Authority is commonly understood as the legitimate power of a person or group over other people. In a civil state, authority may be practiced by legislative, executive, and judicial branches of government, each of which has authority and is an authority. The term "authority" has many nuances and distinctions within various academic fields ranging from sociology to political science.

In the exercise of governance, the terms authority and power are inaccurate synonyms. The term authority identifies the political legitimacy, which grants and justifies rulers' right to exercise the power of government; and the term power identifies the ability to accomplish an authorized goal, either by compliance or by obedience; hence, authority is the power to make decisions and the legitimacy to make such legal decisions and order their execution.

A classic is an outstanding example of a particular style; something of lasting worth or with a timeless quality; of the first or highest quality, class, or rank – something that exemplifies its class. The word can be an adjective (a classic car) or a noun (a classic of English literature). It denotes a particular quality in art, architecture, literature, design, technology, or other cultural artifacts. In commerce, products are named 'classic' to denote a long-standing popular version or model, to distinguish it from a newer variety. Classic is used to describe many major, long-standing sporting events. Colloquially, an everyday occurrence (e.g. a joke or mishap) may be described in some dialects of English as 'an absolute classic'.

"Classic" should not be confused with classical, which refers specifically to certain cultural styles, especially in music and architecture: styles generally taking inspiration from the Classical tradition, hence classicism.

Personalization (broadly known as customization) consists of tailoring a service or product to accommodate specific individuals. It is sometimes tied to groups or segments of individuals. Personalization involves collecting data on individuals, including web browsing history, web cookies, and location. Various organizations use personalization (along with the opposite mechanism of popularization) to improve customer satisfaction, digital sales conversion, marketing results, branding, and improved website metrics as well as for advertising. Personalization acts as a key element in social media and recommender systems. Personalization influences every sector of society — be it work, leisure, or citizenship.

Polo or Chovgan (Persian: چوگان) is a ball game that is played on horseback, a traditional field sport and one of the world's oldest known team sports. It originated in ancient Persia (modern-day Iran), dating back over 2,000 years. Initially played by Persian nobility as a training exercise for cavalry units, polo eventually spread to other parts of the world. The game is played by two opposing teams with the objective of scoring using a long-handled wooden mallet to hit a small hard ball through the opposing team's goal. Each team has four mounted riders, and the game usually lasts one to two hours, divided into periods called chukkas or chukkers.

Polo has been called "the sport of kings", and has become a spectator sport for equestrians and high society, often supported by sponsorship. The progenitor of polo and its variants existed from the 6th century BC to the 1st century AD, as an equestrian game played by the Iranian. In Persia, where the sport evolved and developed, it was at first a training game for cavalry units, usually the royal guard or other elite troops. It is now popular around the world, with well over 100 member countries in the Federation of International Polo, played professionally in 16 countries, and was an Olympic sport from 1900 to 1936.

Arena polo is an indoor or semi-outdoor variant with similar rules, and is played with three riders per team. The playing field is smaller, enclosed and usually of compacted sand or fine aggregate, and often indoors. Arena polo has more maneuvering due to space limitations, and uses an air-inflated ball slightly larger than the hard solid ball used in field polo. Standard mallets are used, though slightly larger-head arena mallets are an option.

A port is a maritime facility comprising one or more wharves or loading areas, where ships load and discharge cargo and passengers. Although usually situated on a sea coast or estuary, ports can also be found far inland, such as Hamburg, Manchester and Duluth; these access the sea via rivers or canals. Because of their roles as ports of entry for immigrants as well as soldiers in wartime, many port cities have experienced dramatic multi-ethnic and multicultural changes throughout their histories.

Ports are extremely important to the global economy; 70% of global merchandise trade by value passes through a port. For this reason, ports are also often densely populated settlements that provide the labor for processing and handling goods and related services for the ports. Today by far the greatest growth in port development is in Asia, the continent with some of the world's largest and busiest ports, such as Singapore and the Chinese ports of Shanghai and Ningbo-Zhoushan. As of 2020, the busiest passenger port in Europe is the Port of Helsinki in Finland. Nevertheless, countless smaller ports do exist that may only serve their local tourism or fishing industries.

Ports can have a wide environmental impact on local ecologies and waterways, most importantly water quality, which can be caused by dredging, spills and other pollution. Ports are heavily affected by changing environmental factors caused by climate change as most port infrastructure is extremely vulnerable to sea level rise and coastal flooding. Internationally, global ports are beginning to identify ways to improve coastal management practices and integrate climate change adaptation practices into their construction.
