Plural of dynamite (a powerful explosive made with nitroglycerin); also a verb meaning to blow something up with dynamite or to be amazingly good at something.
From Greek dynamis (power) + -ite (mineral/chemical suffix). Alfred Nobel coined the term in 1867 when he stabilized nitroglycerin with kieselguhr, creating the first practical stick explosive.
Dynamite was revolutionary because it made explosives safe enough to handle—before this, nitroglycerin was so unstable that Nobel's own brother died in an accident testing it, driving Nobel to find a solution.
