illuminating
照らす
解説 Definition
illuminating は illuminate（照らす）の現在分詞・動名詞です。光で場所や物を明るくしている動作を表し、「啓発的な」という形容詞の意味と混同しないようにします。
The present participle of “illuminate,” meaning to be shining light on a place, object, or person so that it becomes brighter or more visible. In this verbal use, it describes an action in progress rather than the adjectival sense “informative or revealing.”
覚え方のコツ Memory Tip
原形 illuminate の語末の e を取って -ing を付けた現在分詞で、/ɪˈluːməneɪtɪŋ/ と発音します。lamp is illuminating the desk のように「光源＋be illuminating＋対象」で覚えましょう。形容詞なら「理解を深める、有益な」なので文の構造で区別します。
Illuminating is formed from illuminate by dropping the final silent e and adding -ing. It is pronounced /ɪˈluːməneɪtɪŋ/. Connect it with the pattern “a light is illuminating something”: a lamp illuminates a desk, path lights illuminate a walkway, and a screen illuminates a face. This clear image keeps the physical meaning in mind. The same spelling can be an adjective meaning “informative” or “revealing,” but an object after the word, such as “illuminating the desk,” identifies the ongoing action of casting light.
例文

illuminating の語源・成り立ち Etymology
ラテン語 illuminare（光を当てる）から。in-（中へ）+ lumen（光）が語根で、「内側から光で満たす」が原義。関連語：luminous（光る）、illuminate（照明する）。物理的な照明から比喩的に「知識で照らす・啓発する」意味にも広がった。
Illuminating is the -ing form of illuminate, which entered English through Latin illūmināre, “to light up.” That verb combines the assimilated prefix in-, suggesting movement into or upon, with lūmen, “light.” The literal meaning of filling or covering something with light produced the physical sense used here. English later developed the figurative sense of making an idea clearer, but this entry concerns actual light shining on something.
