Definition - What does Constitution mean?
A constitution is a written foundation of a group that sets out the rules under which the group will operate, as well as the specific functions of the group.
The most recognized constitution is the U.S. Constitution, which was written to set out the national government's specific functions and the rights of the people.
In addition to countries having constitutions, corporations can also have a constitution that governs how the company will run. The main point of writing a constitution is to have guidelines that all acts fall into and that can be consulted to determine which is the best course of action for the entity in the future.
