Step 1: Understanding the Concept:
The question asks for a definition of democracy that specifically incorporates the principle of Adult Franchise.

Step 2: Detailed Explanation:
Democracy based on Adult Franchise is a system of government where the supreme power is vested in the people and exercised by them through a system of representation, which is based on the principle of Universal Adult Suffrage.
This means: \begin{itemize}[noitemsep] \item Democracy: A form of government in which rulers are elected by the people. \item Adult Franchise (or Universal Adult Suffrage): The right of every adult citizen, typically above a certain age (e.g., 18 years in India), to vote in elections, irrespective of their caste, creed, religion, gender, race, or economic status. \end{itemize} In essence, it is a government "of the people, by the people, for the people," where the mechanism for the people to exercise their power is the guaranteed right of every adult to cast a vote. This ensures political equality, as it is based on the principle of 'one person, one vote, one value'.

Step 3: Final Answer:
It is a form of government where adult citizens choose their representatives through a voting system in which every adult has the right to vote, ensuring political equality.
