President (government title) in the context of "Veto"

An indirect election or hierarchical voting, is an election in which voters do not choose directly among candidates or parties for an office, but elect people who in turn choose candidates or parties. This electoral system is one of the oldest forms of elections and is used by many countries for heads of state (such as presidents), heads of government (such as prime ministers), and/or upper houses. It is also used for some supranational legislatures. The body that controls the federal executive branch (such as a cabinet) is in many countries elected indirectly by the head of government with exception of the directorial system. Upper houses, especially in federal republics, are often indirectly elected, either by the corresponding lower house or cabinet.

Positions that are indirectly elected may be chosen by a permanent body (such as a parliament) or by a special body convened solely for that purpose (such as an electoral college). An election can be partially indirect, for example in the case of indirect single transferable voting, where only eliminated candidates select other candidates to transfer their vote share to. Similarly, supranational legislatures can be indirectly elected by constituent countries' legislatures or executive governments.

A presidential, strong-president, or single-executive system (sometimes also congressional system) is a form of government in which a head of government (usually titled "president") heads an executive branch that derives its authority and legitimacy from a source that is separate from the legislative branch. The system was popularized by its inclusion in the Constitution of the United States.

This head of government is often also the head of state. In a presidential system, the head of government is directly or indirectly elected by a group of citizens and is not responsible to the legislature, and the legislature cannot dismiss the president except in extraordinary cases. A presidential system contrasts with a parliamentary system, where the head of government (usually called a prime minister) derives their power from the confidence of an elected legislature, which can dismiss the prime minister with a simple majority.

A semi-presidential republic, or dual executive republic, is a republic in which a president exists alongside a prime minister and a cabinet, with the latter of the two being responsible to the legislature of the state. It differs from a parliamentary republic in that it has an executive president independent of the legislature; and from the presidential system in that the cabinet, although named by the president, is responsible to the legislature, which may force the cabinet to resign through a motion of no confidence.

While the Weimar Republic (1919–1933) and Finland (from 1919 to 2000) exemplified early semi-presidential systems, the term "semi-presidential" was first introduced in 1959, in an article by the journalist Hubert Beuve-Méry, and popularized by a 1978 work written by the political scientist Maurice Duverger. Both men intended to describe the French Fifth Republic (established in 1958).

Secretary is a title often used in organizations to indicate a person having a certain amount of authority, power, or importance in the organization. Secretaries announce important events and communicate to the organization. The term is derived from the Latin word secernere, "to distinguish" or "to set apart", the passive participle (secretum) meaning "having been set apart", with the eventual connotation of something private or confidential, as with the English word secret. A secretarius was a person, therefore, overseeing business confidentially, usually for a powerful individual (a king, pope, etc.).

The official title of the leader of most communist and socialist political parties is the "General Secretary of the Central Committee" or "First Secretary of the Central Committee". When a communist party is in power, the general secretary is usually the country's de facto leader (though sometimes this leader also holds state-level positions to monopolize power, such as a presidency or premiership in order to constitute de jure leadership of the state), such as China, North Korea, Vietnam, Laos and Cuba.

A political campaign is an organized effort which seeks to influence the decision making progress within a specific group. In democracies, political campaigns often refer to electoral campaigns, by which representatives are chosen or referendums are decided. In modern politics, the most high-profile political campaigns are focused on general elections and candidates for head of state or head of government, often a president or prime minister.

A prime minister, also known as a chief of cabinet, chief minister, first minister, minister-president or premier, is the head of the cabinet and the leader of the ministers in the executive branch of government, often in a parliamentary or semi-presidential system. A prime minister is not the head of state, but rather the head of government, serving as the chief of the executive under either a monarch or a president in a republican form of government.

In parliamentary systems of government (be they constitutional monarchies or parliamentary republics), the Prime Minister (or occasionally a similar post with a different title, such as the Chancellor of Germany) is the most powerful politician and the functional leader of the state, by virtue of commanding the confidence of the legislature. The head of state is typically a ceremonial officer, though they may exercise reserve powers to check the Prime Minister in unusual situations.

Letters patent (plural form for singular and plural) are a type of legal instrument in the form of a published written order issued by a monarch, president or other head of state, generally granting an office, right, monopoly, title or status to a person or corporation. Letters patent can be used for the creation of corporations, government offices, to grant city status or coats of arms. Letters patent are issued for the appointment of representatives of the Crown, such as governors and governors-general of Commonwealth realms, as well as appointing a Royal Commission. In the United Kingdom, they are also issued for the creation of peers of the realm.

A particular form of letters patent has evolved into the modern intellectual property patent (referred to as a utility patent or design patent in United States patent law) granting exclusive rights in an invention or design. In this case, it is essential that the written grant should be in the form of a public (patent) document so other inventors can consult it both to avoid infringement (while the patent remains in force) and to understand how to put it into practical use (once the patent rights expire). In the Holy Roman Empire, Austrian Empire, and Austria-Hungary, imperial patent was also the highest form of generally binding legal regulations, e.g. Patent of Toleration, Serfdom Patent, etc.
