Constitutional law lies at the heart of a nation's legal and political framework. It governs the fundamental principles by which a state is organized, powers are distributed, and rights are protected. As such, the vocabulary of Constitutional Law Terms is complex, nuanced, and often rooted in centuries of jurisprudential development. This dictionary is designed to serve as a practical, authoritative resource for students, legal professionals, academics, and anyone seeking clarity on the terminology and concepts that define constitutional governance.The aim of this methodological manual is to offer clear, concise, and accurate definitions of key constitutional law terms. Where appropriate, entries are supplemented with references to landmark cases, doctrinal developments, or comparative insights from other constitutional systems. This approach helps readers grasp not only the literal meaning of a term but also its functional role within legal discourse and institutional practice.
