Bengali language
Alternative and historic scripts

Throughout history, there have been instances of the Bengali language being written in different scripts, though these employments were never popular on a large scale and were communally limited. Owing to Bengal's geographic location, Bengali areas bordering non-Bengali regions have been influenced by each other. Small numbers of people in Midnapore, which borders Odisha, have used the Odia script to write in Bengali. In the border areas between West Bengal and Bihar, some Bengali communities historically wrote Bengali in Devanagari, Kaithi and Tirhuta.

In Sylhet and Bankura, modified versions of the Kaithi script had some historical prominence, mainly among Muslim communities. The variant in Sylhet was identical to the Baitali Kaithi script of Hindustani with the exception of Sylhet Nagri possessing matra. Sylhet Nagri was standardised for printing in c. 1869.

Up until the 19th century, numerous variations of the Arabic script had been used across Bengal from Chittagong in the east to Meherpur in the west. The 14th-century court scholar of Bengal, Nur Qutb Alam, composed Bengali poetry using the Persian alphabet. After the Partition of India in the 20th century, the Pakistani government attempted to institute the Perso-Arabic script as the standard for Bengali in East Pakistan; this was met with resistance and contributed to the Bengali language movement.

In the 16th century, Portuguese missionaries began a tradition of using the Roman alphabet to transcribe the Bengali language. Though the Portuguese standard did not receive much growth, a few Roman Bengali works relating to Christianity and Bengali grammar were printed as far as Lisbon in 1743. The Portuguese were followed by the English and French respectively, whose works were mostly related to Bengali grammar and transliteration. The first version of the Aesop's Fables in Bengali was printed using Roman letters based on English phonology by the Scottish linguist John Gilchrist. Consecutive attempts to establish a Roman Bengali have continued across every century since these times, and have been supported by the likes of Suniti Kumar Chatterji, Muhammad Qudrat-i-Khuda, and Muhammad Enamul Haq. The Digital Revolution has also played a part in the adoption of the English alphabet to write Bengali, with certain social media influencers publishing entire novels in Roman Bengali.

Bengali script like others does have Schwa deletion. It does not mark when the inherent vowel is not used (mainly at the end of words)
