## About "topic" in BIP39

- "topic" has 5 letters, but the first four, **"topi"**, already identify it, because **"top"** also begins [top](/bip39-word/top/) and [topple](/bip39-word/topple/).
- Its first letters also spell another BIP39 word, [top](/bip39-word/top/). Write "topic" out in full: cut short, it turns into a different valid word.
- **"topi"** is unique only within the English list: it also begins topinka in the [Czech list](/czech/), so a four-letter backup should say which list it uses.
