Roshandan
A roshandan (Hindi/Urdu: रोशनदान or روشندان) is a feature of many dwelling structures in North India and Pakistan that is a combined skylight and ventilating window. ''Roshandans'' are usually located high on a room's walls, and often on top of windows. They are essentially smaller windows that swivel open when needed. Smaller ''roshandans'' are sometimes called ''roshandanis''. The high location of ''roshandans'' means that, for part of the summer (except for the months when the Loo winds blow in the region), they can be kept open to allow heated air just below the ceiling to escape while retaining relatively cooler air inside. In wintertime, they are kept shut and used purely as skylights. Etymology The term ''roshandan'' literally means "that which has/admits light" in several Indo-Aryan languages, derived from Persian. Though the word ''roshandan'' is often translated to ''ventilator'' in English in the Indian subcontinent The Indian subcontinent is ...

Skylight
A skylight (sometimes called a rooflight) is a light-permitting structure or window, usually made of transparent or translucent glass, that forms all or part of the roof space of a building for daylighting and ventilation purposes. History Open skylights were used in Ancient Roman architecture, such as the oculus of the Pantheon. Glazed 'closed' skylights have been in use since the Industrial Revolution made advances in glass production manufacturing. Mass production units since the mid-20th century have brought skylights to many uses and contexts. Energy conservation has brought new motivation, design innovation, transmission options, and efficiency rating systems for skylights. Prior to the Industrial Revolution, it was Spain and France that probably had the leading technology in architectural glass. One of the earliest forms of glass skylight can be seen at the Burgos Cathedral in the Chapel of the Constable. Other early form of glass skylight can be seen at the Palace of ...

Loo (wind)
The Loo ( hi, लू, Urdu: لو) is a strong, dusty, gusty, hot and dry summer wind from the west which blows over the Indo-Gangetic Plain region of North India and Pakistan. It is especially strong in the months of May and June. Due to its very high temperatures (45 °C–50 °C or 115 °F–120 °F), exposure to it often leads to fatal heatstrokes. Since it causes extremely low humidity and high temperatures, the ''Loo'' also has a severe drying effect on vegetation leading to widespread browning in the areas affected by it during the months of May and June. Origin and ending The Loo mainly originates in the large desert regions of the northwestern Indian subcontinent: the Great Indian Desert, the Cholistan Desert and the desert areas of Southern Balochistan. The Loo ends in late summer, with the arrival of the Indian monsoon. In some areas of North India and Pakistan, there are brief, but violent, dust storms known as Kali Andhi (or ''black Storm'') b ...

English Language
English is a West Germanic language of the Indo-European language family, with its earliest forms spoken by the inhabitants of early medieval England. It is named after the Angles, one of the ancient Germanic peoples that migrated to the island of Great Britain. Existing on a dialect continuum with Scots, and then closest related to the Low Saxon and Frisian languages, English is genealogically West Germanic. However, its vocabulary is also distinctively influenced by dialects of France (about 29% of Modern English words) and Latin (also about 29%), plus some grammar and a small amount of core vocabulary influenced by Old Norse (a North Germanic language). Speakers of English are called Anglophones. The earliest forms of English, collectively known as Old English, evolved from a group of West Germanic (Ingvaeonic) dialects brought to Great Britain by Anglo-Saxon settlers in the 5th century and further mutated by Norse-speaking Viking settlers starting in the 8 ...
