Question: What is the coat of arms of the birthplace of the person who defined phonology in 1939 based on?

full_context: Document 1: Phonology: The Polish scholar Jan Baudouin de Courtenay (together with his former student Mikołaj Kruszewski) introduced the concept of the phoneme in 1876, and his work, though often unacknowledged, is considered to be the starting point of modern phonology. He also worked on the theory of phonetic alternations (what is now called allophony and morphophonology), and had a significant influence on the work of Ferdinand de Saussure.
Document 2: Coat of arms of Moscow: The coat of arms of Moscow depicts a horseman with a spear in his hand slaying a basilisk and is identified with Saint George and the Dragon. The heraldic emblem of Moscow has been an integral part of the coat of arms of Russia since the 16th century.
Document 3: Phonology: 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.
Document 4: Alexander Potebnja: Alexander Potebnja (; ) was a Russian Imperial philosopher and linguist, who was a professor of linguistics at the University of Kharkov. He is well known as a specialist in the evolution of Russian phonetics. He also translated part of Homer's Odyssey into Ukrainian. He constructed a theory of language and consciousness that later influenced the thinking of his countryman the Psychologist Lev Vygotsky. His main work was "Language and Thought" ("mysl' i jazyk") (1862). he was a corresponding member of the St. Petersburg Academy of Sciences, the foremost academic institution in the Russian Empire.
Document 5: Moscow: Moscow is situated on the Moskva River in the Central Federal District of European Russia, making it Europe's most populated inland city. The city is well known for its architecture, particularly its historic buildings such as Saint Basil's Cathedral with its brightly coloured domes. With over 40 percent of its territory covered by greenery, it is one of the greenest capitals and major cities in Europe and the world, having the largest forest in an urban area within its borders -- more than any other major city -- even before its expansion in 2012. The city has served as the capital of a progression of states, from the medieval Grand Duchy of Moscow and the subsequent Tsardom of Russia to the Russian Empire to the Soviet Union and the contemporary Russian Federation.
Document 6: Nikolai Trubetzkoy: 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.
Document 7: Phonology: The history of phonology may be traced back to the Ashtadhyayi, the Sanskrit grammar composed by Pāṇini in the 4th century BC. In particular the Shiva Sutras, an auxiliary text to the Ashtadhyayi, introduces what can be considered a list of the phonemes of the Sanskrit language, with a notational system for them that is used throughout the main text, which deals with matters of morphology, syntax and semantics.
Document 8: Moscow Kremlin: The Moscow Kremlin (Russian: Моско́вский Кремль, tr. Moskovskiy Kreml, IPA: (mɐˈskofskjɪj krjemlj)), usually referred to as the Kremlin, is a fortified complex at the heart of Moscow, overlooking the Moskva River to the south, Saint Basil's Cathedral and Red Square to the east, and the Alexander Garden to the west. It is the best known of the kremlins (Russian citadels) and includes five palaces, four cathedrals, and the enclosing Kremlin Wall with Kremlin towers. Also within this complex is the Grand Kremlin Palace that was formerly the tsar's Moscow residence. The complex serves as the official residence of the President of the Russian Federation.
Document 9: Flag of Saint Petersburg: The flag of Saint Petersburg, in the Russian Federation, is a red field charged in the centre with the arms of the city, which consists of two silver anchors (a sea anchor, and a river anchor), and a gold scepter.
Document 10: Phonology: In 1968 Noam Chomsky and Morris Halle published The Sound Pattern of English (SPE), the basis for generative phonology. In this view, phonological representations are sequences of segments made up of distinctive features. These features were an expansion of earlier work by Roman Jakobson, Gunnar Fant, and Morris Halle. The features describe aspects of articulation and perception, are from a universally fixed set, and have the binary values + or −. There are at least two levels of representation: underlying representation and surface phonetic representation. Ordered phonological rules govern how underlying representation is transformed into the actual pronunciation (the so-called surface form). An important consequence of the influence SPE had on phonological theory was the downplaying of the syllable and the emphasis on segments. Furthermore, the generativists folded morphophonology into phonology, which both solved and created problems.
Document 11: Moscow: Moscow (/ ˈmɒskoʊ / or / ˈmɒskaʊ /; Russian: Москва́, tr. Moskva, IPA: (mɐˈskva) (listen)) is the capital and most populous city of Russia, with 12.2 million residents within the city limits and 17.1 million within the urban area. Moscow has the status of a Russian federal city.
Document 12: Zdzisław Stieber: Stieber also produced works on the history and development of Polish (1934), Czech (1957), and Slavic in general (1969). Stieber held teaching appointments in Kraków, Lviv, Łódź, and Warsaw. His work in Polish and Slavic philology had a particularly strong influence on the introduction of the structural method in the teaching of phonology at the University of Łódź.
Document 13: Phonology: 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.
Document 14: Phonology: 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.
Document 15: Phonology: 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.
