What are the two types of Bengali language?

There's a misunderstanding! There isn't a single "Bengali language" that splits into two types. There's only one Bengali language, spoken by millions in Bangladesh and India.

However, there are two major dialects of Bengali, each with its own distinct pronunciation and vocabulary:

1. Standard Bengali: This is the official language of Bangladesh and is commonly spoken in West Bengal, India. It's the most widely recognized form of Bengali and is used in formal settings, media, and literature.

2. Eastern Bengali: Also known as "Bangla" or "Chittagonian Bengali," this dialect is spoken primarily in Chittagong Division of Bangladesh. It features distinctive pronunciation and vocabulary compared to Standard Bengali.

It's important to remember that these are dialects, not separate languages. They are mutually intelligible, meaning speakers of both dialects can generally understand each other.
