Answer:
A Constitution is the supreme law of the country in written form accepted by the people living together in a country. It is the document containing the set of principles according to which a state or an organisation is supposed to be governed.
1) The constitution reflects the philosophy on which country's administration works and expresses aspirations of the people for creating a good society.
2) It serves as a rule book for the government.
3) It specifies the powers and limitations of the Government and clearly demarcates the areas of its functioning.
4) The constitution lays down the procedures and guidelines on how the government can be formed.
5) It states the rights and duties of citizens and directs the government to see that basic rights of the citizens are enforced.
6) It thus generates trust and coordination required for unity among the people.
7) The constitution also serves as a set of ideals that our society should live by.
