In the early 19th century in the United States, women could not legally vote, but they fought back against this injustice and eventually won voting rights. The word comes from a Latin phrase that literally means “not right,” and injustice is the opposite of justice, which is a fair and righteous act. Injustice can be general or specific, like the injustice suffered by poor people everywhere, or an individual act of injustice committed by some unkind person.
