(decimal index 1818), placing it at the 89% mark of the full 2048-word list.
The 4-letter prefix "toda" uniquely identifies this word among all 2048 entries. At 5 characters, it falls in the typical length range for BIP39 words, balancing readability with distinctiveness during manual wallet recovery.
