## About "congress" in BIP39

- "congress" has 8 letters, but the first four, **"cong"**, already identify it, because **"con"** also begins 7 other words, among them [concert](/bip39-word/concert/), [conduct](/bip39-word/conduct/), [confirm](/bip39-word/confirm/) and [connect](/bip39-word/connect/).
- **"cong"** is unique only within the English list: it also begins congeler in the [French list](/french/), conga in the [Spanish list](/spanish/), congelare in the [Italian list](/italian/) and congelar in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
- "congress" appears in one of the 24 official English [test vectors](https://github.com/trezor/python-mnemonic/blob/master/vectors.json) of BIP39: vector #23 (words 9 and 17 of 18). 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.
