Root Explanation

Ultraheavy → It is formed from "ultra-" (meaning beyond or extreme) and "heavy" (from Old English "hefig", meaning having great weight). The word "ultraheavy" describes something that is extremely heavy or beyond the usual weight.

Memory Tip

Think of 'ultra-' meaning beyond, and 'heavy' referring to weight — so ultraheavy means something that is beyond heavy.
