Name of Jersey
Jersey ( , ; ), officially the Bailiwick of Jersey (), is a British crown dependency. Historic mentions. The Channel Islands are mentioned in the Antonine Itinerary as the following: "Sarnia", "Caesarea", "Barsa", "Silia" and "Andium", but Jersey cannot be identified specifically because none corresponds directly to the present names. Furthermore, later records evoke "Angia" (also spelled "Agna" ). "Andium" is a Latinized version of the Gaulish (Celtic) "*Andion", with "and-" the Gaulish intensive prefix meaning "very", "much", "big". "Andium" roughly translates as "big Island", Jersey being the largest of the Channel Islands. The spelling "Angia" could be an ultimate development of  *Andia. Some others identify it as "Caesarea", a late recorded Roman name influenced by the Old English suffix "-ey" for "island"; this is plausible if, in the regional pronunciation of Latin, "Caesarea" was not but . Another theory is that the variation of the "J" sound today could be connected with phonetical cousins "g" and "k" (International Phonetic Alphabet) through variable pronunciations based on similar spelling. Theoretically, if Caesarea was originally pronounced with a "k", that may have naturally developed into a "g" sound for locals (or foreigners), making Gersei, Gersoi, or the other spellings relatable. Because "g" is pronounced as  both a hard guttural "g" as in "go" and a soft "j" as in "gym" or "gem", the spelling of Jersey could be a result of the variance in its pronunciation. The name "Caesarea" has been used as the Latin name for Jersey (also in its French version "Césarée") since William Camden's "Britannia" (published in 1586), and is used in titles of associations and institutions today. The Latin name "Caesarea" was also applied to the colony of New Jersey as "Nova Caesarea". "Angia" could be a misspelling for "*Augia", that is the Latinized form of Germanic "*aujō" (> Old  English "ī(e)ġ" > is-land), that could have extended before the Viking Age along the coast of France, as for île d'Yeu ("Augia", "Insula Oya") or Oye-Plage ("Ogia" 7th century) and constitutes the suffix "-ey" in Jersey, Guernsey ("Greneroi"), Alderney ("Alneroi") and Chausey ("Calsoi"). Chausey can be compared with Cholsey (GB, Berkshire, "Ċeolesiġ" 891), interpreted by Eilert Ekwall as ""Ċeola" 's island". The ending "-ey" denotes an island. These "-ey" names could have been reinforced by the Viking heritage, because "-ey" is similar, so that it is possible to interpret the first part of the toponym as an Old  Norse element. The source of it is unclear. Scholars surmise it derives from "hjörr" (Old Norse for "sword") or "jarl" (earl), or perhaps a personal name, "Geirr" ("Geirr's Island"). The personal name explanation is accepted by Richard Coates, who also discusses the names of the other Channel Islands.
