Root Explanation
Directional → It is formed from "direct" (from Latin "directus", meaning straight or guided) and "-ional" (a suffix used to form adjectives indicating a relationship). The word "directional" refers to something that relates to or indicates direction.
Memory Tip
Think of something that is 'guided' ('direct') and relates to a specific 'relationship' ('-ional') — that's why directional means relating to direction.
