Resembling or characteristic of fireworks; showy, explosive, or spectacular in appearance or effect.
Modern English compound: 'firework' plus informal adjective-forming suffix '-y' (from Old English '-ig'). The suffix creates a descriptive term suggesting qualities similar to fireworks.
Adding '-y' to nouns is one of English's most playful word-building tricks—'fireworky' lets you describe anything dramatically explosive or showy, from a bright personality to a colorful sunset, without being too formal.
