## About "rapid" in BIP39

- "rapid" has 5 letters, but the first three, **"rap"**, already identify it, because **"ra"** also begins 20 other words, among them [rabbit](/bip39-word/rabbit/), [raccoon](/bip39-word/raccoon/), [race](/bip39-word/race/) and [rack](/bip39-word/rack/). Three letters are enough for only 604 of the 2048 words.
- **"rapi"** is unique only within the English list: it also begins rapide in the [French list](/french/), rapina in the [Italian list](/italian/) and rapidez in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
- "rapid" appears in one of the 24 official English [test vectors](https://github.com/trezor/python-mnemonic/blob/master/vectors.json) of BIP39: vector #23 (word 7 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.
