Explanation: The American Constitution was the first to begin with a Preamble. Many countries, including India, followed this practice. The term ‘Preamble’ refers to the introduction or preface to the Constitution.

It contains the summary or essence of the Constitution. N.A. Palkhivala, an eminent jurist and constitutional expert, called the Preamble as the ‘identity card of the Constitution.’
