Dhakaiya Kutti dialect (Bengali: ঢাকাইয়া কুট্টি উপভাষা, romanized: Dhakaiya Kutti dialect, lit. 'Dhakaiya dialect of the rice-huskers'), also known as Old Dhakaiya Bengali (Bengali: পুরান ঢাকাইয়া বাংলা, romanized: Purān Dhākāiyā Bānglā) or simply Dhakaiya, is a Bengali dialect,^[1] spoken by the Dhakaiya Kuttis of Old Dhaka city in Bangladesh. This dialect is fully mutually intelligible with Standard Bengali but has some differences in vocabulary.^[2] It is not used in formal settings anymore although historically the local Bais and Bara panchayets are said to have used it sometimes.^[3][4]

Dhakaiya Kutti is an eastern dialect of Bengali and the vocabulary of this dialect has some influence of Urdu due to the interactions with Urdu-speaking people of Old Dhaka.^[5] It has only a few aspirated sounds in comparison to Standard Bengali. Some aspirated sounds such as [gʱ], [d̪ʱ], [bʱ] are not pronounced properly in this dialect.^[6] The use of double sounds in certain words are also quite common. The word for younger brother-in-law, shala (শালা) in Standard Bengali and hala (হালা) in Dhakaiya Kutti and other eastern dialects, is seen as offensive in almost all Bengali dialects except in the Dhakaiya Kutti dialect this is a common and inoffensive word which can be applied to teachers, parents and animals.^[6]

During the Mughal era, the Bengal Subah was famous for rice cultivation and the city of Jahangirnagar (now Dhaka) was the province's capital. Rice was a very important export product in the mid-eighteenth century, centred in Dhaka. The merchants who exported the rice were predominantly of Marwari and Central Indian descent. These merchants would go to different areas in Eastern Bengal and collect the rice. The rice was first needed to be cleaned up using dhekis before packaging, and this process is called kuta (কুটা) in Bengali. Many local rice cultivators were employed to do this. They would come from various parts of Bengal to Dhaka to complete this job, and as it was long and tiring to get there and do the job, many of them started living in Dhaka. This migration took place circa 1760. However, not all were involved in the rice trade. The presence of the Mughals in Dhaka meant that there was generally a lot more employment opportunities there and so they took other occupations such as khansamahs, footsoldiers, guards, chefs and chauffeurs for the Dhakaiya Urdu-speaking Nawabs of Dhaka and other aristocratic families.^[7][8] These groups of people lived together and engaged in conversations and addas with their Hindustani counterparts and their main occupation led them to be known as kuttis. The interactions with different cultures and languages led to the birth of the Kutti dialect.^[9] The Bais panchayets of Old Dhaka in the twentieth-century used to converse in either Dhakaiya Urdu or Dhakaiya Kutti.^[4] Eventually, the common people living in the localities of Old Dhaka, Kutti or not, used to speak in this dialect.^[10]

Presently, the speakers of kutti dialect are a minority in Old Dhaka following the mass migration of non-Dhakaiya Bengalis from districts all over Bengal during the first and second partitions during the British colonial period. The new educated migrant community (now also commonly known as Dhakaiyas with the former now being referred to as "Old Dhakaiyas") spoke in Standard Bengali (Bengali: শুদ্ধ বাংলা, romanized: Shuddho Bangla), a standardised dialect of Bengali established by the British. The culture of Kuttis of Old Dhaka is in decline due to the influence of Dhaka city, as the capital, welcoming migrants from all over the country who are not familiar with their regional culture.^[11] Some of the Dhakaiya kutti-Bengali community began to see the new migrant community as their opponents due to these dialectical and cultural differences. This division was the source of modern troubles in the identities of the Old Dhakaiyas (who view themselves as original inhabitants) and the post-partition migrant community (who currently form the majority in the city).^[11]

There has been literature written in the Dhakaiya Kutti dialect. One popular poem is "Channi-poshor Raiter Lour" (চান্নিপশর রাইতের লৌড়) by Jewel Mazhar.^[12] Dhakaiya natoks are popular throughout the country and even the Indian filmmaker, Satyajit Ray, has written dialogues in this dialect.^[13] The Dhakaiya Kutti folk are renowned for "Kutti Jokes" and the dialect's humorous aspect in general; generally consisting of short stories in which Dhakaiyas mess around with the bhadralok gentry.^[14] It is considered to be one of the wittiest among Bengali dialects.^[15] Generally referred to as "Dhakaiya" folk, they call outsiders or non-Dhakaiya Bengalis by the name "Gaiya" (গাঁইয়া), meaning from the village,^[16] and Kolkatans in particular as Demchi (ডেমচি).^[17]
