Marwari and its closely related varieties like Dhundhari, Shekhawati and Mewari form a part of the broader Rajasthani language family.

[8] Formal grammar of Gurjar Apabhraṃśa was written by Jain monk and Gujarati scholar Hemachandra Suri.

Marwari speakers have dispersed widely throughout India and other countries but are found most notably in the neighbouring state of Gujarat and in Eastern Pakistan.

[7] Merwari [wry] shares 82%–97% intelligibility of Pakistani Marwari [mve], with 60%–73% lexical similarity between Merwari varieties in Ajmer and Nagaur districts, but only 58%–80% with Shekhawati [swv], 49%–74% with Indian Marwari [rwr], 44%–70% with Godwari [gdx], 54%–72% with Mewari [mtr], 62%–70% with Dhundari [dhd], 57%–67% with Haroti [hoj].

Unlike Pakistani Marwari [mve], the use of Merwari remains vigorous, even if its most educated speakers also proficiently speak Hindi [hin].

[citation needed] Marwari vocabulary is somewhat similar to other Western Indo-Aryan languages, especially Rajasthani and Gujarati, however, elements of grammar and basic terminology differ enough to significantly impede mutual intelligibility.
