## About "alarm" in BIP39

- "alarm" has 5 letters, but the first three, **"ala"**, already identify it, because **"al"** also begins 14 other words, among them [album](/bip39-word/album/), [alcohol](/bip39-word/alcohol/), [alert](/bip39-word/alert/) and [alien](/bip39-word/alien/). Three letters are enough for only 604 of the 2048 words.
- **"alar"** is unique only within the English list: it also begins alarmer in the [French list](/french/), alarma in the [Spanish list](/spanish/) and alarme in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
