GURMUKHI is the name of the script used in writing primarily Punjabi and, secondarily, Sindhi language. The word gurmukhi seems to have gained currency from the use of these letters to record the sayings coming from the mukh (lit. mouth or lips) of the (Sikh) Gurus. The letters no doubt existed before the time of Guru Angad (even of Guru Nanak) as they had their origin in the Brahmi, but the origin of the script is attributed to Guru Angad. He not only modified and rearranged certain letters but also shaped them into a script. He gave new shape and new order to the alphabet and made it precise and accurate.
ALPHABET (GURMUKHI) Punjabi alphabet is known as Gurmukhi. Since its characters were used for writing and transcribing the biography and hymns of Guru Nanak, it was given this name by the second Sikh Guru, Guru An gad Dev. It is a misnomer to call the Guru as the inventor of its characters, because before the advent of Guru Nanak, their usage had been prevalent according to in a tablet found at A thur in Ludhiana district. Even Guru Nanak himself based one of his poems entitled \'patti\' on its characters. This Alphabet is also called \'Paint is Akhri\' because it contains thirty-five letters.
BAVAN AKHARI, a poem constructed upon 52 (bavan) letters (akhar) of the alphabet. In this form of poetry each verse begins serially with a letter of the alphabet. The origin of the genre is traced to ancient Sanskrit literature. Since the Devanagari alphabet, employed in Sanskrit, comprises fifty-two (bavan, in Hindi) letters (33 consonants, 16 vowels and 3 compounds), such compositions came to be called bavan akharior bavan aksari. Notwithstanding this nomenclature, no such composition consists exactly of fifty-two stanzas as few stanzas will open with a vowel, and the compounds are generally left out of this scheme of poetry.
