## About "pass" in BIP39

- "pass" has 4 letters, but the first three, **"pas"**, already identify it, because **"pa"** also begins 24 other words, among them [pact](/bip39-word/pact/), [paddle](/bip39-word/paddle/), [page](/bip39-word/page/) and [pair](/bip39-word/pair/). Three letters are enough for only 604 of the 2048 words.
- **"pass"** is unique only within the English list: it also begins passion in the [French list](/french/), passivo in the [Italian list](/italian/) and passado in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
