## About "upgrade" in BIP39

- "upgrade" has 7 letters, but the first three, **"upg"**, already identify it, because **"up"** also begins [update](/bip39-word/update/), [uphold](/bip39-word/uphold/), [upon](/bip39-word/upon/), [upper](/bip39-word/upper/) and [upset](/bip39-word/upset/). Three letters are enough for only 604 of the 2048 words.
- "upgrade" appears in one of the 24 official English [test vectors](https://github.com/trezor/python-mnemonic/blob/master/vectors.json) of BIP39: vector #20 (word 9 of 18).
