Harmonize → It is formed from "harmonia" (from Greek ἁρμονία, meaning agreement or concord) and the suffix "-ize" (meaning to make or to cause to be). The word "harmonize" means to make things agree or to bring them into harmony.
Think of creating agreement or concord ('harmonia') and making it happen ('-ize') — that's how harmonize means to bring things into harmony.
