Ultracritical → It is formed from "ultra-" (meaning beyond) and "critical" (from Greek "kritikos", meaning able to judge). The word "ultracritical" means going beyond normal criticism, often implying an excessive or extreme level of judgment.
Think of 'beyond' ('ultra-') and 'able to judge' ('kritikos') to remember that 'ultracritical' refers to an extreme level of judgment.
