## About "eyebrow" in BIP39

- "eyebrow" has 7 letters, but the first four, **"eyeb"**, already identify it, because **"eye"** also begins [eye](/bip39-word/eye/).
- Its first letters also spell another BIP39 word, [eye](/bip39-word/eye/). Write "eyebrow" out in full: cut short, it turns into a different valid word.
- "eyebrow" appears in one of the 24 official English [test vectors](https://github.com/trezor/python-mnemonic/blob/master/vectors.json) of BIP39: vector #18 (word 2 of 24). 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.
