Does Khaṛī Bolī mean nothing more than Rustic Speech ?

Extract

THIS question arises out of some remarks made by Professor Abdul Haq of the Osmaniya University, Hyderabad, Deccan, who, criticizing views on Khaṛī Bolī (=KB) which I had expressed in my Hist, of Urdu Lit., pp. 5, 8, 9, 13, said :—

hamẽ is se hūī ki ḍākṭar ṣāḥab ne is ko rafa‘ kīā hai, lekin aṣl mẽ yeh bhī mubtilā haī: khaṛī aur kharī kā farq inhõ ne bahut ṣaḥiḥ batāeā. hai, lekin ma‘ne taqrīban vohī rakkhe haī jo kharī ke haī, ya‘ne murawaja, ‘ām, mustanad (standard) zabān ; aur dūsrā gaẓab kīā hai ki Khaṛī Bolī ko ek zabān qarār dīā hai, aur us kī do batāī haī, ek Hindī aur dūsrī Urdū … Khaī Bolī ke ma‘ne Hindostān mẽ ‘ām par gãvārī bolī ke haī jise Hindostān kā, bacca bacca jāntā, hai; voh na koī khāṣ zabān hai, aur na zabān kī koī (Urdu, July, 1933, p. 590.)
