Dingal
Dingal (Devnagari: डिंगल; IAST: ḍiṁgala; also spelled Dimgala), also known as Old Western Rajasthani, is an ancient Indian language written in Nagri script and having literature in prose as well as poetry. It is a language of very high tone and requires a specific style of speaking. Dingal was used in Rajasthan and adjoining areas including Gujarat, Kutch, Malwa, and Sindh. Most of Dingal literature is said to be composed by Charans. It was prominently used in composition of war poetry praising the martial exploits of Rajput and Charan war heroes. Dingal is a New Indo-Aryan (NIA) poetic language or style. It is called by various names such as Maru-Bhasha, Marwari, and Old Western Rājasthāni. Dingal is also described as one of five "pre-modern Hindi literary dialects", listed together with Braj, Avadhi, Sadhu and Maithili. Dingal has also been called as the ancestor of Marwari and Gujarati. Origins and Antiquity of Dingal 
The earliest reference of the term 'Dingal' is found in the 8th-century text Kuvalayamālā, composed by Udhyotana Sūrī. According to Dingal scholar Kaviya, Dingal came into existence by the 9th-century, derived from the Apabhramsa of Western Rajasthan, and became the literary language of the region and beyond. The usage of the word "Dingal" is also found in "Uḍiṁgala Nāma Mālā" by the Jain poet Vācaka Kuśalābha and in "Nāga Damana" by the saint-poet Sāyājī Jhūlā, both written at the beginning of the 15th century. According to Jhaverchand Meghani, Dingal, the Charan tongue, was developed from Apbhramsha and Prakrit. Meghani considered Dingal both as a language and poetic medium which "flowed freely between Rajasthan and Suarashtra and conformed to the contours of other phonetic tongues like Sindhi and Kutchi".Uktiratnākara by Sādhu Sundara is not a bardic work, but a work on grammar in the form of an etymological glossary , and its chief importance lies in the fact that it throws a considerable light on the Old Mārwāri of the beginning of the seventeenth century A.D. I have shown elsewhere that the Dingaļa language of the Cāraṇas of Rajputana is ultimately but Old Mārwārī, or , to use a more comprehensive term , Old Western Rājasthāni. -L. P. Tessitori (1916)

Vocabulary 
An interesting feature of Dingal is that it preserves archaic words from the early medieval period which are not found anywhere else. Dingal distinguishes itself from other Northern Indo-Aryan languages since it contains older language forms and also incorporates novel grammatical and lexical constructs. Owing to its geographical origin at Western Rajasthan, Dingal vocabulary also shares words common with Sindhi, Persian, Punjabi, and Sanskrit. Tessitori explains the archaic vocabulary of Dingal poets as follows: "The bards have been more conservative in the matter of lexicon than in the matter of grammar, and most of the poetical and archaic words which were used by them five hundred years ago, can still be used by the bards of the present day, though their meaning may be no longer intelligible to any of his hearers or readers, but the initiated. This fact of the preservation of archaic words in Ḍiṇgaḷa is easily explained by the existence of the poetical glossaries such as the Hamīranāmamālā and the Mānamañjarināmamālā, etc., and the large part they have been playing in the curriculum of the studies of the bards for the last three centuries or more. A great part of these obsolete words are borrowed from the vocabulary of the Sanskrit poetry, and it is chiefly to these that the extraordinary richness in synonyms of Ḍiṇgaḷa is ultimately due". Dingal & Maru Bhasha 
Source:

Historically, the language of Western Rajasthan, was known as Dingal. The name Dingal was considered identical to Maru-Bhasha (otherwise called Marwari Bhasha, Marubhum Bhasha, etc.) There are numerous historical examples of statements by Dingal writers which confirm the view that the spoken language of the region is also called Dingal. In Rukamaṇī Maṃgala or Haraji ro Vyanwalo, late 15th-century Akhyan Kavya text, composed by Padam Bhagat is in the spoken language. A couplet found in one of its manuscripts says: ‘The language of my poem is Dingal. It does not know any metre or continuity. It consists of only divine contemplation’. Charan saint Swarupdas in his Pandav Yashendu Chandrika, early 19th-century, says: ‘My language is a mixed one. It contains Dingal, Braj, and Sanskrit, so that all may understand. I beg apology of greater poets for this.’

Charans & Dingal 
Although it is true that most of the Dingal literature was composed by the Charans, other castes also adopted it and made great contributions. In addition to the Charans, Dingal poetry is available in sufficient quantity by many poets of the Rajput, Pancholi (Kayastha), Motisar, Brahmin, Rawal, Jain, Muhata, and Bhat communities. Several Rajput kings wrote poems in Dingal, particularly Maharaja Man Singh Rathore (reign 1803-1843) of Marwar. Dingal Gīt 
Source:

Dingal Gīt is a unique feature of Dingal and is considered to be an invention of Charans. There is an important distinction to be made about Dingal Gits. The notion that these songs were sung is misleading. Dingal Gīts were recited by Charans in a way similar to Vedic hymns. It is a unique feature of Rajasthani poetry. As doha is the most popular metre of Apabhramsa, so is Gīt for Rajasthani. Gīts are of 120 types. Usually, In the Dingal texts of prosody, there have been 70-90 types of Gīts in usage. A Git is like a small poem. Its not to be sung but recited in "high-pitched tones in a peculiar style". Thousands of such Gīts have been written in commemoration of historical deeds. Many of them are contemporary in relation to the historical incident and as such are known as "Sākh rī Kavitā" or the poetry of testimony. Rules for composition 
There are prosodical rules for the composition of a Gīt. They are:-

 Jathā: a special system of poetic composition; there are 18 types of Jathā
 Vaiṇsagāī: alliteration; it is rigidly followed; there are many types of Vaiṇsagāī
 Ukti: a statement, the basis being the speaker, the listener and the object

Morever, a composition has to avoid the dosas (flaws), which are peculiar to the Cāraṇ prosody and are of 11 types. Additionally, there are 22 types of chappay, 12 types of nīsāṇī, and 23 types of dohā. Dictionaries of Dingal
