Isonomies refer to a situation where people or groups are treated equally under the law. However, in contrast, the antonyms for isonomies suggest a lack of equality or fairness. The antonyms include discrimination, inequality, bias, injustice, and partiality. Discrimination occurs when people are treated differently based on certain attributes such as race or gender. The opposite of isonomies, inequality, describes a state of imbalance in society where some individuals or groups have more privileges, resources, and opportunities than others. Bias is another antonym, which implies a preconceived opinion that influences one's judgments, leading to unfair treatment. Injustice and partiality refer to the violation of human rights and favoritism respectively.
