Redress is mainly used as a verb that means to remedy or set right. But it can also be used as a noun that refers to a remedy or compensation.
Sharing its Middle English origin with the word ‘address,’ redress simply adds the Latin prefix R-E. So when we redress something, as opposed to addressing it, we ‘address’ something that was missed the first time.
When my paycheck was short a few weeks, I contacted the supervisor to redress the situation. To remedy things, they paid me for a few extra weeks on my next check.
