## About "cement" in BIP39

- "cement" has 6 letters, but the first three, **"cem"**, already identify it, because **"ce"** also begins [ceiling](/bip39-word/ceiling/), [celery](/bip39-word/celery/), [census](/bip39-word/census/), [century](/bip39-word/century/), [cereal](/bip39-word/cereal/) and [certain](/bip39-word/certain/). Three letters are enough for only 604 of the 2048 words.
- **"ceme"** is unique only within the English list: it also begins cemento in the [Spanish list](/spanish/), so a four-letter backup should say which list it uses.
