I think you mean the 10th Amendment (spelling). Here’s a concise explanation.

Text (exact)
"The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people."

When ratified
Part of the Bill of Rights, ratified in 1791.

Plain‑language meaning
The 10th Amendment says that any power the Constitution does not give the federal government (and does not forbid the states from having) belongs to the states or the people. It is a statement of federalism — the division of power between the national government and state governments.

What it does in practice
- Reserves to states many everyday authorities: education, local government, family law, most criminal law, property law, police powers, and regulation of health/safety within the state.
- Limits the federal government to the powers enumerated in the Constitution (and any implied powers identified by the courts).
- Does not create a general individual right; it allocates governmental power between federal and state governments.

Important legal points and Supreme Court cases
- McCulloch v. Maryland (1819): affirmed broad federal powers under the Constitution (implied powers) and limited states’ ability to interfere with valid federal action.
- New York v. United States (1992) and Printz v. United States (1997): limited Congress’s ability to “commandeer” state governments — Congress cannot force states to enact or administer federal regulatory programs.
- Garcia v. San Antonio Metropolitan Transit Authority (1985): held that the 10th Amendment does not provide a judicially enforceable limit on all federal regulation; many limits are political and structural.
- Murphy v. NCAA (2018): reaffirmed the anti‑commandeering principle by striking down a federal law that prohibited states from authorizing sports betting.
- NFIB v. Sebelius (2012): illustrates interaction with other federal powers (Commerce Clause, Taxing Power); the Court rejected using the Commerce Clause to compel individuals to buy insurance, but upheld the individual mandate as a tax.

Limits of the 10th Amendment
- It does not block federal laws that are within powers the Constitution actually grants to Congress (e.g., regulating interstate commerce, taxing, spending).
- Where the Constitution grants federal authority, the Supremacy Clause makes valid federal law supreme over state law.

Contemporary relevance
The 10th Amendment is often invoked in debates over the proper scope of federal regulation (health care, environmental rules, gun laws, marijuana legalization, etc.) and in arguments for state autonomy.

If you want, I can:
- Give brief summaries of any of the cases above, or
- List specific examples of powers typically exercised by states, or
- Explain how the 10th Amendment relates to a particular issue (e.g., marijuana laws, gun regulation, education).
