Diglossia in the context of Sinhalese language

Modern Greek (endonym: Νέα Ελληνικά, Néa Elliniká [ˈne.a eliniˈka] or Κοινή Νεοελληνική Γλώσσα, Kiní Neoellinikí Glóssa), generally referred to by speakers simply as Greek (Ελληνικά, Elliniká), refers collectively to the dialects of the Greek language spoken in the modern era, including the official standardized form of the language sometimes referred to as Standard Modern Greek. The end of the Medieval Greek period and the beginning of Modern Greek is often symbolically assigned to the fall of the Byzantine Empire in 1453, even though that date marks no clear linguistic boundary and many characteristic features of the modern language arose centuries earlier, having begun around the fourth century AD.

During most of the Modern Greek period, the language existed in a situation of diglossia, with regional spoken dialects existing side by side with learned, more archaic written forms, as with the vernacular and learned varieties (Dimotiki and Katharevousa) that co-existed in Greece throughout much of the 19th and 20th centuries.

Literary language is the register of a language used when writing in a formal, academic, or particularly polite tone; when speaking or writing in such a tone, it can also be known as formal language. It may be the standardized variety of a language. It can sometimes differ noticeably from the various spoken lects, but the difference between literary and non-literary forms is greater in some languages than in others. If there is a strong divergence between a written form and the spoken vernacular, the language is said to exhibit diglossia.

The understanding of the term differs from one linguistic tradition to another and is dependent on the terminological conventions adopted.

The linguistic varieties of Modern Greek can be classified along two principal dimensions. First, there is a long tradition of sociolectal variation between the natural, popular spoken language on the one hand and archaizing, learned written forms on the other. Second, there is regional variation between dialects. The competition between the popular and the learned registers (see Diglossia) culminated in the struggle between Dimotiki and Katharevousa during the 19th and 20th centuries. As for regional dialects, variation within the bulk of dialects of present-day Greece is not particularly strong, except for a number of outlying, highly divergent dialects spoken by isolated communities.

Demotic Greek (Greek: Δημοτική Γλώσσα, Dimotikí Glóssa, [ðimotiˈci ˈɣlo.sa], lit. 'language of the people') is the standard spoken language of Greece in modern times and, since the resolution of the Greek language question in 1976, the official language of Greece. "Demotic Greek" (with a capital D) contrasts with the conservative Katharevousa, which was used in formal settings, during the same period. In that context, Demotic Greek describes the specific non-standardized vernacular forms of Greek used by the vast majority of Greeks during the 19th and 20th centuries.

As is typical of diglossic situations, Katharevousa and Demotic complemented and influenced each other. Over time, Demotic became standardized. In 1976, it was made the official language of Greece. It continued to evolve and is now called Standard Modern Greek. The term "demotic Greek" (with a minuscule d) also refers to any variety of the Greek language which has evolved naturally from Ancient Greek and is popularly spoken.

Written Chinese is a writing system that uses Chinese characters and other symbols to represent the Chinese languages. Chinese characters do not directly represent pronunciation, unlike letters in an alphabet or syllabograms in a syllabary. Rather, the writing system is morphosyllabic: characters are one spoken syllable in length, but generally correspond to morphemes in the language, which may either be independent words, or part of a polysyllabic word. Most characters are constructed from smaller components that may reflect the character's meaning or pronunciation. Literacy requires the memorization of thousands of characters; college-educated Chinese speakers know approximately 4,000. This has led in part to the adoption of complementary transliteration systems (generally Pinyin) as a means of representing the pronunciation of Chinese.

Chinese writing is first attested during the late Shang dynasty (c. 1250 – c. 1050 BCE), but the process of creating characters is thought to have begun centuries earlier during the Late Neolithic and early Bronze Age (c. 2500–2000 BCE). After a period of variation and evolution, Chinese characters were standardized under the Qin dynasty (221–206 BCE). Over the millennia, these characters have evolved into well-developed styles of Chinese calligraphy. As the varieties of Chinese diverged, a situation of diglossia developed, with speakers of mutually unintelligible varieties able to communicate through writing using Literary Chinese. In the early 20th century, Literary Chinese was replaced in large part with written vernacular Chinese, largely corresponding to Standard Chinese, a form based on the Beijing dialect of Mandarin. Although most other varieties of Chinese are not written, there are traditions of written Cantonese, written Shanghainese and written Hokkien, among others.

A classical language is any language with an independent literary tradition and a large body of ancient written literature.

Classical languages are usually extinct languages. Those that are still in use today tend to show highly diglossic characteristics in areas where they are used, as the difference between spoken and written language has widened over time.

Byzantine literature is the Greek literature of the Middle Ages, whether written in the Byzantine Empire or outside its borders. It was marked by a linguistic diglossy; two distinct forms of Byzantine Greek were used, a scholarly dialect based on Attic Greek, and a vernacular based on Koine Greek. Most scholars consider 'literature' to include all medieval Greek texts, but some define it with specific constraints. Byzantine literature is the successor to Ancient Greek literature and forms the basis of Modern Greek literature, although it overlaps with both periods.

The tradition saw the competing influences of Hellenism, Christianity, and earlier in the empire's history, Paganism. There was a general flourishing of gnomai, hagiography, sermons, and particularly historiography, which became less individual-focused. Poetry was often limited to musical hymnal forms, or the more niche epigram tradition, while ancient dramas and epics became obsolete. The influential romantic epic Digenes Akritas is a major exception.

Varieties of Arabic (or dialects or vernaculars) are the linguistic systems that Arabic speakers speak natively. Arabic is a Semitic language within the Afroasiatic family that originated in the Arabian Peninsula. There are considerable variations from region to region, with degrees of mutual intelligibility that are often related to geographical distance and some that are mutually unintelligible. Many aspects of the variability attested to in these modern variants can be found in the ancient Arabic dialects in the peninsula. Likewise, many of the features that characterize (or distinguish) the various modern variants can be attributed to the original settler dialects as well as local native languages and dialects. Some organizations, such as SIL International, consider these approximately 30 different varieties to be separate languages, while others, such as the Library of Congress, consider them all to be dialects of Arabic.

In terms of sociolinguistics, a major distinction exists between the formal standardized language, found mostly in writing or in prepared speech, and the widely diverging vernaculars, used for everyday speaking situations. The latter vary from country to country, from speaker to speaker (according to personal preferences, education and culture), and depending on the topic and situation. In other words, Arabic in its natural environment usually occurs in a situation of diglossia, which means that its native speakers often learn and use two linguistic forms substantially different from each other, the Modern Standard Arabic (MSA) as the official language and a local colloquial variety (called العامية, al-ʿāmmiyya in many Arab countries, meaning "slang" or "colloquial"; or called الدارجة, ad-dārija, meaning "common or everyday language" in the Maghreb), in different aspects of their lives.

Maltese (Maltese: Malti, also L-Ilsien Malti or Lingwa Maltija) is a Central Semitic language derived from late medieval Sicilian Arabic with Romance superstrata. It is the only Semitic language written in the Latin script. It is spoken by the Maltese people and is a national language of Malta, and is the only official Semitic and Afroasiatic language of the European Union. According to John L. Hayes, it descended from a North African dialect of Colloquial Arabic which was introduced to Malta when the Aghlabids captured it in 869/870 CE. It is also said to have descended from Siculo-Arabic, which developed as a Maghrebi Arabic dialect in the Emirate of Sicily between 831 and 1091. As a result of the Norman invasion of Malta and the subsequent re-Christianisation of the islands, Maltese evolved independently of Classical Arabic in a gradual process of Latinisation. It is therefore exceptional as a variety of historical Arabic that has no diglossic relationship with Classical or Modern Standard Arabic. Maltese is thus classified separately from the 30 varieties constituting the modern Arabic macrolanguage. Maltese is also distinguished from Arabic and other Semitic languages since its morphology has been deeply influenced by Romance languages, namely Italian and Sicilian.

The original Arabic base comprises around one-third of the Maltese vocabulary, especially words that denote basic ideas and the function words, but about half of the vocabulary is derived from standard Italian and Sicilian; and English words make up between 6% and 20% of the vocabulary. A 2016 study shows that, in terms of basic everyday language, speakers of Maltese are able to understand less than a third of what is said to them in Tunisian Arabic and Libyan Arabic, which are Maghrebi Arabic dialects related to Siculo-Arabic, whereas speakers of Tunisian Arabic and Libyan Arabic are able to understand about 40% of what is said to them in Maltese. This reported level of asymmetric intelligibility is considerably lower than the mutual intelligibility found between mainstream varieties of Arabic.

Catalan (català) is a Western Romance language. It is the official language of Andorra and the official language of three autonomous communities in eastern Spain: Catalonia, the Balearic Islands and the Valencian Community, where it is called Valencian (valencià). It has semi-official status in the Italian municipality of Alghero, and it is spoken in the Pyrénées-Orientales department of France and in two further areas in eastern Spain: the eastern strip of Aragon and the Carche area in the Region of Murcia. The Catalan-speaking territories are often called the Països Catalans or "Catalan Countries".

The language evolved from Vulgar Latin in the Middle Ages around the eastern Pyrenees. It became the language of the Principality of Catalonia and the kingdoms of Valencia and Mallorca, being present throughout the Mediterranean as the main language of the Crown of Aragon. It was replaced by Spanish as a language of government and literature in the 1700s, but nineteenth century Spain saw a Catalan literary revival, culminating in the early 1900s. With the end of Franco dictatorship (1975) and its repressive measures against the language, Catalan entered a relatively successful process of re-normalization between the 1980s and the 2000s. However, during the 2010s, it experienced signs of decline in social use, diglossia and the re-growth of discrimination cases.

The Greek language question (Greek: το γλωσσικό ζήτημα, to glossikó zítima) was a dispute about whether the vernacular of the Greek people (Demotic Greek) or a cultivated literary language based on Ancient Greek (Katharevousa) should be the prevailing language of the people and government of Greece. It was a highly controversial topic in the 19th and 20th centuries, and was finally resolved in 1976 when Demotic was made the official language. The language phenomenon in question, which also occurs elsewhere in the world, is called diglossia.

The Brunei Malay, also called Bruneian Malay (Malay: Bahasa Melayu Brunei; Jawi: بهاس ملايو بروني‎), is the most widely spoken language in Brunei Darussalam and a lingua franca in some parts of Sarawak and Sabah, such as Labuan, Limbang, Lawas, Sipitang, Beaufort, Kuala Penyu and Papar. Though Standard Malay is promoted as the official national language of Brunei, Brunei Malay is socially dominant and it is currently replacing the minority languages of Brunei, including the Dusun and Tutong languages, existing in a diglossic speech, wherein Brunei Malay is commonly used for daily communication, coexisting with the aforementioned regional languages and Malay creoles, and standard Malay used in formal speech; code switching between standard Malay and Brunei Malay is spoken in informal speech as a lingua franca between Malay creoles and regional languages. It is quite similar to Standard Malay to the point of being almost mutually intelligible with it, being about 84% cognate with standard Malay. Standard Malay is usually spoken with Brunei pronunciation.

Sinhala (/ˈsɪnhələ, ˈsɪŋələ/ SIN-hə-lə, SING-ə-lə; Sinhala: සිංහල, siṁhala, [ˈsiŋɦələ]), sometimes called Sinhalese (/ˌsɪn(h)əˈliːz, ˌsɪŋ(ɡ)əˈliːz/ SIN-(h)ə-LEEZ, SING-(g)ə-LEEZ), is an Indo-Aryan language primarily spoken by the Sinhalese people of Sri Lanka, who make up the largest ethnic group on the island, numbering about 16 million. It is also the first language of about 2 million other Sri Lankans, as of 2001. It is written in the Sinhalese script, a Brahmic script closely related to the Grantha script of South India. The language has two main varieties, written and spoken, and is a notable example of the linguistic phenomenon known as diglossia.

Sinhala is one of the official and national languages of Sri Lanka. Along with Pali, it played a major role in the development of Theravada Buddhist literature.
