## About "famous" in BIP39

- "famous" has 6 letters, but the first four, **"famo"**, already identify it, because **"fam"** also begins [fame](/bip39-word/fame/) and [family](/bip39-word/family/).
- **"famo"** is unique only within the English list: it also begins famoso in the [Spanish list](/spanish/), so a four-letter backup should say which list it uses.
- "famous" appears in one of the 24 official English [test vectors](https://github.com/trezor/python-mnemonic/blob/master/vectors.json) of BIP39: vector #21 (word 20 of 24). Every official vector passes the [checksum checker](/bip39-checksum-checker/), and [How BIP39 works](/how-bip39-works/) shows how the entropy turns into such words.
