There are ways the constitutions meaning can change over time; those include formally amending the constitution, The Supreme Court ruling on a case, ad the us congress passing laws that clarify parts of the constitution- tell me how an amendment is created and ratified and give me an example of each of the 3 ways the constitution meaning has changed over time

An amendment to the Constitution can be proposed in two ways:

1. Two-thirds of both houses of Congress can vote to propose an amendment.
2. Two-thirds of the state legislatures can call for a national convention to propose amendments.

Once an amendment is proposed, it must be ratified by either:
1. Three-fourths of the state legislatures.
2. Ratification conventions in three-fourths of the states.

An example of each of the three ways the Constitution's meaning has changed over time are:

1. Formal Amendment: The 13th Amendment abolished slavery in the United States in 1865. This amendment was proposed by Congress and ratified by the states.

2. Supreme Court Ruling: In the case of Brown v. Board of Education in 1954, the Supreme Court ruled that racial segregation in public schools was unconstitutional, overturning the precedent set by Plessy v. Ferguson.

3. Congressional Legislation: The Civil Rights Act of 1964 was passed by Congress to enforce the 14th Amendment's Equal Protection Clause and prohibit discrimination based on race, color, religion, sex, or national origin.
