## About "indoor" in BIP39

- "indoor" has 6 letters, but the first four, **"indo"**, already identify it, because **"ind"** also begins [index](/bip39-word/index/), [indicate](/bip39-word/indicate/) and [industry](/bip39-word/industry/).
- **"indo"** is unique only within the English list: it also begins indole in the [Italian list](/italian/), so a four-letter backup should say which list it uses.
