It's a plan for running a country.
A constitution is far more than a plan; it's the framework of laws for a country or state.
Both of the above answers are correct, but somewhat vague. A constitution generally outlines the powers and responsibilities of a government, be it national or regional (as in a province or state). It tells what and, broadly, how a government will regulate life within it's confines and in relation to other governments.
... within its confines ...
Yes, the relationship between the national government and local governments within, but also foreign affairs as in the making of treaties, etc. Our US constitution defines who makes treaties with foreign governments. But keep in mind that other nations may or may not address things the same way we do. The United Kingdom, for example, has no written constitution at all. Russia has one, but is still pretty much a dictatorship by default if not de jure. Everybody's different.
A constitution is defind as a body of laws or regulation that covers and abide a specific group, nation or state.
thank you
