## About "adapt" in BIP39

- "adapt" has 5 letters, but the first three, **"ada"**, already identify it, because **"ad"** also begins 8 other words, among them [add](/bip39-word/add/), [addict](/bip39-word/addict/), [address](/bip39-word/address/) and [adjust](/bip39-word/adjust/). Three letters are enough for only 604 of the 2048 words.
- **"adap"** is unique only within the English list: it also begins adaptar in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
