For words that only have 3 letters, there isn't any 4th letter. Such as with the word “include”, there are no more letters afterwards and thus need to be the word "include". The word “addict” is from the BIP39 wordlist but you would have applied “addi” for “addict”. - Lưu https://bookmarklinkz.com/story18794335/new-step-by-step-map-for-ledger-seed-phrase-bip39
