## About "question" in BIP39

- "question" has 8 letters, but the first three, **"que"**, already identify it, because **"qu"** also begins 7 other words, among them [quality](/bip39-word/quality/), [quantum](/bip39-word/quantum/), [quarter](/bip39-word/quarter/) and [quick](/bip39-word/quick/). Three letters are enough for only 604 of the 2048 words.
- The same spelling is in the [French BIP39 wordlist](/french/), but as word #1581 (index 1580), not #1405\. A wallet set to French reads "question" as **11000101100** instead of **10101111100**, and decodes index 1404 as "outrager".
- **"ques"** is unique only within the English list: it also begins queso in the [Spanish list](/spanish/), so a four-letter backup should say which list it uses.
