Reparation refers to different ideas:

• Compensation
  • War reparations: Payments from one country to another, possibly as compensation for starting a war under a peace treaty (for example those made by Germany to the Allies under the Treaty of Versailles), but can also more controversially include payments demanded in exchange for peace or lack of invasion (regardless of the source of initial aggression).
  • Compensation for oppression
    • Holocaust reparations for victims of persecution under the Nazi regime.
    • Compensation of Japanese Americans for internment during World War II.
    • Reparations for slavery of groups or individuals.
• Reparation is also an alternate English-language title for the Leo Tolstoy play, The Living Corpse.
• Tissue reparation means, that the necrotic tissue or tissue, removed in injury, is replaced not with new parenchymatous tissue of the same kind, but with a fibrous scar. If it is replaced with the new tissue, the process is called regeneration.
