Usage: The word injury is strictly a noun and should never be used as a verb; instead, use damage or harm when describing the act of causing physical or emotional hurt. Do not say "I injured him," but rather say "I harmed him" or "I caused him injury."
The word injury comes from the Latin iniūria, which originally meant "injustice," "wrong," or "offense." It entered English through Middle English and Anglo-Norman with this same sense of a violation of right or law.
