## About "inside" in BIP39

- "inside" has 6 letters, but the first four, **"insi"**, already identify it, because **"ins"** also begins [insane](/bip39-word/insane/), [insect](/bip39-word/insect/), [inspire](/bip39-word/inspire/) and [install](/bip39-word/install/).
- **"insi"** is unique only within the English list: it also begins insigne in the [French list](/french/), insieme in the [Italian list](/italian/) and insistir in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
- "inside" appears in one of the 24 official English [test vectors](https://github.com/trezor/python-mnemonic/blob/master/vectors.json) of BIP39: vector #18 (word 24 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. As the last word of vector #18, its final 8 bits, **10101001**, are the checksum of the 24-word phrase.
