Make It Stick

  • Think of "pellucid" like "clear" (A1 word), but much stronger—like glass or pure water that you can see perfectly through
  • Picture a clear mountain lake where you can see the stones at the bottom without any dirt or cloudiness
  • It's the feeling when someone explains something so simply that you understand it right away, no confusion
  • Sounds like "peh-LOO-sid" → imagine a "loo" (bathroom) so clean and clear you see everything inside perfectly
  • Think of a crystal-clear diamond or a clean window that lets all the light through without any dirt
  • NOT like "clear" (which can be general), "pellucid" means perfectly clear, almost shining with clarity
  • NOT like "muddy" or "cloudy" which block your view; pellucid is the opposite—pure and transparent
  • NOT like "complicated" or "confusing," but very simple and easy to understand

Try Other Words

  • Transparent: allowing light to pass through so you can see clearly (Use when talking about physical objects like glass or water)
  • Crystal-clear: very clear and pure (Use in informal speech to describe water, explanations, or images)
  • Lucid: clear and easy to understand (Use mainly for ideas, explanations, or thoughts)

Unboxing

  • Word parts: "pel-" (from Latin root related to "through") + "lucid" (clear, light)
  • Etymology: From Latin "pellucidus," meaning "allowing light to pass through," literally "through light"
  • Historical development: Used since the 1600s in English to describe clear liquids or writing that is easy to see or understand
  • Modern usage: Used in literature and formal speech to describe perfect clarity in appearance or meaning
