Brahmi script in the context of Southern Brahmic

An abugida (/ˌɑːbuːˈɡiːdə, ˌæb-/ ; from Geʽez: አቡጊዳ, 'äbugīda)—sometimes also called an alphasyllabary, neosyllabary, or pseudo-alphabet—is a segmental writing system in which consonant–vowel sequences are written as units; each unit is based on a consonant letter, and vowel notation is secondary, like a diacritical mark. This contrasts with a full alphabet, in which vowels have status equal to consonants, and with an abjad, in which vowel marking is absent, partial, or optional. In less formal contexts, all three types of script may be termed "alphabets". The terms also contrast them with a syllabary, in which a single symbol denotes the combination of a consonant and a vowel.

Related concepts were introduced independently in 1948 by James Germain Février (using the term néosyllabisme) and David Diringer (using the term semisyllabary), and in 1959 by Fred Householder (introducing the term pseudo-alphabet). The Ethiopic term "abugida" was chosen as a designation for the concept in 1990 by Peter T. Daniels. Faber suggested "segmentally coded syllabically linear phonographic script"; William O. Bright used the term alphasyllabary; and Gnanadesikan and Rimzhim, Katz, & Fowler suggested aksara or āksharik.

The Brahmic scripts, also known as Indic scripts, are a family of abugida writing systems. They are descended from the Brahmi script of ancient India and are used by various languages in several language families in South, East and Southeast Asia: Indo-Aryan, Dravidian, Tibeto-Burman, Mongolic, Austroasiatic, Austronesian, and Tai. They were also the source of the dictionary order (gojūon) of Japanese kana.

The Edicts of Ashoka are a collection of more than thirty inscriptions on the Pillars of Ashoka, as well as boulders and cave walls, attributed to Emperor Ashoka of the Maurya Empire who ruled most of the Indian subcontinent from 268 BCE to 232 BCE. These inscriptions were dispersed throughout the areas of modern-day India, Bangladesh, Nepal, Afghanistan and Pakistan, and provide the first tangible evidence of Buddhism. The Edicts are the earliest written and datable texts from India, and, since they were inscribed on stone, we have the added benefit of having them exactly as they were originally inscribed. Earlier texts, such as the Vedic texts, were all composed and handed down orally until later dates.

Ashoka used the expression Dhaṃma Lipi (Prakrit in the Brahmi script: 𑀥𑀁𑀫𑀮𑀺𑀧𑀺, "Inscriptions of the Dharma") to describe his own Edicts. The edicts describe in detail Ashoka's policy on dhamma, an earnest attempt to solve some of the problems that a complex society faced. According to the edicts, the extent of his promotion of dhamma during this period reached as far as the Greeks in the Mediterranean region. While the inscriptions mention the conversion of Ashoka to Buddhism, the dhamma that he promotes is largely ecumenical and non-sectarian in nature. As historian Romila Thapar relates:

Vasudeva II (Middle Brahmi script: Bā-zo-de-o Sanskritzied to "Vasudeva") was a Kushan emperor who ruled c. 275–300. He was probably the successor of Kanishka III and may have been succeeded by an emperor named Shaka Kushan.

Vasudeva II probably only was a local ruler in the area of Taxila, in western Punjab, under the suzerainty of the Gupta Empire.

Sutra (Sanskrit: सूत्र, romanized: sūtra, lit. 'formula') in Indian literary traditions refers to an aphorism or a collection of aphorisms in the form of a manual or, more broadly, a condensed manual or text. Sutras are a genre of ancient and medieval Indian texts found in Hinduism, Buddhism and Jainism.

In Hinduism, sutras are a distinct type of literary composition, a compilation of short aphoristic statements. Each sutra is any short rule, like a theorem distilled into few words or syllables, around which teachings of ritual, philosophy, grammar, or any field of knowledge can be woven. The oldest sutras of Hinduism are found in the Brahmana and Aranyaka layers of the Vedas. Every school of Hindu philosophy, Vedic guides for rites of passage, various fields of arts, law, and social ethics developed respective sutras, which help teach and transmit ideas from one generation to the next.

Simuka (Brahmi:𑀲𑀺𑀫𑀼𑀓, Si-mu-ka) was an ancient Indian king belonging to the Satavahana dynasty, which ruled the Deccan region. He is mentioned as the first king in a list of royals in a Satavahana inscription at Nanaghat. In the Puranas, the name of the first (Satavahana) king is variously spelt as Shivmukha, Sishuka, Sindhuka, Chhismaka, Shipraka, Srimukha, etc. These are believed to be corrupted spellings of "Simuka", resulting from copying and re-copying of manuscripts.

Based on available evidence, Simuka cannot be dated with certainty. According to one theory, he lived in 3rd century BCE; but he is generally thought to have lived in the 1st century BCE. Epigraphical evidence strongly suggests a 1st-century BCE date for Simuka: Simuka seems to be mentioned as the father the acting king Satakarni in the Naneghat inscription dated to 70-60 BCE, itself considered on palaeographical grounds to be posterior to the Nasik Caves inscription of Kanha (probably Simuka's brother) in Cave 19, dated to 100-70 BCE. Recent analysis of sources puts Simuka's reign possibly around 120 - 96 BCE.

The Mahāsāṃghika (Brahmi: 𑀫𑀳𑀸𑀲𑀸𑀁𑀖𑀺𑀓, "of the Great Sangha", Chinese: 大眾部; pinyin: Dà zhòng bù; Vietnamese: Đại chúng bộ) was a major division (Nikāya) of the early Buddhist schools in India. They were one of the two original communities that emerged from the first schism of the original pre-sectarian Buddhist tradition (the other being the Sthavira Nikāya). This schism is traditionally held to have occurred after the Second Buddhist council, which occurred at some point during or after the reign of Kalashoka. The Mahāsāṃghika Nikāya developed into numerous sects which spread throughout ancient India.

Some scholars think that the Mahāsāṃghika Vinaya (monastic rule) represents the oldest Buddhist monastic source, although some other scholars think that it is not the case. While the Mahāsāṃghika tradition is no longer in existence, many scholars look to the Mahāsāṃghika tradition as an early source for some ideas that were later adopted by Mahāyāna Buddhism. Some of these ideas include the view that the Buddha was a fully transcendent being (term "lokottaravāda", "transcendentalism"), the idea that there are many contemporaneous buddhas and bodhisattvas throughout the universe, the doctrine of the inherent purity and luminosity of the mind (Skt: prakṛtiś ćittasya prabhāsvarā), the doctrine of reflexive awareness (svasaṃvedana) and the doctrine of prajñapti-matra (absolute nominalism or pure conceptualism).

The Spitzer Manuscript is the oldest surviving philosophical manuscript in Sanskrit, and possibly the oldest discovered Sanskritic manuscript of any type related to Hinduism and Buddhism. The manuscript was found in 1906 in the form of a pile of more than 1,000 palm leaf fragments in the Ming-oi, Kizil Caves, China, during the third Turfan expedition headed by Albert Grünwedel. It is named after Moritz Spitzer, whose team first studied it in 1927–28.

The calibrated age by Carbon-14 technique is 130 CE (80–230 CE). According to Indologist Eli Franco, palaeographical features suggest a date closer to 200–230 CE. The text is written in the Brahmi script (Kushana period) and some early Gupta script.

Jambudvīpa (Pali; Jambudīpa) is a term for the Indian Subcontinent, often used in ancient Indian sources.

The term comes from ancient Indian cosmogony and is based on the concept of dvīpa, meaning "island" or "continent". The term Jambudvipa, was used by Ashoka to describe his realm in the 3rd century BC. The same term is also found in subsequent texts, for instance the Kannada inscriptions from the 10th century CE, to refer to the region, presumably ancient India.

The Bengali script or Bangla alphabet is the standard writing system used to write the Bengali language, and has historically been used to write Sanskrit within Bengal. An estimated 300 million people use this syllabic alphabet, which makes it the 5th most commonly used writing system in the world. It is the sole national script of Bangladesh and one of the official scripts of India, specifically used in the Indian states of West Bengal, Tripura and the Barak Valley of Assam. The script is also used for the Meitei language in Manipur, defined by the Manipur Official Language Act.

From a classificatory point of view, the Bengali writing system is derived from the Brahmi script. It is written from left to right. It is an abugida, i.e., its vowel graphemes are mainly realised not as independent letters, but as diacritics modifying the inherent vowel in the base letter to which they are added. There are no distinct upper and lower case letter forms, which makes it a unicameral script. The script is characterised by many conjuncts, upstrokes, downstrokes, and other features that hang from a horizontal line running along the tops of the graphemes that links them together called matra (মাত্রা [ˈmat̪ɾaˑ] 'measure'). The punctuation is all borrowed from 19th-century English, with the exception of one.

Samataṭa (Brahmi script: sa-ma-ta-ṭa) was an ancient geopolitical division of Bengal in the eastern Indian subcontinent. The Greco-Roman account of Sounagoura is linked to the kingdom of Samatata. Its territory corresponded to much of present-day eastern and southern Bangladesh (particularly Dhaka division, Barisal division, Sylhet Division, Khulna Division and Chittagong Division) and the undivided 24 Parganas district in southern West Bengal. The area covers the trans-Meghna part of the Bengal delta. It was a center of Buddhist civilisation before the resurgence of Hinduism, and Muslim conquest in the region.

Archaeological evidence in the Wari-Bateshwar ruins, particularly punch-marked coins, indicate that Vanga-Samataṭa region was probably a province of the Mauryan Empire. The region attained a distinct Buddhist identity following the collapse of Mauryan rule. The Allahabad pillar inscriptions of the Indian emperor Samudragupta is the earliest reference of Samataṭa in which it is described as a tributary state.

The Balinese script, (Balinese: ᬅᬓ᭄ᬱᬭᬩᬮᬶ, Aksara Bali, pronounced [aksarə ˈbali]) also known as hanacaraka (Balinese: ᬳᬦᬘᬭᬓ), is an abugida used in the island of Bali, Indonesia, commonly for writing the Austronesian Balinese language, Old Javanese, Malay and the liturgical language Sanskrit. With some modifications, the script is also used to write the Sasak language, used in the neighboring island of Lombok. In the present day it is also sometimes used to write the national language Indonesian.

The script is a descendant of the Brahmi script, and so has many similarities with the modern scripts of South and Southeast Asia. The Balinese script, along with the Javanese script, is considered the most elaborate and ornate among Brahmic scripts of Southeast Asia.
