What does the term "nullify" mean?

The term "nullify" means to make something invalid or worthless. This can refer to legal decisions, agreements, or any situation where the validity or effectiveness of something is completely erased or declared null. For example, a law can be nullified if it is ruled unconstitutional, meaning it has no legal power or effect. The essence of nullification involves a negation or cancellation, making it synonymous with rendering something void or ineffective. Understanding this term is crucial in contexts such as legal studies, politics, and even in everyday situations where something might be rendered ineffectual or meaningless.
