An important aspect of an unwritten constitution is that it

Step 1: Analyze the question The question asks for an important feature of an unwritten constitution, one not compiled into a single formal document.

Step 2: Explain the concept An unwritten constitution is not codified in one document. It is made up of:

• Customs and traditions
• Conventions (accepted practices that are not legally binding but are followed)
• Judicial decisions (common law)
• Statutes and historic documents scattered over time (e.g., the Magna Carta in Britain)

The United Kingdom is the standard example. Unwritten constitutions are also generally flexible, meaning they are easy to amend, because Parliament can change them through ordinary legislation or by evolving practice.

Step 3: Evaluate each option

• A. Easy to understand to everybody: Wrong. Since the rules are scattered across customs, conventions and several documents, it is actually harder for the average person to understand.
• B. Safeguards the monarchy: Wrong. This is not a defining feature. Some unwritten constitutions have monarchies, but protecting one is not what makes a constitution unwritten.
• C. Contains customary laws and conventions: Correct. Customs and conventions are the core content of an unwritten constitution.
• D. Is not easily amended: Wrong. This describes a rigid constitution, which is usually a written one. Unwritten constitutions are flexible.

Step 4: Answer

Exam tip: Link the words together:

• Unwritten → customs and conventions → flexible
• Written → codified document → rigid (hard to amend)

If an option mentions "not easily amended," think of a written, rigid constitution, so it is a trap here.
