🧪Kryptonite: What’s what?
We all have a weakness. For Superman, it’s kryptonite—a glowing green rock from his destroyed home planet. For the rest of us, it’s maybe chocolate. Or procrastination. Or spoilers.
This month, we’re breaking down a word that started in comics but now lives everywhere—from science to slang. Whether you’re a superhero in disguise or just trying to survive your day, kryptonite is a word worth knowing.
🔤 Etymology: Where Did Kryptonite Come From?
-
Root: Krypton — the fictional planet where Superman was born
-
Suffix: -ite — a common ending for minerals (like graphite or granite)
-
Origin: First appeared in the Superman radio serial in 1943, later introduced in comics in 1949 (Superman #61)
The word was invented to create tension in Superman’s invincible story. By giving him a specific weakness, writers gave readers something more relatable: vulnerability.
