## About "diagram" in BIP39

- "diagram" has 7 letters, but the first four, **"diag"**, already identify it, because **"dia"** also begins [dial](/bip39-word/dial/), [diamond](/bip39-word/diamond/) and [diary](/bip39-word/diary/).
- **"diag"** is unique only within the English list: it also begins diagrama in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
- "diagram" appears in one of the 24 official English [test vectors](https://github.com/trezor/python-mnemonic/blob/master/vectors.json) of BIP39: vector #15 (word 2 of 24). Every official vector passes the [checksum checker](/bip39-checksum-checker/), and [How BIP39 works](/how-bip39-works/) shows how the entropy turns into such words.
