覚え方のコツ Memory Tip
by + 名詞 + of で「〜によって」の骨格をまず押さえると覚えやすい。ふつうの by means of より硬く、努力・根気・工夫で何とか達成した感じが出るのが by dint of。単なる原因ではなく「その力を使って勝ち取った」響き。by dint of hard work, by dint of persistence のような組み合わせで覚えると定着しやすい。because of のように原因を広く述べる語ではない点にも注意。
Remember `dint` together with effort words like `hard work` and `persistence`. The phrase often appears in `by dint of hard work`, so it suggests achieving something through strong effort, not just because of a simple cause. It is much narrower and more formal than `because of`.

by dint of の語源・成り立ち Etymology
dintは古英語dynt（打撃、一撃）に由来。古ノルド語dyntrとも関連する。元は「力強い一撃」を意味し、転じて「力・努力」の意味に。by dint ofで「〜という打撃＝力によって」が原義。関連語：dent（へこみ）はdintの変形。
"Dint" comes from Old English "dynt," meaning a blow or strike, and it is related to Old Norse "dyntr." It first meant the force of a physical hit, then widened to mean strength, effort, or pressure more generally. So "by dint of" originally meant by force, and later came to mean by means of hard effort. "Dent" is a related form of the same word.
