## About "across" in BIP39

- "across" has 6 letters, but the first three, **"acr"**, already identify it, because **"ac"** also begins 13 other words, among them [access](/bip39-word/access/), [accident](/bip39-word/accident/), [account](/bip39-word/account/) and [accuse](/bip39-word/accuse/). Three letters are enough for only 604 of the 2048 words.
- **"acro"** is unique only within the English list: it also begins acronyme in the [French list](/french/) and acrobata in the [Italian list](/italian/), so a four-letter backup should say which list it uses.
