brutal
Extremely harsh, cruel, or very hard to endure.
Brutal means extremely harsh, cruel, or violent. When a winter storm is brutal, it brings freezing temperatures, fierce winds, and dangerous conditions that test everyone's endurance. When a teacher gives brutally honest feedback, they tell the complete truth without softening it, even if it stings a little.
A brutal attack shows no mercy. A brutal training schedule pushes athletes to their absolute limits. A brutal defeat in sports means losing by a huge margin, like 42 to 3.
Sometimes people use brutal more casually to describe anything extremely difficult or unpleasant. You might hear someone say a math test was brutal when it had impossibly hard problems, or that cleaning out a messy garage was brutal work. The word carries weight: it suggests something that pushes the boundaries of what seems fair or reasonable.
Unlike words like “difficult” or “challenging,” brutal implies a kind of punishing harshness. There's no gentleness in brutality. When historians describe brutal conditions prisoners faced in ancient prisons, or when people talk about the brutal heat of the desert, they're emphasizing something that shows no kindness or restraint.
