Grammar Rule in 30 Seconds

Persian numbers 11-19 use a suffix system, while 20-90 use distinct decade names plus the unit digit.

  • 11-19: Add 'dah' (10) to the unit, e.g., 'yazdah' (11).
  • 20-90: Use the decade name (e.g., 'bist' for 20) followed by the unit.
  • Compound numbers: Connect the decade and unit with 'o' (and), e.g., 'bist-o-yek' (21).
Decade + o + Unit = Compound Number (e.g., 20 + o + 1 = 21)

Overview

Mastering numbers beyond ten is a fundamental step in achieving fluency in Persian. For learners at the A1 CEFR level, understanding Persian numbers from 11 to 100 unlocks essential daily interactions, from stating your age to understanding prices. While initially challenging due to a combination of unique words and a logical combining system, Persian counting is built on a clear, consistent pattern once past the initial teens. This guide will provide a structured, comprehensive approach to learning these numbers, focusing on pronunciation, written forms, and practical application.

How This Grammar Works

Persian, like English, operates on a decimal number system, using powers of ten. However, while the Persian script itself is written from right to left, Persian numerals are consistently written from left to right, following the international standard. For instance, the number 12 is written ۱۲ (davāzdah) and not ۲۱.
This visual convention is crucial to internalize early to avoid confusion.
A key feature of Persian numbers from 21 to 99 is the use of a connecting particle. This particle, represented by the letter و (vāv), functions as and to link the 'tens' digit with the 'units' digit. This و is pronounced as a short o sound, seamlessly joining the two parts of the number.
For example, 21 is بیست و یک (bist-o-yek), literally twenty and one. This logical construction reduces the need for extensive memorization beyond the base numbers and the tens.
Unlike some other languages, Persian numbers do not inflect for grammatical gender, case, or definiteness. The form of the number remains constant regardless of the noun it modifies. This simplifies usage considerably for learners, as you don't need to adjust the number form when counting masculine or feminine nouns.
For instance, سه کتاب (seh ketāb, three books) and سه گل (seh gol, three flowers) use the same form of سه (seh), ensuring predictability.

Formation Pattern

1
Mastering Persian numbers 11-100 involves three distinct stages: memorizing the unique teens (11-19), learning the core tens (20, 30, etc.), and then applying a simple combining rule for all other two-digit numbers. Understanding these stages sequentially is key.
2
I. The Teens (11-19)
3
These numbers are foundational and behave somewhat irregularly. They generally incorporate the concept of ده (dah, ten) but are expressed as single, unique words. Direct memorization is the most effective approach for an A1 learner.
4
| Number | Persian Script | Transliteration | Notes |
5
| ------ | -------------- | --------------- | -------------------------------------------------- |
6
| 11 | یازده | yāzdah | |
7
| 12 | دوازده | davāzdah | |
8
| 13 | سیزده | sizdah | |
9
| 14 | چهارده | chahārdah | |
10
| 15 | پانزده | pānzdah | Colloquially often پونزده (poonzdah) |
11
| 16 | شانزده | shānzdah | |
12
| 17 | هفده | hefdah | Colloquially often هیوَده (hivdah) |
13
| 18 | هجده | hejdah | |
14
| 19 | نوزده | nūzdah | |
15
Notice that most of these numbers explicitly contain or implicitly derive from ده (dah). For example, یازده (yāzdah) is یک (yek, one) + ده (dah). Phonological shifts in پانزده (pānzdah/poonzdah) and هفده (hefdah/hivdah) are common in spoken Persian for ease of articulation. Using these colloquial variants will make your speech sound more natural; for instance, پونزده تومن (poonzdah toman) means fifteen Tomans.
16
II. The Tens (20, 30, ..., 90) and One Hundred (100)
17
These are the essential building blocks for all other two-digit numbers. Each 'ten' has its own unique word.
18
| Number | Persian Script | Transliteration |
19
| ------ | -------------- | --------------- |
20
| 20 | بیست | bist |
21
| 30 | سی | si |
22
| 40 | چهل | chehel |
23
| 50 | پنجاه | panjāh |
24
| 60 | شصت | shast |
25
| 70 | هفتاد | haftād |
26
| 80 | هشتاد | hashtād |
27
| 90 | نود | navad |
28
| 100 | صد | sad |
29
The word for 100, صد (sad), stands alone. Its pronunciation is crucial: it sounds like sæd (IPA /sæd/) or sod, not the English word sad. This distinct pronunciation helps avoid confusion. For example, صد نفر (sad nafar) means one hundred people.
30
III. The Combinations (21-99)
31
This is where Persian numbering becomes remarkably systematic. For any number between 21 and 99 that is not one of the teens, you combine the appropriate 'ten' with the appropriate 'unit' (1-9) using the connector و (vāv, pronounced as o).
32
The Rule: [Ten] + و + [Unit (1-9)]
33
The و (vāv) is always written, but in speech, it becomes a brief o sound, linking the two parts. It is never pronounced as va in this context.
34
Examples:
35
21: بیست و یک (bist-o-yek) – twenty and one
36
بیست (bist) (twenty) + و (o) + یک (yek) (one)
37
35: سی و پنج (si-o-panj) – thirty and five
38
سی (si) (thirty) + و (o) + پنج (panj) (five)
39
48: چهل و هشت (chehel-o-hasht) – forty and eight
40
چهل (chehel) (forty) + و (o) + هشت (hasht) (eight)
41
67: شصت و هفت (shast-o-haft) – sixty and seven
42
شصت (shast) (sixty) + و (o) + هفت (haft) (seven)
43
99: نود و نه (navad-o-noh) – ninety and nine
44
نود (navad) (ninety) + و (o) + نه (noh) (nine)
45
This pattern is highly predictable, making it significantly easier to construct and understand larger numbers once the fundamental 'tens' and 'units' are memorized. The elegance of this system lies in its consistent application.
46
IV. Persian Digits (۰-۹)
47
In addition to the spoken and written words, it is essential to recognize and write Persian numerals, often called Eastern Arabic numerals. These are distinct from the Western Arabic numerals (0-9).
48
| Western | Persian Digit |
49
| ------- | ------------- |
50
| 0 | ۰ |
51
| 1 | ۱ |
52
| 2 | ۲ |\
53
| 3 | ۳ |\
54
| 4 | ۴ |\
55
| 5 | ۵ |\
56
| 6 | ۶ |\
57
| 7 | ۷ |\
58
| 8 | ۸ |\
59
| 9 | ۹ |\
60
Crucially, Persian numbers, whether in script or digit form, are always read and interpreted from left to right. This means ۹۵ is ninety-five (نود و پنج, navad-o-panj), not five-and-ninety. This left-to-right convention is universal in Persian contexts, from price tags to phone numbers and dates. Familiarity with them is as important as knowing the words themselves.

When To Use It

Numbers from 11 to 100 are integral to daily communication in Persian, demanding both recognition and active production.
  • Stating Age (سن - senn): A common use. When asked چند سالتونه؟ (chand sāletune?,
    How old are you?
    ), you respond with ... سالمه (... sāleme,
    I am ... years old
    ).
  • من بیست و سه سالمه. (man bist-o-seh sāleme.) -
    I am twenty-three years old.
  • برادرم هفده سالشه. (barādar-am hefdah sāleshe.) -
    My brother is seventeen years old.
    (Colloquially hivdah is common).
  • Shopping and Prices (قیمت - gheymat): Everyday transactions often involve these numbers, even if larger sums are discussed in thousands or millions. Iranians frequently quote prices in تومان (Tomān), where one تومان (Tomān) equals ten ریال (Riyāl). So, پانزده تومن (pānzdah toman) typically means 15,000 Riyals.
  • این کتاب چهل و پنج هزار تومنه. (in ketāb chehel-o-panj hezār tomāne.) -
    This book is forty-five thousand Tomans.
    (Meaning 450,000 Riyals).
  • یک کیلو سیب سی و دو تومن میشه. (yek kilo sib si-o-do toman mishe.) -
    One kilo of apples is thirty-two Tomans.
    (Meaning 320,000 Riyals).
  • Telling Time (ساعت - sā'at): Used for minutes past the hour, or specific hour combinations.
  • ساعت شش و ده دقیقه است. (sā'at shesh-o-dah daghighe ast.) - "It's six and ten minutes (6:10)."
  • ساعت هشت و چهل و پنج دقیقه است. (sā'at hasht-o-chehel-o-panj daghighe ast.) - "It's eight and forty-five minutes (8:45)."
  • Phone Numbers (شماره تلفن - shomāreye telefon): While often recited digit by digit, some speakers might group numbers, especially in the teens or tens, for speed or clarity.
  • شماره من نود و یک، سی و چهار، بیست و نه، پنجاه و هفت است. (shomāreye man navad-o-yek, si-o-chahār, bist-o-noh, panjāh-o-haft ast.) -
    My number is ninety-one, thirty-four, twenty-nine, fifty-seven.
  • Counting Objects (شمارش اجناس - shomāresh-e ajnās): From groceries to people in a group. The word تا (tā) is often used as a counter word.
  • بیست و پنج دانشجو در کلاس هستند. (bist-o-panj dāneshju dar kelās hastand.) -
    There are twenty-five students in the class.
  • ما هفتاد و شش تا رأی گرفتیم. (mā haftād-o-shesh tā ra'y gereftim.) -
    We got seventy-six votes.

Common Mistakes

Learners frequently encounter specific pitfalls. Understanding the linguistic reasons behind these errors accelerates mastery.
  • Confusion between Teens and Tens: A frequent error involves pairs like شانزده (shānzdah, 16) and شصت (shast, 60).
  • The WHY: Both share initial sounds (sh-). The زده (zdah) suffix distinctly marks the teen numbers. The 'tens' (شصت - shast) are shorter words without this suffix.
  • Correction: Pay close attention to the dah suffix for teens. Practice minimal pairs like پانزده (pānzdah, 15) vs. پنجاه (panjāh, 50). Over-articulate the endings initially.
  • Omitting the Connector و (o): Saying بیست یک (bist yek) instead of بیست و یک (bist-o-yek) for 21.
  • The WHY: Learners may transfer English direct juxtaposition (e.g., twenty-one). In Persian, و (o) is a mandatory grammatical link.
  • Correction: Always remember the و (o) for numbers 21-99. Practice saying numbers aloud, exaggerating the o sound until it feels natural. Think of it as [Ten] + AND + [Unit].
  • Reading Digits Right-to-Left: Interpreting ۸۵ as 58 instead of 85.
  • The WHY: The Persian script is read right-to-left. However, Persian *numerals* adhere to the international left-to-right convention.
  • Correction: Consciously override the text-reading habit when encountering digits. Always scan digits from left to right for their value.
  • Incorrect Pronunciation of صد (sad, 100): Pronouncing it like the English word sad.
  • The WHY: Homographs with English words can create interference.
  • Correction: The ا in صد (sad) is a short vowel, sounding like sæd (IPA /sæd/) or sod. It is not the long 'a' sound of sad. Listen to native speakers carefully.
  • Ignoring Colloquial Variations: Strictly using پانزده (pānzdah) or هفده (hefdah) when پونزده (poonzdah) or هیوَده (hivdah) are more common.
  • The WHY: Learners are often taught formal Persian first and fear incorrect usage.
  • Correction: While formal forms are correct, integrating پونزده (poonzdah) and هیوَده (hivdah) into informal spoken Persian shows greater fluency.

Real Conversations

Understanding numbers in authentic Persian dialogue is crucial. These examples show numbers integrated into common social and transactional contexts.

- Buying Groceries at the Bazaar (Informal):

A

A

سلام آقا، این سیبا چندن؟ (salām āghā, in sibā chandan?) -
Hello sir, how much are these apples?
B

B

سی و پنج تومن خانم. (si-o-panj toman khānom.) - Thirty-five Tomans, madam.
A

A

B

B

من بیست و چهار سالمه. تو چی؟ (man bist-o-chahār sāleme. to chi?) - "I'm twenty-four. How about you?"
A

A

من نوزده سالمه. (man nūzdah sāleme.) - "I'm nineteen."

- Observation: بیست و چهار (bist-o-chahār, 24) and نوزده (nūzdah, 19) are used directly. The context is informal, indicated by چند سالته؟.

- Checking Meeting Time (Formal/Semi-formal):

A

A

بله، سه و سی و پنج دقیقه اونجا هستم. (bale, seh-o-si-o-panj daghighe unjā hastam.) - "Yes, I'll be there at three-thirty-five."

- Observation: سی (si, 30) and سی و پنج (si-o-panj, 35) are used. Note the repetition of و (o) in سی و پنج دقیقه (si-o-panj daghighe), emphasizing its consistent use to link tens and units.

- Social Media Interaction (Modern Colloquial):

A

A

وای! بیست و هشت تا لایک گرفتم تو اینستاگرام! (vāy! bist-o-hasht tā lāyk gereftam tu Instagram!) -
Wow! I got twenty-eight likes on Instagram!
B

B

Great! Your post was very good, you should have gotten at least fifty likes.

- Observation: بیست و هشت (bist-o-hasht, 28) and پنجاه (panjāh, 50) appear in a modern, informal context, demonstrating integration into discussions of digital metrics.

Quick FAQ

Addressing common questions clarifies doubts and reinforces understanding of subtleties in Persian numbers.
  • Q: Why does پانزده (pānzdah) sound like پونزده (poonzdah) and هفده (hefdah) like هیوَده (hivdah) in casual speech?
  • A: This is a natural phonological process in Persian. The vowel /ā/ in پانزده (pānzdah) often shifts to /u/ (or a sound close to 'oo') near certain consonants, making it پونزده (poonzdah). Similarly, /f/ in هفده (hefdah) can vocalize or assimilate, leading to هیوَده (hivdah). These shifts simplify pronunciation in rapid, informal conversation. Using these colloquial forms sounds more natural.
  • Q: Do I always have to use the و (o) connector between the tens and units?
  • A: Yes, grammatically, و (o) is required for numbers 21-99. Omitting it will sound incorrect. Think of it as a mandatory small bridge. While written و (vāv), it's almost always pronounced as a short o sound, never va, in this numerical context.
  • Q: What's the difference between formal and informal pronunciation for these numbers?
  • A: For most numbers 11-100, formal and informal pronunciations are identical, especially for 'tens' and 'units'. The primary informal variations are پانزده (pānzdah \u2192 پونزده (poonzdah)) and هفده (hefdah \u2192 هیوَده (hivdah)). In very rapid casual speech, the o in و (o) might be pronounced very fleetingly, but it's still mentally present.
  • Q: How do I distinguish between ده (dah, 10) and صد (sad, 100) or سی (si, 30) and سه (seh, 3)?
  • A: The key is listening to final consonants and vowel lengths. ده (dah) ends with a clear /h/. صد (sad) is sæd or sod. سی (si) has a distinct long /i/ vowel, while سه (seh) has a short /e/. Practice distinguishing these minimal pairs through listening exercises.
  • Q: Is it important to learn the Persian digits (۰ ۱ ۲ ۳ ۴ ۵ ۶ ۷ ۸ ۹) right away?
  • A: Absolutely. You will encounter these digits everywhere: prices, addresses, phone numbers, and dates. Being able to read and recognize them is fundamental for navigating daily life and any form of written Persian. Treat them as essential vocabulary alongside the spoken words.
  • Q: If Persian is written right-to-left, why are numbers written left-to-right?
  • A: This is a historical convention from the Hindu-Arabic numeral system, which was typically written left-to-right. This convention was maintained even as the script for words evolved differently across cultures like Arabic and Persian. It provides a universal standard for numerical representation, facilitating cross-cultural communication.
