The Origin of Injust vs Unjust
The word unjust comes from Latin. It comes from “injustus,” which means not just or unfair. Over time, English kept the spelling unjust instead of injust.
In early Latin, the prefix “in-” meant “not.” But when English adopted many Latin words, spelling changes happened. In some words, “in-” stayed. In others, it changed or blended with sound patterns.
That is why we have:
- unjust (correct form)
- injustice (noun form)
- unjustified (related adjective)
But we do not have injust as a proper word.
People sometimes create injust by removing letters from injustice. Others think it follows patterns like incorrect or incomplete. But English spelling does not always follow strict logic. That is why injust never became standard.
If you are wondering what is the meaning of injust, the answer is simple: it has no official meaning in modern English.
