Numeral prefix

Numeral or number prefixes are prefixes derived from numerals or occasionally other numbers. In English and other European languages, they are used to coin numerous series of words, such as unicycle – bicycle – tricycle, dyad – triad – decade, biped – quadruped, September – October – November – December, decimal – hexadecimal, sexagenarian – octogenarian, centipede – millipede, etc. There are two principal systems, taken from Latin and Greek, each with several subsystems; in addition, Sanskrit occupies a marginal position. There is also an international set of metric prefixes, which are used in the metric system, and which for the most part are either distorted from the forms below or not based on actual number words.

Table of number prefixes in English

In the following prefixes, a final vowel is normally dropped before a root that begins with a vowel, with the exceptions of bi-, which is bis- before a vowel, and of the other monosyllables, du-, di-, dvi-, tri-, which are invariable.

Uni (inhabited locality)

Hector

In Greek mythology, Hector (Ἕκτωρ Hektōr, pronounced [héktɔːr]) was a Trojan prince and the greatest fighter for Troy in the Trojan War. As the first-born son of King Priam and Queen Hecuba, who was a descendant of Dardanus and Tros, the founder of Troy, he was a prince of the royal house and the heir apparent to his father's throne. He was married to Andromache, with whom he had an infant son, Scamandrius (whom the people of Troy called Astyanax). He acted as leader of the Trojans and their allies in the defense of Troy, "killing 31,000 Greek fighters", offers Hyginus. During the European Middle Ages, Hector figures as one of the Nine Worthies noted by Jacques de Longuyon, known not only for his courage but also for his noble and courtly nature. Indeed, Homer places Hector as peace-loving, thoughtful as well as bold, a good son, husband and father, and without darker motives. James Redfield writes of Hector as a "martyr to loyalties, a witness to the things of this world, a hero ready to die for the precious imperfections of ordinary life."

Hector (cloud)

Hector is the name given to a cumulonimbus, or thundercloud, that forms regularly nearly every afternoon on the Tiwi Islands, Northern Territory, Australia, from approximately September to March each year. Hector, or sometimes "Hector the Convector", is known as one of the world's most consistently large thunderstorms, reaching heights of approximately 20 kilometres (66,000 ft).

History

Named by pilots during the Second World War, the recurring position of the thunderstorm made it a navigational beacon for pilots and mariners in the region. Hector is caused primarily by a collision of several sea breeze boundaries across the Tiwi Islands and is known for its consistency and intensity.Lightning rates and updraft speeds are notable aspects of this thunderstorm and during the 1990s National Geographic Magazine published a comprehensive study of the storm with pictures of damaged trees and details of updraft speeds and references to tornadic events.

Since the late 1980s the thunderstorm has been the subject of many meteorological studies, many centered on Hector itself but also utilising the consistency of the storm cell to study other aspects of thunderstorms and lightning.

Hector (1784 ship)

Hector was a Dutch 44-gun frigate launched in 1784 that the British captured in 1799. They fitted her out and transferred her to the Transport Board in 1800 under the name Pandour. She then transported troops to and from Egypt. The Royal Navy commissioned her in 1803 as HMS Pandour; she then sailed to the Leeward Islands, where she participated in the capture of Surinam. The Navy converted her to a floating battery in 1804, and transferred her to Customs as a store hulk in 1805. She was sold in 1814.

Career

The British captured Hector, and a number of other vessels, at the Nieuwe Diep during the Anglo-Russian invasion of Holland. The actual captor was HMS Circe (1785), which took possession of 13 men-of-war in all, ranging in size from 66 guns to 24, and three Indiamen. She also took possession of the Naval Arsenal and its 95 pieces of ordnance.

Hector arrived at Sheerness on 30 April 1800. The Admiralty transferred her to the Transport Board on 26 May 1801, which had her fitted en flute at Woolwich between May and July to serve as a troopship. Commander John Shortland took command in June, and sailed her to Egypt. She may have arrived in time for the Siege of Alexandria, which was fought between 17 August and 2 September 1801. Pandour was still or again there in early February 1803 as the British troops were preparing to leave in March.
