defuse
UK: ˌdiːˈfjuːz | US: ˌdiːˈfjuːz
vt. to remove the fuse from (a bomb, etc.) to prevent explosion
vt. to reduce tension or danger in a situation
The word "defuse" combines the prefix "de-" (meaning "remove" or "reverse") with "fuse," referring to the cord used to ignite explosives. Originally literal (disarming bombs), it evolved metaphorically to describe calming volatile situations. The logic mirrors physically removing a fuse to prevent explosion, extended to diffusing conflicts.
