## About "sadness" in BIP39

- "sadness" has 7 letters, but the first four, **"sadn"**, already identify it, because **"sad"** also begins [sad](/bip39-word/sad/) and [saddle](/bip39-word/saddle/).
- Its first letters also spell another BIP39 word, [sad](/bip39-word/sad/). Write "sadness" out in full: cut short, it turns into a different valid word.
