About "alert" in BIP39
- "alert" has 5 letters, but the first three, "ale", already identify it, because "al" also begins 14 other words, among them alarm, album, alcohol and alien. Three letters are enough for only 604 of the 2048 words.
- "aler" is unique only within the English list: it also begins alerte in the French list, alerta in the Spanish list and alertar in the Portuguese list, so a four-letter backup should say which list it uses.
