Sportscast → It is formed from "sport" (from Old French *desport*, meaning leisure or activity) and "cast" (from Old English *castan*, meaning to throw or broadcast). The word "sportscast" refers to the act of broadcasting or throwing out information about sports events.
Think of 'sport' as an activity and 'cast' as throwing out information — that's why a sportscast is about throwing out news on sports.
