قادر بودن

The Persian verb قادر بودن (ghāder budan) is a sophisticated, formal compound verb that translates to 'to be able' or 'to be capable.' While the common verb tavānestan (توانستن) is used in everyday conversation for general ability, ghāder budan elevates the discourse to a level of formal capacity, legal right, or physical/financial potential. It is derived from the Arabic root 'Q-D-R', which relates to power, measure, and destiny. In Persian, it functions as a compound verb consisting of the adjective 'قادر' (capable/powerful) and the auxiliary verb 'بودن' (to be). This word is not just about 'can'; it is about having the inherent agency or the external resources required to execute a specific action. When you use this word, you are often discussing significant achievements, legal possibilities, or the limits of human or technological potential.

Formal Capacity

Refers to an individual's or organization's official or legal ability to perform a task. For example, 'The court is able to issue a verdict.'

In academic writing, ghāder budan is preferred over tavānestan because it sounds more objective and precise. It suggests a state of being rather than just a simple action. For instance, instead of saying 'I can run,' which sounds like a physical act, one might say 'The system is capable of processing data,' which sounds like a functional specification. This distinction is crucial for C1 level learners who wish to sound professional. Furthermore, the verb is almost always followed by the preposition 'به' (be), which links the capability to the action or object. This grammatical structure is a hallmark of formal Persian syntax. Understanding the weight of this word allows a speaker to navigate high-level discussions in politics, science, and law with confidence.

Financial Means

Used to describe the ability to afford something or provide financial backing. 'He is not capable of paying the debt.'

The nuance of 'possibility' is also embedded here. While 'momken budan' (to be possible) describes the situation, 'ghāder budan' describes the agent's power within that situation. If a bridge is broken, you are not 'ghāder' to cross it, not because you lack the skill, but because the means are absent. This distinction between internal skill and external capacity is a recurring theme in classical Persian literature, where 'Qadr' often refers to the divine power of the Creator. In modern usage, however, it has been secularized to refer to human agency and technological power. Using this verb correctly signals to native speakers that you have moved beyond basic conversational Persian into the realm of intellectual and professional mastery. It is a word of empowerment and structural description.

Technological Specs

Used in manuals and tech reviews to describe what a machine or software can do. 'This software is capable of editing 4K video.'

Constructing sentences with قادر بودن requires attention to its unique grammatical requirements. Unlike the simple modal verb tavānestan, which takes a subjunctive verb directly, ghāder budan typically requires the preposition به (be) followed by either a noun, a gerund-like infinitive, or a subordinate clause introduced by که (ke). The most common structure in formal writing is: [Subject] + [Prepositional Phrase with 'به'] + [قادر بودن]. For example, 'او به تکلم به پنج زبان قادر است' (He is capable of speaking five languages). This structure places the emphasis on the capability itself rather than the action. It is essential to conjugate the auxiliary 'بودن' according to the tense: 'قادر هستم' (I am able), 'قادر بودم' (I was able), 'قادر خواهم بود' (I will be able).

When using the 'که' (ke) construction, the following verb must be in the subjunctive mood. This is a common pattern in contemporary Iranian media. For instance, 'دولت قادر نیست که تورم را مهار کند' (The government is not able to control inflation). Here, 'مهار کند' is the present subjunctive of 'مهار کردن'. This pattern is slightly more flexible and easier for learners who are already comfortable with the subjunctive. However, to achieve a truly 'C1' academic style, using the short infinitive or a noun after 'به' is recommended. For example, 'قادر به مهارِ تورم' (Capable of controlling inflation). This nominalization makes the sentence more compact and professional, a style frequently seen in reports and academic journals.

The 'Be' Preposition

The word 'قادر' (capable) almost always demands 'به' (to/of). Using it without 'به' is often considered grammatically incomplete in formal contexts.

In negative sentences, the particle 'نـ' (na) is attached to the auxiliary verb 'بودن', resulting in forms like 'قادر نیستم', 'قادر نبودیم', or 'قادر نخواهند بود'. Interestingly, in very formal or archaic styles, you might see 'ناقادر', but this is extremely rare in modern Persian and should generally be avoided in favor of the standard negative 'بودن'. Another important aspect is subject-verb agreement. Since 'ghāder' is an adjective, it does not change for plural subjects; only the 'budan' part changes. 'آن‌ها قادر هستند' (They are able), not 'آن‌ها قادران هستند'. This is a common point of confusion for students coming from languages where adjectives must agree in number with the noun they modify.

Finally, let's look at the future tense. In formal Persian, the future is constructed using 'خواه' + the short infinitive. Therefore, 'will be able' becomes 'قادر خواهد بود'. This is frequently used in political forecasting and strategic planning. For example, 'نیروهای امدادی تا ساعاتی دیگر قادر به دسترسی به منطقه خواهند بود' (Rescue forces will be able to access the area within a few hours). By mastering these various structures—prepositional, subjunctive, and future—you can express complex ideas about potential and capacity with the precision required for advanced communication.

You will encounter قادر بودن in environments where precision and formality are paramount. One of the primary locations is the evening news (Akhbar). News anchors in Iran use this verb when discussing international relations, government capabilities, or economic indicators. For example, a report might state that 'ایران قادر به تولید انرژی هسته‌ای است' (Iran is capable of producing nuclear energy). The choice of ghāder budan here conveys a sense of national strength and technical achievement that the simpler tavānestan would lack. It frames the ability as a permanent state or a significant milestone rather than a mundane action.

Legal Documents

Contracts often use this to define what a party is authorized or able to do. 'The tenant is not able to sublet the property.'

Another common setting is the academic lecture or scientific seminar. Professors use this verb to describe the properties of elements, the functions of the brain, or the limits of mathematical models. In these contexts, ghāder budan functions as a technical term. For instance, 'This algorithm is capable of identifying patterns.' It moves the conversation from human 'doing' to systemic 'capability.' If you are reading a Persian translation of a philosophy book or a scientific journal, you will see this word on almost every page. It is essential for discussing agency (fa'eliyat) and potentiality (ghovve), which are central themes in both classical and modern Persian intellectual thought.

In the business world, ghāder budan is found in corporate reports, mission statements, and job descriptions. A company might state that it is 'capable of meeting all client needs.' In a job interview, a candidate might say 'من قادر به مدیریت تیم‌های بزرگ هستم' (I am capable of managing large teams) to sound more professional and authoritative than if they used the colloquial 'mitunam.' Furthermore, the word appears frequently in religious and spiritual contexts. In Islamic theology, God is often referred to as 'Al-Qadir' (The All-Powerful). In Persian prayers and sermons, you will hear descriptions of how only God is ghāder to perform miracles or forgive all sins. This religious undertone gives the word a certain gravity and solemnity even when used in secular contexts.

Literature and Poetry

Modern Persian poets use the word to explore the limits of language and the human condition. 'Language is not able to describe your beauty.'

One of the most frequent mistakes learners make with قادر بودن is misusing the preposition. Many students, influenced by the structure of tavānestan, try to use it without be (به). For example, saying 'Man ghāder hastam beram' (I am able I go) is grammatically incorrect. It must be 'Man ghāder be raftan hastam' or 'Man ghāder hastam ke beram.' Forgetting the 'be' is a clear sign of a lower proficiency level. Another common error is treating 'ghāder' as a verb that can be conjugated on its own. It is an adjective; only the 'budan' part changes. You cannot say 'ghāderid' for 'you are able'; you must say 'ghāder hastid'.

Register Mismatch

Using 'ghāder budan' in a casual conversation with friends about simple tasks (like buying bread) sounds incredibly stiff and unnatural, almost like a robot.

Another subtle mistake involves the distinction between ghāder budan and tavānestan in terms of 'permission.' In English, 'can' can mean both 'ability' and 'permission.' In Persian, tavānestan can occasionally lean toward permission in informal settings, but ghāder budan NEVER means permission. It strictly refers to capacity or power. If you ask 'Are you able to enter?' using ghāder budan, you are asking if they have the physical or legal strength to break in or pass through, not if they have the host's permission. Confusing these can lead to awkward misunderstandings in social or legal settings.

Word order can also be a challenge. In formal Persian, the object of the ability often comes before the verb. A learner might say 'Man ghāder hastam be pardākht-e pool,' but a more natural formal order is 'Man be pardākht-e pool ghāder hastam.' While the first isn't strictly wrong, the second shows a better grasp of Persian literary rhythm. Additionally, learners often forget the 'ezafe' when using nouns after 'be'. For example, 'ghāder be anjām-e kar' (capable of doing the work). Forgetting the 'e' in 'anjām-e' makes the phrase sound disjointed and unprofessional. Mastery of these small details is what separates a B2 learner from a C1 expert.

Pluralization Error

Do not pluralize 'ghāder' to 'ghāderān' when the subject is plural. It remains 'ghāder' regardless of the subject's number.

To truly enrich your Persian vocabulary, you must understand the spectrum of words related to 'ability.' The most direct synonym is توانستن (tavānestan). This is the 'workhorse' verb of the language. It is used in 90% of situations where you want to say 'can' or 'to be able.' It is less formal and much more versatile than ghāder budan. Another close relative is توانا بودن (tavānā budan). While ghāder focuses on the capacity to do something specific, tavānā is more of a character trait, meaning 'to be powerful' or 'to be capable' in a general, often heroic sense. It is common in poetry and epic literature like the Shahnameh.

ghāder vs. tavānestan

Ghāder is formal, academic, and often requires 'be'. Tavānestan is neutral, common, and functions as a modal verb.

In professional and legal contexts, you might encounter استطاعت داشتن (estetā'at dāshtan). This specifically refers to financial capability. If you have the 'estetā'at' to go on Hajj, it means you have the money and health to do so. Similarly, بضاعت داشتن (bezā'at dāshtan) is used for financial or intellectual resources. If a company has no 'bezā'at', it means it lacks the capital to undertake a project. On the other hand, مقدور بودن (maghdur budan) is used to say something is 'possible' or 'feasible.' Instead of saying 'I am able to come,' you might say 'It is not possible (maghdur) for me to come,' which is a very polite and common way to decline an invitation in formal Persian.

For describing high-level expertise, the word قابلیت داشتن (ghābelyat dāshtan) is useful. It translates to 'having the potential' or 'having the capability.' It is often used for objects or systems: 'This car has the capability (ghābelyat) to reach high speeds.' Finally, there is یارایِ چیزی را داشتن (yārā-ye chizi rā dāshtan), a very literary and poetic way to say 'to have the strength or daring to do something.' It is often used in the negative: 'I did not have the strength (yārā) to speak.' By choosing the right word from this list, you can express the exact nature of the ability you are describing, from simple 'can' to divine 'omnipotence'.

estetā'at vs. ghāder

Estetā'at is almost exclusively financial or health-related. Ghāder is broad and general capability.
