unfairness
Word family
Synonym discussion
Sense: noun/1
All four words describe situations where people are not treated fairly, but they highlight different angles. 'Unfairness' is the broadest everyday term — it covers any situation that feels morally wrong or unequal, from a teacher favouring certain students to an unequal pay system. 'Injustice' is more formal and often implies a violation of a legal or moral right, making it the preferred word in legal and political contexts. 'Inequality' focuses on measurable differences in resources, opportunities, or treatment rather than the moral judgment itself — you can measure income inequality without calling it unfair. 'Bias' points to the psychological or structural prejudice that causes unfairness, not the result. 'Discrimination' is the most specific: it means treating people differently based on a particular characteristic such as race, gender, or age, and it carries strong legal weight. For example: 'The students complained about the unfairness of having two different exam formats' (everyday situation), but 'The company was sued for gender discrimination' (legal violation).

Etymology
Formed in Middle English by adding the negative prefix 'un-' to 'fairness'. 'Fair' comes from Old English 'fæger' meaning 'beautiful, pleasant, just', which traces back to Proto-Germanic '*fagraz' (suitable, fitting). The sense of 'just, equitable' developed in Old English and became the dominant meaning by the 16th century.
