Bengali Numbers 1 to 100: How to Count in Bangla

Ask a Bengali-speaking friend to count to twenty and watch what happens. They'll start smoothly — এক, দুই, তিন — and then, somewhere around eleven, the forms stop following any predictable rule. By nineteen, every number sounds unique. Bengali has one of the most individual number systems in all of South Asia: practically every number from 1 to 99 carries its own distinct word form. If you need to handle phone numbers, prices, or bus routes in Kolkata or Dhaka, this is the system you need to know.

Bengali Numerals: The Script First

Before the spoken words, the written digits. Bengali uses its own numeral set — not the 0–9 Arabic numerals that dominate most of the world, though those appear on urban signage too. Knowing the native numerals matters for reading price boards, timetables, and any handwritten text.

Bengali Numeral	Value	Word	Romanization	IPA
০	0	শূন্য	shunno	/ʃunno/
১	1	এক	ek	/ek/
২	2	দুই	dui	/d̪ui/
৩	3	তিন	tin	/t̪in/
৪	4	চার	char	/tʃar/
৫	5	পাঁচ	panch	/pantʃ/
৬	6	ছয়	chhoy	/tʃʰɔj/
৭	7	সাত	shat	/ʃat̪/
৮	8	আট	aat	/at/
৯	9	নয়	noy	/nɔj/
১০	10	দশ	dosh	/d̪ɔʃ/

One note on spelling: several romanizations online use "dash" for দশ (10). The forms in this table reflect standard West Bengal pronunciation. Dhaka speakers soften certain consonants slightly, but the number words themselves are the same across the border.

Numbers 11–20: Where the Irregularity Starts

This is where most learners get caught. In English, "eleven" and "twelve" are irregular before "-teen" kicks in. Bengali applies that same logic to every single number from 11 through 19 — and then doesn't stop there.

Number	Bengali Script	Romanization
11	এগারো	egaro
12	বারো	baro
13	তেরো	tero
14	চোদ্দো	choddo
15	পনেরো	ponero
16	ষোলো	sholo
17	সতেরো	shotero
18	আঠারো	atharoh
19	উনিশ	unish
20	বিশ	bish

Twenty is বিশ (bish) — not a compound, not "two-tens." It is its own word, and so is every other decade. Thirty is ত্রিশ (trish). Forty is চল্লিশ (challish). Bengali does not stack digits and decades the way Hindi or German does. Each round number is learned as a single unit, full stop.

The উন- prefix at 19 is worth noticing early: উনিশ (unish) means something close to "one less than twenty." That pattern reappears at 29 (উনত্রিশ, unotrish), 39 (উনচল্লিশ, unochallish), and all the way through the nineties.

The Decades: Each One Its Own Word

Decade	Bengali Script	Romanization
20	বিশ	bish
30	ত্রিশ	trish
40	চল্লিশ	challish
50	পঞ্চাশ	ponchash
60	ষাট	shaat
70	সত্তর	shottor
80	আশি	ashi
90	নব্বই	nobboi
100	একশো	ekshoh

One genuinely confusing pair: সাত (shat, seven) and ষাট (shaat, sixty) are near-homophones in casual Kolkata speech. Context usually saves you, but if you're hearing a price quoted in a market, pay attention to what surrounds the number.

The Compound Numbers: How 21–99 Actually Work

This is where Bengali gets most interesting. The compound forms from 21 through 99 don't simply combine digit and decade. Vowels shift, syllables contract, and the result often looks nothing like its parts. Here are some instructive examples:

Number	Bengali Script	Romanization	What's happening
21	একুশ	ekush	Contraction of এক + বিশ
25	পঁচিশ	ponchish	পাঁচ shifts to পঁচ- in compounds
32	বত্রিশ	bottrish	ত্রিশ absorbs দুই, first syllable shifts
45	পঁয়তাল্লিশ	poitallish	Four syllables — take it slowly
51	একান্ন	ekann	Heavy contraction of পঞ্চাশ + এক
69	উনসত্তর	unoshottor	উন- prefix = "one less than 70"
75	পঁচাত্তর	ponchattir	পাঁচ + সত্তর, vowel shift throughout
99	নিরানব্বই	niranobboi	"One less than 100" logic again

The most practical learning strategy: don't memorize all 99 forms at once. Bengali children absorbed these over years of everyday speech. A better sequence for adult learners: anchor 1–10 cold, learn 11–20 as a block, learn the decade words, then pick up compound forms as you encounter them at market stalls, on receipts, and in phone numbers. Repetition in context does the work that flash cards rarely finish.

Practical Bengali Numbers: Phone, Price, and Time

Knowing the words is one thing. Knowing how they actually appear in daily speech is another.

Phone Numbers

Bengalis typically read phone numbers in pairs or triplets, not digit by digit. A number like 98300-12345 spoken aloud sounds like:

নয়-আট-তিন-শূন্য-শূন্য — এক-দুই-তিন-চার-পাঁচ
noy-aat-tin-shunno-shunno — ek-dui-tin-char-panch

Single digits throughout — no compounding in phone contexts. You'll also hear শূন্য (shunno, zero) rather than any other word for 0.

Prices in Markets and Shops

In Kolkata markets and Dhaka bazaars, prices land on round figures or common contracted amounts. A few phrases you'll hear constantly:

• কত দাম? (koto dam?) — "How much does it cost?"
• পঞ্চাশ টাকা (ponchash taka) — "Fifty rupees/taka"
• একশো বিশ (ekshoh bish) — "One hundred and twenty"
• আড়াইশো (araishoh) — "Two hundred and fifty" — a contracted form that won't come from first principles

আড়াইশো (araishoh) is worth memorizing directly. It's what you'll hear in everyday transactions for 250, not a logical derivation.

Telling the Time

Bengali clock time attaches the suffix -টা (-ta) to the hour:

• ৩টা বাজে (tin-ta baje) — "It's three o'clock"
• সাড়ে চারটা (sharey char-ta) — "Half past four" (সাড়ে means "half past")
• পৌনে পাঁচটা (poune panch-ta) — "Quarter to five"

Ordinal Numbers: First, Second, Third

Once you have the cardinals, ordinals come quickly. Bengali forms ordinals by adding -তম (-tom) to the number, or by using a short set of irregular forms for the first few.

• প্রথম (prothom) — first (irregular, from Sanskrit)
• দ্বিতীয় (dwitio) — second (irregular, literary)
• তৃতীয় (tritio) — third (irregular, literary)
• চতুর্থ (choturth) — fourth (irregular)
• পঞ্চম (ponchom) — fifth (irregular)

From six onward, everyday Bengali uses a simpler system: the cardinal number plus the word নম্বর (nombor, "number"):

• ছয় নম্বর (chhoy nombor) — "sixth" or "number six" in many practical contexts
• দশ নম্বর (dosh nombor) — "tenth"
• পঁচিশ নম্বর বাস (ponchish nombor bash) — "the number 25 bus"

The bus-route usage is worth noting. Kolkata's bus network uses number identifiers extensively, so phrases like ponchish nombor bash or ekat nombor tram are essential for getting around the city. The literary ordinals (প্রথম, দ্বিতীয়, etc.) appear in formal writing, rankings, and academic contexts — not typically in street speech.

Talking About Age

Bengali uses a specific construction for age questions that combines numbers with the word বছর (bochor, "year"):

• আপনার বয়স কত? (Apnar bois koto?) — "How old are you?" (formal)
• আমার বয়স ত্রিশ বছর। (Amar bois trish bochor.) — "I am thirty years old."
• ও সাত বছর বয়সী। (O shat bochor boishi.) — "She/he is seven years old."

The word বয়স (bois) means "age" and sits between the possessive pronoun and the number in the answer structure. This age-stating formula is one of the first places compound numbers come up in real conversation — you'll say your actual age, which for most adults means a two-digit form you'll want to have ready.

একুশ: Why the Number 21 Carries Weight

A cultural note that matters. একুশ (ekush, 21) is not just an arithmetic fact in Bangladesh. The 21st of February — ভাষা শহীদ দিবস (bhasha shohid dibosh, Language Martyrs' Day) — commemorates the students killed in Dhaka in 1952 while protesting for Bengali's official recognition as a state language. UNESCO later declared February 21 International Mother Language Day in 1999. When a Bangladeshi speaker says "একুশ" in a certain tone, they may well mean that date rather than the number.

Remembering 1–100 Without Rote Drilling

The most efficient approach skips the urge to chart all 99 forms in a single weekend. Bengali children absorbed these over years of speech, not through flashcard sessions.

Anchor the ten digits and zero first. Learn 11–20 as a single memorized block — they're different enough from each other that they stick best as a group, not as a system. Add the nine decade words (বিশ, ত্রিশ, চল্লিশ, পঞ্চাশ, ষাট, সত্তর, আশি, নব্বই, একশো) and you'll have the skeleton of the whole system. Then let compound forms arrive naturally: receipts, bus route boards, phone numbers spoken by colleagues, prices at a fish market. Each real transaction reinforces two or three new forms at once, with context that makes them stick.

One further shortcut: many of the numbers from 21 to 99 that feel irregular actually follow a small set of contraction patterns. The পঁচ- variant of five appears at 25 (পঁচিশ), 35 (পঁয়ত্রিশ), 45 (পঁয়তাল্লিশ), and so on. Once you've seen the pattern twice, you start to anticipate it. The language is more systematic than it first appears — the system just operates at the level of contractions rather than transparent compounds.

The Learn Bengali app by Brightwood Apps covers numbers in its early units with native-speaker audio for each form — so you hear exactly how a Kolkata speaker contracts পঁয়তাল্লিশ (poitallish) in natural speech, rather than guessing from the spelling alone.
