présidentiel

Présidentiel refers to a system of government where the head of government, the president, is also the head of state. This presidential system is distinct from parliamentary systems where the head of government (often a prime minister) is separate from the head of state (often a monarch or a president with limited powers). In a presidential system, the president is typically elected independently of the legislature and holds executive power.

The president in this system usually serves a fixed term and is not accountable to the legislature in the same way a prime minister is. The legislature, often a congress or parliament, has its own distinct powers and responsibilities. This separation of powers between the executive and legislative branches is a hallmark of the presidential system. Key features include the president's ability to appoint cabinet members, veto legislation, and command the armed forces.

While the president is the chief executive, their power is usually checked by the legislature through mechanisms like impeachment, oversight, and the power to approve or reject presidential appointments and legislation. This system is designed to prevent any single branch from becoming too dominant. Examples of countries with presidential systems include the United States, Brazil, and Mexico. The specific powers and responsibilities of the president can vary significantly from one country to another within this framework.
