A marketplace, market place, or just market, is a location where people regularly gather for the purchase and sale of provisions, livestock, and other goods. In different parts of the world, a marketplace may be described as a souk (from Arabic), bazaar (from Persian), a fixed mercado (Spanish), itinerant tianguis (Mexico), or palengke (Philippines). Some markets operate daily and are said to be permanent markets while others are held once a week or on less frequent specified days such as festival days and are said to be periodic markets. The form that a market adopts depends on its locality's population, culture, ambient, and geographic conditions. The term market covers many types of trading, such as market squares, market halls, food halls, and their different varieties. Thus marketplaces can be both outdoors and indoors, and in the modern world, online marketplaces.

Markets have existed for as long as humans have engaged in trade. The earliest bazaars are believed to have originated in Persia, from where they spread to the rest of the Middle East and Europe. Documentary sources suggest that zoning policies confined trading to particular parts of cities from around 3000 BCE, creating the conditions necessary for the emergence of a bazaar. Middle Eastern bazaars were typically long strips with stalls on either side and a covered roof designed to protect traders and purchasers from the fierce sun. In Europe, informal, unregulated markets gradually made way for a system of formal, chartered markets from the 12th century. Throughout the medieval period, increased regulation of marketplace practices, especially weights and measures, gave consumers confidence in the quality of market goods and the fairness of prices. Around the globe, markets have evolved in different ways depending on local ambient conditions, especially weather, tradition, and culture. In the Middle East, markets tend to be covered, to protect traders and shoppers from the sun. In milder climates, markets are often open air. In Asia, a system of morning markets trading in fresh produce and night markets trading in non-perishables is common.

A caravan (from Persian کاروان kârvân) is a group of people traveling together, often on a trade expedition. Caravans were used mainly in desert areas and throughout the Silk Road, where traveling in groups helped in defense against bandits as well as in improving economies of scale in trade.

Historically, a master craftsman or master tradesman (sometimes called only master or grandmaster) was a member of a guild. The title survives as the highest professional qualification in craft industries.

In the European guild system, only masters and journeymen were allowed to be members of the guild. An aspiring master would have to pass through the career chain from apprentice to journeyman before he could be elected to become a master craftsman. He would then have to produce a sum of money and a masterpiece before he could actually join the guild. If the masterpiece was not accepted by the masters, he was prohibited to join the guild and possibly remained a journeyman for the rest of his life.

A katib (Arabic: كَاتِب, kātib) is a writer, scribe, or secretary in the Arabic-speaking world, Persian World, and other Islamic areas as far as the Indian subcontinent. In North Africa, the local pronunciation of the term also causes it to be written ketib. Duties comprised reading and writing correspondence, issue instructions at the command of the person in charge and archiving documentation.

The word comes probably from Arabic kitāb (book), and perhaps imported from the Northern Aramaic neighbors of the Arabs. It is a pre-Islamic concept, encountered in the work of ancient Arab poets. The art of writing, although present in all part of Arabia, was apparently accomplishment of the few. Among the Companions of Medina, about ten are mentioned as katibs. With the embrace of Islam, the office of katib became a post of great honor. By this time, on the model of the Persian chancellery, a complicated system of government offices had developed, each branch of governmental, religious, civic, or military entity had its own katib. Thus, the term became widely encountered in conjunction with other words in order to derive a more specific secretary position, i.e. katib dīwān - secretary in the financial bureaus, katib al-sirr - chancellery secretary or chief-secretary, katib al-djaysh - secretary of the army, and so on.
