Root Explanation

Liftoff is formed from "lift" (from Old English "lyft", meaning to raise or elevate) and "off" (meaning away or from). The word describes the action of raising something away from the ground, particularly in the context of a spacecraft or rocket.

Memory Tip

Imagine something being 'raised' ('lift') and then 'moving away' ('off') from the ground — that's what liftoff means.
