Covered with sweat or producing a lot of moisture on the skin, usually from exercise, heat, or nervousness.
From sweat (Old English swat) plus -y suffix. The word has simply meant 'covered in or producing sweat' since around the 14th century, originally describing the physical state during labor or exercise.
Humans are actually weirdly good at sweating compared to other animals—our ability to cool ourselves through sweat allowed our ancestors to run long distances in the heat to hunt animals that would overheat, making us nature's marathoners.
