differentiating の語源・成り立ち Etymology
ラテン語のdifferre（接頭辞dis「離れて」+ 語根ferre「運ぶ」）に由来します。元々「物を離して別々に運ぶ」イメージから、対象の特徴を分けて見極め「区別する」という意味に発展しました。同語根を持つ単語にdifference（違い）やtransfer（移動する）があります。
Differentiating is formed from differentiate by dropping its final silent e and adding -ing. Differentiate was built from Medieval Latin differentia, meaning “difference,” which is related to Latin differre, “to carry apart” or “to differ.” Differre combines dis-, expressing separation, with ferre, “to carry.” The historical image of things being carried apart developed into the modern idea of recognizing or creating distinctions between them.
