## About "pyramid" in BIP39

- Two letters are enough: no other BIP39 word begins with **"py"**, which makes "pyramid" one of only 34 words that can be told apart this early.
- **"pyra"** is unique only within the English list: it also begins pyramide in the [French list](/french/) and pyramida in the [Czech list](/czech/), so a four-letter backup should say which list it uses.
