Present participle of prey; hunting and killing for food, or taking advantage of someone's weakness.
From Old French preie meaning 'prey,' from Latin praeda 'booty, plunder.' The verb form developed in Middle English, extending from literal hunting to metaphorical exploitation of vulnerable people.
The dual meaning of 'preying' - both natural predation and human exploitation - shows how we use animal behavior to understand social dynamics. The word carries moral weight when applied to humans, suggesting that taking advantage of weakness violates our social contract unlike natural predation.
