About "umbrella" in BIP39
- Two letters are enough: no other BIP39 word begins with "um", which makes "umbrella" one of only 34 words that can be told apart this early.
- "umbr" is unique only within the English list: it also begins umbral in the Spanish list, so a four-letter backup should say which list it uses.
