About "absurd" in BIP39

  • "absurd" has 6 letters, but the first four, "absu", already identify it, because "abs" also begins absent, absorb and abstract.
  • "absu" is unique only within the English list: it also begins absurde in the French list and absurdo in the Portuguese list, so a four-letter backup should say which list it uses.
  • "absurd" appears in three of the 24 official English test vectors of BIP39: vectors #3 (word 4 of 12), #7 (words 4 and 12 of 18) and #11 (words 4, 12 and 20 of 24). Every official vector passes the checksum checker, and How BIP39 works shows how the entropy turns into such words.
