## About "atom" in BIP39

- "atom" has 4 letters, but the first three, **"ato"**, already identify it, because **"at"** also begins [athlete](/bip39-word/athlete/), [attack](/bip39-word/attack/), [attend](/bip39-word/attend/), [attitude](/bip39-word/attitude/) and [attract](/bip39-word/attract/). Three letters are enough for only 604 of the 2048 words.
- **"atom"** is unique only within the English list: it also begins atome in the [French list](/french/) and atomico in the [Italian list](/italian/), so a four-letter backup should say which list it uses.
