الشرح کارآیی داشتن in your Level:

At the A1 level, the concept of 'efficiency' (کارآیی داشتن) is quite advanced. However, you can think of it as a way to say something 'works very well.' Instead of just saying 'good' (خوب), you use this word for machines or tools. For example, if your computer is fast and helps you do your homework quickly, it has 'کارآیی.' You don't need to conjugate it in complex ways yet; just remember that 'کارآیی دارد' means 'it works efficiently.' Focus on the 'کار' part of the word, which you already know means 'work.' This word tells you how the 'work' is 'coming' along. In A1, we usually stick to simple adjectives, but knowing this word will make you sound like a much more serious student of Persian. Just remember: it's not for people being 'nice,' it's for things or methods being 'useful' and 'fast.'

At the A2 level, you can start using 'کارآیی داشتن' in simple sentences about your daily life and tools. You might use it to describe your new phone or a study method. For instance, 'این اپلیکیشن برای یادگیری لغات کارآیی خوبی دارد' (This app has good efficiency for learning words). At this stage, you should be comfortable with the present tense 'دارد' and the past tense 'داشت.' You are beginning to move beyond basic descriptions and starting to evaluate how things function. You can also start to use the negative form 'کارآیی ندارد' to complain about a broken tool or a bad plan. Remember to keep 'کارآیی' as one block and only change the 'داشتن' part. It's a great way to start sounding more professional when you talk about your work or school projects.

By B1, you should understand 'کارآیی داشتن' as a standard part of discussing productivity and technology. You can use it to compare two things. For example, 'ماشین‌های برقی کارآیی بیشتری نسبت به ماشین‌های بنزینی دارند' (Electric cars have more efficiency compared to gasoline cars). You should be able to use it with adverbs like 'بسیار' (very), 'کمی' (a little), or 'واقعاً' (really). At this level, you are also expected to understand it when you hear it in news clips or read it in simple articles about the environment or economy. You're starting to see it as a 'functional' word rather than just a 'useful' word. It's also a good time to learn the noun 'ناکارآمدی' (inefficiency) as its opposite. This will help you express more complex opinions in discussions about social issues or business.

At the B2 level, which is where this word is officially categorized, you should have a nuanced understanding of 'کارآیی داشتن.' You should be able to distinguish it from 'موثر بودن' (effectiveness) and use it in formal contexts like business meetings or academic essays. You should be comfortable with complex sentence structures, such as using it in the subjunctive: 'امیدوارم این تغییرات کارآیی داشته باشند' (I hope these changes will be efficient). You should also be able to use it to describe abstract concepts like 'کارآییِ بازار' (market efficiency) or 'کارآییِ سیستم آموزشی' (efficiency of the educational system). At this stage, you are not just using the word; you are using it to analyze and critique. You should be able to explain *why* something has or doesn't have 'کارآیی' using supporting arguments in Persian.

At the C1 level, 'کارآیی داشتن' becomes a tool for high-level analysis. You should be able to use it in professional reports, scientific discussions, and literary critiques. You might explore the philosophical or economic implications of 'کارآیی' in a society. For example, you could discuss the 'کارآیی تخصیصی' (allocative efficiency) in an economics paper. You should also be familiar with related formal terms like 'بازدهی' (yield/efficiency) and 'بهره‌وری' (productivity) and know exactly when to use each. Your usage should be flawless, including the correct use of prepositions and Ezafe. You might also use the word in a metaphorical sense in literature or high-level journalism to describe the 'efficiency' of a poet's use of language or the 'efficiency' of a political movement's strategy.

At the C2 level, your mastery of 'کارآیی داشتن' is indistinguishable from that of an educated native speaker. You can use it in any register, from highly technical engineering specifications to abstract philosophical debates. You understand the historical evolution of the term and how it fits into the broader Persian lexicon of work and utility. You can use it with subtle irony or within complex rhetorical devices. You are also capable of translating technical documents that involve 'efficiency' metrics, ensuring that 'کارآیی داشتن' is used correctly in place of 'efficacy,' 'efficiency,' or 'utility' depending on the specific scientific context. You can lead a seminar or write a thesis in Persian where 'کارآیی' is a central theme, discussing its nuances across different industries and historical periods.

کارآیی داشتن في 30 ثانية

A B2-level compound verb meaning 'to be efficient' or 'to have utility' in professional and technical contexts.
Used to describe machines, systems, and human productivity by emphasizing the ratio of output to input.
Grammatically, 'کارآیی' remains static while 'داشتن' is conjugated as the auxiliary verb.
Essential for academic, business, and news-related Persian, often compared with 'effectiveness' and 'productivity'.

The Persian compound verb کارآیی داشتن (pronounced as kār-āyī dāštan) is a cornerstone of professional, academic, and technical discourse in Iran. At its core, it translates to 'to be efficient' or 'to have utility.' However, the nuance goes much deeper than a simple dictionary definition. It describes the ratio of output to input, the ability of a machine to perform without wasting energy, or the capacity of an individual to produce high-quality results within a specific timeframe. In modern Persian, this word has gained significant traction in the fields of management, engineering, and economics, where 'efficiency' is a measurable metric of success.

Technical Application: In engineering, it refers to the performance of a motor or a system. For example, when discussing a new solar panel, an engineer would say it has high 'کارآیی' because it converts more sunlight into electricity compared to older models.
Human Resources and Productivity: In a corporate setting, a manager might evaluate an employee's performance by looking at how much 'کارآیی' they have. It isn't just about working hard; it is about working smart and achieving goals with the least amount of wasted effort.
General Utility: In everyday life, a tool or a method that works well is said to have 'کارآیی.' If a new kitchen gadget actually saves you time, it has 'کارآیی داشتن' in that specific context.

این موتور جدید در مقایسه با مدل قبلی، کارآیی بیشتری دارد و سوخت کمتری مصرف می‌کند.
— This new engine has more efficiency compared to the previous model and consumes less fuel.

When you use this word, you are signaling a level of sophistication in your vocabulary. It is not a word usually taught in the first few weeks of Persian class because it deals with abstract concepts of performance. However, for anyone looking to work in Iran or read Persian news, understanding 'کارآیی داشتن' is essential. It is frequently paired with adverbs like 'بسیار' (very) or 'کم' (little) to quantify the level of effectiveness.

روش‌های سنتی آموزش دیگر برای دانش‌آموزان امروزی کارآیی ندارند.
— Traditional teaching methods no longer have efficiency (are no longer effective) for today's students.

Understanding the difference between 'کارآیی داشتن' (efficiency) and 'موثر بودن' (effectiveness) is key for B2 learners. While 'موثر بودن' means getting the job done, 'کارآیی داشتن' emphasizes getting the job done with the best possible use of resources. In a Persian business meeting, if you want to suggest that a process is wasteful, you would say it lacks 'کارآیی' (کارآیی لازم را ندارد).

Economic Context: Economists use this term to describe market efficiency (کارآیی بازار). A market has 'کارآیی' when prices reflect all available information.
Biological Context: In biology, the 'کارآیی' of an organ or a metabolic process refers to how well it sustains life using the energy provided by nutrients.

Using کارآیی داشتن correctly requires understanding its role as a compound verb where 'داشتن' is conjugated according to the subject and tense. Because 'کارآیی' is a noun functioning as the non-verbal element, it remains static while 'داشتن' changes. Below, we explore various grammatical structures and contexts to master its usage.

Present Continuous Usage: When describing a system currently in operation, we use the present tense. 'این سیستم در حال حاضر کارآیی خوبی دارد.' (This system currently has good efficiency.)
Negative Constructions: To say something is inefficient, you simply negate the auxiliary verb: 'کارآیی نداشتن'. 'این دارو برای بیماری من کارآیی نداشت.' (This medicine did not have efficiency/effectiveness for my illness.)

برای افزایش کارآیی سازمان، باید فرآیندها را بازنگری کنیم.
— To increase the efficiency of the organization, we must review the processes.

In formal writing, you will often see 'کارآیی داشتن' paired with intensive adjectives. Phrases like 'کارآیی فوق‌العاده‌ای داشتن' (to have extraordinary efficiency) or 'کارآیی حداقلی داشتن' (to have minimal efficiency) are common in reports. It is also important to note that in Persian, we often use the preposition 'در' (in) or 'برای' (for) to specify the domain of efficiency.

آیا این استراتژی در بازارهای بین‌المللی کارآیی خواهد داشت؟
— Will this strategy have efficiency in international markets?

When discussing personal skills, one might say: 'او در مدیریت زمان کارآیی بالایی دارد.' (He has high efficiency in time management.) Here, 'کارآیی داشتن' acts as a predicate describing a trait. In more advanced Persian, you might encounter the causative form or passive-like structures, though 'داشتن' itself is rarely made passive; instead, nouns like 'بهره‌وری' might be used.

Let's look at the conditional usage. 'اگر بودجه بیشتری داشتیم، این پروژه کارآیی بیشتری می‌داشت.' (If we had a larger budget, this project would have had more efficiency.) This shows how 'داشتن' follows standard Persian conjugation rules even when part of this specific compound verb. Furthermore, in the plural, we don't usually pluralize 'کارآیی'; we say 'کارآییِ سیستم‌ها' (the efficiency of the systems) rather than 'کارآیی‌های'.

Scientific Reports: 'نتایج آزمایش نشان داد که واکسن کارآیی ۹۰ درصدی دارد.' (The test results showed that the vaccine has 90% efficiency/efficacy.)
Educational Context: 'معلمان باید روش‌هایی را انتخاب کنند که بیشترین کارآیی را برای یادگیری داشته باشند.' (Teachers should choose methods that have the most efficiency for learning.)

If you are walking down a street in Tehran, you might not hear 'کارآیی داشتن' in a casual conversation about the weather. However, the moment the conversation shifts to electronics, cars, or work, this word becomes ubiquitous. It is a 'high-register' word that has successfully migrated into the daily vocabulary of the middle class and professionals.

در اخبار اقتصادی: 'دولت برای بهبود کارآییِ بخش خصوصی برنامه‌های جدیدی دارد.'
— In economic news: 'The government has new plans to improve the efficiency of the private sector.'

One of the most common places to hear this word is on Iranian television news, specifically during the 'Pāyesh' (Monitoring) programs or economic segments. Journalists use it to critique government spending or to praise new technological breakthroughs. When a new dam is inaugurated, the reporter will invariably mention its 'کارآیی' in managing water resources.

In the Office: You will hear this during performance reviews. A boss might say, 'کارآیی شما در این فصل عالی بود' (Your efficiency this quarter was excellent). It is a professional way to give feedback without being too personal.
In University Lectures: Whether it's a class on thermodynamics, psychology, or political science, professors use 'کارآیی داشتن' to discuss the functionality of models and theories. It is a staple of academic Persian.

Interestingly, you will also hear this word in advertisements. Iranian tech companies often market their apps by claiming they increase the 'کارآیی' of your smartphone or your business operations. An ad for a banking app might say, 'با اپلیکیشن ما، مدیریت مالی شما کارآیی بیشتری خواهد داشت' (With our application, your financial management will have more efficiency).

Lastly, in the medical field, doctors and researchers use it when discussing the 'efficacy' of treatments. In Persian medical journals, 'کارآیی بالینی' (clinical efficiency/efficacy) is a standard term used to describe how well a drug works in a controlled environment. If you are watching a documentary about health on the 'Salamat' channel, you will hear this word multiple times an hour.

Mastering 'کارآیی داشتن' involves avoiding several common pitfalls that even intermediate learners often fall into. The most frequent errors involve confusing it with similar-sounding words or using the wrong preposition.

Mistake 1: Confusing 'کارآیی' with 'کاربرد': Many learners say 'این ابزار کارآیی‌های زیادی دارد' when they mean 'this tool has many uses.' In this case, 'کاربرد' (usage) is the correct word. 'کارآیی' is about how well it works, not what it is used for.
Mistake 2: Using 'کردن' instead of 'داشتن': Because many Persian verbs use 'کردن' (to do/make), learners often say 'کارآیی کردن.' This is incorrect. Efficiency is something a system has (داشتن), not something it does.

Incorrect: این برنامه کارآیی کرد.
Correct: این برنامه کارآیی داشت.

Another subtle mistake is failing to use the Ezafe correctly when adding adjectives. Learners might say 'کارآیی خوب داشتن' instead of 'کارآییِ خوب داشتن.' The 'i' sound (Ezafe) is crucial to connect the noun 'کارآیی' to its quality. Furthermore, in spoken Persian, some might shorten 'کارآیی' to 'کارایی' (kār-ā-yi), but in formal writing, the 'آ' (alef-ba-kolah) is traditionally maintained to show the long 'ā' sound clearly.

In terms of register, using 'کارآیی داشتن' in a very casual setting (like talking to a child about their toys) might sound overly formal or even sarcastic. For simple things that 'work well,' Iranians often just say 'خوب کار می‌کنه' (It works well). Save 'کارآیی داشتن' for when you want to sound precise, professional, or analytical.

Mistake 3: Over-pluralization: Avoid saying 'کارآیی‌ها.' Efficiency is usually treated as an uncountable concept in Persian. If you need to talk about different types of efficiency, use 'انواع کارآیی' (types of efficiency).

While 'کارآیی داشتن' is a powerful term, Persian offers several synonyms and related words that can add variety to your speech and writing. Depending on the context—whether it's economic, physical, or general—you might choose a different word to be more precise.

بهره‌وری (Bahre-vari): Often translated as 'productivity.' While 'کارآیی' is about the quality of the process, 'بهره‌وری' is more about the output. In business, these are often used together: 'افزایش کارآیی و بهره‌وری' (increasing efficiency and productivity).
موثر بودن (Mo'asser budan): This means 'to be effective.' If a medicine cures a headache, it is 'موثر.' If it cures the headache using only a tiny dose with no side effects, it has 'کارآیی.'
مفید بودن (Mofid budan): A more general term meaning 'to be useful.' This is the everyday version of 'کارآیی داشتن.' You would use this for a helpful book or a good piece of advice.

Comparison:
1. این روش مفید است. (This method is useful.)
2. این روش کارآیی بالایی دارد. (This method has high efficiency.)

In technical contexts, you might also encounter 'راندمان' (Randemān), which is a loanword from French ('rendement'). It is used almost exclusively in engineering and physics to describe the efficiency of machines (e.g., 'راندمان موتور'). If you are talking about a car engine, 'راندمان' and 'کارآیی' are interchangeable, but 'کارآیی' is more common in management and social sciences.

To describe something that is totally lacking in efficiency, you can use 'بی‌فایده' (useless) or 'ناکارآمد' (inefficient/incapable). 'ناکارآمد' is the direct adjectival antonym of 'کارآیی داشتن.' A government that cannot provide services is described as 'دولت ناکارآمد.' Understanding these nuances will help you navigate professional Persian environments with ease.

نصائح

Context Matters

Use 'کارآیی داشتن' when you want to sound like an expert or a professional. It carries more weight than 'خوب بودن'.

The Ezafe

Don't forget the 'ye' sound (Ezafe) when saying 'کارآییِ بالا'. It's essential for correct Persian grammar.

Synonym Choice

If talking about a car engine, try using 'راندمان' to sound even more like a native engineer.

Formal Reports

In business reports, always use 'افزایش کارآیی' instead of 'بهتر کردن کار'.

Pronunciation

Make sure to pronounce the 'yī' at the end clearly; don't let it fade away.

News Keywords

This is a 'keyword' in Persian economic news. When you hear it, focus—the speaker is making an evaluation.

Work-Ability

Think: Kār (Work) + Āyī (Ability/Coming). The ability for work to come through.

Modern Iran

Understand that 'efficiency' is a major topic in modern Iranian discourse due to economic factors.

No 'Kardan'

Never say 'کارآیی کرد'. It's always 'کارآیی داشت'.

Professionalism

Using this word in a job interview in Iran will significantly impress your employers.

احفظها

وسيلة تذكّر

Think of 'Car-Ah-Yee'. A 'Car' that is 'Ah!' (great) and 'Yee!' (fast) has 'kār-āyī' (efficiency).

ربط بصري

Visualize a high-speed train moving perfectly on its tracks without any smoke or noise. That is 'کارآیی داشتن'.

تحدٍّ

Try to describe three things in your room that 'کارآیی دارند' and one thing that 'کارآیی ندارد' using full Persian sentences.

أصل الكلمة

A modern Persian compound. 'Kār' comes from Middle Persian 'kār', from Old Persian 'kāra' (people/army/work). 'Āyī' is the nominal suffix derived from 'āmadan' (to come).

المعنى الأصلي: Literally 'the coming of work' or 'the ability for work to happen.'

Indo-European -> Indo-Iranian -> Iranian -> Western Iranian -> Persian.

السياق الثقافي

No specific sensitivities; it is a neutral, professional term.

English speakers often use 'effective' and 'efficient' interchangeably, but in Persian, 'کارآیی' is strictly 'efficient'.

Used frequently in the 'Bist-o-Chahar' (24) news program on IRIB. Common in the writings of Iranian economists like Mousa Ghaninejad. A key term in the 'Tehran Municipality' development plans.

الأسئلة الشائعة

10 أسئلة

Yes, they are the same word. The version with 'آ' is more formal and technically correct in Persian typography to represent the long 'ā' sound, but 'کارایی' is very common in digital typing.

Yes, but it sounds professional. You would use it in a performance review. For a friend, you'd usually say 'زرنگ' (smart/quick) or 'پرکار' (hardworking).

The most direct opposite is 'ناکارآمد بودن' or simply 'کارآیی نداشتن'.

It is very common in news, work, and when discussing technology, but less common in casual family dinners unless discussing something like a new appliance.

You say 'کارآییِ انرژی' (kār-āyī-ye eneržī).

Technically yes (کارآیی‌ها), but it is almost always used as an uncountable noun in Persian.

Usually 'در' (in) or 'برای' (for). Example: کارآیی در تولید (efficiency in production).

Rarely. It is a modern, technical word. Classical poetry uses words like 'سعی' (effort) or 'همت' (resolve).

Yes, in medical contexts, 'کارآییِ بالینی' means clinical efficacy.

No, that is a common mistake. You must use 'داشتن' (to have).
