A wound or injury was any of many types of damage which could be done to a lifeform. It could be done deliberately or accidentally, to harm or heal. Those injured during a battle were said to be "wounded in action".
In 2364, Captain Jean-Luc Picard asked Counselor Deanna Troi's opinion on whether the Ligonians would injure the kidnapped Tasha Yar. Troi didn't believe so as the Ligonians seemed mainly curious, however, she did sense some sexual attraction from all the males. (TNG: "Code of Honor")
