解析 کم‌بازده in your Level:

At the A1 level, the word 'kam-bāzdeh' is quite advanced. You don't need to use it yet, but it's helpful to know that 'kam' means 'little' or 'small'. Think of it like this: 'kam' (little) + 'bāzdeh' (the result you get back). If you play a game and get only one point, that is a 'kam' result. For now, just remember that 'kam' is the opposite of 'ziyād' (a lot). You will mostly use 'kam' for things like 'kam āb' (little water) or 'kam ghazā' (little food). This word is a special kind of 'kam' for when you work hard but get very little back. It's a professional way of saying 'not much'.

At the A2 level, you are starting to learn compound words. 'Kam-bāzdeh' is a compound adjective. 'Kam' is 'little' and 'bāzdeh' is 'yield' or 'result'. You might hear this word on the news in Iran when they talk about money or farming. You can use it to describe a battery that doesn't last long: 'In bāteri kam-bāzdeh ast' (This battery is low-yield/inefficient). It's a more grown-up way of saying 'it's not very good'. Try to recognize it in sentences about work or business. It always follows the noun it describes, using the 'e' sound (Ezafe).

At the B1 level, you should begin incorporating 'kam-bāzdeh' into your vocabulary when discussing work, productivity, or economics. Instead of saying 'in kār sud-e kami dārad' (this work has little profit), you can say 'in kār kam-bāzdeh ast' (this work is low-yield). This makes your Persian sound more natural and professional. You should understand that it's often used for systems, like 'system-e ābyāri' (irrigation system) or 'niru-gāh' (power plant). It implies that resources are being wasted. You can also use it to describe study habits if you aren't learning efficiently.

You should distinguish it from synonyms like 'gheyr-e kār-āmad' (inefficient) or 'bi-bahreh' (fruitless). At this level, you should also be comfortable with its opposite, 'por-bāzdeh' (high-yield). You should use the 'nim-fāseleh' (half-space) when writing it. It's an evaluative word that shows you can analyze the relationship between input (money, time, energy) and output (profit, results, crops).

At the C1 level, you should use 'kam-bāzdeh' with precision in academic or professional writing. You should understand its nuances in different domains—for example, the difference between a 'kam-bāzdeh' investment in the stock market versus a 'kam-bāzdeh' educational curriculum. You can use it to critique complex systems. You should also be familiar with related terms like 'bāzdehi' (productivity/yield rate). Your usage should reflect an understanding of the word's formal register and its role in technical discourse. You might use it in a sentence like: 'Structural inefficiencies have rendered the state-owned sectors increasingly kam-bāzdeh.'

کم‌بازده 30秒了解

Kam-bāzdeh means low-yield or inefficient, describing something that gives back very little result.
It is a compound of 'kam' (little) and 'bāzdeh' (return/yield).
It is commonly used in business, farming, and technical contexts in Iran.
It is a formal word, essential for B2-level Persian learners to sound professional.

The Persian word کم‌بازده (pronounced 'kam-bāzdeh') is a sophisticated compound adjective used primarily in economic, agricultural, and technical contexts to describe something that produces a low return on investment, effort, or resources. It is composed of two distinct parts: kam (کم), meaning 'little' or 'low', and bāzdeh (بازده), which translates to 'yield', 'output', or 'return'. In a literal sense, it describes a system or process where the 'giving back' (output) is significantly less than the input provided. This word is essential for B2-level learners because it transitions them from basic descriptors like 'bad' or 'little' into the professional and academic vocabulary required for discussing efficiency and productivity.

Economic Context: In finance, it refers to assets or investments that provide minimal profit. For example, a savings account with a 0.1% interest rate is considered a sarmāye-gozāri-ye kam-bāzdeh (a low-yield investment).
Agricultural Context: It describes land or crops that do not produce much harvest despite being cultivated. Soil that lacks nutrients is often described as khāk-e kam-bāzdeh.

سرمایه‌گذاری در این بخش بسیار کم‌بازده است و ریسک بالایی دارد.

Translation: Investing in this sector is very low-yield and carries high risk.

Understanding کم‌بازده requires an appreciation for the Persian suffix -deh, which comes from the present stem of the verb dādan (to give). Thus, bāzdeh is literally 'giving back'. When we add kam, we are describing a situation where the world, the market, or the machine is 'giving back very little'. It is not necessarily 'useless' (bi-fāyedeh), but rather 'inefficient'. This nuance is crucial; a kam-bāzdeh factory still works, but it wastes energy or money relative to its output.

چرا از این روش کم‌بازده برای تولید برق استفاده می‌کنید؟

Industrial Usage: Refers to machinery or energy sources that have low efficiency, such as old coal plants compared to modern solar panels.

In modern Iranian discourse, this term often appears in critiques of state-run industries or outdated educational systems. When a critic calls a university department kam-bāzdeh, they are suggesting that despite the funding and students, the research output or job placement rates are unacceptably low. It is a word of evaluation and critique, weighing the 'input' against the 'result'.

Using کم‌بازده correctly involves placing it after a noun using the Ezafe construction (the short 'e' sound connecting a noun to its adjective). Because it is a compound adjective, it remains stable and does not usually change form. It functions exactly like other adjectives such as bozorg (big) or gerān (expensive), but carries a heavy semantic weight regarding productivity.

بسیاری از چاه‌های نفت در این منطقه کم‌بازده شده‌اند.

Translation: Many of the oil wells in this region have become low-yield.

In this example, the word describes a physical resource. Note how it follows the verb shodan (to become). You can also use it to describe abstract concepts like 'time' or 'efforts'. If you spend five hours studying but only learn two words, you might describe that session as yek jalase-ye motāle-eye kam-bāzdeh.

Sentence Structure 1: Noun + Ezafe + Adjective: Example: Zamin-e kam-bāzdeh (Low-yield land). Here, the -e after Zamin connects it to the adjective.
Sentence Structure 2: Subject + Adjective + Verb 'to be': Example: In dāru kam-bāzdeh ast (This medicine is low-efficacy/low-yield). Note: while 'low-yield' is the primary meaning, in some contexts it implies low effectiveness.

دولت باید از حمایت واحدهای تولیدی کم‌بازده دست بردارد.

Translation: The government should stop supporting low-yield production units.

When discussing human behavior, kam-bāzdeh can be slightly insulting if applied to a person's performance. It suggests that the person is not providing enough value relative to their salary or position. However, it is more commonly applied to 'systems' or 'methods' rather than individual people directly, which would often use tanbal (lazy) or bi-kefāyat (incompetent) instead.

نیروگاه‌های قدیمی بسیار کم‌بازده هستند و سوخت زیادی مصرف می‌کنند.

You will encounter کم‌بازده most frequently in formal Iranian media, such as news broadcasts on IRIB, economic journals like Donya-e-Eqtesad, and in academic settings. It is a staple of 'Business Persian'. If you are listening to a podcast about the Iranian economy, you will hear experts debating why certain sectors remain kam-bāzdeh despite heavy subsidies.

گزارش‌ها نشان می‌دهد که بخش کشاورزی در مناطق خشک بسیار کم‌بازده شده است.

Translation: Reports show that the agricultural sector in arid regions has become very low-yield.

In a corporate environment, a manager might use this word during a performance review of a project. They might say, 'This marketing strategy is kam-bāzdeh,' meaning the amount of money spent on ads isn't bringing in enough new customers. It sounds much more objective and professional than saying 'the ads are bad'.

News Media: Used to describe the stock market (bourse) on days when returns are minimal. 'Bāzār-e kam-bāzdeh' (A low-yield market).
Environmental Discussions: Used to describe inefficient energy consumption. 'Lāmp-hā-ye kam-bāzdeh' (Low-efficiency bulbs/incandescent bulbs).

تعویض خودروهای کم‌بازده با مدل‌های برقی یک ضرورت است.

Socially, you might hear it in conversations between educated adults discussing their investments or the state of the country. It is less common in 'street slang' or among children, who would prefer simpler words like 'kharāb' (broken/bad) or 'kam' (little). If you use this word in a casual setting, it signals that you have a high level of education and a good grasp of formal Persian vocabulary.

One of the most frequent mistakes English speakers make is confusing کم‌بازده with kam-arzesh (low-value). While they are related, they are not the same. Something can be high-value but kam-bāzdeh. For example, a diamond ring is high-value, but as an investment, it might be kam-bāzdeh because its price doesn't increase quickly over time.

اشتباه: این کتاب کم‌بازده است. (Correction: This book is low-yield? Usually, we mean 'low quality' or 'boring'.)

Another mistake is using it to mean 'lazy' for people. You should not say 'Man kam-bāzdeh hastam' to mean 'I am feeling lazy today'. Instead, use bi-hoseleh (unmotivated) or tanbal. Kam-bāzdeh describes the *result* of your work, not your personality trait.

Mistake 1: Confusing with 'Useless': Incorrect: In kelid kam-bāzdeh ast (This key is low-yield). Correct: In kelid kharāb ast (This key is broken). Keys don't have 'yields'.
Mistake 2: Spelling/Spacing: Incorrect: Writing it as two separate words with a full space (کم بازده). In modern Persian, compound adjectives should use the 'nim-fāseleh' (zero-width non-joiner) to show they are a single concept.

درست: سیستم آبیاری کم‌بازده باعث هدررفت آب می‌شود.

Finally, ensure you don't confuse bāzdeh (yield) with bāzdid (visit). They look similar but have completely different meanings. A kam-bāzdid website has few visitors, while a kam-bāzdeh website fails to convert visitors into customers.

Depending on the context, you might want to use a different word to express inefficiency or low return. Persian has a rich set of synonyms that vary in formality and specific application. Understanding these will help you choose the right word for the right situation.

بی‌بهره (Bi-bahreh): Means 'fruitless' or 'without benefit'. It is more absolute than kam-bāzdeh. While kam-bāzdeh means low return, bi-bahreh implies zero return or being deprived of something.
کم‌سود (Kam-sood): Specifically refers to financial profit. Use this for a business deal that didn't make much money. Kam-bāzdeh is broader and can apply to energy or soil, whereas kam-sood is strictly about money.
غیرکارآمد (Gheyr-e Kār-āmad): Means 'inefficient' or 'ineffective'. This is the closest academic synonym. It focuses on the 'method' being wrong, while kam-bāzdeh focuses on the 'result' being small.

این پروژه کم‌سود بود، اما تجربه خوبی برای ما شد.

Comparison: Here 'kam-sood' focuses on the money, whereas 'kam-bāzdeh' would focus on the overall output.

In casual speech, Iranians might simply say be dard nakhor (doesn't work/useless) or za'if (weak). For example, kārash za'ifeh (his work is weak/unproductive). However, in a professional report, kam-bāzdeh is the gold standard.

بخش کشاورزی سنتی در این منطقه کاملاً غیرکارآمد است.

Remember that 'kam-' acts like a prefix. Once you learn 'kam-bāzdeh', you can easily learn 'kam-hush' (low intelligence) or 'kam-rang' (pale/low color).

Opposites Attract

Always learn 'kam-bāzdeh' alongside 'por-bāzdeh'. This doubling of vocabulary helps cement the concept of 'bāzdeh' (yield) in your mind.

Business Persian

If you work in Iran or with Iranians, use this word in reports. It shows you understand the technical nuances of productivity.

The Nim-fāseleh

On a Persian keyboard, the half-space is usually Shift+Space. Using it in 'کم‌بازده' makes your writing look professional.

News Keywords

When you hear 'eqtesād' (economy), listen for 'kam-bāzdeh'. They are frequent partners in news stories.

Soft 'H'

Practice the ending '-deh'. It should sound like a soft exhale at the end of the word.

Resource Awareness

Iran faces water and energy shortages. Words like 'kam-bāzdeh' are central to discussions about saving resources.

The Return

Focus on 'bāz' (back). If you get 'little back', you have 'kam-bāz-deh'.

Farming First

If you're stuck, think of a farm. A farm with no tomatoes is 'kam-bāzdeh'. Apply that logic to money or energy.

Level Up

Using this word correctly is a sign you've moved past the 'Intermediate' plateau into 'Advanced' territory.

词源

A modern Persian compound. 'Kam' comes from Middle Persian 'kam' (small/little). 'Bazdeh' is a compound of 'baz' (back/again) and 'deh' (the present stem of 'dadan', to give).

原始含义： Literally 'giving back little'.

Indo-European (Persian).

文化背景

Calling a person 'kam-bāzdeh' is professional but can be seen as cold or overly critical in a social setting. Use it for systems, not personalities.

In English, we might use 'inefficient' or 'unproductive' more broadly, whereas 'kam-bāzdeh' is very specific to the 'return' on something.

Economic reports by the Central Bank of Iran. Agricultural studies on the Urmia Lake basin. Speeches regarding the privatization of the 'Bourse' (Stock Market).

常见问题

10 个问题

It's technically possible but sounds like you're treating them as a machine or an economic unit. It's better to use 'kam-kār' (low-working) or 'tanbal' (lazy). If you say a person is 'kam-bāzdeh', you are specifically critiquing their professional output relative to their cost.

They are very similar. 'Na-kār-āmad' means 'inefficient' or 'ineffective'—the system doesn't work well. 'Kam-bāzdeh' specifically focuses on the 'yield' (the result). A system might be 'kār-āmad' (efficient) but 'kam-bāzdeh' because the resource itself is limited.

Yes, it is almost always used critically to describe something that isn't performing as well as it should. It implies disappointment or a need for change.

The opposite is 'por-bāzdeh' (پر بازده). You just swap 'kam' (little) for 'por' (full/much).

Usually, no. For a movie, you'd say it's 'boring' or 'bad'. You might use it for a book if you mean 'this book didn't teach me much for the time I spent reading it', but even then, it's very formal.

Yes, 'kam-bāzdehi' (کم‌بازدهی) means 'the state of being low-yield' or 'low productivity'.

Yes, if it follows a noun. For example: 'Zamin-e kam-bāzdeh'. If it's at the end of the sentence like 'In zamin kam-bāzdeh ast', you don't need the Ezafe.

Only if you are discussing serious topics like work, money, or the news. It's not a word you'd use to describe your dinner or a walk in the park.

Rarely. You wouldn't say a person's health is 'kam-bāzdeh'. You might say a 'treatment' or 'diet' is 'kam-bāzdeh' if it's not producing results.

No, but it is very soft. It's like the 'h' in 'yeah' but slightly more pronounced. Don't drop it completely.
