## About "quantum" in BIP39

- "quantum" has 7 letters, but the first four, **"quan"**, already identify it, because **"qua"** also begins [quality](/bip39-word/quality/) and [quarter](/bip39-word/quarter/).
- **"quan"** is unique only within the English list: it also begins quantia in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
