About "certain" in BIP39
- "certain" has 7 letters, but the first four, "cert", already identify it, because "cer" also begins cereal.
- "cert" is unique only within the English list: it also begins certeza in the Spanish list, certo in the Italian list and certeiro in the Portuguese list, so a four-letter backup should say which list it uses.
