Root Explanation

Radiational → It is formed from "radiate" (from Latin "radiatus", meaning to emit rays) and "-ional" (a suffix used to form adjectives indicating a relationship). The word "radiational" refers to something that relates to or involves the emission of rays or radiation.

Memory Tip

Think of 'radiate' as emitting rays, and the '-ional' suffix indicates a relationship, so 'radiational' means relating to the emission of rays.
