Root Explanation

Blastoff is formed from "blast" (from the Old English *blæst*, meaning a strong gust of wind or explosion) and "off" (meaning away or from). The term describes the moment when a spacecraft is propelled away from the ground, often with a strong force or explosion.

Memory Tip

Think of a strong 'gust' or 'explosion' ('blast') that sends something 'away' ('off') — that's what blastoff means.
