The abstractional concepts in the theory were difficult for many to grasp.
Abstractional → It is formed from "abstract" (from Latin "abstractus", meaning drawn away or separated) and "-ional" (a suffix used to form adjectives meaning relating to). The word "abstractional" refers to something that relates to the act of drawing away or separating ideas from specific instances.
Think of the idea of 'drawing away' ('abstract') from specific details, and the '-ional' suffix indicates it relates to that process.
