Write "card" out in full: cut short, it turns into a different valid word. - **"card"** is unique only within the English list: it also begins cardo in the [Italian list](/italian/) and cardeal in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses. - "card" 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 4 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.
