Pyrotechnical → It is formed from "pyro-" (from Greek "pur", meaning fire) and "technical" (from Greek "techne", meaning art or skill). The word refers to the art or skill related to fire, particularly in the context of fireworks and explosive devices.
Think of 'fire' ('pyro-') and the 'art or skill' ('technica') involved in creating fireworks. This helps you remember that 'pyrotechnical' relates to the skill of working with fire.
