## About "pact" in BIP39

- "pact" has 4 letters, but the first three, **"pac"**, already identify it, because **"pa"** also begins 24 other words, among them [paddle](/bip39-word/paddle/), [page](/bip39-word/page/), [pair](/bip39-word/pair/) and [palace](/bip39-word/palace/). Three letters are enough for only 604 of the 2048 words.
- **"pact"** is unique only within the English list: it also begins pacto in the [Spanish list](/spanish/) and pactuar in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
- "pact" appears in one of the 24 official English [test vectors](https://github.com/trezor/python-mnemonic/blob/master/vectors.json) of BIP39: vector #16 (word 10 of 12). Every official vector passes the [checksum checker](/bip39-checksum-checker/), and [How BIP39 works](/how-bip39-works/) shows how the entropy turns into such words.
