## About "exist" in BIP39

- "exist" has 5 letters, but the first four, **"exis"**, already identify it, because **"exi"** also begins [exile](/bip39-word/exile/) and [exit](/bip39-word/exit/).
- **"exis"** is unique only within the English list: it also begins exister in the [French list](/french/) and existir in the [Spanish list](/spanish/), so a four-letter backup should say which list it uses.
- "exist" appears in one of the 24 official English [test vectors](https://github.com/trezor/python-mnemonic/blob/master/vectors.json) of BIP39: vector #24 (word 21 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.
