Another view is that as the Gurmukhs, in accordance with the Sikh belief, used to meditate on the letters ਵ, ਹ, ਗ, ਰ which jointly form ਵਾਹਿਗੁਰੂ or Praise of Guru in Sikhism, these letters were called Gurmukhī, or "of the Gurmukhs".
Later, the whole script came to be known as Gurmukhī. Without proper rendering support, you may see question marks, boxes, or other symbols instead of Unicode characters.
For an introductory guide on IPA symbols, see Help: IPA.The Gurmukhī alphabet contains thirty-five letters. The first three are distinct because they form the basis for vowels and are not consonants, and except for æṛa are never used on their own. In addition to these, there are six consonants created by placing a dot (bindi) at the foot (pair) of the consonant (these are not present in Sri Guru Granth Sahib).There are two major theories on how the Proto-Gurmukhī script emerged in the 15th century. Al-Biruni writes that the Ardhanagari script was used in Bathinda and western parts of the Punjab in the 10th century.For some time, Bathinda remained the capital of the kingdom of Bhati Rajputs of the Pal clan, who ruled North India before the Muslims occupied the country.After 1948, when Himachal Pradesh was established as an administrative unit, the local Takri variants were replaced by Devanagari.
Meanwhile, the mercantile scripts of Punjab known as the Laṇḍā scripts were normally not used for literary purposes.The regional Śāradā script evolved from this stage until the 14th century, when it starts to appear in the form of Gurmukhī.Indian epigraphists call this stage Devasesha, while Bedi prefers the name Pritham Gurmukhī or Proto-Gurmukhī.The Laṇḍā scripts were used for household and trade purposes.Compared to the Laṇḍā, Sikh Gurus favoured the use of Proto-Gurmukhī, because of the difficulties involved in pronouncing words without vowel signs.Later in the 20th century, the script was given the authority as the official script of the Punjab, India while in the Punjab, Pakistan the Persianate Shahmukhi alphabet is still in use.
