word "cap," which refers to the top of something. This connection makes sense because "capsizing" involves the top of a vessel being turned downwards.
