## About "curtain" in BIP39

- "curtain" has 7 letters, but the first four, **"curt"**, already identify it, because **"cur"** also begins [curious](/bip39-word/curious/), [current](/bip39-word/current/) and [curve](/bip39-word/curve/).
- **"curt"** is unique only within the English list: it also begins curto in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
- "curtain" appears in one of the 24 official English [test vectors](https://github.com/trezor/python-mnemonic/blob/master/vectors.json) of BIP39: vector #13 (word 5 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.
