paragraph_text: Both Alsatian and Standard German were for a time banned from public life (including street and city names, official administration, and educational system). Though the ban has long been lifted and street signs today are often bilingual, Alsace-Lorraine is today very French in language and culture. Few young people speak Alsatian today, although there do still exist one or two enclaves in the Sundgau region where some older inhabitants cannot speak French, and where Alsatian is still used as the mother tongue. A related Alemannic German survives on the opposite bank of the Rhine, in Baden, and especially in Switzerland. However, while French is the major language of the region, the Alsatian dialect of French is heavily influenced by German and other languages such a Yiddish in phonology and vocabulary.

paragraph_text: Portuguese is the official language of Brazil, and is widely spoken by most of population. Brazilian Sign Language is also an official language. Minority languages include indigenous languages and languages of more recent European and Asian immigrants. The population speaks or signs approximately 210 languages, of which 180 are indigenous. Less than forty thousand people actually speak any one of the indigenous languages in the Brazilian territory.

paragraph_text: Togo is a multilingual country. According to Ethnologue, 39 distinct languages are spoken in the country, many of them by communities that number fewer than 100,000 members. Of the 39 languages, the sole official language is French. Two spoken indigenous languages were designated politically as national languages in 1975: Ewé (Ewe: Èʋegbe; French: Evé) and Kabiyé; they are also the two most widely spoken indigenous languages.

paragraph_text: In 677 (during the reign of Emperor Gaozong), Chen Zheng (陳政), together with his son Chen Yuanguang (陳元光), led a military expedition to pacify the rebellion in Fujian. They settled in Zhangzhou and brought the Middle Chinese phonology of northern China during the 7th century into Zhangzhou; In 885, (during the reign of Emperor Xizong of Tang), the two brothers Wang Chao (王潮) and Wang Shenzhi (王審知), led a military expedition force to pacify the Huang Chao rebellion. They brought the Middle Chinese phonology commonly spoken in Northern China into Zhangzhou. These two waves of migrations from the north generally brought the language of northern Middle Chinese into the Fujian region. This then gradually evolved into the Zhangzhou dialect.

paragraph_text: Ottoman Turkish was the official language of the Empire. It was an Oghuz Turkic language highly influenced by Persian and Arabic. The Ottomans had several influential languages: Turkish, spoken by the majority of the people in Anatolia and by the majority of Muslims of the Balkans except in Albania and Bosnia; Persian, only spoken by the educated; Arabic, spoken mainly in Arabia, North Africa, Iraq, Kuwait, the Levant and parts of the Horn of Africa; and Somali throughout the Horn of Africa. In the last two centuries, usage of these became limited, though, and specific: Persian served mainly as a literary language for the educated, while Arabic was used for religious rites.

paragraph_text: Sierra Leone is a multilingual country. English is the de facto official language, and Krio is the most widely spoken and is spoken in different countries.

paragraph_text: In a course at the LSA summer institute in 1991, Alan Prince and Paul Smolensky developed optimality theory—an overall architecture for phonology according to which languages choose a pronunciation of a word that best satisfies a list of constraints ordered by importance; a lower-ranked constraint can be violated when the violation is necessary in order to obey a higher-ranked constraint. The approach was soon extended to morphology by John McCarthy and Alan Prince, and has become a dominant trend in phonology. The appeal to phonetic grounding of constraints and representational elements (e.g. features) in various approaches has been criticized by proponents of 'substance-free phonology', especially Mark Hale and Charles Reiss.

paragraph_text: In 1976 John Goldsmith introduced autosegmental phonology. Phonological phenomena are no longer seen as operating on one linear sequence of segments, called phonemes or feature combinations, but rather as involving some parallel sequences of features which reside on multiple tiers. Autosegmental phonology later evolved into feature geometry, which became the standard theory of representation for theories of the organization of phonology as different as lexical phonology and optimality theory.

paragraph_text: Unlike most languages that use alphabets to indicate the pronunciation, Chinese characters have developed from logograms that do not always give hints to its pronunciation. Although the written characters remained relatively consistent for the last two thousand years, the pronunciation and grammar in different regions has developed to an extent that the varieties of the spoken language are often mutually unintelligible. As a series of migration to the south throughout the history, the regional languages of the south, including Xiang, Wu, Gan, Min, Yue (Cantonese), and Hakka often show traces of Old Chinese or Middle Chinese. From the Ming dynasty onward, Beijing has been the capital of China and the dialect spoken in Beijing has had the most prestige among other varieties. With the founding of the Republic of China, Standard Mandarin was designated as the official language, based on the spoken language of Beijing. Since then, other spoken varieties are regarded as fangyan (dialects). Cantonese is still the most commonly used language in Hong Kong, Macau and among some overseas Chinese communities, whereas Southern Min has been accepted in Taiwan as an important local language along with Mandarin.

paragraph_text: The Beijing dialect (simplified Chinese: 北京话; traditional Chinese: 北京話; pinyin: Běijīnghuà), also known as Pekingese, is the prestige dialect of Mandarin spoken in the urban area of Beijing, China. It is the phonological basis of Standard Chinese, which is the official language in the People's Republic of China and Republic of China and one of the official languages in Singapore.

paragraph_text: Government phonology, which originated in the early 1980s as an attempt to unify theoretical notions of syntactic and phonological structures, is based on the notion that all languages necessarily follow a small set of principles and vary according to their selection of certain binary parameters. That is, all languages' phonological structures are essentially the same, but there is restricted variation that accounts for differences in surface realizations. Principles are held to be inviolable, though parameters may sometimes come into conflict. Prominent figures in this field include Jonathan Kaye, Jean Lowenstamm, Jean-Roger Vergnaud, Monik Charette, and John Harris.

paragraph_text: In 1980, a vocational school for deaf adolescents was opened in the area of Managua called Villa Libertad. By 1983, there were over 400 deaf students enrolled in the two schools. Initially, the language program emphasized spoken Spanish and lipreading, and the use of signs by teachers was limited to fingerspelling (using simple signs to sign the alphabet). The program achieved little success, with most students failing to grasp the concept of Spanish words.

paragraph_text: The most widely spoken family of languages in southern Europe are the Romance languages, the heirs of Latin, which have spread from the Italian peninsula, and are emblematic of Southwestern Europe. (See the Latin Arch.) By far the most common romance languages in Southern Europe are: Italian, which is spoken by over 50 million people in Italy, San Marino, and the Vatican; and Spanish, which is spoken by over 40 million people in Spain and Gibraltar. Other common romance languages include: Romanian, which is spoken in Romania and Moldova; Portuguese, which is spoken in Portugal; Catalan, which is spoken in eastern Spain; and Galician, which is spoken in northwestern Spain.

paragraph_text: The word phonology comes from the Greek φωνή, phōnḗ, "voice, sound," and the suffix -logy (which is from Greek λόγος, lógos, "word, speech, subject of discussion"). Definitions of the term vary. Nikolai Trubetzkoy in Grundzüge der Phonologie (1939) defines phonology as "the study of sound pertaining to the system of language," as opposed to phonetics, which is "the study of sound pertaining to the act of speech" (the distinction between language and speech being basically Saussure's distinction between langue and parole). More recently, Lass (1998) writes that phonology refers broadly to the subdiscipline of linguistics concerned with the sounds of language, while in more narrow terms, "phonology proper is concerned with the function, behavior and organization of sounds as linguistic items." According to Clark et al. (2007), it means the systematic use of sound to encode meaning in any spoken human language, or the field of linguistics studying this use.

paragraph_text: Natural phonology is a theory based on the publications of its proponent David Stampe in 1969 and (more explicitly) in 1979. In this view, phonology is based on a set of universal phonological processes that interact with one another; which ones are active and which are suppressed is language-specific. Rather than acting on segments, phonological processes act on distinctive features within prosodic groups. Prosodic groups can be as small as a part of a syllable or as large as an entire utterance. Phonological processes are unordered with respect to each other and apply simultaneously (though the output of one process may be the input to another). The second most prominent natural phonologist is Patricia Donegan (Stampe's wife); there are many natural phonologists in Europe, and a few in the U.S., such as Geoffrey Nathan. The principles of natural phonology were extended to morphology by Wolfgang U. Dressler, who founded natural morphology.

paragraph_text: Colombian Spanish (Spanish: español colombiano) is a grouping of the varieties of Spanish spoken in Colombia. The term is of more geographical than linguistic relevance, since the dialects spoken in the various regions of Colombia are quite diverse. The speech of coastal areas tends to exhibit phonological innovations typical of Caribbean Spanish, while highland varieties have been historically more conservative. The Caro and Cuervo Institute in Bogotá is the main institution in Colombia promoting the scholarly study of the language and literature of both Colombia and Spanish America generally. The educated speech of Bogotá, a generally conservative variety of Spanish, holds high popular prestige among Spanish - speakers throughout the Americas.

paragraph_text: The numero sign or numero symbol, No (also represented as No, No, No. or no. (US English), or No or no (UK English) plural Nos. or nos. (US English) or Nos or nos UK English), is a typographic abbreviation of the word number (s) indicating ordinal numeration, especially in names and titles. For example, with the numero sign, the written long - form of the address ``Number 22 Acacia Avenue ''is shortened to`` No 22 Acacia Avenue'', yet both forms are spoken long.

paragraph_text: Prince Nikolai Sergeyevich Trubetzkoy (; Moscow, April 16, 1890 – Vienna, June 25, 1938) was a Russian linguist and historian whose teachings formed a nucleus of the Prague School of structural linguistics. He is widely considered to be the founder of morphophonology. He was also associated with the Russian Eurasianists.

paragraph_text: Phonology is often distinguished from phonetics. While phonetics concerns the physical production, acoustic transmission and perception of the sounds of speech, phonology describes the way sounds function within a given language or across languages to encode meaning. For many linguists, phonetics belongs to descriptive linguistics, and phonology to theoretical linguistics, although establishing the phonological system of a language is necessarily an application of theoretical principles to analysis of phonetic evidence. Note that this distinction was not always made, particularly before the development of the modern concept of the phoneme in the mid 20th century. Some subfields of modern phonology have a crossover with phonetics in descriptive disciplines such as psycholinguistics and speech perception, resulting in specific areas like articulatory phonology or laboratory phonology.

paragraph_text: An influential school of phonology in the interwar period was the Prague school. One of its leading members was Prince Nikolai Trubetzkoy, whose Grundzüge der Phonologie (Principles of Phonology), published posthumously in 1939, is among the most important works in the field from this period. Directly influenced by Baudouin de Courtenay, Trubetzkoy is considered the founder of morphophonology, although this concept had also been recognized by de Courtenay. Trubetzkoy also developed the concept of the archiphoneme. Another important figure in the Prague school was Roman Jakobson, who was one of the most prominent linguists of the 20th century.

Question: What was the primary language of the man who, in 1939, defined phonology?
