Root Explanation

Ultrahigh → It is formed from "ultra-" (meaning beyond or extreme) and "high" (meaning elevated or tall). The word "ultrahigh" refers to something that is extremely high or beyond the usual height.

Memory Tip

Think of 'ultra-' meaning beyond, and 'high' meaning tall — so ultrahigh describes something that is extremely tall.
