## About "absurd" in BIP39

- "absurd" has 6 letters, but the first four, **"absu"**, already identify it, because **"abs"** also begins [absent](/bip39-word/absent/), [absorb](/bip39-word/absorb/) and [abstract](/bip39-word/abstract/).
- **"absu"** is unique only within the English list: it also begins absurde in the [French list](/french/) and absurdo in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
- "absurd" appears in three of the 24 official English [test vectors](https://github.com/trezor/python-mnemonic/blob/master/vectors.json) 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](/bip39-checksum-checker/), and [How BIP39 works](/how-bip39-works/) shows how the entropy turns into such words.
