Not fair or just; morally wrong or wicked.
The unrighteous actions of the leader led to widespread discontent among the people.
Unrighteous → It is formed from "un-" (meaning not) and "righteous" (from Old English "rihtwis", meaning just or right). The word "unrighteous" means not just or not right, indicating a lack of moral integrity.
Think of 'not' ('un-') being added to 'just' or 'right' ('righteous') — that's why unrighteous means not just or morally wrong.
