For example, if someone tells you a rumor that isn't true, you could say the information is غیرمعتبر. Or, if a ticket to an event isn't real, it's a بلیط غیرمعتبر (belit-e gheyr-e mo'tabar).
It's essentially the opposite of something being valid or credible.

For example, if a website gives you information that isn't true, you could say the information is غیرمعتبر. Or, if someone makes a promise they don't keep, you might consider them غیرمعتبر. It's a useful word for expressing doubt or a lack of confidence in something or someone.

§ What Does "غیرمعتبر" Mean?
- Definition
- Invalid, unreliable, discredited.
The Persian word "غیرمعتبر" (pronounced ghey-re mo'tabar) is a really useful term to know, especially when you're talking about things that aren't quite right, aren't trustworthy, or just don't hold up. Think of it as a go-to word for expressing that something lacks validity or credibility. It's not just for formal situations; you'll hear and use it in everyday conversations.
Let's break down its components a bit. The prefix "غیر-" (gheyre-) means "non-" or "un-". So, when you add it to "معتبر" (mo'tabar), which means "valid" or "credible," you get "non-valid" or "un-credible." Simple, right?
§ When Do People Use "غیرمعتبر"?
You'll find "غیرمعتبر" used in a variety of contexts. Here are some common scenarios:
- Invalid Information/Documents: If a document, a claim, or a piece of information isn't correct or doesn't meet the required standards, you'd use "غیرمعتبر."
- Unreliable Sources: When you're talking about news sources, reports, or even people whose information isn't trustworthy, "غیرمعتبر" fits perfectly.
- Discredited Arguments/Theories: In discussions or debates, if an argument or a theory has been proven wrong or is no longer accepted, it's considered "غیرمعتبر."
- Expired/Canceled Items: Sometimes, it can refer to things that are no longer active, like an expired coupon or a canceled membership, though there might be more specific words for these.
§ Examples in Use
این گواهینامه غیرمعتبر است.
This certificate is invalid.
اطلاعات ارائه شده غیرمعتبر بود.
The information provided was unreliable.
آن نظریه اکنون غیرمعتبر شناخته شده است.
That theory is now considered discredited.
As you can see from these examples, "غیرمعتبر" is quite versatile. It's a single word that can convey a strong sense of inaccuracy, untrustworthiness, or lack of official standing. Mastering this word will significantly boost your ability to express nuanced ideas in Persian, especially when discussing information, claims, or official matters. Keep practicing, and you'll be using it naturally in no time!
§ Understanding 'Gheyre Motabar'
When learning a new language, understanding how a word is used in different contexts is just as important as knowing its definition. The Persian word غیرمعتبر (gheyre motabar) is a great example. While its core meaning is 'invalid,' 'unreliable,' or 'discredited,' you'll encounter it in various situations, from formal news reports to everyday conversations about work or school. Let's break down where you're most likely to hear and use this word.
- DEFINITION
- Invalid, unreliable, discredited.
§ At Work: Unreliable Data and Invalid Documents
In a professional setting, you'll often hear غیرمعتبر when discussing information, documents, or data that cannot be trusted or are not officially recognized. Imagine you're in a meeting, and someone presents some findings. If the source of those findings is questionable, someone might say they are غیرمعتبر.
این آمار غیرمعتبر است و نمیتوانیم به آن تکیه کنیم. (This statistic is unreliable, and we cannot rely on it.)
You might also encounter it when dealing with official paperwork. If a document lacks the necessary signatures, stamps, or proper formatting, it could be deemed غیرمعتبر.
پاسپورت شما منقضی شده و غیرمعتبر است. (Your passport has expired and is invalid.)
This usage is very straightforward and essential for anyone working in an administrative or professional role in a Persian-speaking environment.
§ At School: Invalid Arguments and Discredited Theories
In academic settings, غیرمعتبر is frequently used to describe arguments, theories, or sources that lack proper evidence, logical reasoning, or have been disproven. When a student presents an argument that isn't well-supported, a teacher might describe it as غیرمعتبر.
استدلال او به دلیل نداشتن شواهد کافی غیرمعتبر بود. (His argument was invalid due to insufficient evidence.)
Similarly, if an old scientific theory has been replaced by newer, more accurate findings, it can be referred to as a نظریه غیرمعتبر (nazariye-ye gheyre motabar - discredited theory).
این نظریه علمی اکنون غیرمعتبر تلقی میشود. (This scientific theory is now considered discredited.)
This usage emphasizes the importance of credible sources and sound reasoning in academic discourse.
§ In the News: Unreliable Sources and Discredited Claims
News reports often deal with verifying information and sources. When a news outlet reports on a claim or a source that lacks credibility, they will use غیرمعتبر. This is crucial for maintaining journalistic integrity and informing the public about potentially misleading information.
این خبر از یک منبع غیرمعتبر منتشر شده است. (This news was published by an unreliable source.)
You might also hear it when a person's testimony or statement is questioned. If someone's past actions or inconsistencies make their current statements untrustworthy, they might be referred to as having اعتبار غیرمعتبر (e'tebar-e gheyre motabar - discredited credibility).
ادعاهای او غیرمعتبر شناخته شد. (His claims were found to be discredited.)
Understanding this usage will help you critically evaluate news reports and understand discussions about public figures.

How to Use It
When something is غیرمعتبر (gheyr-e mo'tabar), it means it's not valid, reliable, or trustworthy. You can use it to describe information, documents, or even sources.
For example, if a document has expired, you could say it's غیرمعتبر. If news is based on false information, you could also describe it as غیرمعتبر.

همکار گرامی، امیدوارم حال شما خوب باشد. در مورد روششناسی پیشنهادی شما برای پروژه، من معتقدم که این روش برای اهداف ما غیرمعتبر (unreliable) است. دادههای جمعآوری شده با این متد ممکن است نتایج قابل اعتمادی ارائه ندهند و اعتبار کلی تحقیق را زیر سوال ببرند. پیشنهاد میکنم به جای آن از روش مطالعه موردی با تجزیه و تحلیل کیفی عمیقتر استفاده کنیم تا به نتایج دقیقتری دست یابیم. با احترام، [نام شما]

موکل عزیز، در مورد مدارک ارائه شده توسط وکیل مقابل، میخواهم به شما اطمینان دهم که ما قصد داریم اعتبار آنها را به چالش بکشیم. بسیاری از این مدارک به دلیل عدم رعایت زنجیره حضانت یا جمعآوری غیرقانونی، از نظر قانونی غیرمعتبر (invalid) هستند. ما با ارائه اعتراضات رسمی و ارجاع به رویههای قانونی، بیاعتباری این شواهد را به دادگاه اثبات خواهیم کرد و مانع از استفاده آنها علیه شما خواهیم شد.
