Root Explanation

Weightlessness → It is formed from "weight" (from Old English "wiht", meaning mass or heaviness) and "-lessness" (meaning without). The word "weightlessness" refers to the state of having no weight or being without heaviness.

Memory Tip

Think of being 'without' ('-lessness') any 'mass' or 'heaviness' ('weight') — that's what weightlessness means.
