The Constitution begins with an introduction called the “preamble,” a word from the Latin praeambulus, meaning “walking before.” The preamble to a legal instrument identifies the parties, states crucial facts, and/or explains the purpose of the document. The “Whereas” clauses appearing in some documents are preambles.
