Question: What has a suprasegmental feature known as stød which is a kind of laryngeal phonation that is used phonemically, the first person to describe this in In 1743 was a Danish philologist who wrote several highly insightful treatises on Danish and Latin?

full_context: Document 1: Peder Syv: Peder Pedersen Syv (also spelled Siuf) or in Latin Petrus Petri Septimius (February 22, 1631 – February 17, 1702) was a Danish philologist, folklorist and priest, known for his collections of Danish proverbs and folksongs, and his contributions to the development of Danish as a written language.
Document 2: Stød: Stød (] ) is a suprasegmental unit of Danish phonology (represented in IPA as or as ⟨⟩ ), which in its most common form is a kind of creaky voice (laryngealization), but it may also be realized as a glottal stop, especially in emphatic pronunciation. Some dialects of Southern Danish realize "stød" in a way that is more similar to the tonal word accents of Norwegian and Swedish. In much of Zealand it is regularly realized as something reminiscent of a glottal stop. A probably-unrelated glottal stop, with quite different distribution rules, occurs in Western Jutland and is known as the "vestjysk stød" ("West Jutland "stød""). Because Dania, the phonetic alphabet based on IPA that is designed specifically for Danish, uses the IPA character ⟨⟩ (intended as a glottal stop) broadly to transcribe "stød", it may be mistaken for a consonant, rather than a suprasegmental phonation.
Document 3: Danish dialects: Danish dialects are the regional and local varieties of the Danish language. Danish dialects can be divided into the traditional dialects, which differ from modern Standard Danish in both phonology and grammar, and the Danish accents, which are local varieties of the Standard language distinguished mostly by pronunciation and local vocabulary colored by traditional dialects. Traditional dialects are now mostly extinct in Denmark, with only the oldest generations still speaking them. Danish traditional dialects are divided into three main dialect areas: Jutlandic dialect, Insular Danish and Bornholmian. Bornholmian is the only Eastern Danish dialect spoken in Denmark, since the other Eastern Danish dialects were spoken in areas ceded to Sweden and subsequently assimilated to Standard Swedish. Jutlandic is further divided into Southern Jutlandic and Northern Jutlandic, with Northern Jutlandic subdivided into North Jutlandic and West Jutlandic. Insular Danish is divided into Zealand, Funen, Møn and Lolland-Falster dialect areas - each with addition internal variation.
Document 4: Danish Sign Language family: The Danish Sign Language family comprises three languages: Danish Sign Language, Norwegian Sign Language (including Malagasy Sign Language) and Icelandic Sign Language. It itself is a sub-language family within the larger French Sign Language family.
Document 5: Lis Jacobsen: Elisabeth (Lis) Jacobsen, née Rubin, (1882–1961) was a Danish philologist, archaeologist and writer. She is remembered first and foremost for her research and publications on the history of the Danish language but she was also an expert runologist who published a comprehensive analysis of all known runic inscriptions in Denmark. From 1911, Jacobsen played a major role in all fields of research related to the Danish language.
Document 6: Jens Høysgaard: Jens Pedersen Høysgaard (December 25, 1698 – April 21, 1773) was a Danish philologist, caretaker at the University of Copenhagen from 1737–1759, and bell-ringer at Trinitatis Church. In spite of never holding an academic post, he wrote several highly insightful treatises on Danish and Latin. Today, his work on Danish is considered the best of the early grammatical analyses of the Danish language. In 1743, he was the first to describe the stød, an important aspect of Danish phonology, in his "Concordia res parvæ crescunt, eller Anden Prøve af Dansk Orthographie", in which he also introduced the letter Å å to the Danish alphabet.
Document 7: Rasmus Rask: Rasmus Kristian Rask (] ; born Rasmus Christian Nielsen Rasch; sometimes rendered as Erasmus Rask; 22 November 1787 – 14 November 1832) was a Danish linguist and philologist. He wrote several grammars and worked on comparative phonology and morphology. Rask traveled extensively to study languages, first to Iceland, where he wrote the first grammar of Icelandic, and later to Russia, Persia, India, and Ceylon (now Sri Lanka). Shortly before his death, he was hired as professor of Eastern languages at the University of Copenhagen. Rask is especially known for his contributions to comparative linguistics, including an early formulation of what would later be known as Grimm's Law.
Document 8: Jacob Baden: Jacob Baden (4 May 1735 – 5 July 1804), was a Danish philologist, pedagogue, and critic. He was professor of rhetoric and the Latin language at University of Copenhagen in 1779. He was the first person to lecture on Danish grammar at the university between 1782 and 1783,He was the editor of the "University Journal" from 1793 to 1801.
Document 9: Copenhagen School (linguistics): The Copenhagen School, officially the Linguistic Circle of Copenhagen (French: "Cercle Linguistique de Copenhague"), is a group of scholars dedicated to the study of linguistics. It was founded by Louis Hjelmslev (1899–1965) and Viggo Brøndal (1887–1942). In the mid twentieth century the Copenhagen school was one of the most important centres of linguistic structuralism together with the Geneva School and the Prague School. In the late 20th and early 21st century the Copenhagen school has turned from a purely structural approach to linguistics to a functionalist one, Danish functional grammar, which nonetheless incorporates many insights from the founders.
Document 10: Danish phonology: The phonology of Danish is similar to that of the other Scandinavian languages such as Swedish and Norwegian, but it also has distinct features setting it apart from the phonologies of its most closely related languages. For example Danish has a suprasegmental feature known as stød which is a kind of laryngeal phonation that is used phonemically. It also exhibits extensive lenition of plosives, which is noticeably more common than in the neighboring languages. Because of that and a few other things, spoken Danish is rather hard to understand for Norwegians and Swedes, although they can easily read it.
Document 11: Swedish language: Swedish (   ] ) is a North Germanic language, spoken natively by more than 9 million people predominantly in Sweden (as sole official language) and parts of Finland, where it has equal legal standing with Finnish. It is largely mutually intelligible with Norwegian and Danish. Swedish is a descendant of Old Norse, the common language of the Germanic peoples living in Scandinavia during the Viking Era. It is currently the largest of the North Germanic languages by number of speakers.
Document 12: Æ: Æ (minuscule: æ) is a grapheme named æsc or ash, formed from the letters "a" and "e", originally a ligature representing the Latin diphthong "ae". It has been promoted to the full status of a letter in the alphabets of some languages, including Danish, Norwegian, Icelandic, and Faroese. As a letter of the Old English Latin alphabet, it was called "æsc" ("ash tree") after the Anglo-Saxon futhorc rune ᚫ () which it transliterated; its traditional name in English is still ash . It was also used in Old Swedish before being changed to ä. Variants include Ǣ ǣ Ǽ ǽ æ̀.
Document 13: Phonemic contrast: Phonemic contrast refers to a minimal phonetic difference, that is, small differences in speech sounds, that makes a difference in how the sound is perceived by listeners, and can therefore lead to different mental lexical entries for words. For example, whether a sound is voiced or unvoiced (consider /b/ and /p/ in English) matters for how a sound is perceived in many languages, such that changing this phonetic feature can yield a different word (consider "pat" and "bat" in English); see Phoneme. Other examples in English of a phonemic contrast would be the difference between "leak" and "league;" the minimal difference of voicing between [k] and [g] does lead to the two utterances being perceived as different words. On the other hand, an example that is not a phonemic contrast in English is the difference between [sit] and [siːt] . In this case the minimal difference of vowel length is not a contrast in English and so those two forms would be perceived as different pronunciations of the same word "seat".
Document 14: Gyldendal: Gyldendalske Boghandel, Nordisk Forlag A/S, usually referred to simply as Gyldendal (] ; Nasdaq: GYLD A , ) is a Danish publishing house. Founded in 1770 by Søren Gyldendal, it is the oldest and largest publishing house in Denmark, offering a wide selection of books including fiction, non-fiction and dictionaries. Prior to 1925, it was also the leading publishing house in Norway, and it published all of Henrik Ibsen's works. In 1925, a Norwegian publishing house named Gyldendal Norsk Forlag ("Gyldendal Norwegian Publishing House") was founded, having bought rights to Norwegian authors from Gyldendal.
Document 15: Perkerdansk: Perkerdansk or Immigrant Danish is a multi-ethnolect spoken in Denmark, a variety of Danish associated primarily with youths of middle eastern ethnic background. It is a contact variety that includes features of Danish as well as Arabic, Turkish, English and other immigrant languages. Particularly common in urban areas with high densities of immigrant populations, its features have also spread to general youth language in Denmark.
