Tatsama, Tadbhava, Deshi and Bideshi: The Four Families of Bengali Words
How Bengali traditionally classifies its vocabulary by origin, with examples showing how everyday words descend from Sanskrit.
Bengali grammarians classify the vocabulary of the language into four families. Knowing them helps you see connections between words and pick the right register for a situation.
Tatsama (তৎসম): unchanged Sanskrit
Tatsama words are borrowed directly from Sanskrit with little or no change. They tend to be formal, literary or religious:
- সূর্য (shurjo, sun)
- চন্দ্র (chondro, moon)
- জল (jol, water)
- পুস্তক (pustok, book)
- বিদ্যালয় (bidyalay, school)
- সত্য (shotto, truth)
Tadbhava (তদ্ভব): evolved from Sanskrit
Tadbhava words descend from Sanskrit but have changed over time through Prakrit into everyday Bengali:
- চাঁদ (chand, moon) — from chandra
- হাত (hat, hand) — from hasta
- মাছ (machh, fish) — from matsya
- কাজ (kaj, work) — from karya
- ঘর (ghor, house) — from griha
- দুধ (dudh, milk) — from dugdha
- ভাত (bhat, rice) — from bhakta
- সোনা (shona, gold) — from suvarna
Deshi (দেশি): native words
Deshi words come from local languages of the region that predate or lie outside Sanskrit. Examples include ঢেঁকি (dheki, a rice-husking pedal), ডাব (dab, tender coconut), ঝোল (jhol, broth) and many words for local plants and tools.
Bideshi (বিদেশি): foreign loanwords
Bideshi words come from other languages: Persian, Arabic, Portuguese, English and more, as described in the previous article.
Using the classification
- Tatsama words often appear in formal writing, speeches, names and religious texts.
- Tadbhava words dominate everyday speech.
- Deshi and bideshi words fill in everyday domains such as food, tools, administration and technology.
Same idea, different words
You can often express the same idea at different registers: চন্দ্র (formal) versus চাঁদ (everyday), or সূর্য (formal) versus রবি (poetic). Choosing between them signals tone.
Why the classification helps learners
If you know a few Sanskrit-derived words, tatsama vocabulary becomes easier. If you speak Hindi, Marathi, Nepali or Gujarati, you will notice many tatsama words look similar to those in your language.
Names
Many Bengali names are tatsama, drawn from Sanskrit words with beautiful meanings, such as অনির্বাণ (Anirbaan, unextinguished) or কৃষ্ণা (Krishna).
Practice
- Take ten Bengali words and guess their category.
- Find tatsama and tadbhava pairs.
- Notice when a formal word appears in writing.
- Use a dictionary to check meanings and spelling.
