About "avocado" in BIP39
"avocado" is the #128 word
in the official BIP39 English mnemonic wordlist. It is encoded as the 11-bit binary value
00001111111
(decimal index 127), placing it at the 6% mark of the full 2048-word list.
The 4-letter prefix "avoc" uniquely identifies this word among all 2048 entries. With 7 characters, "avocado" is among the longer entries in the list, which reduces the chance of confusion with other words during manual seed phrase entry.
Positioned in the first quarter of the wordlist (index 127), "avocado" starts with "A" — a letter group containing 136 words total. It is word #128 within that group. Words early in the list have lower binary values with more leading zeros, which can be relevant when analyzing raw entropy data.
In a 12-word seed phrase, each word encodes 11 bits of entropy. The probability of "avocado" appearing in any specific position of a randomly generated phrase is 1 in 2048 (≈ 0.049%). A complete 24-word phrase encodes 256 bits of entropy, providing security equivalent to a key space of approximately 1.16 × 10⁷⁷ — far beyond the reach of brute-force attacks.
