What is meant by the word ‘sovereign’ in the preamble of the Indian Constitution?
‘Sovereignty’ means the independent authority of a State. It has two aspects, internal and external.
From the internal standpoint it means that it has the power to legislate on any subject, to promote the health, morals, education and good order of the people, subject only to the federal division of legislative powers and other limitations imposed by the Constitution, e.g., the fundamental rights.
The external sovereignty of India means that it is not subject to the control of any other State or external power; secondly, that it can acquire foreign territory and also cede any part of the Indian territory, subject to limitations( if any ) imposed by the Constitution.
