Week News Abstract For SFP Series in 10GTEK:Etymology of Cymru

The modern Welsh name for themselves is Cymry, and Cymru is Welsh for "Land of the Cymry". The etymological origin of Cymry is from the Brythonic word combrogi, meaning "fellow-countrymen".[10] The use of the word Cymry as a self-designation derives from the post-Roman Era relationship of the Welsh with the Brythonic-speaking peoples of northern England and southern Scotland, the peoples of Yr Hen Ogledd (English: The Old North). In its original use, it amounted to a self-perception that the Welsh and the "Men of the North" were one people, exclusive of all others.[11] In particular, the term was not applied to the Cornish or the Breton peoples, who are of similar heritage, culture, and language to both the Welsh and the Men of the North. The word came into use as a self-description probably before the 7th century.[12] It is attested in a praise poem to Cadwallon ap Cadfan (Moliant Cadwallon, by Afan Ferddig) c. 633. In Welsh literature, the word Cymry was used throughout the Middle Ages to describe the Welsh, though the older, more generic term Brythoniaid continued to be used to describe any of the Britonnic peoples (including the Welsh) and was the more common literary term until c. 1100. Thereafter Cymry prevailed as a reference to the Welsh. Until c. 1560 Cymry was used indiscriminately to mean either the people (Cymry) or their homeland (Cymru).

The Latinised forms of these names are Cambrian or Cambric ("Welsh") and Cambria ("Wales"). They survive as lesser-used alternative names for Wales, Welsh and the Welsh people. Examples include the Cambrian Mountains (which cover most of Wales), the newspaper Cambrian News, as well as the organisations Cambrian Airways, Cambrian Railways and Cambrian Archaeological Association. Outside Wales, this form survives as the name of Cumbria in North West England, which was once a part of Yr Hen Ogledd. This form also appears at times in literary references, perhaps most notably in the pseudohistorical Historia Regum Britanniae of Geoffrey of Monmouth, where the character of Camber is described as the eponymous King of Cymru.Iron is a chemical element with the symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal in the first transition series. It is the most common element (by mass) forming the planet Earth as a whole, forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. Iron's very common presence in rocky planets like Earth is due to its abundant production as a result of fusion in high-mass stars, where the production of nickel-56 (which decays to iron) is the last nuclear fusion reaction that is exothermic. This allows radioactive nickel to become the last element to be produced before collapse of a supernova leads to events that scatters this precursor radionuclide of iron into space.
