Why do I only need the first 4 letters for each word in a mnemonic seed phrase?

BIP39 words are pulled from a specific list of 2048 words. In this list, the first 4 letters are unique to each word. (including the words that only have 3 letters)

There are no two words in this list with the same first 4 letters.

That means if you have the first 4 letters, you know the rest of the word by looking for those first 4 letters in the BIP39 list.

Please use this guide to look up the full word of your mnemonic if you are using the 4 letters system on ELLIPAL Metal Mnemonic.
