Gurmukhi

Gurmukhī (Punjabi: ਗੁਰਮੁਖੀ [ˈɡʊɾᵊmʊkʰiː], Shahmukhi: گُرمُکھی) is an abugida developed from the Laṇḍā scripts, standardized and used by the second Sikh guru, Guru Angad (1504–1552). Commonly regarded as a Sikh script, Gurmukhi is used in Punjab, India as the official script of the Punjabi language.

The primary scripture of Sikhism, the Guru Granth Sahib, is written in Gurmukhī, in various dialects and languages often subsumed under the generic title Sant Bhasha or "saint language", in addition to other languages like Persian and various phases of Indo-Aryan languages.

Modern Gurmukhī has thirty-five original letters, hence its common alternative term paintī or "the thirty-five", plus six additional consonants, nine vowel diacritics, two diacritics for nasal sounds, one diacritic that geminates consonants and three subscript characters.

The Gurmukhī script is generally believed to have roots in the Proto-Sinaitic alphabet by way of the Brahmi script, which developed further into the Northwestern group (Sharada-based), the Central group (Nagari-based) and the Eastern group (Siddhaṃ-based), as well as several prominent writing systems of Southeast Asia, in addition to scripts used historically in Central Asia for extinct languages like Saka and Tocharian. Gurmukhi is derived from Sharada in the Northwestern group, of which it is the only major surviving member, with full modern currency. Notable features include:

Gurmukhi evolved in cultural and historical circumstances notably different from other regional scripts, for the purpose of recording scriptures of Sikhism, a far less Sanskritized cultural tradition than others of the subcontinent. This independence from the Sanskritic model allowed it the freedom to evolve unique orthographical features. These include:

and other features.

From the 10th century onwards, regional differences started to appear between the Sharada script used in Punjab, the Hill States (partly Himachal Pradesh) and Kashmir. Sharada proper was eventually restricted to very limited ceremonial use in Kashmir, as it grew increasingly unsuitable for writing the Kashmiri language. With the last known inscription dating to 1204 C.E., the early 13th century marks a milestone in the development of Sharada. The regional variety in Punjab continued to evolve from this stage through the 14th century; during this period it starts to appear in forms closely resembling Gurmukhī and other Landa scripts. By the 15th century, Sharada had evolved so considerably that epigraphists denote the script at this point by a special name, Dēvāśēṣa. Tarlochan Singh Bedi (1999) prefers the name prithamă gurmukhī, or Proto-Gurmukhī.

Meanwhile, the mercantile scripts of Punjab known as the Laṇḍā scripts were normally not used for literary purposes. Laṇḍā means alphabet "without tail", implying that the script did not have vowel symbols. In Punjab, there were at least ten different scripts classified as Laṇḍā, Mahajani being the most popular. The Laṇḍā scripts were used for household and trade purposes. In contrast to Laṇḍā, the use of vowel diacritics was made obligatory in Gurmukhī for increased accuracy and precision, due to the difficulties involved in deciphering words without vowel signs.
