## About "strong" in BIP39

- "strong" has 6 letters, but the first four, **"stro"**, already identify it, because **"str"** also begins [strategy](/bip39-word/strategy/), [street](/bip39-word/street/), [strike](/bip39-word/strike/) and [struggle](/bip39-word/struggle/).
- **"stro"** is unique only within the English list: it also begins strozzare in the [Italian list](/italian/) and strom in the [Czech list](/czech/), so a four-letter backup should say which list it uses.
