## About "surprise" in BIP39

- "surprise" has 8 letters, but the first four, **"surp"**, already identify it, because **"sur"** also begins [sure](/bip39-word/sure/), [surface](/bip39-word/surface/), [surge](/bip39-word/surge/), [surround](/bip39-word/surround/) and [survey](/bip39-word/survey/).
- The same spelling is in the [French BIP39 wordlist](/french/), but as word #1834 (index 1833), not #1748\. A wallet set to French reads "surprise" as **11100101001** instead of **11011010011**, and decodes index 1747 as "sensible".
- **"surp"** is unique only within the English list: it also begins surpresa in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
