Redress means to set something right or fix an injustice. When you redress a wrong, you're correcting it or making up for harm that was done.

If a store accidentally overcharges you and then gives you your money back, they're providing redress. When a referee makes a bad call in a game and then reverses the decision, that's a form of redress. A teacher might redress an unfair grade by reviewing the work again and correcting the score.

The word often appears in formal contexts about fixing injustices or balancing unfair situations. People might seek redress through the courts when they've been wronged, asking a judge to make things fair again. A government might offer redress to citizens who were harmed by an unjust law.

You can use redress as a noun too: “The students demanded redress for the unfair policy.” The key idea is making something wrong into something right by restoring balance and fairness where it had been lost.
