## About "lecture" in BIP39

- "lecture" has 7 letters, but the first three, **"lec"**, already identify it, because **"le"** also begins 17 other words, among them [leader](/bip39-word/leader/), [leaf](/bip39-word/leaf/), [learn](/bip39-word/learn/) and [leave](/bip39-word/leave/). Three letters are enough for only 604 of the 2048 words.
- The same spelling is in the [French BIP39 wordlist](/french/), but as word #1124 (index 1123), not #1017\. A wallet set to French reads "lecture" as **10001100011** instead of **01111111000**, and decodes index 1016 as "immuable".
- **"lect"** is unique only within the English list: it also begins lector in the [Spanish list](/spanish/), so a four-letter backup should say which list it uses.
