The Bengali alphabet is derived from the Brahmi alphabet. It is also closely related to theDevanagari alphabet, from which it started to diverge in the 11th Century AD. The current printed form of Bengali alphabet first appeared in 1778 when Charles Wilkins developed printing in Bengali. A few archaic letters were modernised during the 19th century.
Bengali has two literary styles: one is called Sadhubhasa (elegant language) and the otherChaltibhasa (current language). The former is the traditional literary style based on Middle Bengali of the sixteenth century, while the later is a 20th century creation and is based on the speech of educated people in Calcutta.
The differences between the two styles are not huge and involve mainly forms of pronouns and verb conjugations.
