## About "sunny" in BIP39

- "sunny" has 5 letters, but the first four, **"sunn"**, already identify it, because **"sun"** also begins [sun](/bip39-word/sun/) and [sunset](/bip39-word/sunset/).
- Its first letters also spell another BIP39 word, [sun](/bip39-word/sun/). Write "sunny" out in full: cut short, it turns into a different valid word.
