Where Bengali comes from
The line — Māgadhī Prakrit → the eastern (Gauḍa–Baṅga) Apabhraṃśa → Bengali, beside its sisters Assamese and Odia and its cousins the Bihari languages.
The three stages
| Stage | Rough span | Evidence |
|---|---|---|
| Old Bengali (প্রাচীন) | c. 950–1200 | the চর্যাপদ |
| Middle Bengali (মধ্য) | c. 1350–1800 | শ্রীকৃষ্ণকীর্তন, the mangal poems, the Vaishnava songs |
| New Bengali (আধুনিক) | from 1800 | prose, print, the standard colloquial |
The landmark study — Suniti Kumar Chatterji's The Origin and Development of the Bengali Language (1926), known as ODBL, traced Bengali sound by sound from Old Indo-Aryan; it remains the foundation of Bengali linguistics.
A rival view — Muhammad Shahidullah of Dhaka argued for an earlier date for the Charyapada and a descent from a Gauḍī Apabhraṃśa; the debate shows how much of early Bengali history rests on a few texts.
The trap: ODBL is Suniti Kumar Chatterji's work of 1926 — not Sukumar Sen's, whose great work is a history of Bengali literature.

The dialects of Bengali
Sukumar Sen's five groups
| Group | Region | Note |
|---|---|---|
| রাঢ়ী (Rāṛhī) | west-central — Nadia, Kolkata, Hooghly, Burdwan | the basis of standard colloquial Bengali |
| বঙ্গালী (Baṅgālī) | the east — Dhaka, Mymensingh, Barisal and beyond | the speech of much of Bangladesh |
| বরেন্দ্রী (Barendrī) | the north — Rajshahi, Malda | — |
| ঝাড়খণ্ডী (Jhāṛkhaṇḍī) | the south-west — Purulia, Manbhum | on the edge of the Chhotanagpur plateau |
| কামরূপী (Kāmrūpī) | the north-east — Rangpur, Cooch Behar | towards Assamese |
Why Rāṛhī became standard — Kolkata was the capital of print, schooling and government in the 19th century, and the educated speech of Nadia and Kolkata became the model.
On Bihar's eastern edge — around Kishanganj, the Surjapuri speech shades between Bengali and Maithili, a reminder that languages meet in belts, not lines.
The trap: the standard is built on রাঢ়ী (Nadia–Kolkata), not on বঙ্গালী — though more speakers in total use the eastern varieties of Bangladesh.

Sounds and sound change
The inherent vowel — Bengali pronounces the inherent অ as a rounded [ɔ]: কলম is 'kɔlom', not 'kalam' — the first thing a Hindi speaker notices.
য-ফলা doubles the consonant — বিদ্যা is said 'biddā', সত্য 'shotto': the written y becomes a doubling.
Two classic sound changes (from ODBL)
| Change | What happens | Example |
|---|---|---|
| অপিনিহিতি (epenthesis) | an i or u is pronounced before the consonant it follows in writing | রাখিয়া → রাইখ্যা (eastern speech) |
| অভিশ্রুতি (umlaut) | the moved vowel then changes the vowel before it, and drops | রাইখ্যা → রেখে (standard) |
| স্বরসংগতি (vowel harmony) | one vowel becomes like a neighbouring vowel | বিলাতি → বিলিতি · দেশি → দিশি |
Script — the Bengali script (an eastern Nāgarī) is shared with Assamese, which adds its own letters for r and w; special signs include ৎ (khaṇḍa ta), ং and the nasal ঁ (chandrabindu).
The trap: in বিলাতি → বিলিতি the change is vowel harmony (স্বরসংগতি) — no vowel is moved across a consonant, so it is not অপিনিহিতি.

Morphology — what makes Bengali Bengali
No grammatical gender — adjectives and verbs never change for gender; only some nouns have male and female forms by meaning (ছাত্র / ছাত্রী).
Classifiers — Bengali adds a small word to a noun or number to make it definite or to count it:
| Classifier | Use | Example |
|---|---|---|
| -টা · -টি | 'the', one thing; -টি more polite or affectionate | বইটা · বইটি — the book |
| -খানা · -খানি | flat or whole objects | কাপড়খানা — the cloth |
| -গুলো · -গুলি | plural, definite | বইগুলো — the books |
| with numbers | counting | দুটো বই · একজন লোক |
Three grades of 'you' — তুই (intimate), তুমি (familiar), আপনি (respectful), each with its own verb ending.
Negation after the verb — Bengali puts না after the verb: আমি যাই না ('I do not go'); for the past it uses -নি: আমি যাইনি ('I did not go').
The trap: Bengali না follows the verb — 'আমি যাই না' — the reverse of Hindi 'मैं नहीं जाता', where नहीं comes before it.
