Devanagari is an Indic script used in the northern Indian subcontinent. Also simply called Nāgari, it is a left-to-right abugida, based on the ancient Brāhmi script. It is one of the official scripts of the Republic of India and Nepal. It was developed and in regular use by the 7th century CE and achieved its modern form by 1000 CE. The Devanāgari script, composed of 48 primary characters, including 14 vowels and 34 consonants, is the fourth most widely adopted writing system in the world, being used for over 120 languages.
The Indo-European languages are a language family native to the overwhelming majority of Europe, the Iranian plateau, and the northern Indian subcontinent. Some European languages of this family—English, French, Portuguese, Russian, Dutch, and Spanish—have expanded through colonialism in the modern period and are now spoken across several continents. The Indo-European family is divided into several branches or sub-families, of which there are eight groups with languages still alive today: Albanian, Armenian, Balto-Slavic, Celtic, Germanic, Hellenic, Indo-Iranian, and Italic; another nine subdivisions are now extinct.
Sanskrit is a classical language belonging to the Indo-Aryan branch of the Indo-European languages. It arose in South Asia after its predecessor languages had diffused there from the northwest in the late Bronze Age. Sanskrit is the sacred language of Hinduism, the language of classical Hindu philosophy, and of historical texts of Buddhism and Jainism. It was a link language in ancient and medieval South Asia, and upon transmission of Hindu and Buddhist culture to Southeast Asia, East Asia and Central Asia in the early medieval era, it became a language of religion and high culture, and of the political elites in some of these regions. As a result, Sanskrit had a lasting effect on the languages of South Asia, Southeast Asia and East Asia, especially in their formal and learned vocabularies.
The Indo-Aryan languages are a branch of the Indo-Iranian languages in the Indo-European language family. As of the early 21st century, they have more than 800 million speakers, primarily concentrated in India, Pakistan, Sri Lanka, Bangladesh, Nepal and Maldives. Moreover, apart from the Indian subcontinent, large immigrant and expatriate Indo-Aryan–speaking communities live in Northwestern Europe, Western Asia, North America, the Caribbean, Southeast Africa, Polynesia and Australia, along with several million speakers of Romani languages primarily concentrated in Southeastern Europe. There are over 200 known Indo-Aryan languages.
Avestan is an umbrella term for two Old Iranian languages, Old Avestan and Younger Avestan. They are known only from their conjoined use as the scriptural language of Zoroastrianism; the Avesta serves as their namesake. Both are early Eastern Iranian languages within the Indo-Iranian language branch of the Indo-European language family. Its immediate ancestor was the Proto-Iranian language, a sister language to the Proto-Indo-Aryan language, with both having developed from the earlier Proto-Indo-Iranian language; as such, Old Avestan is quite close in both grammar and lexicon to Vedic Sanskrit, the oldest preserved Indo-Aryan language.
Vedic Sanskrit, also simply referred as the Vedic language, is an ancient language of the Indo-Aryan subgroup of the Indo-European language family. It is attested in the Vedas and related literature compiled over the period of the mid-2nd to mid-1st millennium BCE. It is orally preserved, predating the advent of writing by several centuries.
Gāndhārī is an Indo-Aryan Prakrit language found mainly in texts dated between the 3rd century BCE and 4th century CE in the region of Gandhāra, located in present day Pakistan's Potohar region. The language was heavily used by the former Buddhist cultures of Central Asia and has been found as far away as eastern China, in inscriptions at Luoyang and Anyang.
The ruki sound law, also known as the ruki rule or iurk rule, is a historical sound change that took place in the satem branches of the Indo-European language family, namely in Balto-Slavic, Armenian, and Indo-Iranian. According to this sound law, an original *s changed to *š after the consonants *r, *k, *g, *gʰ and the semi-vowels *w (*u̯) and *y (*i̯), as well as the syllabic allophones *r̥, *i, and *u:
Indo-Iranian peoples, also known as Indo-Iranic peoples by scholars, or as Arya or Aryans from their self-designation, were a group of Indo-European speaking peoples who brought the Indo-Iranian languages, a major branch of the Indo-European language family, to major parts of Eurasia in waves from the first part of the 2nd millennium BC onwards. They eventually branched out into Iranian peoples and Indo-Aryan peoples.
The Iranian languages, also called the Iranic languages, are a branch of the Indo-Iranian languages in the Indo-European language family that are spoken natively by the Iranian peoples, predominantly in the Iranian Plateau.
As the Proto-Indo-European language (PIE) broke up, its sound system diverged as well, as evidenced in various sound laws associated with the daughter Indo-European languages.
Bartholomae's law is an early Indo-European (PIE) sound law affecting the Indo-Iranian family. It states that in a cluster of two or more obstruents, any one of which is a voiced aspirated stop anywhere in the sequence, the whole cluster becomes voiced and aspirated. Thus to the PIE root *bʰewdʰ- "learn, become aware of" the participle *bʰudʰ-to- "enlightened" loses the aspiration of the first stop and with the application of Bartholomae's law and regular vowel changes gives Sanskrit buddha "enlightened".
Proto-Indo-Iranian, also called Proto-Indo-Iranic or Proto-Aryan, is the reconstructed proto-language of the Indo-Iranian branch of Indo-European. Its speakers, the hypothetical Proto-Indo-Iranians, are assumed to have lived in the late 3rd millennium BC, and are often connected with the Sintashta culture of the Eurasian Steppe and the early Andronovo archaeological horizon.
Brugmann's law, named for Karl Brugmann, is a sound law stating that in the Indo-Iranian languages, the earlier Proto-Indo-European *o normally became *a in Proto-Indo-Iranian but *ā in open syllables if it was followed by one consonant and another vowel. For example, the Proto-Indo-European noun for 'wood' was *dόru, which in Vedic became dāru. Everywhere else, the outcome was *a, the same as the reflexes of PIE *e and *a.
The Middle Indo-Aryan languages are a historical group of languages of the Indo-Aryan family. They are the descendants of Old Indo-Aryan and the predecessors of the modern Indo-Aryan languages, such as Hindustani (Hindi-Urdu), Bengali and Punjabi.
Proto-Iranian or Proto-Iranic is the reconstructed proto-language of the Iranian languages branch of Indo-European language family and thus the ancestor of the Iranian languages such as Persian, Pashto, Sogdian, Zazaki, Ossetian, Mazandarani, Kurdish, Talysh and others. Its speakers, the hypothetical Proto-Iranians, are assumed to have lived in the 2nd millennium BC and are usually connected with the Andronovo archaeological horizon.
Vedic Sanskrit has a number of linguistic features which are alien to most other Indo-European languages. Prominent examples include: phonologically, the introduction of retroflexes, which alternate with dentals, and morphologically, the formation of gerunds. Some philologists attribute such features, as well as the presence of non-Indo-European vocabulary, to a local substratum of languages encountered by Indo-Aryan peoples in Central Asia (Bactria-Marghiana) and within the Indian subcontinent during Indo-Aryan migrations, including the Dravidian languages.
Aryan or Arya is a term originally used as an ethnocultural self-designation by Indo-Iranians in ancient times, in contrast to the nearby outsiders known as 'non-Aryan'. In Ancient India, the term ā́rya was used by the Indo-Aryan speakers of the Vedic period as an endonym (self-designation) and in reference to a region known as Āryāvarta, where the Indo-Aryan culture emerged. In the Avesta scriptures, ancient Iranian peoples similarly used the term airya to designate themselves as an ethnic group, and in reference to their mythical homeland, Airyanǝm Vaēǰō. The stem also forms the etymological source of place names such as Alania and Iran.
Ashokan Prakrit is the Middle Indo-Aryan dialect continuum used in the Edicts of Ashoka, attributed to Emperor Ashoka of the Mauryan Empire who reigned 268 BCE to 232 BCE. The Edicts are inscriptions on monumental pillars and rocks throughout the Indian subcontinent that cover Ashoka's conversion to Buddhism and espouse Buddhist principles.
The Inner–Outer hypothesis of the subclassification of the Indo-Aryan language family argues for a division of the family into two groups, an Inner core and an Outer periphery, evidenced by shared traits of the languages falling into one of the two groups. Proponents of the theory generally believe the distinction to be the result of gradual migrations of Indo-Aryan speakers into the Indian subcontinent, with the inner languages representing a second wave of migration speaking a different dialect of Old Indo-Aryan, overtaking the first-wave speakers in the center and relegating them to the outer region.
