Get down with the lingo.
PreambleThe Preamble ("preamble" is basically a fancy term for "introduction") to the United States Constitution is only one sentence long, but it's one of the most famous and important sentences in American history. "We the People," it begins, establishing the principle of popular sovereignty before then going on to explain the purposes of the Constitution: "to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity."
An introduction or preface (The most famous is of the Constitution)
Not the moment before you casually stroll over to talk to the cute girl, but the introduction of a document, stating its purpose, aims, philosophy, and justification
A preamble is basically just an introduction. It might tell you what's coming up and why the author decided to write it. The U.S. Constitution has one. It's kind of famous, maybe you've heard of it?
ArticleThe Constitution is divided into seven sections, each one called an "Article." The first three articles describe the structures and powers of the three branches of government— legislative, executive, and judicial. Article IV establishes ground rules for interactions among the states, as well as between the states and the federal government. Article V creates a process for amending the Constitution; Article VI is a bit of a hodgepodge of important principles that don't obviously fit in anywhere else; and Article VII lays out the procedure for the Constitution's ratification.
A clause or section of a legal document that specifies a rule or regulation.
AmendmentAmendments are formal changes to the Constitution. Article V creates a process that makes it difficult but not impossible to amend the Constitution; an amendment can only take effect if it first passes Congress by a two-thirds supermajority (or is passed by the legislatures of two-thirds of all the states), then is subsequently ratified by three-fourths of the states. In the 230+ years since the Constitution took effect, thousands of amendments have been proposed but only 27 have been ratified. The first ten amendments, all passed by the very first Congress, are known as the Bill of Rights.
A change to the Constitution or to a specific law. Congress routinely amends ordinary laws by majority vote; amending the Constitution is considered to be a much more serious matter and requires approval by a two-thirds vote of Congress, followed by ratification from three-fourths of the states.

FederalismFederalism is the system of government which divides power between one centralized national government and many decentralized state governments. The Constitution explicitly protects the principle of federalism, granting the national government many specific powers and responsibilities but also reserving many other powers to the various state and local governments, or to the people as individuals.
A system of government where powers and responsibilities are shared among national, state, and local governments.
The division of power between the state governments and the federal (centralized) government. It's another form of checks and balances that counteracts the federal government with local control (and vice versa), so neither can be almighty. The tricky wording in the Constitution, though, has fueled the debate over states' rights and the power of federal government in today's politics.
Checks And BalancesThe system of checks and balances is designed to prevent any one branch of the government from gaining tyrannical power. The Constitution divides the government into three branches, each of which is expected to keep the others in check. Congress's power of impeachment, for example, allows it to check and balance the power of the executive branch. The president's veto, meanwhile, allows the executive to check and balance the legislative.
The principle outlined in the Constitution that the branches of government will counterbalance each other, so that no single branch gets too powerful.
This is strongly related to the separation of powers—each branch of government has built-in limits to its power (checks) and ways to limit the power of other branches (balances). For instance, Congress can introduce laws, but the President has the final say over whether to approve or veto it. If the President does veto a law, Congress still has a chance to override the veto with a two-thirds majority. It's just one of the many ways that the Constitution prevents one person or branch from ruling over everything.
Limited GovernmentThe principle of limited government holds that the government is not all-powerful, but instead has the right to exercise its authority only in certain limited areas. The Constitution grants the US government the power, for example, to levy taxes and to declare war… but it explicitly restricts the government's power to establish a national religion or imprison people without trial.
A governmental system that promotes minimal governmental involvement in the economy or personal liberties. In other words, the power of the government is, well, limited.
Rule Of LawThe principle of the rule of law simply means that the law applies equally to everyone, and that no one is above the law. All officials of the US government (including the President, justices of the Supreme Court, and members of Congress) must take an oath pledging to uphold the Constitution—that is, to respect the rule of law.
Separation Of PowersThe separation of powers seeks to prevent tyrannical abuses of authority by dividing the most important powers of the state among different branches of government. The Framers of the US Constitution, following models first developed in Ancient Greece and the Roman Republic, gave the legislative branch the sole power to make the law, the executive branch the sole power to implement the law, and the judicial the sole power to judge the law.
Also known as "checks and balances," the political doctrine that divides power amongst the three branches of government. The legislative branch makes laws; the executive branch carries out laws; the judicial branch decides the outcome of disputes under the law.
The idea that political authority should be divided into different branches of government, instead of concentrating power in one branch. In the U.S., that means the Executive, Legislative, and Judicial branches all have different, but equally significant, powers. The President can't randomly decide to make every Monday free ice-cream day (sadly)—he or she has to get Congress and the Supreme Court's approval.
Popular SovereigntyThe doctrine of popular sovereignty holds that the legitimacy and authority of government derives only from the consent of the people, who are the ultimate source of political power. The Constitution of the United States (which famously begins with the words, "We the People") is built upon the principle of popular sovereignty.
The idea that the state is created and sustained by and for the people. The people are the sovereigns of the government.
Enacted by the Kansas-Nebraska Act, this principle held that each state could decide on its own whether to allow slavery. This was popular among Southerners, not so much among Northerners.
The idea that authority resides with the people, not the king. It's why the Constitution starts with "we the people" and not "King George III says…"
Judicial ReviewThe right of the Supreme Court to review and take action against any legislation—local, state, or federal—it deems to be unconstitutional.
Judicial review is the idea that the judicial branch of government (in the United States, the Supreme Court) has the right and responsibility to invalidate actions by the other branches of government if they are judged to be unconstitutional. If Congress passes a law or the President undertakes an executive action that a majority of the Supreme Court believes to run afoul of the Constitution, the Court can overturn that law or executive action. Judicial review is a critical part of the American system of checks and balances, giving the judicial branch its most powerful tool to limit the executive andlegislative branches. Interestingly, the power of judicial review is not explicitly named in the Constitution; the Supreme Court itself declared that it had the power of judicial review for the first time in the 1803 case of Marbury v. Madison.
The authority of the courts to rule on the constitutionality of legislative actions. This power was not expressly granted in the Constitution and thus was not universally acknowledged with the ratification of the Constitution in 1789. Alexander Hamilton argued in Federalist #78 that it was implied by Article III of the Constitution. But others argued that this claim placed the judiciary above the legislative branch and contradicted the democratic premises of America's political system. In Marbury v. Madison (1803) the Supreme Court asserted this power for the first time; Chief Justice John Marshall's Court would assert the same power in fifteen additional cases. Some continued to challenge the court's authority to do so, but the principle of judicial review was widely established by Marshall's death in 1835.
The power of federal judges to strike down Congressional laws that violate the Constitution
This is the power exercised by the Supreme Court to determine the constitutionality of laws. This right was not specifically provided by the Constitution but was exercised in the famous case of Marbury v. Madison and has been the precedent followed since.
When the Supreme Court decides whether a legislative or executive action is constitutional, it's practicing judicial review. It's the most important check the judicial branch has over the other branches.
UnconstitutionalThe Constitution of the United States is, in its own words, the "supreme Law of the Land." That means that no other law can counteract or override the Constitution itself. If Congress passes a law (or the President undertakes an executive action) that runs afoul of the Constitution, the Supreme Court can use its power of judicial review to rule that such a law (or executive action) is unconstitutional and therefore should be overturned.
A legislative act or executive action which violates the terms of the constitution is said to be unconstitutional. The Supreme Court has the authority to overturn laws or executive orders that it finds to be unconstitutional.
Bill Of RightsThe Bill of Rights is the name given to the first ten amendments to the United States Constitution, passed by the first US Congress and ratified in 1791. The Bill of Rights includes explicit guarantees of many of the most important rights and liberties held by American citizens: freedom of speech, freedom of religion, freedom of assembly, freedom of the press, the right to bear arms, freedom from unreasonable search and seizure, etc.
Americans call the first ten amendments to our Constitution the Bill of Rights. And no, it does not include your right to get a tattoo without asking your parents' permission. (Maybe you should propose that.)
Added to the Constitution as the first ten amendments, our Bill of Rights outlines the many personal freedoms we are guaranteed as citizens of the United States.
The first ten amendments to the Constitution, which were proposed all at once in 1789 before many states had even ratified the Constitution. Don't think of the Bill of Rights as an afterthought, though—it protects our freedom of speech, religion, the press, and our right to bear arms, among other important things.
