About "ostrich" in BIP39
- Two letters are enough: no other BIP39 word begins with "os", which makes "ostrich" one of only 34 words that can be told apart this early.
- "ostr" is unique only within the English list: it also begins ostra in the Spanish list and ostraha in the Czech list, so a four-letter backup should say which list it uses.
- "ostrich" appears in one of the 24 official English test vectors of BIP39: vector #18 (word 12 of 24). Every official vector passes the checksum checker, and How BIP39 works shows how the entropy turns into such words.
