In a seed phrase it stands for the 11-bit value `10111101001`, decimal index 1513\. /ruːl/ · _noun:_ an official instruction about what is or is not allowed [Russian](/ru/ "The BIP39 wordlist with Russian translations"): правило ## Binary Representation Seven 1-bits and four 0-bits; 330 of the 2048 indexes have exactly seven 1-bits. One wrong bit turns it into (leftmost bit first): [diamond](/bip39-word/diamond/)[wood](/bip39-word/wood/)[outdoor](/bip39-word/outdoor/)[pudding](/bip39-word/pudding/)[release](/bip39-word/release/)[rice](/bip39-word/rice/)[sand](/bip39-word/sand/)[rotate](/bip39-word/rotate/)[sad](/bip39-word/sad/)[runway](/bip39-word/runway/)[rug](/bip39-word/rug/) Position Hex Index 0x5E9 4-Letter Prefix rule ## About "rule" in BIP39 - "rule" has 4 letters, but the first three, **"rul"**, already identify it, because **"ru"** also begins [rubber](/bip39-word/rubber/), [rude](/bip39-word/rude/), [rug](/bip39-word/rug/), [run](/bip39-word/run/), [runway](/bip39-word/runway/) and [rural](/bip39-word/rural/). Three letters are enough for only 604 of the 2048 words. - **"rule"** is unique only within the English list: it also begins ruleta in the [Spanish list](/spanish/), so a four-letter backup should say which list it uses. - "rule" appears in one of the 24 official English [test vectors](https://github.com/trezor/python-mnemonic/blob/master/vectors.json) of BIP39: vector #20 (word 2 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.
