Brawnier → It is formed from "brawn" (from Old English "brægen", meaning muscle or strength) and the suffix "-ier" (meaning more). The word "brawnier" means having more muscle or strength than another.
Think of 'brawn' as representing muscle or strength, and the '-ier' indicates more of that quality. So, brawnier means having more muscle.
