## About "double" in BIP39

- "double" has 6 letters, but the first three, **"dou"**, already identify it, because **"do"** also begins 12 other words, among them [doctor](/bip39-word/doctor/), [document](/bip39-word/document/), [dog](/bip39-word/dog/) and [doll](/bip39-word/doll/). Three letters are enough for only 604 of the 2048 words.
- The same spelling is in the [French BIP39 wordlist](/french/), but as word #595 (index 594), not #526\. A wallet set to French reads "double" as **01001010010** instead of **01000001101**, and decodes index 525 as "délice".
