## About "gravity" in BIP39

- "gravity" has 7 letters, but the first four, **"grav"**, already identify it, because **"gra"** also begins [grab](/bip39-word/grab/), [grace](/bip39-word/grace/), [grain](/bip39-word/grain/), [grant](/bip39-word/grant/), [grape](/bip39-word/grape/) and [grass](/bip39-word/grass/).
- **"grav"** is unique only within the English list: it also begins gravir in the [French list](/french/), grave in the [Spanish list](/spanish/), gravoso in the [Italian list](/italian/) and graveto in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
- "gravity" appears in one of the 24 official English [test vectors](https://github.com/trezor/python-mnemonic/blob/master/vectors.json) of BIP39: vector #14 (word 1 of 18). 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.
