覚え方のコツ Memory Tip
under-「不足して」＋ estimate「見積もる」に -ing が付いた形で、estimate の語末 e を落として作ります。「下で見積もる」図を思い浮かべ、実際の費用・能力・危険・難しさより低く判断することと覚えます。underestimating the cost や avoid underestimating an opponent が典型です。
Break the form into under-, estimate, and -ing. Here under- means “too little,” so underestimating is estimating something below its real amount, power, difficulty, or importance. The final e of underestimate is dropped before -ing is added. Picture a budget that looks cheap but later doubles, or an opponent who seems weak but performs strongly. Common combinations include underestimating the cost, underestimating the difficulty, and underestimating another team. The opposite direction is overestimating, judging something as greater than it really is.

underestimating の語源・成り立ち Etymology
underestimating は under「下に・不十分に」+ estimate「評価する」+ -ing から成る形です。estimate はラテン語 aestimare「価値を見積もる」にさかのぼり、「本来より低く見積もる」から過小評価の意味になります。関連語に esteem、overestimate があります。
Underestimating is formed from underestimate plus -ing, with the final silent e removed. Underestimate combines English under-, used here in the sense “insufficiently” or “below the true amount,” with estimate. Estimate entered English from Latin aestimare, meaning to value, appraise, or assess. The compound therefore means assigning a value or degree lower than reality warrants. The -ing form serves as a present participle in progressive constructions or as a gerund naming the act.
