A person who creates or manages fireworks and other explosive displays.
The pyrotechnician carefully planned the fireworks show for the festival.
Pyrotechnician → It is formed from "pyro-" (from Greek "pur", meaning fire) and "technician" (from Greek "technē", meaning art or skill). The word refers to a skilled person who works with fire, particularly in creating fireworks or pyrotechnics.
Imagine a person skilled in the 'art' ('technē') of working with 'fire' ('pyro-') — that's what a pyrotechnician does.
