unfairness

This term describes a perceived lack of justice or equity, often carrying a strong emotional weight of resentment or indignation. It is frequently used in social, legal, or interpersonal contexts to highlight a discrepancy between how someone is treated and how they deserve to be treated. As an abstract noun, it is uncountable. It does not have a plural form and cannot be counted as individual units; instead, it is measured in degree or intensity, often requiring phrases like "a sense of" or "an instance of" to specify particular occurrences.
