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
While the president is the chief executive, their power is usually checked by the legislature through mechanisms
