The term "Arabic" may refer with equal accuracy to either literary Arabic (fu?) or the many localized varieties of Arabic commonly called "colloquial Arabic". Arabs consider literary Arabic as the standard language and tend to view everything else as mere dialects. Literary Arabic translit: al-lu?atu l-arabiyyatu l-fu? "the most eloquent Arabic language"), refers both to the language of present-day media across North Africa and the Middle East and to the language of the Qur'an. (The expression media here includes most television and radio, and practically all written matter, including all books, newspapers, magazines, documents of every kind, and reading primers for small children.) "Colloquial" or "dialectal" Arabic refers to the many national or regional varieties derived from Classical Arabic, spoken daily across North Africa and the Middle East, which constitute the everyday spoken language. These sometimes differ enough to be mutually incomprehensible. These dialects are not typically written, although a certain amount of literature (particularly plays and poetry) exists in many of them. They are often used to varying degrees in informal spoken media, such as soap operas and talk shows. Literary Arabic or classical Arabic is the official language of all Arab countries and is the only form of Arabic taught in schools at all stages.

Hindi is the name given to an Indo-Aryan language, or a dialect continuum of languages, spoken in northern and central India (the "Hindi belt"), It is the national language of India. The native speakers of Hindi dialects between them account for 40% of the Indian population (1991 Indian census). Standard Hindi is one of the 22 official languages of India, and is used, along with English, for administration of the central government. Standard Hindi is a Sanskritized register derived from the khari boli dialect. Urdu is a different, Persianized, register of the same dialect. Taken together, these registers are historically also known as Hindustani. The word Hind? is of Persian origin and literally means "Indian", comprising Hind "India", and the adjectival suffix -?. The word was originally used by Muslims in north India to refer to any Indian language: for example the eleventh-century writer Ab? Rayh?n al-B?r?n? used it to refer to Sanskrit. By the 13th century, "Hindi", along with its variant forms "Hindavi" and "Hindui", had acquired a more specific meaning: the "linguistically mixed speech of Delhi, which came into wide use across north India and incorporated a component of Persian vocabulary". It was later used by members of the Mughal court to distinguish the local vernacular of the Delhi region where the court was located from Persian, which was the official language of the court. Evidence from the 17th century indicates that the language then called "Hindi" existed in two differing styles: among Muslims it was liable to contain a larger component of Persian-derived words and would be written down in a script derived from Persian, while among Hindus it used a vocabulary more influenced by Sanskrit and was written in Devanagari script. These styles eventually developed into modern Urdu and modern Hindi respectively. However the word "Urdu" was not used until around 1780: before then the word "Hindi" could be used for both purposes. The use of "Hindi" to designate what would now be called "Urdu" continued as late as the early twentieth century. Nowadays Hind? as taken to mean "Indian" is chiefly obsolete; it has come to specifically refer to the language(s) bearing that name.
