What does detonating mean?
"Detonating" is the present participle of the verb "detonate," meaning to explode suddenly and violently, or to cause such an explosion. It can describe an explosive itself going off — as when buried charges go detonating under a bridge — or the act of setting off a device, as in a bomb squad safely handling a detonating mechanism. The word comes from the Latin detonare, meaning "to thunder down," formed from de- and tonare, "to thunder," which makes its sense aptly vivid: a detonation is a burst of man-made thunder. In usage, "detonating" tends to appear in technical, military, journalistic, or scientific contexts rather than casual conversation, and it connotes suddenness, force, and danger. It should not be confused with the similar-sounding "denoting," which simply means indicating or signifying.

Etymology of detonating
The word derives from the Latin verb detonare, meaning "to thunder down," combining the prefix de- with tonare, "to thunder." It entered English in the late 16th or early 17th century, initially as a rare or technical term before becoming standard in discussions of explosives. It shares its Latin root with words such as "astonish" (via Vulgar Latin *extonare, "to thunder out") and, more distantly through the Indo-European root *(s)ten-, with the native English word "thunder."
