A language border or language boundary is the line separating two language areas.
 The term is generally meant to imply a lack of mutual intelligibility between the two languages.
 If two adjacent languages or dialects are mutually intelligible, no firm border will develop, because the two languages can continually exchange linguistic inventions; this is known as a dialect continuum.
 A "language island" is a language area that is completely surrounded by a language border.
The Tsouic languages (also known as the Central Formosan languages) are three Formosan languages, Tsou proper and the Southern languages Kanakanabu and Saaroa.
 The Southern Tsouic languages of Kanakanabu and Saaroa have the smallest phonemic inventories out of all the Formosan languages, with each language having only 13 consonants and 4 vowels (Blust 2009:165).
 These two languages are highly endangered, as many Southern Tsouic speakers are shifting to Bunun and Mandarin Chinese.

Tittenhurst Park is a Grade II listed early Georgian country house in an estate of 72 acre off London Road at Beggar's Bush near Ascot and over the parish border into Sunningdale, both in the English county of Berkshire.
 It was famously the home of musicians John Lennon and Yoko Ono from the late summer of 1969 until August 1971, and then the home of Ringo Starr and family until the late 1980s.
 Starr sold the property to Sheikh Zayed bin Sultan Al Nahyan, President of the United Arab Emirates, in 1989.
Imagine is a 1972 television film by John Lennon and Yoko Ono, filmed mostly at their Tittenhurst Park home in Ascot, England, during 1971, and intended for television.
 All the songs from Lennon's "Imagine" album appear in the soundtrack, and also the songs "Mrs. Lennon" and "Don't Count the Waves", from Ono's album "Fly".
Simultaneous bilingualism is a form of bilingualism that takes place when a child becomes bilingual by learning two languages from birth.
 According to Annick De Houwer, in an article in "The Handbook of Child Language", simultaneous bilingualism takes place in "children who are regularly addressed in two spoken languages from before the age of two and who continue to be regularly addressed in those languages up until the final stages" of language development.
 Both languages are acquired as first languages.
 This is in contrast to sequential bilingualism, in which the second language is learned not as a native language but a foreign language.
A bilingual name is a name of a person that is spelled, if not pronounced, exactly the same in two languages.
 The speakers of a certain language usually have names that do not exist in another language.
 Even when the name has a common root or refers to the same historic or religious figure, different languages will spell and pronounce the name in a unique way.
 Thus a name with identical spelling in two languages may be of interest to parents of Third Culture Kids, or immigrants.
Annie Miner Peterson (1860-1939) was a Coos Indian from the U.S. state of Oregon who was a cultural and linguistic consultant to Melville Jacobs, an anthropologist at the University of Washington.
 In 1933 while searching for a suitable consultant in the Hanis Coos language from among the eight or ten elderly Coos Indians who were still fluent at that time, Jacobs discovered that Peterson was fluent not only in Hanis, but also in Miluk Coos, a Penutian language thought to have been extinct for at least fifteen years.
 Through the summers of 1933 and 1934, Jacobs interviewed Peterson in those two languages, collecting 32 Coos myth texts in Miluk, eight in Hanis, and two in both Hanis and Miluk for comparison of the two languages.
 Wax-cylinder phonograph recordings were also taken of the myths and songs during both years.
 In addition, Jacobs collected from Peterson a large number of narrative and ethnologic texts in Miluk, a smaller number in Hanis, and eight texts in both Hanis and Miluk.
 The narrative and ethnologic texts were published in 1939; the myth texts in 1940.
The Wentworth Estate is a 1920s-founded estate of houses and woodland across 7 km2 (a typical small village size in England) around the home of the first Ryder Cup, Wentworth Club.
 It is in Virginia Water, Surrey, England and forms one of Europe's premier residential areas on a gently undulating area of coniferous heath, a nationally rare soil type.
 Most of its invariably large plots have homes built from scratch or rebuilt after 1930 in a range of styles from the ornate multi-chimneyed Arts and Crafts movement of the earliest properties through Neo-Georgian and colonial revival to the postmodern simple style as in the recording studios at John Lennon's Tittenhurst Park (1971) in the adjoining parish of Sunninghill and Ascot, the north of which, with parts of Windsor, Winkfield and Virginia Water is the main piece of Crown Estate in South-East England, Windsor Great Park.
Muhakamat al-Lughatayn (Arabic: محاكمة اللغتين‎ ‎ , literally "Judgment between the Two Languages" or "The Comparison of the Two Languages"; Uzbek: "Muxokamat allugatayn" ), was one of Mir Ali-Shir Nava'i's masterpieces.
 Completed in December 1499, he believed that the Chagatai Turkic language was superior to Persian for literary purposes, and defended this belief in his work.
 It was the writer's last definitive statement on the subject dearest to his heart, and the "Muhakamat" is a perfect example of an author's final work acting also as his last will and testament which was to emphasize the importance of his native language.
