Context paragraphs:
Fearn (letter): Fearn is the Irish name of the third letter of the Ogham alphabet, ᚃ, meaning "alder-tree".  In Old Irish, the letter name was Fern, which is related to Welsh "gwern(en)".  Its Primitive Irish root was *"wernā" and its phonetic value then was [w].  Its Old Irish and modern phonetic value is [f].

VMAQT-1: Marine Tactical Electronic Warfare Training Squadron 1 (VMAQT-1) is a United States Marine Corps electronic warfare training squadron consisting of EA-6B Prowler jets.  The squadron is based at Marine Corps Air Station Cherry Point, North Carolina and falls under the command of Marine Aircraft Group 14 (MAG-14) and the 2nd Marine Aircraft Wing (2nd MAW).  The VMAQT-1 logo is the Banshee, an Irish mythological figure foretelling death.  Its motto is “Tairngreacht Bas,” Gaelic for “Death Foretold.”

Kjartan: Kjartan (] ; ] ) is a masculine given name found in the Nordic countries, and is most prominently in Iceland and Norway.  The Old Norse name "Kjartan " was a shortening of "Mýrkjartan ", from Old Irish: "Muirchertach" , the name of an Irish king whose daughter Melkorka (Old Irish "Mael Curcaigh ", "servant of Curcach") was brought to Iceland as a slave.  The Irish name Muirchertach, meaning "mariner", is modernised to "Muircheartach ", anglicised as Murtagh.

Conn (name): Conn is a masculine English- and Irish-language given name, as well as an English-language surname.  The origin of the given name is uncertain.  It may be related to the Old Irish "cond" ("intellect" or "mind"), or perhaps to the Old Irish "cenn" ("head", "chief").  The latter word-origin may have resulted from a popular, but incorrect etymology, applied to the Old Irish terms "Leth Cuinn" and "Dál Cuinn"; these terms originally meant "half of the chief" and "tribe of the chief" but were mistakenly regarded to mean "half of "Conn"" and "tribe of "Conn"".  In some cases the given name is as a short form of non Irish-language names that begin with the first syllable "Con-" (such as the names "Conor" and "Connor").

Kevin: Kevin ( ) is the anglicized form of the Irish masculine given name Caoimhín (] , Middle Irish: "Caoimhghín" ] , Old Irish: "Cóemgein" ] , latinized "Coemgenus"), composed of Irish "" (Old Irish "cóem") "dear; noble" and "-gin" (Old Irish "gein") "birth".

Old Irish: Old Irish (Old Irish: "Goídelc" ; Irish: "Sean-Ghaeilge" ; Scottish Gaelic: "Seann Ghàidhlig" ; Manx: "Shenn Yernish" ; sometimes called Old Gaelic) is the name given to the oldest form of the Goidelic languages for which extensive written texts are extant.  It was used from 600 to 900.  The primary contemporary texts are dated 700–850; by 900 the language had already transitioned into early Middle Irish.  Some Old Irish texts date from the 10th century, although these are presumably copies of texts composed at an earlier time period.  Old Irish is thus the ancestor of Modern Irish, Manx, and Scottish Gaelic.

John Strachan (linguist): John Strachan (1862–1907) was a scholar of Sanskrit, Ancient Greek and the Celtic languages.  He was a professor at Owens College and the Victoria University of Manchester.  He is best remembered for the "Thesaurus Palaeohibernicus", a collection of material in Old Irish that he edited together with Whitley Stokes, and for the textbook "Old Irish Paradigms and Selections from the Old Irish Glosses", first published in 1904–05 and later revised by Osborn Bergin.  Both of these works are still in print.

Ogham: Ogham ( ; Modern Irish ] or ] ; Old Irish: "ogam" ] ) is an Early Medieval alphabet used to write the early Irish language (in the "orthodox" inscriptions, 1st to 6th centuries AD), and later the Old Irish language (scholastic ogham, 6th to 9th centuries).  There are roughly 400 surviving orthodox inscriptions on stone monuments throughout Ireland and western Britain; the bulk of which are in southern Munster.  The largest number outside Ireland are in Pembrokeshire, Wales.

Banshee: A banshee ( ; Modern Irish "bean sí", from Old Irish: "ban síde" , ] , "woman of the fairy mound" or "fairy woman") is a female spirit in Irish mythology who heralds the death of a family member, usually by shrieking or keening.  Her name is connected to the mythologically-important tumuli or "mounds" that dot the Irish countryside, which are known as síde (singular "síd") in Old Irish.

Midir: In the Mythological Cycle of early Irish literature, Midir (Old Irish) or Midhir (Modern Irish) was a son of the Dagda of the Tuatha Dé Danann.  After the Tuatha Dé were defeated by the Milesians, he lived in the of Brí Léith (believed to be Ardagh Hill, Co.  Longford).  In the First Recension of the "Lebor Gabála", Midir of Brí Léith is made the "son of Induí son of Échtach son of Etarlam".  The name Midir may come from the old Irish word for a judge, midithir.
