解析 بی کیفیت in your Level:

At the A1 level, you only need to know that 'bi-keyfiyat' means 'bad quality' for things you buy. It is the opposite of 'khub' (good) or 'ba-keyfiyat' (good quality). You can use it in very simple sentences like 'In kafsh bi-keyfiyat ast' (This shoe is low-quality). Think of it as a way to say 'I don't like this product because it is not well-made.' It's a useful word for basic shopping and traveling. You don't need to worry about complex grammar yet; just focus on the basic meaning of 'not good quality.'

At the A2 level, you can start using 'bi-keyfiyat' with the Ezafe construction to describe nouns directly. For example, 'ghaza-ye bi-keyfiyat' (low-quality food). You can use it to talk about common everyday items like clothes, food, or toys. You should also be able to understand it when a shopkeeper or a friend uses it to warn you about a product. You might use it with intensifiers like 'kheyli' (very) to say 'این کیف خیلی بی کیفیت است' (This bag is very low-quality). It helps you express simple opinions about the world around you.

At the B1 level, you should be comfortable using 'bi-keyfiyat' in more varied contexts, such as describing services, digital media, or work performance. You can use it to complain politely but firmly. For example, 'Man az in khadamat-e bi-keyfiyat razi nistam' (I am not satisfied with this low-quality service). You should also understand its role in consumer culture in Iran and be able to distinguish it from 'arzan' (cheap). You can start using it in written reviews or in discussions about why you prefer one brand over another. It becomes a tool for expressing more nuanced dissatisfaction.

At the B2 level, you can use 'bi-keyfiyat' to discuss broader social and economic issues. You might talk about the 'bi-keyfiyati' (noun form) of certain industries or the impact of 'bi-keyfiyat' materials on safety. You should be able to use synonyms like 'namorgub' in formal settings and 'ashghal' in very informal ones. You can use the word to critique art, literature, or film, explaining *why* the quality is low (e.g., poor script, bad acting). Your sentences will become more complex, using the word in subordinate clauses or as part of a larger argument about standards.

At the C1 level, you use 'bi-keyfiyat' with precision and stylistic flair. You understand the subtle difference between 'bi-keyfiyat' and 'faghed-e estandard' or 'namorgub.' You can engage in high-level debates about the decline of quality in modern manufacturing or the philosophical implications of a 'low-quality' lifestyle. You can use the word ironically or metaphorically in literature or high-level journalism. You are also aware of the historical and etymological roots of the word and can use its noun and verb derivatives (like 'bi-keyfiyat kardan') fluently in academic or professional discussions.

At the C2 level, you have a near-native command of 'bi-keyfiyat.' You can sense the emotional weight the word carries in different Persian-speaking regions. You can use it in complex rhetorical structures and understand its nuances in classical-style modern prose. You can distinguish between the 'bi-keyfiyat' of a product and the abstract 'lack of quality' in a political system or an educational curriculum. You can write extensive critiques using this term as a thematic anchor, and you can navigate the most heated arguments in a bazaar or a boardroom using this word and its synonyms with perfect cultural appropriateness.

بی کیفیت 30秒了解

Means 'low-quality' or 'substandard'.
Formed from 'bi' (without) + 'keyfiyat' (quality).
Used for products, services, and work output.
Common in shopping, reviews, and daily complaints.

The Persian word بی کیفیت (bi-keyfiyat) is a compound adjective that serves as a cornerstone for describing the standard of objects, services, and even abstract concepts. At its core, it translates to 'low-quality' or 'poor-standard.' The word is formed by the prefix بی- (bi-), meaning 'without' or 'un-', and the noun کیفیت (keyfiyat), which means 'quality.' Therefore, it literally signifies something that lacks quality. In the modern Iranian marketplace and social discourse, this term is ubiquitous. Whether you are complaining about a cheap pair of shoes that fell apart after two days, a blurry video on YouTube, or a meal at a restaurant that lacked flavor and fresh ingredients, بی کیفیت is your go-to descriptor.

Morphology: The prefix 'bi-' is one of the most productive prefixes in Persian, used to create privative adjectives. Combining it with 'keyfiyat' (an Arabic loanword for quality) creates a clear, unambiguous term for substandard goods.

من هرگز این مارک بی کیفیت را دوباره نمی‌خرم.
(I will never buy this low-quality brand again.)

Beyond physical objects, the term is frequently applied to services and digital media. In the era of high-definition streaming, Iranians often use this word to describe a slow internet connection that results in a 'low-quality' image. It carries a heavy connotation of disappointment and frustration. When someone calls something بی کیفیت, they aren't just saying it's 'bad'; they are saying it fails to meet the expected or professional standard of its category. It is the opposite of باکیفیت (ba-keyfiyat), which means high-quality.

Social Context: In Iranian consumer culture, there is a strong emphasis on 'jens' (material/goods). Labeling a product as 'bi-keyfiyat' is a serious critique that can damage a seller's reputation instantly.

فیلم‌های این جشنواره بسیار بی کیفیت بودند.
(The movies in this festival were of very poor quality.)

In a professional setting, a manager might describe a report or a piece of code as بی کیفیت to indicate that it requires significant revision. It implies a lack of attention to detail or a lack of resources during production. Interestingly, while the word is objective in its literal meaning, its usage is often deeply subjective, reflecting the speaker's personal expectations of what 'quality' should look like. In modern Persian slang, you might also hear people use more colorful terms like 'ashghal' (trash), but بی کیفیت remains the standard polite yet firm way to express dissatisfaction with standards.

Usage Frequency: The word is extremely common in online reviews (like on Digikala, the Iranian Amazon) and in daily conversations about inflation and the declining standard of goods.

Using بی کیفیت in a sentence follows the standard Persian rules for adjectives. Most commonly, it follows the noun it modifies, connected by the Ezafe vowel (-e or -ye). For example, 'low-quality food' becomes ghaza-ye bi-keyfiyat. It can also function as a predicate adjective after verbs like 'to be' (budan) or 'to become' (shodan). Understanding its placement is key to sounding natural. Because it is a multi-syllabic compound word, it carries a certain weight in the sentence, often being the focal point of the speaker's frustration.

Common Pattern 1: Noun + Ezafe + Adjective: This is the attributive use. Example: پارچه‌ی بی کیفیت (Low-quality fabric).

او همیشه لباس‌های بی کیفیت می‌پوشد.
(He always wears low-quality clothes.)

When used as a predicate, the word describes the subject of the sentence. This is very common in reviews and complaints. You might say, 'This phone's screen is low-quality.' In Persian: Safhe-ye in gushi bi-keyfiyat ast. Notice how the adjective doesn't change for gender or number, as Persian adjectives are generally invariant. However, you can add intensifiers like خیلی (kheyli - very) or بسیار (besyar - extremely) before it to emphasize just how poor the quality is.

Common Pattern 2: Subject + Adjective + Verb: This is the predicative use. Example: این عکس بی کیفیت است (This photo is low-quality).

In more complex sentences, بی کیفیت can be used to compare two things. While the comparative form بی کیفیت‌تر (bi-keyfiyat-tar) exists, speakers often prefer to say 'quality is lower' (keyfiyatash payin-tar ast). However, in casual speech, saying 'This one is more low-quality' is perfectly acceptable. It is also used in the negative to defend a product: 'It's not low-quality!' (Bi-keyfiyat nist!). This versatility makes it an essential tool for any intermediate learner navigating Iranian markets or digital spaces.

چرا اینقدر کارهای بی کیفیت ارائه می‌دهی؟
(Why do you present such low-quality work?)

Formal vs Informal: In formal writing, you might see 'faghed-e keyfiyat' (lacking quality), but 'bi-keyfiyat' is the standard for both spoken and standard written Persian.

You will encounter بی کیفیت in a variety of real-world scenarios in Iran. One of the most common places is the **Bazaar** or modern shopping malls. Shoppers often whisper this to their companions when inspecting the stitching of a garment or the material of a plastic toy. It's a word of caution. If a vendor hears you calling their product bi-keyfiyat, they might quickly try to show you a better version or justify the price by saying 'Well, it's cheap!' (Arzan ast!).

The Digital World: On Iranian social media (Instagram, Telegram), users often complain about 'bi-keyfiyat' internet speeds or 'bi-keyfiyat' content produced by influencers only looking for clicks.

این ویدیو خیلی بی کیفیت است؛ هیچی معلوم نیست.
(This video is very low-quality; nothing is visible.)

Another major arena for this word is **Customer Support**. If an Iranian calls a service provider to complain about a faulty appliance or a bad repair job, بی کیفیت is the central complaint. It's used in formal emails of protest and in heated phone calls. In the automotive industry, which is a frequent topic of public debate in Iran, people often criticize domestic cars as being bi-keyfiyat compared to international standards. This has turned the word into a bit of a political and economic buzzword, symbolizing the struggle for better manufacturing standards.

The Culinary Scene: In restaurants, if the rice is overcooked or the meat is tough, a patron might tell the manager that the food was 'bi-keyfiyat' to explain why they won't be returning.

Finally, you'll hear it in **Academic and Professional** settings. A professor might critique a student's paper as being bi-keyfiyat in terms of its research sources. In the construction industry, engineers might warn about bi-keyfiyat cement or steel that could compromise a building's safety. In all these contexts, the word serves as a marker of standard-testing. It is rarely used for people's character (you wouldn't call a person 'bi-keyfiyat'), but it is used for the *output* of people—their work, their products, and their services.

ساختمان‌ها به دلیل مصالح بی کیفیت فرو ریختند.
(The buildings collapsed due to low-quality materials.)

News & Media: Headlines often read: 'Preventing the distribution of low-quality medicines' (Jologiri az tozih-e daru-haye bi-keyfiyat).

One of the most frequent mistakes English speakers make when using بی کیفیت is confusing it with the general word for 'bad' (bad). While all bi-keyfiyat things are 'bad' in a sense, not all 'bad' things are bi-keyfiyat. For example, if someone is mean to you, they are a 'bad person' (adam-e bad), but you would never call them an 'adam-e bi-keyfiyat.' Bi-keyfiyat is strictly reserved for the standard of production, performance, or material. Using it for human character sounds very strange and robotic.

Mistake 1: Misapplying to People: Don't say: 'دوستم بی کیفیت است' (My friend is low-quality). Say: 'دوستم اخلاق بدی دارد' (My friend has a bad character).

Incorrect: این مرد بی کیفیت است.
Correct: این کالا بی کیفیت است.

Another common error involves the Ezafe. Learners often forget to add the 'e' or 'ye' sound between the noun and the adjective. Forgetting this makes the sentence sound like a list of words rather than a cohesive thought. For instance, saying 'ghaza bi-keyfiyat' instead of 'ghaza-**ye** bi-keyfiyat' is a hallmark of beginner speech. Additionally, some learners try to pluralize the adjective when describing plural nouns. In Persian, adjectives stay singular even if the noun is plural (e.g., 'kafsh-haye bi-keyfiyat' - low-quality shoes).

A third mistake is using بی کیفیت when the speaker actually means 'cheap' (arzan). While they often go hand-in-hand, they are different concepts. Something can be cheap but high-quality (arzan vali ba-keyfiyat). If you tell a seller something is 'bi-keyfiyat' just because the price is low, you might be wrong. Always check the material first! Lastly, avoid using it to describe weather. You wouldn't say 'the weather is low-quality'; you would say 'the weather is bad' (hava bad ast) or 'the air is polluted' (hava aludeh ast).

Mistake 2: Missing Ezafe: Always connect the noun: 'لباسِ بی کیفیت' (Lebas-e bi-keyfiyat).

Incorrect: این فیلم بی کیفیت بود.
Correct: این فیلمِ بی کیفیت بود. (Or: این فیلم بی کیفیت بود as a predicate is fine!)

While بی کیفیت is the most common term, Persian offers several alternatives depending on the level of formality and the specific type of 'low quality' you are describing. Understanding these nuances will help you sound more like a native speaker and allow you to express precise levels of dissatisfaction.

Paeen (Low): Instead of 'bi-keyfiyat,' you can say 'ba keyfiyat-e paeen' (with low quality). This is slightly more formal and descriptive.
Namorgub (Substandard): This is a very formal, technical word often used in trade and law. You'll see it on packaging or in official reports.
Ashghal (Trash/Junk): This is slang. If a product is so bad it's useless, Iranians call it 'ashghal.' Use this only with friends.

این جنس نامرغوب است و نباید فروخته شود.
(This substandard material should not be sold.)

Another useful word is الکی (alaki), which means 'fake' or 'flimsy.' If a toy breaks immediately because it wasn't made properly, you might call it 'alaki.' For food, you might use بدمزه (bad-mazeh - bad tasting) if the quality issue is specifically about the flavor. If you are talking about a person's work specifically, سرِ هم بندی (sar-e-ham-bandi) refers to something 'thrown together' or 'slapped together' without care. This is a great idiomatic way to describe low-quality labor.

Faghed-e Estandard (Lacking Standards): Used when a product fails to meet safety or industry regulations.

کار این تعمیرکار واقعاً سرِ هم بندی بود.
(This repairman's work was really just slapped together.)

In summary, choose your word based on your audience. In a shop, stick to bi-keyfiyat. In a legal document, use namorgub. When venting to a sibling about a broken phone, ashghal is the way to go. By mastering these synonyms, you show a deeper grasp of Persian social dynamics and the importance of quality in the culture.

How Formal Is It?

The root 'kayf' in Arabic is also the source of the word 'Kief' (cannabis resin) and the Turkish word 'Keyif' (pleasure/leisure), though in 'keyfiyat' it strictly refers to the 'nature' or 'quality' of a thing.

Always remember the 'e' sound: 'Kala-ye bi-keyfiyat'. Without it, you sound like a robot.

Prefix Power

Learn the 'bi-' prefix. It will help you understand hundreds of other words like 'bi-adab' (rude) and 'bi-pool' (penniless).

Sound Like a Native

Use 'vaghe'an' (really) before 'bi-keyfiyat' when you are complaining. It adds emotional weight.

Bargaining

Calling an item 'bi-keyfiyat' in a bazaar is a classic move to get a lower price, but don't be too rude!

Context Matters

If you hear 'keyfiyat' followed by 'payin' (low), it's the same as 'bi-keyfiyat'.

Reviews

When writing a review on Digikala, use 'bi-keyfiyat' to describe the material and 'bad' to describe the overall experience.

Made in...

Iranians often associate 'bi-keyfiyat' with certain cheap imports. Be aware of this bias.

Digital Quality

Use it for low-res photos! 'In aks bi-keyfiyat ast' is perfect for a blurry picture.

The 'Bi' Trick

Think of 'Bi' as 'Below' quality. It starts with B and means something is under the standard.

Arabic Roots

Knowing that 'keyfiyat' comes from 'how' helps you remember it's about the 'nature' of the item.

记忆技巧

Think of a 'Bee' (بی) that is 'Kept' (کیف) in a 'Yacht' (یت) that is falling apart. A 'Bee-Kept-Yacht' is definitely low-quality!

视觉联想

Imagine a bright red 'X' over a broken, gray, pixelated smartphone. The word 'BI-KEYFIYAT' is written in big letters across the screen.

Word Web

Bi-keyfiyat Arzan (Cheap) Ashghal (Trash) Kharab (Broken) Namorgub (Substandard) Bad (Bad) Bi-arzesh (Worthless) Alaki (Flimsy)

挑战

Go to an online Iranian store (like Digikala) and find three reviews where people use the word 'بی کیفیت'. Translate what they are complaining about.

词源

A hybrid Persian-Arabic compound. 'Bi' is a prefix from Middle Persian 'be' meaning 'without'. 'Keyfiyat' is an Arabic loanword formed from 'kayf' (how) and the suffix '-iyat' (abstract noun maker), literally meaning 'how-ness'.

原始含义： The state of lacking a specific nature or standard.

Indo-European (Persian) + Semitic (Arabic loanword).

文化背景

Avoid using it to describe traditional crafts (like carpets) in front of the weaver, as it can be taken as a deep personal insult.

Similar to saying 'cheaply made' or 'shoddy' in English, but more common in everyday speech.

常见问题

10 个问题

No, it's not natural. To call someone 'low quality' in character, use 'adam-e bad' or 'bi-shakhsiyat' (lacking personality/class). Using 'bi-keyfiyat' for a person sounds like you are describing them as a manufactured product.

Yes, it is a neutral and polite way to express that a product is not good. It's much more polite than saying 'ashghal' (trash).

The most common opposite is 'ba-keyfiyat' (high-quality) or 'ba-keyfiyat-e bala'.

It is spelled as 'بی کیفیت' (B-Y-K-Y-F-Y-T). Sometimes it's written with a half-space: 'بی‌کیفیت'.

Absolutely. It's very common to describe food in a bad restaurant as 'ghaza-ye bi-keyfiyat'.

In Persian, adjectives do not change for plural nouns. So 'kafsh-haye bi-keyfiyat' is correct, not 'bi-keyfiyat-ha'.

'Kharab' means broken or out of order. 'Bi-keyfiyat' means it was poorly made, even if it's currently working.

Yes, it is professional enough for meetings, though 'namorgub' is even more formal.

No. For bad weather, use 'hava-ye bad' or 'hava-ye aludeh' (polluted air).

Yes, it is one of the top 2000 most useful words in modern Persian due to consumer culture.
