## About "thank" in BIP39

- "thank" has 5 letters, but the first four, **"than"**, already identify it, because **"tha"** also begins [that](/bip39-word/that/).
- "thank" appears in four of the 24 official English [test vectors](https://github.com/trezor/python-mnemonic/blob/master/vectors.json) of BIP39: vectors #2 (words 3 and 11 of 12), #6 (words 3 and 11 of 18), #10 (words 3, 11 and 19 of 24) and #13 (word 8 of 12). 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.
