KK: /ˈsuːpərˌwɛpən/
A very powerful weapon that is often more advanced than regular weapons.
The military developed a superweapon that could change the course of the war.
Superweapon → It is formed from "super-" (meaning above or beyond) and "weapon" (from Old English "wæpen", meaning instrument of fighting). The word "superweapon" refers to a weapon that is above or beyond ordinary capabilities, often implying extreme power or effectiveness.
Think of something that is a 'weapon' but 'above' ('super-') the usual level of power — that's what a superweapon is.
