Definition

Injury is damage caused by transitory interaction with an agent such as an insect, chemical, or unfavorable environmental condition.

Etymology. 1382, from Anglo-Fr. injurie "wrongful action," from L. injuria "wrong, hurt," noun use of fem. of injurius "wrongful, unjust," from in- "not" + jus (gen. juris) "right, law" (see jurist). Injure (v.) is a back-formation first recorded 1583; the earlier verb was injury (c.1484).
