Word: luminous (adjective)

Associations

"Luminous" means something that gives off light or shines brightly. It is often used to describe things that glow in the dark or are very bright.

• The stars are luminous in the night sky. Here, "luminous" shows that stars shine with light.

A well-known synonym is "bright." The difference is that "bright" can mean strong light or intelligence, while "luminous" specifically means giving off light or glowing.

Substitution

You can use:

• "glowing" — means softly shining, often with warmth.
• "radiant" — means shining brightly, often with happiness or beauty.
• "shining" — general word for giving off light.

Using "glowing" instead of "luminous" makes the light seem softer. Using "radiant" adds a feeling of beauty or happiness.

Deconstruction

• Root: "lumin" means light (from Latin "lumen").
• Suffix: "-ous" means "full of" or "having." So "luminous" literally means "full of light" or "having light."

Inquiry

• Can you think of something in your room that is luminous?
• How is a luminous object different from something that just reflects light?
• Have you ever seen a luminous animal or plant? What was it like?
