## About "agent" in BIP39

- "agent" has 5 letters, but the first four, **"agen"**, already identify it, because **"age"** also begins [age](/bip39-word/age/).
- Its first letters also spell another BIP39 word, [age](/bip39-word/age/). Write "agent" out in full: cut short, it turns into a different valid word.
- **"agen"** is unique only within the English list: it also begins agencer in the [French list](/french/), agente in the [Italian list](/italian/) and agenciar in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
- "agent" appears in one of the 24 official English [test vectors](https://github.com/trezor/python-mnemonic/blob/master/vectors.json) of BIP39: vector #5 (word 18 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. As the last word of vector #5, its final 6 bits, **100111**, are the checksum of the 18-word phrase.
