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.
Old Frisian is a West Germanic language spoken between the 8th and 16th centuries in the area between the Rhine and Weser on the European North Sea coast.
 The Frisian settlers on the coast of South Jutland (today's Northern Friesland) also spoke Old Frisian but no medieval texts of this area are known.
 The language of the earlier inhabitants of the region between the Zuiderzee and Ems River (the Frisians mentioned by Tacitus) is attested in only a few personal names and place-names.
 Old Frisian evolved into Middle Frisian, spoken from the 16th to the 19th century.
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.
A domain-specific language (DSL) is a computer language specialized to a particular application domain.
 This is in contrast to a general-purpose language (GPL), which is broadly applicable across domains.
 There is a wide variety of DSLs, ranging from widely used languages for common domains, such as HTML for web pages, down to languages used by only one or a few pieces of software, such as Emacs Lisp for GNU Emacs and XEmacs.
 DSLs can be further subdivided by the kind of language, and include domain-specific "markup" languages, domain-specific "modeling" languages (more generally, specification languages), and domain-specific "programming" languages.
 Special-purpose computer languages have always existed in the computer age, but the term "domain-specific language" has become more popular due to the rise of domain-specific modeling.
 Simpler DSLs, particularly ones used by a single application, are sometimes informally called mini-languages.
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.
Language immersion, or simply immersion, is a technique used in bilingual language education in which two languages are used for instruction in a variety of topics, including math, science, or social studies.The languages used for instruction are referred to as the L1 and the L2 for each student, with L1 being the native language of the student and L2 being the second language to be acquired through immersion programs and techniques.
 There are different contexts for language immersion, such as age of students, class time spent in the L2, subjects taught, and the level of participation by the native L1 speakers.
The Caistor-by-Norwich astralagus is a roe deer astragalus found in an urn at Caistor St. Edmund, Norfolk, England.
 The astragalus is inscribed with a 5th-century Elder Futhark inscription, reading raïhan "roe".
 The inscription is the earliest found in England, and predates the evolution of the specifically Anglo-Frisian Futhorc.
 As the urn was found in a cemetery that indicated some Scandinavian influence, it has been suggested that the astragalus may be an import, perhaps brought from Denmark in the earliest phase of the Anglo-Saxon settlement of Britain.
 The inscription is an important testimony for the Eihwaz rune and the treatment of Proto-Germanic "*ai".
 The "h" rune has the Nordic single-bar shape , not the Continental double-bar which was later adopted in the Anglo-Frisian runes.
Sri Lankan literature is the literary tradition of Sri Lanka.
 The largest part of Sri Lankan literature was written in the Sinhala language, but there is a considerable amount of works in other languages used in Sri Lanka over the millennia (including Pāli, Tamil, and English).
 However, the languages used in ancient times were much different than the language used in Sri Lanka now.
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.
Anglo-Saxon runes are runes used by the early Anglo-Saxons as an alphabet in their writing.
 The characters are known collectively as the futhorc (or "fuþorc"), from the Old English sound values of the first six runes.
 The futhorc was a development from the 24-character Elder Futhark.
 Since the futhorc runes are thought to have first been used in Frisia before the Anglo-Saxon settlement of Britain, they have also been called Anglo-Frisian runes.
 They were likely used from the 5th century onward, recording Old English and Old Frisian.

Question: What two languages used anglo-frisian runes?
Answer: Old English and Old Frisian
