## About "discover" in BIP39

- "discover" has 8 letters, but the first four, **"disc"**, already identify it, because **"dis"** also begins 7 other words, among them [disagree](/bip39-word/disagree/), [disease](/bip39-word/disease/), [dish](/bip39-word/dish/) and [dismiss](/bip39-word/dismiss/).
- **"disc"** is unique only within the English list: it also begins discuter in the [French list](/french/), disco in the [Spanish list](/spanish/), discreto in the [Italian list](/italian/) and discreta in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
- "discover" appears in one of the 24 official English [test vectors](https://github.com/trezor/python-mnemonic/blob/master/vectors.json) of BIP39: vector #18 (word 10 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.
