Khaṛī Bolī (English spelling) KhariBoli

Japanese: Khaṛī Bolī（英語表記）KhariBoli

...From the 14th century onwards, love stories in the Awadhi dialect and epics of Rama worship in a literary version of the Awadhi dialect were written, while lyric poetry of Krishna worship and skillful love poetry were written in a literary version based on the Braj dialect. Then, from the mid-19th century, the Khaṛī Bolī dialect, which had spread widely under the Mughal rule, became the common language, incorporating vocabulary from the earlier literary languages, and took over the modern and contemporary literature, which was mainly prose rather than verse. Looking at the main trends in Hindi literature in roughly chronological order, focusing on their creators and themes, epics such as Narpati Narhar's "Beesardeva Rāso" (12th century) and Chand Bardāi's "Prithbīraj Rāso" (late 12th century?) were written by court poets who freely incorporated folk stories to praise kings and nobles.

…14世紀以降は，アワディー方言による恋愛物語と，同方言を文語化した言語によるラーマ信仰の叙事詩がつくられる一方，ブラジュ方言に基づく文語でクリシュナ信仰の抒情的な詩と技巧的な恋愛詩がよまれるようになった。そして19世紀中ごろからは，ムガル朝治下で広い地域に普及していたカリー･ボーリーKhaṛī Bolī方言が先行の諸文語の語彙をとりいれながら共通語となって，従来の韻文から散文を主とする近･現代文学を担うこととなった。　ヒンディー文学の主要な潮流を，そのつくり手と主題などに着目しながらほぼ年代順に概観すると，ナルパティ･ナルハーの《ビーサルデーバ･ラーソー》(12世紀)，チャンド･バルダーイーの《プリトゥビーラージ･ラーソー》(12世紀末？)などの叙事詩は，宮廷詩人が民間の物語を自由にとりいれながら王侯･貴族をたたえたものである。…
