Beefiest → It is formed from "beef" (from Old French *beuf*, meaning the flesh of a cow) and "-iest" (a superlative suffix indicating the most). The word "beefiest" means having the most beef or being the most substantial in terms of beefiness.
Think of 'beef' as the meat from a cow, and when you add '-iest', it means the most of that meat. So, 'beefiest' refers to something that has the most beef.
