Origins of Words in the Bengali Language

Bengali is typically thought to have around 100,000 separate words, of which 16,000 (16%) are considered to be তদ্ভব tôdbhôbô, or Tadbhava (inherited Indo-Aryan vocabulary), 40,000 (40%) are তৎসম tôtśômô or Tatsama (words directly borrowed from Sanskrit), and borrowings from দেশী deśi, or "indigenous" words, which are at around 16,000 (16%) of the Bengali vocabulary. The rest are বিদেশী bideśi or "foreign" sources, including Persian, Turkish, Arabic, and English among others, accounting for around 28,000 (28%) of all Bengali words, highlighting the significant influence that foreign languages and cultures have had on the Bengali language throughout Bengal's long history of contact with different peoples and the cultural exchanges that came with such interactions. Bengali is reportedly similar to Assamese and has a lexical similarity of 40 per cent with Nepali.

However, these figures do not take into account the large proportion of archaic or highly technical words that are very rarely used. Furthermore, different dialects use more Persian and Arabic vocabulary, especially in different areas of Bangladesh and Muslim majority areas of West Bengal. Hindus, on the other hand, use more Sanskrit vocabulary than Muslims. Standard Bengali is based on the Nadia dialect spoken in the Hindu-majority states of West Bengal and parts of the Muslim-majority division of Khulna in Bangladesh. About 90% of Bengalis in Bangladesh (ca. 148 million) and 27% of Bengalis in West Bengal and 10% in Assam (ca. 36 million) are Muslim and the Bangladeshi Muslims and some of the Indian Bengali Muslims speak a more "Perso-Arabised" version of Bengali instead of the more Sanskrit influenced Standard Nadia dialect although the majority of the Indian Bengalis of West Bengal speaks in Rarhi dialect irrespective of religion.

According to Suniti Kumar Chatterji, dictionaries from the early 20th century attributed a little more than 50% of the Bengali vocabulary to native words (i.e., naturally modified Sanskrit words, corrupted forms of Sanskrit words, and loanwords non-Indo-European languages). About 45% per cent of Bengali words are unmodified Sanskrit, and the remaining words are from foreign languages. However, more modern sources cite that this is not the case with Bengali vocabulary, as there are far more dominant foreign influences that accurately reflect the way modern Bengalis speak and utilize Bengali. Persian is also thought to have influenced a lot of grammatical forms. More recent studies suggest that the use of foreign words has been increasing, mainly because of the preference of Bengali speakers for the colloquial style. Because of centuries of contact with Europeans, Turkic peoples, and Persians, Bengali has absorbed numerous words from foreign languages, often totally integrating these borrowings into the core vocabulary.

Persian influence was significant for the development of Bengali up to the modern day, and was the primary official language in the region for 600 years, until British rule, when it was changed to English in 1836. In fact, there was so much Persian influence that a register of highly Persianized Bengali, known as Dobhashi appeared in medieval Bengal.

The most common borrowings from foreign languages come from three different kinds of contact. After close contact with several indigenous Austroasiatic languages, and later the Delhi Sultanate, the Bengal Sultanate, and the Mughal Empire, whose court language was Persian, numerous Arabic, Persian, and Chaghatai words were absorbed into the lexicon.

Later, East Asian travellers and lately European colonialism brought words from Portuguese, French, Dutch, and most significantly English during the colonial period.
