Why Classify Constitutions? Classification is comparison disciplined: sorting constitutions into types reveals the design choices each made and what those choices cost. A constitution's classification predicts how it changes, how power is shared, and how the head of state relates to the government. Two cautions before the five pairs: (i) the pairs are ideal types — real constitutions sit on spectra (Britain has written statutes inside an "unwritten" constitution; India is federal with strong unitary features); (ii) classification is by dominant character, not by the label on the tin. Every pair below is answered in the four-move exam format: definition → exemplars → merits/demerits → Nepal's position.
