覚え方のコツ Memory Tip
inaccuracy は accuracy「正確さ」に否定の in- が付いた形なので、まず accurate → accuracy → inaccuracy の並びで覚えると整理しやすいです。inaccurate が形容詞、inaccuracy が名詞。mistake が一回の『ミス』を指しやすいのに対し、inaccuracy は説明・数字・報道などが『正確でない状態や箇所』を広く言えます。factual inaccuracy, minor inaccuracies, due to inaccuracy のような実際のまとまりで覚えると、抽象語でも記憶に残ります。
Learn it as a family: `accurate`, `accuracy`, `inaccurate`, `inaccuracy`. The prefix `in-` makes it negative, so `inaccuracy` is the noun form for something not being exact. It often appears with facts, numbers, or reports, such as `minor inaccuracies`.

inaccuracy の語源・成り立ち Etymology
inaccuracy は in-「否定」+ accuracy から成り、accuracy はラテン語 accuratus「注意深い」にさかのぼります。語幹 cura は「配慮」で、accurate や curator も同根。つまり不正確さは、もとは「注意不足」の感覚です。
Inaccuracy combines the negative prefix in- with accuracy. Accuracy comes from Latin accuratus, meaning "careful" or "done with care," from cura, meaning "care" or "attention." So inaccuracy originally suggests a lack of carefulness; related English words include accurate, cure, and curator.
