## About "mammal" in BIP39

- "mammal" has 6 letters, but the first three, **"mam"**, already identify it, because **"ma"** also begins 32 other words, among them [machine](/bip39-word/machine/), [mad](/bip39-word/mad/), [magic](/bip39-word/magic/) and [magnet](/bip39-word/magnet/). Three letters are enough for only 604 of the 2048 words.
- **"mamm"** is unique only within the English list: it also begins mammouth in the [French list](/french/), so a four-letter backup should say which list it uses.
