The basic Persian counted noun phrase is number + singular noun: چهار بلیت “four tickets,” literally “four ticket.” The noun names the category, while the number already supplies plurality; standard Persian therefore does not copy an English plural ending onto the counted noun.
Persian can insert a counting word between the number and noun. General تا is especially conversational, نفر counts people, and measure nouns such as کیلو and متر specify a unit. These words refine how the quantity is packaged, but they do not change the rule that the directly counted form remains singular.
The neutral pattern: number + singular noun
The numeral precedes the noun. This order holds whether the number is written as a word or with Persian digits.
| Pattern | Persian | Register or function |
|---|---|---|
| number + noun | سه پنجره | neutral in speech and writing |
| number + تا + noun | سه تا پنجره | common conversational counting |
| number + نفر + human noun | سه نفر مهندس | neutral, precise human count |
| number + measure + material | سه متر پارچه | quantity measured in units |
برای سفر دو چمدان کوچک برداشتهایم.
barâ-ye safar do chamedân-e kuchek bardâshte-im.
We have packed two small suitcases for the trip. (neutral standard)
کتابخانه ۴ میز تازه برای سالن خریده است.
ketâbkhâne chahâr miz-e tâze barâ-ye sâlon kharide ast.
The library has bought four new tables for the hall. (neutral; Persian digit and singular میز)
English speakers often feel that singular میز conflicts with a quantity of four. It does not. Morphological number and real-world quantity are separate: چهار makes the phrase semantically plural, while میز stays in its citation form.
Optional تا in conversation
Counting تا follows the numeral and precedes an ordinary discrete noun: دو تا لیوان، پنج تا کلید. It is extremely common in (informal) and neutral conversation, especially in requests and small concrete counts. It is not a compulsory classifier: bare دو لیوان is fully grammatical and more economical in formal inventories.
از آشپزخانه سه تا لیوان تمیز بیاور.
az âshpazkhâne se tâ livân-e tamiz biyâvar.
Bring three clean glasses from the kitchen. (ordinary conversation)
در انبار فقط دو دستگاه چاپگر باقی مانده است.
dar anbâr faqat do dastgâh châpgar bâqi mânde ast.
Only two printers remain in the warehouse. (formal inventory; specific technical counter)
The second example uses دستگاه, not general تا, because the institutional register classifies a machine as a unit of equipment. Counters are lexical choices with register and meaning; Persian does not have one obligatory classifier slot like some East Asian languages.
Do not stack تا with another counter. Say سه نفر مسافر or conversational سه تا مسافر, not سه تا نفر مسافر.
نفر for people
نفر conventionally counts people: دو نفر پزشک, هشت نفر مهمان. It can also stand alone when “people” is understood: هشت نفر آمدند. Because the referents are human and plural, the finite verb normally takes plural agreement even though نفر and the following profession noun have no plural suffix.
شش نفر داوطلب برای مصاحبه دعوت شدند.
shesh nafar dâvtalab barâ-ye mosâhebe da'vat shodand.
Six applicants were invited for an interview. (neutral standard; human plural agreement)
— چند نفر هنوز داخل کلاساند؟ — چهار نفر.
— chand nafar hanuz dâkhel-e kelâs-and? — chahâr nafar.
— How many people are still in the classroom? — Four. (careful spoken standard)
Conversational سه تا دانشجو is also possible (informal), but formal reports prefer سه دانشجو or سه نفر دانشجو. The contrast is one of packaging and register, not grammatical versus ungrammatical Persian.
Measure expressions
A measure phrase has the order number + singular unit + substance or dimension: دو کیلو پرتقال، پنج متر کابل، سه فنجان قهوه. The unit remains singular after the number. The final noun says what is measured and is also normally bare.
برای مربا سه کیلو توتفرنگی لازم داریم.
barâ-ye morabbâ se kilu tut-farangi lâzem dârim.
We need three kilos of strawberries for the jam. (neutral)
فروشنده پنج متر کابل برایم برید.
forushande panj metr kâbel barâ-yam borid.
The seller cut five meters of cable for me. (neutral conversation)
لطفا دو فنجان قهوه و یک لیوان آب بیاورید.
lotfan do fenjân qahve va yek livân âb biyâvarid.
Please bring two cups of coffee and one glass of water. (polite neutral request)
Measure nouns are not automatically interchangeable. دو تا قهوه is natural in a café (informal) because two orders or cups are recoverable; in a recipe, use an explicit unit such as دو فنجان قهوه or دویست گرم قهوه.
The page on Measure Phrases without a General Classifier develops the unit–substance relation further.
Adjectives follow the counted noun
The numeral still comes before the noun, but an ordinary adjective follows the noun through ezâfe: سه کتابِ مفید “three useful books.” Consonant-final ezâfe is normally invisible in writing and audible as -e. Neither the noun nor adjective agrees overtly with the plural quantity.
آن دو اتاق روشن را برای مهمانها آماده کردیم.
ân do otâq-e rowshan râ barâ-ye mehmân-hâ âmâde kardim.
We prepared those two bright rooms for the guests. (neutral standard)
پنج پرسش مهم بیپاسخ مانده است.
panj porsesh-e mohem bi-pâsokh mânde ast.
Five important questions remain unanswered. (formal-neutral; inanimate singular agreement)
The word order is therefore number + noun + ezâfe + adjective, not English number + adjective + noun. A demonstrative comes before the numeral: این پنج پرسش مهم “these five important questions.” Specific object را follows the entire phrase.
Agreement follows the referent
A counted human subject normally takes plural verbal agreement: چهار پرستار رسیدند. Counted inanimate subjects often take singular agreement in formal written Persian, as in پنج پرسش ... مانده است. Plural agreement with individuated inanimate referents is also current, especially in speech. This choice affects the verb, not the singular shape of the noun after the numeral.
سه تاکسی همزمان جلوی هتل توقف کردند.
se tâksi ham-zamân jelow-ye hotel tavaqqof kardand.
Three taxis stopped in front of the hotel at the same time. (neutral modern usage; individuated inanimates with plural agreement)
For the fuller agreement system, see Quantifier and Numeral Syntax.
Common Mistakes
1. Pluralizing the directly counted noun
❌ شش صندلیها برای مهمانها چیدیم.
Incorrect — a noun directly counted by a cardinal normally remains singular.
✅ برای مهمانها شش صندلی کنار پنجره چیدیم.
barâ-ye mehmân-hâ shesh sandali kenâr-e panjare chidim.
We arranged six chairs by the window for the guests.
2. Putting the adjective before the noun
❌ سه جدید کتاب برای دوره خریدم.
Incorrect English-derived order — the adjective follows the Persian noun through ezâfe.
✅ برای دوره سه کتاب جدید خریدم.
barâ-ye dowre se ketâb-e jadid kharidam.
I bought three new books for the course.
3. Treating تا as compulsory
⚠️ در فهرست رسمی چهار تا دستگاه ثبت شده است.
dar fehrest-e rasmi chahâr tâ dastgâh sabt shode ast.
Grammatical, but conversational تا is marked in a formal inventory; omit it or choose a specific unit word.
✅ مرکز درمانی چهار دستگاه تازه سفارش داده است.
markaz-e darmâni chahâr dastgâh-e tâze sefâresh dâde ast.
The medical center has ordered four new machines. (formal-neutral)
4. Using نفر for an object
❌ دو نفر دوچرخه جلوی در است.
Incorrect — نفر counts people, not bicycles.
✅ دو دوچرخه جلوی ورودی پارک شده است.
do docharkhe jelow-ye vorudi pârk shode ast.
Two bicycles are parked by the entrance. (formal-neutral agreement)
5. Pluralizing the measure unit
❌ سه کیلوها برنج برای شام کافی است.
Incorrect — the unit itself remains singular after the numeral.
✅ برای شام سه کیلو برنج کافی است.
barâ-ye shâm se kilu berenj kâfi ast.
Three kilos of rice is enough for dinner.
Key Takeaways
- Use number + singular noun as the neutral default.
- Add تا for conversational item-counting; use نفر for people and precise measure nouns for units.
- Place adjectives after the counted noun through ezâfe.
- Keep measure units singular: سه متر پارچه, not a plural unit.
- Let semantic animacy and discourse packaging guide verbal agreement; do not read agreement directly from the noun’s visible suffix.
