## About "lava" in BIP39

- "lava" has 4 letters, but the first three, **"lav"**, already identify it, because **"la"** also begins 19 other words, among them [lab](/bip39-word/lab/), [label](/bip39-word/label/), [labor](/bip39-word/labor/) and [ladder](/bip39-word/ladder/). Three letters are enough for only 604 of the 2048 words.
- **"lava"** is unique only within the English list: it also begins lavabo in the [French list](/french/), lavar in the [Spanish list](/spanish/), lavagna in the [Italian list](/italian/) and lavanda in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
- "lava" 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 12 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.
