- A prefix meaning 'against' or 'resistant to'.
- Forms words like 'waterproof' and 'antiviral'.
- Indicates opposition or protection.
- Commonly used in product descriptions and medicine.
The Persian prefix 'ضد' (zed) is a powerful tool for creating words that describe resistance or opposition. Think of it like the English prefixes 'anti-' or '-proof'. It's used to indicate that something is designed to prevent, counteract, or be unaffected by something else.
You'll encounter 'ضد' in many everyday contexts. For instance, when talking about materials, you might hear about 'ضد آب' (zed-āb), meaning waterproof, or 'ضد زنگ' (zed-zang), meaning rustproof. In a medical context, 'ضد ویروس' (zed-virus) refers to antiviral, and 'ضد درد' (zed-dard) means painkiller. It can also be used more abstractly, like 'ضد انقلاب' (zed-enghelāb), meaning counter-revolutionary.
The prefix 'ضد' is highly productive in Persian, allowing for the creation of new terms as needed. Its clear meaning makes it easy to understand the core concept of the word it modifies. When you see 'ضد' attached to another word, you can almost always infer that the new word describes something that stands against or protects from the meaning of the second word.
Consider the word 'ضد گلوله' (zed-guloole), which means bulletproof. This clearly illustrates the protective nature implied by the prefix. Similarly, 'ضد عفونی' (zed-ofuni) means disinfectant, highlighting its role in combating germs. The prefix adds a layer of specificity and functionality to the base word, making it an essential part of the Persian vocabulary for describing protective qualities and oppositional stances.
The versatility of 'ضد' extends to describing behaviors or attitudes. For example, 'ضد اجتماعی' (zed-ejtemā'i) describes someone who is antisocial. This shows how the prefix can be used to denote a lack of conformity or an opposition to societal norms. Understanding 'ضد' opens up a vast array of vocabulary related to protection, resistance, and opposition in the Persian language.

این پارچه ضد آب است.
او یک پزشک ضد ویروس است.
Using 'ضد' (zed) in sentences is straightforward once you grasp its core meaning of opposition or resistance. It typically attaches directly to a noun or an adjective to create a new word that specifies a protective or counteracting quality. The resulting word then functions as a single unit within the sentence.
For instance, to say 'This phone is waterproof,' you would combine 'ضد' with 'آب' (āb - water) to form 'ضد آب' (zed-āb) and then use it as an adjective: 'این تلفن ضد آب است' (In telefon zed-āb ast). Here, 'ضد آب' describes the phone.
Similarly, if you want to talk about a 'bulletproof vest,' you would use 'ضد' with 'گلوله' (guloole - bullet) to create 'ضد گلوله' (zed-guloole): 'او یک جلیقه ضد گلوله پوشیده بود' (Ou yek jaligeh zed-guloole pushideh bood - He was wearing a bulletproof vest). The phrase 'ضد گلوله' acts as an adjective modifying 'جلیقه' (vest).
In more abstract or medical contexts, the structure remains the same. For an 'antiviral medicine,' you combine 'ضد' with 'ویروس' (virus) to get 'ضد ویروس' (zed-virus): 'داروی ضد ویروس بسیار مؤثر بود' (Dāru-ye zed-virus besyār mo'asser bood - The antiviral medicine was very effective). Here, 'ضد ویروس' functions adjectivally to describe the medicine.
You can also use 'ضد' to express opposition to concepts or movements. For example, 'anti-war' is 'ضد جنگ' (zed-jang). A sentence could be: 'آنها یک تظاهرات ضد جنگ برگزار کردند' (Ānhā yek tazāhorāt-e zed-jang bargozār kardand - They organized an anti-war demonstration). In this case, 'ضد جنگ' modifies 'تظاهرات' (demonstration).
The key is to remember that 'ضد' is almost always a prefix, meaning it comes before the word it modifies, and together they form a new descriptive term. The grammatical function of the combined word (usually an adjective or noun) will dictate its placement in the sentence, just like any other adjective.
Let's look at another example: 'fireproof'. This is 'ضد حریق' (zed-harigh). 'این ساختمان ضد حریق ساخته شده است' (In sākhtemān zed-harigh sākhteh shodeh ast - This building has been constructed fireproof). The pattern is consistent: prefix + noun = new descriptive term.
Even when expressing a negative sentiment towards something, like 'anti-social,' the prefix works the same way: 'ضد اجتماعی' (zed-ejtemā'i). 'رفتار او ضد اجتماعی بود' (Raftār-e ou zed-ejtemā'i bood - His behavior was antisocial).
- Structure
- Prefix + Noun/Adjective = New Word (usually adjective)
- Example 1
- ضد (zed) + آب (āb) = ضد آب (zed-āb) - Waterproof
- Example 2
- ضد (zed) + گلوله (guloole) = ضد گلوله (zed-guloole) - Bulletproof
این لباس ضد حریق است.

You'll hear the prefix 'ضد' (zed) frequently in various aspects of Iranian life and culture. Its prevalence stems from its utility in describing practical features, medical treatments, and even social or political stances.
In everyday conversations about products and materials, 'ضد آب' (zed-āb - waterproof) and 'ضد لک' (zed-lak - stain-resistant) are common. When shopping for clothing, outdoor gear, or even electronics, you'll often see these terms advertised. Similarly, 'ضد زنگ' (zed-zang - rustproof) is a key feature for metals and vehicles.
The medical field is another major area where 'ضد' is ubiquitous. Doctors and patients discuss 'داروهای ضد ویروس' (dāruhā-ye zed-virus - antiviral drugs), 'آنتیبیوتیکهای ضد باکتری' (antibiotik-hā-ye zed-bākteri - antibacterial antibiotics), and 'کرمهای ضد آفتاب' (kerm-hā-ye zed-āftāb - sunscreens). You might also hear about 'واکسنهای ضد فلج اطفال' (vāksenhā-ye zed-felj-e atfāl - polio vaccines).
Beyond these practical uses, 'ضد' appears in discussions about social and political issues. For instance, 'جنبشهای ضد جنگ' (jonbeshhā-ye zed-jang - anti-war movements) or 'مخالفان ضد دولتی' (mokhālefan-e zed-dowlati - anti-government opponents) are terms you might encounter in news or political commentary. The phrase 'ضد انقلاب' (zed-enghelāb - counter-revolutionary) is also frequently used in historical and political contexts.
Even in less formal settings, you might hear about someone being 'ضد حال' (zed-hāal), which is a colloquial way to say someone is a 'buzzkill' or spoils the mood. This demonstrates the prefix's adaptability across different registers.
When watching Iranian films or television shows, pay attention to product advertisements or dialogues discussing health and safety. The term 'ضد عفونی کننده' (zed-ofuni konandeh - disinfectant) is commonly used, especially in medical dramas or during discussions about hygiene. You might also hear about 'ضد یخ' (zed-yakh - antifreeze) in conversations related to cars, particularly in colder regions.
The prefix is also used in describing building materials, such as 'بتن ضد سولفات' (beton zed-sulfāt - sulfate-resistant concrete) for infrastructure projects. This highlights its importance in technical and construction terminology.
In summary, 'ضد' is a highly functional prefix that you will encounter in advertisements, medical advice, news reports, and everyday conversations. Its consistent meaning of 'against' or 'resistant to' makes it a valuable element for understanding a wide range of Persian vocabulary.

While 'ضد' (zed) is a straightforward prefix, learners might make a few common mistakes. Understanding these pitfalls can help you use the word more accurately.
One common error is treating 'ضد' as a standalone word or a separate preposition. Remember, it's a prefix that attaches to another word to form a new concept. For instance, you wouldn't say 'ضد آب است' as 'zed āst' meaning 'against is'. It must be 'ضد آب' (zed-āb) functioning as a single adjective.
Another mistake is misinterpreting its meaning. While 'ضد' often means 'anti-' or 'proof against,' it can also imply 'opposite' or 'contrary to.' For example, 'ضد و نقیض' (zed-o-naghid) means 'contradictory.' Learners might focus too much on the 'proof against' aspect and miss this broader sense of opposition.
Confusion can also arise with words that sound similar or have related meanings. For example, 'ضد' should not be confused with words like 'ضرر' (zarar - harm) or 'ضمانت' (zomānat - guarantee), although they share the initial 'ض' sound. The prefix 'ضد' specifically denotes opposition or resistance.
Learners might also struggle with the grammatical function of the word formed with 'ضد.' Since it usually creates an adjective, it needs to be placed correctly in a sentence. Forgetting this, and using it like a verb or a noun in the wrong position, is a common grammatical error.
For example, if you want to say 'This is an antiviral drug,' a mistake might be to say 'این ضد ویروس دارو است' (In zed-virus dāru ast), placing the adjective before the noun. The correct Persian structure is 'این دارو ضد ویروس است' (In dāru zed-virus ast), where 'ضد ویروس' functions as an adjective modifying 'دارو' (drug).
Another potential issue is overgeneralization. While 'ضد' is versatile, it's not used for every instance of 'against.' For example, to say 'against the law,' you might use 'خلاف قانون' (khalāf-e qānun) rather than a direct 'ضد قانون.' Context is key.
Finally, pronunciation can be a challenge. The 'ض' sound is unique to Arabic-derived words and can be difficult for non-native speakers. Mispronouncing it can lead to misunderstanding, especially since it's a crucial sound in 'ضد'.
- Mistake 1
- Treating 'ضد' as a standalone word instead of a prefix.
- Mistake 2
- Misinterpreting its meaning as only 'proof against,' missing the 'opposition' sense.
- Mistake 3
- Incorrect grammatical placement of the resulting adjective.
غلط: این ضد ویروس است دارو.
صحیح: این دارو ضد ویروس است.
غلط: او یک ضد کتاب نوشت.
صحیح: او یک کتاب ضد جنگ نوشت.
While 'ضد' (zed) is the primary prefix for 'anti-' or 'proof against' in Persian, there are other ways to express similar concepts, depending on the nuance and context. Understanding these alternatives can enrich your vocabulary.
'علیه' (alayh): This Arabic-derived preposition means 'against' or 'in opposition to.' It's often used in more formal or political contexts when expressing direct opposition to something. For example, 'اعتراض علیه' (e'terāz alayh) means 'protest against.' Unlike 'ضد,' 'علیه' is a preposition and typically requires a following noun or pronoun to indicate what is being opposed.
'بر خلاف' (bar khalāf): This phrase means 'contrary to' or 'in contrast to.' It's used to highlight a difference or opposition between two things. For example, 'بر خلاف انتظار' (bar khalāf-e entezār) means 'contrary to expectation.' This is not a direct synonym for 'ضد' but expresses a form of opposition through contrast.
- Word
- ضد (zed)
- Meaning
- Anti-, proof against (prefix)
- Usage
- Forms compound adjectives/nouns, indicates resistance or opposition.
- Example
- ضد آب (zed-āb - waterproof)
- Word
- علیه (alayh)
- Meaning
- Against, in opposition to (preposition)
- Usage
- Expresses direct opposition, often in formal or political contexts.
- Example
- اعتراض علیه طرح (e'terāz alayh-e tarh - protest against the plan)
- Phrase
- بر خلاف (bar khalāf)
- Meaning
- Contrary to, in contrast to
- Usage
- Highlights differences or opposition through comparison.
- Example
- بر خلاف انتظار، او موفق شد (bar khalāf-e entezār, ou movaffaq shod - Contrary to expectation, he succeeded).
'مخالف' (mokhālef): This word means 'opposite,' 'opposed,' or 'opponent.' It can be used as an adjective or a noun. For example, 'مخالف جریان' (mokhālef-e jaryān) means 'against the current.' While 'ضد' is a prefix forming new words, 'مخالف' is a standalone word that expresses opposition.
'نا-' (nā-): This is another prefix, similar to the English 'un-' or 'in-.' It negates the meaning of the word it attaches to, creating an opposite. For example, 'ناپدید' (nāpadid) means 'disappeared' (literally 'unseen'). While 'ضد' implies active resistance or protection, 'نا-' simply indicates the absence of a quality or state. For example, 'نا امن' (nā-amn) means 'insecure,' whereas 'ضد امنیت' (zed-amniat) would imply actively working against security.
Choosing the right word or phrase depends on the specific meaning you want to convey. If you're talking about a product's protective quality, 'ضد' is usually the best choice. For direct opposition in a political or formal sense, 'علیه' might be more appropriate. For highlighting a contrast, 'بر خلاف' is useful. And for general opposition or being against something as a person, 'مخالف' works well.
How Formal Is It?
Fun Fact
The letter 'ض' (zad) in Arabic is one of the 'emphatic' consonants, meaning it's pronounced with a constriction in the pharynx, giving it a deeper, heavier sound than its non-emphatic counterparts. This distinct sound contributes to the unique character of words derived from Arabic.
Pronunciation Guide
- Confusing the 'ض' (zad) sound with 'ز' (zāl) or 'ذ' (zal). The 'ض' sound is a pharyngealized 'd', produced with the back of the tongue raised, making it sound heavier or deeper than a regular 'd'.
- Pronouncing the 'e' sound too long, making it sound like 'zedd' instead of 'zed'.
Difficulty Rating
The prefix itself is straightforward, but understanding the specific words it forms (e.g., 'ضد گلوله' vs. 'ضد درد') requires vocabulary knowledge. Recognizing its function as a prefix is key for comprehension.
Learners should practice forming common compound words with 'ضد' and using them correctly as adjectives or compound nouns in sentences. Understanding word order is important.
Pronouncing the 'ض' sound correctly is crucial. Practice using common phrases like 'ضد آب' and 'ضد آفتاب' in simple sentences.
The prefix 'ضد' is frequently used, so listening for it in context will help learners quickly identify words related to protection or opposition.

Informal/ColloquialEasily Confused
Both imply resistance to something.
'مقاوم' (resistant) is an adjective that often needs a preposition like 'در برابر' (against) to specify what it's resistant to (e.g., مقاوم در برابر آب - water-resistant). 'ضد' is a prefix that combines directly with the noun to form a new word like 'ضد آب' (waterproof), which is often a stronger or more inherent quality.
این پارچه در برابر آب مقاوم است (This fabric is resistant to water). این پارچه ضد آب است (This fabric is waterproof).
Both express opposition.
'ضد' is a prefix that attaches to a word to form a new adjective or noun (e.g., ضد جنگ - anti-war). 'علیه' is a preposition that means 'against' and is used before the object of opposition (e.g., اعتراض علیه جنگ - protest against the war).
آنها موضعی ضد جنگ داشتند (They had an anti-war stance). آنها علیه جنگ اعتراض کردند (They protested against the war).
Both can negate or indicate an absence of something.
'نا-' is a prefix meaning 'un-' or 'in-' (e.g., ناامن - insecure, ناپدید - disappeared). It simply indicates the absence of a quality. 'ضد' implies active resistance, opposition, or protection against something (e.g., ضد امنیت - against security, which implies actively working against it, not just being insecure).
این منطقه ناامن است (This area is insecure). این منطقه ضد امنیت است (This area is hostile to security/actively works against security).
Both are prefixes with 'anti-' or 'counter-' meanings.
'پاد-' is also a prefix, often used in more scientific or formal contexts, like 'پادزهر' (antidote - counter-poison). While 'ضد' can also be used in medical contexts (like 'ضد ویروس'), 'پاد-' specifically implies a counteraction or remedy.
پادزهر برای این سم لازم است (Antidote is needed for this poison). این دارو ضد ویروس است (This medicine is antiviral).
Both can express a form of opposition or difference.
'بر خلاف' means 'contrary to' or 'in contrast to', highlighting a difference or unexpected outcome. 'ضد' implies direct opposition, resistance, or being proof against something.
بر خلاف انتظار، او موفق شد (Contrary to expectation, he succeeded). او یک موضع ضد پیشرفت داشت (He had an anti-progress stance).

How to Use It
Very High
-
Using 'ضد' as a standalone word.
→
It must be used as a prefix attached to another word.
Learners might mistakenly treat 'ضد' like 'against' in English and use it on its own. For example, saying 'من ضد آب هستم' when they mean 'I am waterproof'. The correct form is 'این لباس ضد آب است' (This clothing is waterproof).
-
Mispronouncing the 'ض' sound.
→
Pronounce 'ض' with a deeper, pharyngealized 'd' sound.
The 'ض' sound is distinct from 'ز' or 'ذ'. Incorrect pronunciation can lead to confusion. Practice the sound by feeling the back of your tongue rise and constricting your throat slightly.
-
Confusing 'ضد' with 'مقاوم در برابر'.
→
'ضد' usually implies a stronger, inherent quality ('waterproof'), while 'مقاوم در برابر' means 'resistant to' and might be less absolute.
While similar, 'ضد آب' is typically understood as fully waterproof, whereas 'مقاوم در برابر آب' might suggest resistance up to a certain point. Choose based on the intended level of protection.
-
Incorrect grammatical placement of the adjective.
→
Adjectives formed with 'ضد' follow the noun they modify.
Forgetting Persian adjective order, learners might place the 'ضد' word before the noun, like 'ضد گلوله ماشین'. The correct order is 'ماشین ضد گلوله' (car bulletproof).
-
Overgeneralizing its use for all 'against' concepts.
→
Use context and other words like 'علیه' or 'مخالف' when appropriate.
While 'ضد' works for abstract opposition like 'ضد جنگ', for direct opposition to a person or action, 'علیه' (against) is often more suitable. For example, 'اعتراض علیه' (protest against) rather than 'اعتراض ضد'.
Tips
Mastering the 'ض' Sound
The Persian letter 'ض' (zad) is crucial for words like 'ضد'. It's a pharyngealized 'd', pronounced deeper in the throat than a regular 'd'. Practice by trying to say 'd' while constricting the back of your throat. Listen to native speakers and mimic the sound.
Recognize the Pattern
When you see 'ضد' followed by a noun, think 'resistant to' or 'against'. For example, 'ضد آب' = 'resistant to water' = waterproof. This pattern helps you guess the meaning of new words.
Adjective Placement
Words formed with 'ضد' usually function as adjectives. Remember that in Persian, adjectives typically follow the noun they describe. For instance, 'a waterproof watch' is 'ساعت ضد آب' (sā'at-e zed-āb).
Create Associations
Link 'ضد' to protective imagery. Imagine a shield ('ضد') protecting against rain ('آب'), viruses ('ویروس'), or bullets ('گلوله'). This visual connection can help you recall the meaning and usage.
Active Recall
Don't just read definitions. Try to create your own sentences using common 'ضد' words. For example, write about your 'ضد آب' shoes or a 'ضد درد' medicine you've used. Active use solidifies learning.
Listen for Common Phrases
Pay attention when you hear 'ضد آب', 'ضد آفتاب', 'ضد درد', etc. These are very common. Recognizing them in spoken Persian will significantly boost your comprehension.
Explore Related Concepts
Once you're comfortable with 'ضد', explore related words like 'مقاوم' (resistant), 'علیه' (against - preposition), and 'پاد' (counter- prefix). This broadens your understanding of expressing opposition and protection.
Beyond Physical Protection
Understand that 'ضد' isn't just for physical properties. It's used for abstract ideas too, like 'ضد جنگ' (anti-war). This shows its versatility in expressing stances and ideologies.
Avoid Treating it as a Standalone Word
Remember 'ضد' is a prefix. Don't say 'من ضد آب هستم' (I am against water) intending 'I am waterproof'. It must be 'من ضد آب هستم' (I am waterproof) or 'این لباس ضد آب است' (This clothing is waterproof).
Memorize It
Mnemonic
Imagine a 'ZED' creature (sounds like 'zed') that is fiercely 'against' everything. It wears a 'waterproof' suit ('ضد آب') because it hates getting wet, and carries an 'anti-virus' shield ('ضد ویروس') because it's against all germs. This ZED creature is always ready to fight 'against' anything.
Visual Association
Visualize a large, bold letter 'Z' (representing 'zed') with arrows pointing away from it in all directions, symbolizing opposition and repulsion. Next to it, picture a shield with a 'Z' on it, representing protection and being 'proof against' threats. You can also imagine a 'Z' shape forming a barrier against incoming objects like water droplets or virus icons.
Word Web
Challenge
Try to create five new words using the prefix 'ضد' that you haven't heard before, based on logical combinations (e.g., 'ضد باد' - windproof). Then, use these new words in simple sentences.
Word Origin
The prefix 'ضد' originates from the Arabic word 'ضِدّ' (ḍidd), which means 'opposite', 'contrary', or 'antagonist'. This term has been adopted into Persian and other languages influenced by Arabic.
Original meaning: Opposite, contrary, antagonist.
Semitic (Arabic)Cultural Context
While 'ضد' is generally neutral, its use in political or social contexts (e.g., 'ضد دولتی' - anti-government, 'ضد اجتماعی' - antisocial) can carry strong connotations and should be used with awareness of the specific situation and audience.
In English, similar concepts are expressed using prefixes like 'anti-' (e.g., antiviral, anti-war) or suffixes like '-proof' (e.g., waterproof, bulletproof). The Persian prefix 'ضد' often combines these two meanings.

Frequently Asked Questions
10 questionsYes, 'ضد' functions almost exclusively as a prefix in modern Persian. It attaches to the beginning of another word to form a new word, usually an adjective or a compound noun. You won't typically see it used as a standalone word or a preposition.
'ضد آب' (zed-āb) means 'waterproof', implying a complete inability for water to penetrate. 'مقاوم در برابر آب' (moghāvem dar barābar-e āb) means 'water-resistant', suggesting it can withstand water to a certain degree but might not be completely impervious. 'ضد آب' generally implies a stronger level of protection.
Yes, absolutely. While it's common for physical properties like 'ضد آب' or 'ضد گلوله', 'ضد' is also used with abstract nouns to denote opposition. For example, 'ضد جنگ' (anti-war), 'ضد انقلاب' (counter-revolutionary), or even 'ضد اجتماعی' (antisocial) demonstrate this usage.
Both words start with the Arabic letter 'ض' (zad). The 'ض' sound is a pharyngealized 'd', meaning it's pronounced deeper in the throat than a regular 'd'. While the spelling is the same, the context and the following letters distinguish the words. 'ضد' is pronounced /zɛd/, while 'ضرر' is pronounced /za-rar/.
The primary meanings are 'against' and 'proof against'. However, in idiomatic or colloquial uses like 'ضد حال' (zed-hāal), it means something like 'buzzkill' or 'mood-spoiler', which is an extension of being 'against' fun or good feelings.
Most commonly, words formed with 'ضد' function as adjectives (e.g., 'ضد آب', 'ضد ویروس'). However, some combinations function as compound nouns, such as 'ضد آفتاب' (sunscreen) or 'ضد درد' (painkiller, referring to the medicine itself). The grammatical function depends on the specific word formed.
Yes, 'ضد' is very similar in meaning and function to the English prefix 'anti-' and the suffix '-proof'. Both are used to indicate opposition or resistance.
While 'ضد' fundamentally means 'opposite', it's more commonly used to form specific words indicating resistance or opposition to a particular thing. For general 'opposite directions', you would typically use words like 'مخالف' (opposite) or 'متضاد' (contrasting).
Since words formed with 'ضد' are usually adjectives or compound nouns that describe a property, they don't typically have plural forms in the same way regular nouns do. For example, you don't say 'ضد آبها' (waterproofs); you would refer to multiple items that are waterproof.
The 'ض' sound is unique. Try to feel the back of your tongue rising towards the roof of your mouth while you make a 'd' sound. It's a heavier, deeper sound than a regular 'd'. Listening to native speakers and practicing the sound is the best way to master it.
