Derived from the Greek word διγλωσσία, which is defined as bilinguality or bilingualism, diglossia is a linguistic phenomenon in which a language has two varieties often labeled as a high variety (“H”) and a low variety (“L”).

The term was coined in its specialized meaning by Emmanuel Rhoides in 1885 and was subsequently adapted into other languages, like French as “diglossie” and Spanish as “diglosia”, to denote this side-by-side linguistic coexistence.

What constitutes a diglossic language?

The term was first used to describe the situation in which one community strictly uses the high variety (“H”) in formal situations, such as literature and mass media, and the low variety (“L”) in ordinary conversations. This means that the two varieties are closely-related and belong inherently to the same language. Historically, the high variety (“H”) was used at an earlier stage of the language, such as the case of Classical Latin, and the low variety (“L”) diverged as a continuum from colloquial speech, such as the case of Vulgar Latin. However, the term was later expanded to include communities in which the high variety (“H”) and the low variety (“L”) were unrelated languages. An example of this is Jamaican Creole, which is regarded as the low variety (“L”) and Standard English, which is regarded as the high variety (“H”) in Jamaica. Another example is Wolof, which is the lingua franca for everyday conversations (“L”), and French, which is reserved for formal interactions (“H”) in Senegal. These two notions were later given the names “exoglossia” for the high variety (“H”) and “endoglossia” for the low variety (“L”).Diglossia

What are the situations in which the high variety and the low variety are used?

In diglossic communities, the low variety (“L”) is the language of home, friends and informal interactions. The high variety (“H”) is, however, held in high esteem and rules the sphere of politics, education and translation. Most speakers of diglossic languages will agree that the low variety (“L”) has no grammatical rules or an established writing system. This makes its translation socially inappropriate because it’s a variety used in the wrong situation. On the other hand, the high variety (“H”) has no native speakers and is typically characterized by more complex grammatical rules. If we look at the situation from this perspective, does this mean it’s impossible to hire native translators for diglossic languages such as Arabic, German and Chinese?

In the case of same-language diglossia, the low variety (“L”) is highly subordinated by the high variety (“H”). Technically speaking, the low variety (“L”) has the tendency to generate words from the high variety (“H”) in most cases. This makes the two varieties mutually intelligible to some extent. In the case of Arabic, most of the low variety (“L”) terms are derived from the high variety (“H”) while denoting a change in the pronunciation. One example is the pronunciation of the “g” in “generous” as the “g” in “garden”, which is highly noticeable in Egyptian Arabic. Despite this divergence, the high variety (“H”) is widely understood by Arabic speakers although not used in vernacular speech.

What are the side effects diglossia has on translation?

In translation studies, diglossia can cause linguistic weakness in students. This is because they spend the first few years of their lives learning the vernacular type of the language and the next few years learning the high prestige form. Some other complications are the presence of a sort of confusion between the high variety (“H”) and the low variety (“L”). The students are equally exposed to the vernacular speech pattern and the high prestige speech pattern, which can lead the two varieties to overlap.

As mentioned before, the use of the low variety (“L”) in formal situations is, in many cases, frowned upon. This weakness can be treated as an ordinary linguistic weakness and remedied through exposure to the high prestige form of the language. The goal is to create a further division between these two varieties in order to use each one of them for the intended purpose. As it is defined in the Greek language, diglossia is, after all, another form of bilingualism.
