Etymology
Origin of pain
First recorded in 1250–1300; Middle English peine “punishment, torture, pain,” from Old French, from Latin poena “penalty, pain,” from Greek poinḗ “penalty”
Explanation
If you feel pain, you feel acute physical or emotional discomfort. A sprained ankle will pain you. So will news of a loved one's death. If you "take pain" over something, it means you're being careful. An annoying person can be described as a pain––it's understood that they don't cause you actual physical pain, but cause you emotional discomfort and distress. You can also describe this person as a "pain in the neck," "a pain in the butt," or "a royal pain."
