Persian forms a direct measure phrase as number + unit + measured noun: دو کیلو برنج do kilo berenj “two kilos of rice,” سه لیتر آب se litr âb “three liters of water.” No general classifier and normally no ezâfe occur between the measure unit and the substance. English inserts of and pluralizes kilos; Persian does neither.
The broader lexical distinction is covered under Count, Mass, and Measure Nouns; here the central issue is how a numerical measure phrase is assembled.
The same surface string can contain an ordinary noun relation elsewhere. ظرف آب zarf-e âb “the water container/container for water” uses ezâfe because ظرف is being identified by آب, not functioning as a calibrated measure. The difference is grammatical construal, not the material of the container.
Direct measures have a compact shape
| Measure type | Persian | Reading | Structure |
|---|---|---|---|
| weight | دو کیلو برنج | do kilo berenj | number + unit + substance |
| volume | سه لیتر آب | se litr âb | number + unit + substance |
| length | پنج متر پارچه | panj metr pârche | number + unit + material |
| container measure | یک فنجان چای | yek fenjân chây | number + conventional portion + substance |
| ordinary noun relation | ظرف آب | zarf-e âb | head + ezâfe + identifying noun |
سه کیلو برنج برای اردو کافی است.
se kilo berenj barâ-ye ordu kâfi ast.
Three kilos of rice is enough for the camp.
سه لیتر آب داخل مخزن ریختم.
se litr âb dâkhel-e makhzan rikhtam.
I poured three liters of water into the tank.
پنج متر پارچه برای پرده لازم داریم.
panj metr pârche barâ-ye parde lâzem dârim.
We need five meters of fabric for the curtain.
The unit stays singular after the number: دو کیلو, not a Persian plural of کیلو. The measured noun also remains in its base form.
Container portions can behave as measures
Everyday portions such as فنجان “cup,” لیوان “glass,” قاشق “spoon,” and بسته “packet” can occupy the unit slot. When speaker and listener treat them as amounts, the compact measure pattern normally omits ezâfe.
یک فنجان چای بعد از ناهار میخورم.
yek fenjân chây ba'd az nâhâr mi-khoram.
I drink one cup of tea after lunch.
دو قاشق شکر به شیر اضافه کن.
do qâshoq shekar be shir ezâfe kon.
Add two spoonfuls of sugar to the milk.
سه بسته ماکارونی در کابینت مانده است.
se baste mâkâruni dar kâbinet mânde ast.
Three packets of pasta are left in the cupboard.
These containers are not guaranteed scientific units. A قاشق can vary in size, and یک لیوان آب depends on the glass. Syntax presents a portion; context determines precision.
Ordinary container nouns can take ezâfe
When ظرف, بطری, or another container is the object being identified rather than a measuring unit, ordinary ezâfe applies. ظرف آب zarf-e âb can name the water vessel, contrasting with an oil vessel; در ظرف آب dar-e zarf-e âb is “the lid of the water container.”
ظرف آب کنار اجاق نیست.
zarf-e âb kenâr-e ojâq nist.
The water container isn't beside the stove.
در ظرف آب خوب بسته نمیشود.
dar-e zarf-e âb khub baste nemi-shavad.
The lid of the water container doesn't close properly.
Compare دو ظرف آب. In a serving context it can be understood as “two containers of water,” with ظرف serving as a portion expression and no ezâfe. If the intended relation is “two water containers” as objects, speakers may pronounce do zarf-e âb. Context and prosody distinguish the construal; a careful writer can choose دو ظرف پر از آب “two containers full of water” when the contents matter.
Modifiers attach to the measured noun
An adjective describing the substance follows that noun with ezâfe: دو کیلو برنج ایرانی do kilo berenj-e irâni. The absence of ezâfe after the unit does not prevent a later, ordinary ezâfe relation.
دو کیلو برنج ایرانی از بازار خریدیم.
do kilo berenj-e irâni az bâzâr kharidim.
We bought two kilos of Iranian rice at the market.
یک لیوان آب سرد برایش بیاور.
yek livân âb-e sard barâ-yash biyâvar.
Bring her a glass of cold water.
In the second phrase, there is no linker after لیوان, but آب carries -e before سرد. Hearing the exact boundary prevents the learner from treating the entire sequence as one unanalyzed block.
Number-plus-singular syntax extends across units
Time and quantity expressions follow the same singular-after-number principle: ده دقیقه وقت, چهار ساعت کار, شش ماه فرصت. Whether these are best translated with of is an English question, not a Persian rule.
ده دقیقه وقت برای پاسخ دارید.
dah daqiqe vaqt barâ-ye pâsokh dârid.
You have ten minutes to answer.
چهار ساعت کار بیوقفه خستهکننده است.
chahâr sâ'at kâr-e bi-vaqfe khaste-konande ast.
Four hours of nonstop work is tiring.
The number supplies cardinality; neither دقیقه nor ساعت needs plural marking.
General تا changes the packaging
Pure measures do not require counting تا. دو کیلو برنج is the neutral amount. Conversational دو تا بستهی یککیلویی برنج counts two packages, each weighing one kilo. Saying دو تا کیلو برنج may be heard in casual commerce, but it packages kilos as individual units and is not the clean all-register measure pattern.
دو تا بستهی یککیلویی برنج بردار.
do tâ baste-ye yek-kiluyi-ye berenj bardâr.
Take two one-kilo packets of rice. (conversational)
The counter scopes over بسته, not directly over the mass noun برنج.
Specific measured objects and را
A measure phrase can be nonspecific or specific. When a particular measured quantity is the direct object, را follows the entire phrase.
آن دو کیلو برنج را در ظرف بزرگ بریز.
ân do kilo berenj râ dar zarf-e bozorg beriz.
Pour those two kilos of rice into the large container.
سه متر پارچه خریدم، ولی پارچه را هنوز نبریدهام.
se metr pârche kharidam, vali pârche râ hanuz naboride-am.
I bought three meters of fabric, but I haven't cut the fabric yet.
The first mention introduces a quantity without را; the second refers back to the now accessible material and takes را. Measure syntax does not replace discourse specificity.
A short shopping dialogue
چقدر برنج لازم دارید؟
cheqadr berenj lâzem dârid?
How much rice do you need?
دو کیلو برنج و یک بطری روغن میخواهم.
do kilo berenj va yek botri rowghan mi-khâham.
I want two kilos of rice and one bottle of oil.
The reply uses two direct measure expressions without a general classifier and without an English-like of linker.
Common Mistakes
1. Inserting ezâfe into a direct measure
❌ دو کیلو برنج
do kilo-ye berenj
Incorrect neutral measure reading — no ezâfe follows کیلو.
✅ دو کیلو برنج برای شام بپز.
do kilo berenj barâ-ye shâm bepaz.
Cook two kilos of rice for dinner.
2. Pluralizing the unit after a number
❌ سه لیترها شیر خریدیم.
Incorrect — the measure unit remains singular after the numeral.
✅ سه لیتر شیر تازه خریدیم.
se litr shir-e tâze kharidim.
We bought three liters of fresh milk.
3. Adding a general counter to every measure
❌ پنج تا مترها پارچه لازم داریم.
Incorrect — a direct measure needs neither تا nor a plural unit.
✅ پنج متر پارچهی سفید لازم داریم.
panj metr pârche-ye sefid lâzem dârim.
We need five meters of white fabric.
4. Omitting genuine ezâfe in an object relation
❌ در ظرف آب
dar zarf âb
Incorrect intended chain — both ‘lid of the container’ and ‘water container’ require ezâfe.
✅ در ظرف آب شکسته است.
dar-e zarf-e âb shekaste ast.
The lid of the water container is broken.
5. Putting را after the unit alone
❌ آن دو کیلو را برنج بردار.
Incorrect — را follows the complete measured direct object.
✅ آن دو کیلو برنج را از انبار بردار.
ân do kilo berenj râ az anbâr bardâr.
Take those two kilos of rice from storage.
Key Takeaways
- Direct measure phrases use number + singular unit + measured noun, normally without ezâfe.
- Container nouns can be portion units or ordinary heads; ordinary identifying relations take ezâfe.
- A later adjective links to the measured noun: دو کیلو برنج ایرانی.
- General تا is unnecessary for the neutral measure and can change the construal to counted packages or units.
- را follows the complete measured phrase when that quantity is a specific direct object.
