Using a non-English wordlist may result in incorrect or invalid seeds. + Each word comes from a [list of 2048 words](https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt). The words themselves are meaningless; all that matters is the word's position number (aka index) in the word list. For example, "tomato" is the 1,825th word in the list.
