## About "mobile" in BIP39

- "mobile" has 6 letters, but the first three, **"mob"**, already identify it, because **"mo"** also begins 20 other words, among them [model](/bip39-word/model/), [modify](/bip39-word/modify/), [mom](/bip39-word/mom/) and [moment](/bip39-word/moment/). Three letters are enough for only 604 of the 2048 words.
- The same spelling is in the [French BIP39 wordlist](/french/), but as word #1260 (index 1259), not #1140\. A wallet set to French reads "mobile" as **10011101011** instead of **10001110011**, and decodes index 1139 as "ligature".
- **"mobi"** is unique only within the English list: it also begins mobil in the [Czech list](/czech/), so a four-letter backup should say which list it uses.
