## About "sister" in BIP39

- "sister" has 6 letters, but the first three, **"sis"**, already identify it, because **"si"** also begins 18 other words, among them [sibling](/bip39-word/sibling/), [sick](/bip39-word/sick/), [side](/bip39-word/side/) and [siege](/bip39-word/siege/). Three letters are enough for only 604 of the 2048 words.
- **"sist"** is unique only within the English list: it also begins sistema in the [Spanish list](/spanish/) and sistole in the [Italian list](/italian/), so a four-letter backup should say which list it uses.
