For words that have only three letters, there is absolutely no 4th letter. Such as with the word “add”, there isn't any a lot more letters afterwards and so should be the word "increase". The word “addict” is inside the BIP39 wordlist but you would've utilised “addi” for “addict”. Retail https://growthbookmarks.com/story19550132/examine-this-report-on-bip39-passphrase
