cern
ケルン
覚え方のコツ Memory Tip
cern は日常語として単独使用する語というより、ラテン語 cernere「分ける、見分ける」に結び付く語根として捉えます。discern では dis- と結び付き「見分ける」、concern などでは長い歴史の中で形と意味が発展しました。「選り分けて判断する」という核を押さえるのが安全です。
Treat cern here as the name of a historical root, not as a word you would normally use by itself in modern conversation. Its central image is sorting things apart so that a distinction or decision becomes possible. The clearest practical connection is discern, meaning to recognize or distinguish something. Remembering the sequence cern inside discern helps preserve that core idea. Other related words have undergone substantial changes in form and meaning, so use the root as an etymological guide rather than assuming that every word containing similar letters has the same modern sense.

cern の語源・成り立ち Etymology
cernはラテン語の動詞cernere（分離する・見分ける）に由来します。「区別・決定する」意味の語根を基とし、discern（識別する）やcertain（確かな）の核心部分です。本来は語根形ですが、「違いを区別して確定する」という原義が派生語の意味を理解する鍵となります。
The root cern is associated with Latin cernere, meaning to separate, sift, distinguish, perceive, or decide. Through Latin compounds and later French and English development, this root contributed to words such as discern. Related Latin forms also lie behind certainty and decision-related vocabulary, although their spellings have changed considerably. In modern English, cern is best treated as an etymological root label rather than a productive independent noun used in general speech.
