Same family: explosive, exploded, exploding, exploder, explosively. If you can spell one, the shared part carries to the others.

Where it comes from: “Explosion” comes from the Latin word “explodere,” which originally meant ‘to drive out by clapping’ (as crowds would clap actors off the stage). Over time, it came to mean a loud, violent outburst, and later the physical bursting we think of today.
