## About "mansion" in BIP39

- "mansion" has 7 letters, but the first four, **"mans"**, already identify it, because **"man"** also begins [man](/bip39-word/man/), [manage](/bip39-word/manage/), [mandate](/bip39-word/mandate/), [mango](/bip39-word/mango/) and [manual](/bip39-word/manual/).
- Its first letters also spell another BIP39 word, [man](/bip39-word/man/). Write "mansion" out in full: cut short, it turns into a different valid word.
- **"mans"** is unique only within the English list: it also begins manso in the [Spanish list](/spanish/), mansarda in the [Italian list](/italian/) and mansa in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
