## About "siren" in BIP39

- "siren" has 5 letters, but the first three, **"sir"**, 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.
- **"sire"** is unique only within the English list: it also begins sirena in the [Spanish list](/spanish/) and sirene in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
