undifferentiated
未分化な
解説 Definition
まだ特定の特性や役割に分化していない状態を指します。基本的でありながら、明確な区別や専門化がされていない性質を表します。
Undifferentiated means not clearly separated into different types, parts, or forms. It is often used in biology, medicine, or analysis when something is still basic, general, or not yet developed into distinct categories.
覚え方のコツ Memory Tip
まず differentiated を「違いがはっきりした・役割が分かれた」と押さえる。different, difference, differentiate と同じ差のグループだと見抜ければ、核は「区別される」。そこに否定の un- が付くので undifferentiated は「まだ区別も専門化もされていない」。特に undifferentiated cells でよく見かけるので、「何の細胞になるかまだ決まっていない状態」を思い浮かべると強い。indifferent(無関心な)とは別語なので混同しないこと。
Start with `different`, then `differentiate` means develop into different types. Add `un-`, and the word means the process has not happened yet. Remember the common pair `undifferentiated cells` to lock in the idea of an early, not-yet-specialized stage.

undifferentiated の語源・成り立ち Etymology
undifferentiatedはun-「〜でない」+differentiated。核のdifferはラテン語differre「運び分ける・別々にする」に由来するので、全体で「まだ区別されていない」から「未分化な」となります。関連語はdifference, differentiate。
This word is built from `un-` meaning "not" and `differentiated`. The core comes from Latin `differre`, meaning "to carry apart" or "to set apart," which gave English `difference` and `differentiate`. The idea developed from things being separated into distinct kinds to things not yet separated or distinguished.
