Persian builds many adjectives from two meaningful elements: وقتگیر vaqt-gir “time-consuming,” مشکلساز moshkel-sâz “problem-causing,” یخزده yakh-zade “frozen,” سختکوش sakht-kush “hard-working,” and کمحرف kam-harf “quiet/not talkative.” The compound acts as one adjective even when its internal meaning remains transparent.
This unity matters syntactically. In همکار سختکوش hamkâr-e sakht-kush, ezâfe links the noun همکار to the complete adjective سختکوش; there is no ezâfe between سخت and کوش. Compound spelling is lexical, however: modern standard Persian uses solid spelling or ZWNJ according to the individual word, not one visible separator for every compound.
A construction map
| Type | Example | Internal source | Whole meaning |
|---|---|---|---|
| noun + present stem | وقتگیر | وقت “time” + گیر “take” | time-consuming |
| noun + present stem | مشکلساز | مشکل “problem” + ساز “make” | problematic; causing problems |
| noun + participle | یخزده | یخ “ice” + زده “struck/affected” | frozen |
| noun + participle | آفتابسوخته | آفتاب “sun” + سوخته “burned” | sunburned/weathered by sun |
| modifier + verbal element | سختکوش | سخت “hard” + کوش “strive” | hard-working |
| possessive/exocentric | خوشقلب | خوش “good” + قلب “heart” | kind-hearted |
| possessive/exocentric | کمحرف | کم “little” + حرف “speech” | reserved, not talkative |
The English gloss often uses -ing, -ed, or -hearted, but Persian does not copy one English pattern. Meaning emerges from the particular compound and must be confirmed in actual usage.
Noun plus a verbal stem
Present stems are productive second elements in compounds. گیر comes from گرفتن “to take,” ساز from ساختن “to make,” and نشین from نشستن “to sit.” The first element supplies what is taken, made, or metaphorically sat in; the whole expression describes a property.
این فرایند خیلی وقتگیر است.
in farâyand kheyli vaqt-gir ast.
This process is very time-consuming. (neutral-formal)
یک اشکال کوچک میتواند در آینده مشکلساز شود.
yek eshkâl-e kuchak mi-tavânad dar âyande moshkel-sâz shavad.
A small defect can cause problems later. (formal-neutral)
موسیقی آرام فضای دلنشینی ایجاد کرده بود.
musiqi-ye ârâm fazâ-ye del-neshin-i ijâd karde bud.
The quiet music had created a pleasant atmosphere.
The internal elements do not form an ordinary phrase. وقتگیر is not pronounced vaqt-e gir, and دلنشین is not an ezâfe sequence “the heart of sitting.” Lexical stress and established spelling signal a word-level unit.
Noun plus participial material
Compounds with a past-participial element often describe a result caused by the first element: یخزده “frozen,” آفتابسوخته “sunburned,” دودگرفته “smoke-darkened/smoky.” Some remain transparent; others acquire conventional meanings.
میوههای یخزده را داخل این ظرف بگذار.
mive-hâ-ye yakh-zade râ dâkhel-e in zarf begozâr.
Put the frozen fruit in this container.
صورت آفتابسوختهاش نشان میداد مدت زیادی بیرون بوده است.
surat-e âftâb-sukhte-ash neshân mi-dâd moddat-e ziyâdi birun bude ast.
His sunburned face showed that he had been outdoors for a long time.
دیوار دودگرفته را دوباره رنگ کردند.
divâr-e dudgerefte râ dubâre rang kardand.
They repainted the smoke-darkened wall.
Spelling is not fully predictable from semantics. یخزده and آفتابسوخته visibly retain a ZWNJ boundary, while conventional compounds may be written solid. The dedicated Word Division in Compounds and Derivatives page explains the editorial principles; a dictionary remains necessary for individual words.
Possessive or “bahuvrihi” meanings
Some compounds describe an entity by a salient feature it possesses rather than naming the feature itself. خوشقلب literally evokes a good heart but describes a kind person; کمحرف describes someone who speaks little; سنگدل describes someone hard-hearted. Linguists call this an exocentric or bahuvrihi pattern: the referent is outside the literal compound head.
همسایهی جدیدمان آدم خوشقلبی است.
hamsâye-ye jadid-emân âdam-e khosh-qalb-i ast.
Our new neighbor is a kind-hearted person.
او در جلسه کمحرف بود، اما به همهچیز با دقت گوش داد.
u dar jalase kam-harf bud, ammâ be hame-chiz bâ deqqat gush dâd.
He was quiet in the meeting, but listened to everything carefully.
شخصیت سنگدل داستان حتی به خانوادهاش رحم نکرد.
shakhsiyyat-e sang-del-e dâstân hattâ be khânevâde-ash rahm nakard.
The hard-hearted character in the story did not spare even his family. (literary-neutral)
Literal translation can mislead here. سنگدل is not normally a geological description, just as English cold-hearted does not describe body temperature.
Ezâfe attaches outside the compound
When a compound adjective modifies a noun, the head noun takes ezâfe before the complete compound: پروژهی وقتگیر, کارمند سختکوش, چهرهی آفتابسوخته. The compound's internal boundary is not an ezâfe link.
کارمند سختکوش بخش فروش ارتقا یافت.
kârmand-e sakht-kush-e bakhsh-e forush erteqâ yâft.
The hard-working employee in the sales department was promoted. (formal-neutral)
پروژهی وقتگیر بالاخره تمام شد.
porozhe-ye vaqt-gir bâlâkhare tamâm shod.
The time-consuming project finally ended.
Predicatively, there is no ezâfe after the subject: پروژه وقتگیر است. This is the same attributive-predicative contrast as with a simple adjective.
این روش ساده است، اما وقتگیر است.
in ravesh sâde ast, ammâ vaqt-gir ast.
This method is simple but time-consuming. (predicative)
Plural invariance
A compound adjective does not take plural ها merely because its noun is plural. Compare دانشجوی سختکوش and دانشجوهای سختکوش: plurality is marked once on the noun, while the adjective keeps the same form.
دانشجوهای سختکوش زودتر کارشان را تحویل دادند.
dâneshju-hâ-ye sakht-kush zudtar kâr-eshân râ tahvil dâdand.
The hard-working students submitted their work earlier.
این مراحل وقتگیر است و باید سادهتر شود.
in marâhel vaqt-gir ast va bâyad sâde-tar shavad.
These stages are time-consuming and should be simplified. (formal inanimate singular agreement)
The singular copula with inanimate plural مراحل is a separate agreement pattern. It does not make وقتگیر singular; the adjective has no singular/plural opposition at all.
Productivity, register, and lexicalization
Compound adjectives are abundant in conversation, journalism, administration, and literature. Modern formal Persian readily creates technical items with productive elements such as ـساز “causing/making,” ـپذیر “capable of,” and ـمحور “centered on.” Yet acceptability is lexical and register-sensitive. A transparent innovation may be understandable without being the expression native speakers normally choose.
Spelling also records degrees of lexical unity imperfectly. Some compounds are solid, some use ZWNJ, and some remain separate phrases. There is no safe rule “all compounds get a half-space.” Learn spelling together with meaning and pronunciation.
A short dialogue
کدام برنامه را برای ثبت سفارش انتخاب کنیم؟
kodâm barnâme râ barâ-ye sabt-e sefâresh entekhâb konim?
Which program should we choose for recording orders?
برنامهی جدید کاربرپسندتر است، ولی کمی وقتگیر است.
barnâme-ye jadid kârbarpasand-tar ast, vali kami vaqt-gir ast.
The new program is more user-friendly, but it is a little time-consuming. (formal-neutral)
The compounds package complex descriptions efficiently, but they still occupy ordinary adjective positions.
Common Mistakes
1. Putting the compound adjective before its noun
❌ وقتگیر پروژه بالاخره تمام شد.
Incorrect neutral order — the complete compound adjective follows its noun.
✅ پروژهی وقتگیر سرانجام تمام شد.
porozhe-ye vaqt-gir sar-anjâm tamâm shod.
The time-consuming project eventually ended.
2. Inserting ezâfe inside a compound
❌ همکار سخت کوش امروز مرخصی است.
hamkâr-e sakht-e kush emruz morakhkhasi ast
Incorrect analysis — سختکوش is one compound adjective; it has no internal ezâfe.
✅ همکار سختکوش امروز مرخصی است.
hamkâr-e sakht-kush emruz morakhkhasi ast.
The hard-working colleague is off today.
3. Omitting the standard compound boundary
❌ این کار وقت گیر است.
Incorrect standard spelling for the established compound — write وقتگیر with a ZWNJ.
✅ این کار وقتگیر است.
in kâr vaqt-gir ast.
This task is time-consuming.
4. Pluralizing the adjective along with the noun
❌ دانشجوهای سختکوشها برنده شدند.
Incorrect — ها belongs on دانشجو; سختکوش remains invariant.
✅ دانشجوهای سختکوش برنده شدند.
dâneshju-hâ-ye sakht-kush barande shodand.
The hard-working students won.
5. Dropping outer ezâfe in pronunciation
❌ طرح مشکلساز را متوقف کردند.
tarh moshkel-sâz râ motavaqqef kardand
Incorrect reading — the noun طرح takes ezâfe before the compound adjective.
✅ طرح مشکلساز را امروز متوقف کردند.
tarh-e moshkel-sâz râ emruz motavaqqef kardand.
They stopped the problematic plan today.
Key Takeaways
- A compound adjective is internally complex but occupies one adjective slot.
- Noun + present stem compounds often express an effect; noun + participial compounds often express a resulting state.
- Possessive compounds such as خوشقلب describe a whole person through a salient feature.
- Ezâfe links the head noun to the complete compound, not the compound's internal elements.
- Compound adjectives remain invariant, and each established spelling must be learned rather than generated by one spacing rule.
