The word "immoral" is best recognized by looking at its parts: "im" + "moral." The "im-" is a prefix meaning not. Generally, this prefix is of the form "i-," though it often adds the consonant that starts the base word—as in "immoral." The word "moral" means either dealing with ethical matters or good, as in someone who is actually ethical.
