解析 بی اعتبار in your Level:
At the A1 level, you should understand that 'bi-e'tebar' means something is 'not good' or 'not working' because it is old or wrong. Think of it like a red 'X' on a paper. If you have a bus ticket from last year, it is 'bi-e'tebar.' It means you cannot use it. You don't need to use this word in your own speaking yet, but if a shopkeeper or a bus driver says it to you, they are telling you that your money, ticket, or card is not being accepted. It is a combination of 'bi' (no/without) and 'e'tebar' (credit/validity). Just remember: Bi-e'tebar = Not valid. For example, 'این پول بی اعتبار است' (This money is not valid/fake). It is a very useful word to recognize when you are traveling in Iran and dealing with documents or payments. You can simply associate it with the English word 'invalid' or 'expired.'

At the A2 level, you can start using 'bi-e'tebar' to describe simple things like expired food coupons, old ID cards, or rumors that you know are not true. You should be able to form simple sentences like 'کارت من بی اعتبار است' (My card is invalid). You are beginning to see that this word isn't just for objects; it can also be used for what people say. If a friend tells you something that sounds like a lie, you might think the news is 'bi-e'tebar.' You should also learn that its opposite is 'mo'tabar' (valid/reliable). In your studies, if you find a website that has wrong information, you can call it a 'website-e bi-e'tebar.' This level is about moving from just recognizing the word to using it as a basic adjective in your daily Persian vocabulary to describe the status of things around you.

You understand that this word carries a specific weight—it implies a loss of trust or legal power.

You can explain why a certain piece of news is 'bi-e'tebar' by saying 'چون منبع آن مشخص نیست' (because its source is not clear). At this level, you should be comfortable using the word in business contexts, like discussing a 'cheque bi-e'tebar' (bounced check), and in social contexts to describe someone who has lost their credibility due to their actions.
At the B2 level, you have a nuanced understanding of 'bi-e'tebar' and can use it in formal debates or written essays. You can distinguish it from synonyms like 'na-mo'tabar' (technical invalidity) and 'baatel' (legal nullification). You can use it to critique arguments, scientific theories, or political statements. For example, you might write: 'این نظریه به دلیل شواهد جدید بی اعتبار شده است' (This theory has been discredited due to new evidence). You also understand its use in media and journalism to describe 'discredited' figures or 'unverified' reports. You can handle the word in different registers, knowing that while it is a common word, it carries a professional and serious tone.

You might analyze how a legal system becomes 'bi-e'tebar' in the eyes of the public or how a historical document's 'e'tebar' is questioned by modern historians. Your usage is precise, and you can use derived forms and complex sentence structures involving the word. You understand the subtle emotional impact the word has when used in a rhetorical sense to delegitimize an idea or a person's life work.

You are also aware of the most obscure synonyms and antonyms and can choose between them to achieve specific stylistic effects.

بی اعتبار 30秒了解

  • Bi-e'tebar means 'invalid' or 'untrustworthy' in Persian.
  • It comes from 'bi' (without) and 'e'tebar' (credit/validity).
  • Commonly used for expired IDs, bounced checks, and fake news.
  • It can describe both physical documents and abstract human character.

The Persian word بی اعتبار (pronounced 'bi-e'tebar') is a sophisticated and highly versatile adjective used to describe something or someone that lacks credibility, validity, or a good reputation. At its linguistic core, it is a compound word formed by the prefix بی (bi), meaning 'without,' and the noun اعتبار (e'tebar), which translates to 'credit,' 'trust,' 'validity,' or 'prestige.' When combined, they create a powerful descriptor that spans various domains of life, from legal documents and financial instruments to personal integrity and scientific theories. In the context of daily life in Iran or among Persian speakers, you will encounter this word frequently in news broadcasts discussing the illegitimacy of certain claims, in business meetings regarding the expiration of contracts, or in social settings when discussing a person whose word can no longer be trusted. It is not merely a synonym for 'false'; rather, it implies that a previously held status of trust or legality has been lost or was never present to begin with. For instance, a passport that has passed its expiration date is بی اعتبار, not because it is a fake document, but because its legal power has ceased. Similarly, a rumor that has been debunked by experts is labeled بی اعتبار because it no longer carries the weight of truth. Understanding this word requires an appreciation for the cultural value placed on e'tebar (credit/honor) in Persian-speaking societies, where one's social standing is often tied to their perceived reliability.

Legal Context
In legal terminology, this word is used to describe contracts, signatures, or identification papers that are null and void. If a lawyer says a document is bi-e'tebar, it means it holds no weight in a court of law.
Financial Context
In banking, a 'cheque bi-e'tebar' refers to a bounced check or a check drawn on an account with insufficient funds, reflecting a lack of financial backing.
Social Context
When applied to a person, it suggests they have lost their 'face' or social capital. A person who lies consistently becomes bi-e'tebar in the eyes of their community.

این پاسپورت قدیمی به دلیل انقضا بی اعتبار شده است.

Translation: This old passport has become invalid due to expiration.

سخنان او در میان مردم بی اعتبار است.

Translation: His words lack credibility among the people.

چک بی اعتبار می‌تواند باعث مشکلات قانونی جدی شود.

Translation: An invalid (bounced) check can cause serious legal problems.

نظریات علمی قدیمی گاهی توسط کشفیات جدید بی اعتبار می‌شوند.

Translation: Old scientific theories are sometimes discredited by new discoveries.

امضای بدون مهر در این سازمان بی اعتبار محسوب می‌شود.

Translation: A signature without a stamp is considered invalid in this organization.

In summary, whether you are dealing with a faulty ID card, a politician's broken promise, or an unverified scientific claim, بی اعتبار is the essential term to express a lack of weight, truth, or legality. It carries a sense of formality but is also deeply embedded in the social fabric of trust and reputation in Persian culture.

Using بی اعتبار correctly in Persian involves understanding its role as an adjective that can describe both tangible objects and abstract concepts. Because it is a compound adjective, its placement in a sentence follows standard Persian grammatical rules. Most commonly, it appears after a noun connected by the 'Ezafe' (the short '-e' sound), or as a predicate at the end of a sentence. For intermediate learners (B1), the challenge lies in distinguishing when it means 'invalid' (legal/technical) versus 'untrustworthy' (moral/social). In formal writing, such as journalism or academic papers, it is often paired with verbs like دانستن (to consider) or خواندن (to call/label). For example, 'The committee considered the report invalid' translates to 'کمیته گزارش را بی اعتبار دانست'. In more colloquial settings, it is used with the simple verb بودن (to be) or شدن (to become). If you lose your credit card and it is deactivated, it becomes bi-e'tebar. If a friend tells a lie, their words become bi-e'tebar. Let's explore various sentence structures to master its application across different registers of the Persian language.

Attributive Usage
When modifying a noun directly: 'شایعات بی اعتبار' (Unreliable rumors). Here, the Ezafe links the noun 'rumors' to the adjective.
Predicative Usage
When acting as the main descriptor: 'این بلیط بی اعتبار است' (This ticket is invalid). This is the most common way to use the word in daily interactions.
Transitive Usage
Using verbs like 'to make invalid': 'او با دروغ‌هایش خود را بی اعتبار کرد' (He discredited himself with his lies).

تمام مدارک تحصیلی او بی اعتبار شناخته شدند.

Translation: All of his educational documents were recognized as invalid.

نباید بر اساس اطلاعات بی اعتبار تصمیم‌گیری کرد.

Translation: One should not make decisions based on unreliable information.

این قانون قدیمی اکنون کاملاً بی اعتبار است.

Translation: This old law is now completely invalid.

او سعی کرد رقیب خود را در رسانه‌ها بی اعتبار جلوه دهد.

Translation: He tried to make his rival appear discredited in the media.

اعتبارنامه‌ی سفیر به دلیل تنش‌های سیاسی بی اعتبار شد.

Translation: The ambassador's credentials became invalid due to political tensions.

To use بی اعتبار like a native, pay attention to the context. If you are talking about a broken machine, don't use it; use 'kharab' (broken). But if you are talking about the warranty on that machine being expired, بی اعتبار is the perfect choice. It denotes a loss of authority or trust rather than physical damage.

In the modern Persian-speaking world, بی اعتبار is a word that echoes through the halls of bureaucracy, the screens of digital media, and the conversations of the marketplace. One of the most common places you will hear this word is at a bank or a government office. If you present a document that is missing a necessary stamp or has expired, the clerk will likely say, 'این مدرک بی اعتبار است' (This document is invalid). Similarly, in the world of Iranian commerce, the phrase 'چک بی اعتبار' (invalid/bounced check) is a frequent and serious topic of discussion, often appearing in news reports about economic crimes or credit regulations. Beyond the world of paperwork, the word has seen a massive surge in usage on social media platforms like Instagram and Twitter (X). With the rise of 'fake news' and misinformation, Persian speakers use بی اعتبار to warn others about unverified sources or sensationalist headlines. You might see a comment on a viral post saying, 'این منبع بی اعتبار است، به آن اعتماد نکنید' (This source is unreliable, do not trust it). This usage highlights the word's role in the 'economy of trust' that defines modern digital interaction. Furthermore, in political discourse—whether on satellite TV news or in street-side debates—the word is used to attack the legitimacy of opponents' claims or the results of disputed processes. It is a sharp tool for delegitimization. Even in the realm of sports, a referee's controversial decision might be called بی اعتبار by frustrated fans or commentators. Finally, in more philosophical or literary discussions, you might hear older generations talk about the 'bi-e'tebari' of life, reflecting a traditional Persian worldview that the material world is fleeting and cannot be relied upon. This gives the word a depth that ranges from a simple 'void' stamp on a paper to a profound statement on the human condition.

News & Media
Broadcasters use it to describe discredited reports or international treaties that are no longer being honored.
Government Offices
Used by officials to inform citizens that their IDs, permits, or applications are not valid for processing.
Daily Shopping
A shopkeeper might use it if a discount code or a promotional coupon has expired.

گزارش‌های خبری نشان می‌دهند که این وب‌سایت بی اعتبار است.

Translation: News reports show that this website is unreliable/invalid.

متأسفم، کارت بانکی شما بی اعتبار شده است.

Translation: I am sorry, your bank card has become invalid.

Translation: In court, false testimony discredits the person.

این بلیت برای سفر امروز بی اعتبار است.

Translation: This ticket is invalid for today's travel.

او با رفتارهای عجیبش در خانواده بی اعتبار شد.

Translation: He lost his credibility in the family due to his strange behaviors.

Learning to use بی اعتبار effectively involves navigating several common pitfalls that English speakers and beginning Persian learners often encounter. The most frequent mistake is confusing بی اعتبار with other negative adjectives like بی ارزش (bi-arzesh), which means 'worthless' or 'valueless.' While something that is bi-e'tebar might indeed be worthless, the focus of bi-e'tebar is specifically on the lack of authority, trust, or legal validity. For example, a fake diamond is bi-arzesh (worthless), but a fake passport is bi-e'tebar (invalid). Another common error is using it to describe physical brokenness. You cannot say a chair is bi-e'tebar if its leg is broken; for that, you must use kharab or shekasteh. However, if the warranty for that chair has expired, the warranty itself is bi-e'tebar. Learners also sometimes struggle with the 'Ezafe' construction when using this word as an attribute. Remember that the 'e' sound must connect the noun to bi-e'tebar (e.g., 'sanad-e bi-e'tebar'). In terms of social usage, be careful not to use this word too lightly when referring to people. Calling someone bi-e'tebar is a serious accusation against their character and honor, similar to calling them a 'fraud' or 'untrustworthy' in a professional sense. It is much stronger than simply saying someone is 'wrong' (eshtebah). Finally, ensure you don't confuse it with نامعتبر (na-mo'tabar). While they are synonymous, na-mo'tabar is often preferred in highly technical or computer-related contexts (like an 'invalid password'), whereas bi-e'tebar has a broader, more traditional reach.

Mistaking for 'Worthless'
Incorrect: 'این ماشین بی اعتبار است' (meaning the car is cheap/worthless). Correct: Use 'bi-arzesh' for value and 'bi-e'tebar' for the car's registration if it's expired.
Incorrect Verb Pairing
Learners often forget that 'bi-e'tebar' is an adjective. Avoid using it as a verb without 'shodan' (to become) or 'kardan' (to make).
Overusing in Casual Settings
Don't use it for small mistakes. If a friend gets the time of a movie wrong, they aren't 'bi-e'tebar'; they are just 'eshtebah' (mistaken).

اشتباه: این صندلی بی اعتبار است چون پایه ندارد.

Correction: You should use 'kharab' (broken) here, not 'bi-e'tebar'.

درست: قرارداد به دلیل عدم امضا بی اعتبار است.

Usage: Correct use for a legal document lacking validity.

اشتباه: او یک آدم بی اعتبار است (Used for someone who just made a small mistake).

Correction: This is too strong; use 'bi-deghat' (careless) for small errors.

درست: شایعاتی که در تلگرام پخش می‌شوند اغلب بی اعتبار هستند.

Usage: Correct use for unreliable information/rumors.

اشتباه: من بی اعتبار کردم (Incomplete sentence).

Correction: Always specify what was discredited: 'من حرف او را بی اعتبار کردم'.

To truly master the Persian vocabulary, it is essential to understand how بی اعتبار relates to its synonyms and near-synonyms. While بی اعتبار is the most versatile term for 'invalid' or 'discredited,' other words offer more specific nuances depending on whether you are talking about law, logic, or personal character. For instance, نامعتبر (na-mo'tabar) is almost identical in meaning but carries a slightly more technical or administrative tone. You will see 'na-mo'tabar' on computer screens when you enter a wrong password or on a bank's website. On the other hand, بی‌پایه (bi-payeh), which literally means 'without a base/foundation,' is the best choice when describing baseless rumors or unfounded accusations. If you want to say a claim is completely false and fabricated, the word کذب (kezb) or دروغین (dorughin) is more appropriate. In legal contexts, you might also hear باطل (baatel), which specifically means 'void' or 'nullified,' often used for contracts or religious rituals that were not performed correctly. When discussing the lack of prestige or social standing, بی‌ارزش (bi-arzesh) focuses on the lack of value, while بی‌منزلت (bi-manzelat) focuses on the lack of status. Understanding these distinctions allows you to choose the word that fits the exact 'flavor' of invalidity you wish to express. Below is a comparison to help you navigate these choices.

بی اعتبار vs. نامعتبر
Bi-e'tebar: General, social, and legal. 'He is a discredited man.'
Na-mo'tabar: Technical and administrative. 'Invalid digital certificate.'
بی اعتبار vs. باطل
Bi-e'tebar: Focuses on lack of trust or expiration. 'Expired ID.'
Baatel: Focuses on being null/void by law or rule. 'A cancelled vote.'
بی اعتبار vs. بی‌پایه
Bi-e'tebar: The claim has no weight.
Bi-payeh: The claim has no evidence or foundation.

ادعای او کاملاً بی‌پایه و اساس است.

Translation: His claim is completely baseless and without foundation.

این بلیت سینما باطل شده است.

Translation: This cinema ticket has been voided/cancelled.

Translation: The entered password is invalid (Technical usage).

Translation: He gave false/fabricated information to the police.

小贴士

Prefix Power

Learn the 'bi-' prefix. It will help you unlock hundreds of Persian adjectives like 'bi-gonah' (innocent).

Reputation Matters

In Iran, 'e'tebar' is social currency. Use 'bi-e'tebar' carefully when talking about people.

Expired vs. Invalid

Use 'bi-e'tebar' for both. If a coupon is expired, it's bi-e'tebar.

Formal vs. Informal

For formal writing, use 'فاقد اعتبار' (faghed-e e'tebar).

News Keywords

'Bi-e'tebar' is a keyword in news about politics and economics. Listen for it!

Glottal Stop

Practice the 'ayin' sound in 'e'tebar' to sound more like a native speaker.

Compound Verbs

Remember to pair it with 'shodan' or 'kardan' to form complete thoughts.

Check the Source

When you see 'manba-e bi-e'tebar', it means 'unreliable source'. Very common today.

The Bank Rule

Associate 'bi-e'tebar' with a bank teller saying 'No' to your card.

Antonym Practice

Always learn 'mo'tabar' alongside 'bi-e'tebar' to double your vocabulary.

记住它

记忆技巧

Think of a 'BEE' (bi) flying away from a 'BAR' (e'tebar) of gold. The gold is no longer there, so the bar is 'invalid' and has no 'credit'.

视觉联想

Imagine a big red 'EXPIRED' or 'VOID' stamp hitting a document. That sound and visual is the essence of 'bi-e'tebar'.

Word Web

Invalid Expired Untrustworthy Bounced Check Fake News Void Discredited Null

挑战

Try to find three things in your house that are 'bi-e'tebar' (like an old receipt or an expired milk carton) and say 'In bi-e'tebar ast' out loud.

词源

A compound of the Persian prefix 'bi-' (without) and the Arabic loanword 'e'tebar' (credit/trust). The root of 'e'tebar' is the Arabic 'I-B-R', relating to crossing or interpreting.

原始含义： Lacking the quality of being trusted or crossing into the realm of acceptance.

Indo-European (Persian) + Afro-Asiatic (Arabic root).

文化背景

Be careful using this to describe a person's character; it is a strong term that can end a friendship or business relationship.

In English, we use different words: 'invalid' for IDs, 'unreliable' for news, and 'discredited' for people. Persian uses 'bi-e'tebar' for all of these.

Used in the poems of Hafez to describe the world. Frequent in Iranian legal codes regarding banking. Often heard in Iranian cinema when a character is betrayed.
