📚 Will-o'-the-wisp, noun. 🔉 /wɪləðəˈwɪsp/ 🇬🇧 ❓ Definition: A phosphorescent light seen hovering or floating at night on marshy ground, thought to result from the combustion of natural gases. ❗️ Examples: 1. Pale blue light, the colour of Egewe's hair or a will-o'-the-wisp, filled the room. 2. When lit, the cloth can be made to dance like a will-o'-the-wisp in the dark - a stunt that would definitely not amuse a modern fire marshal. 3. I saw it now, a dull orange will-o'-the-wisp bobbing and winking through the trees. 4. And yet if a writer succeeds in catching the will-o'-the-wisp she will go on existing, elusive and transformed, in the character she has created. 5. As the years passed, he became even more of a will-o'-the-wisp; not to be pinned down; difficult to track. ━━━━━━━━━━━━━ 🌀 @cambridge_dic
