Root Explanation
Misestimation → It is formed from "mis-" (meaning wrongly) and "estimation" (from Latin "aestimatio", meaning valuation or assessment). The word "misestimation" means a wrong or inaccurate assessment of something.
Memory Tip
Think of making a 'wrong' ('mis-') 'valuation' ('aestimatio') — that's why misestimation refers to an incorrect assessment.
