Fictionally → It is formed from "fiction" (from Latin "fictio", meaning the act of making or shaping) and the suffix "-ally" (meaning in a manner of). The word "fictionally" means in a manner that relates to or is characteristic of fiction.
Think of 'fiction' as the act of 'making up' stories, and '-ally' means in a way. So, when something is described as fictional, it relates to the way stories are made up.
