At the A1 level, learners are just beginning their journey into the Chinese language. The word 发出 (fā chū) might seem a bit advanced for absolute beginners, but its core concept is quite simple and highly visual. At this stage, the focus should be on the most basic, concrete uses of the word, specifically relating to sounds. Beginners learn that in English, animals 'make' sounds, but in Chinese, they 'emit' sounds using 发出. You will learn to construct very simple sentences like 'The dog emits a sound' (狗发出声音). The vocabulary is kept to familiar, everyday nouns like animals, cars, and people. You will also learn the basic SVO (Subject-Verb-Object) structure, which is foundational for Chinese grammar. The goal at A1 is not to master all the abstract uses of the word, but simply to recognize it when hearing about noises and to be able to describe simple auditory events in your immediate environment. You will practice pairing 发出 with the word 声音 (shēng yīn), meaning sound or voice, as this is the most frequent and useful collocation for a beginner. By mastering this single phrase—发出声音—you unlock the ability to describe a vast array of actions, from a baby crying to a telephone ringing, setting a strong foundation for more complex descriptions later on.

As learners progress to the A2 level, their vocabulary expands, and so does their ability to use 发出 (fā chū). At this stage, you move beyond just sounds and begin to incorporate light (光 - guāng) and simple signals (信号 - xìn hào). You will learn to describe everyday objects like flashlights, lamps, and computer screens emitting light. The sentence structures become slightly more complex. Instead of just saying 'it makes a sound,' you will start adding simple adjectives using the '的' (de) particle to describe the quality of the emission. For example, you will learn to say 'The machine emits a loud sound' (机器发出很大的声音) or 'The phone emits a red light' (手机发出红光). This level also introduces the concept of using 发出 for simple human actions, such as letting out a laugh (发出笑声) or a sigh. The focus remains on tangible, observable phenomena, but the descriptive power of your sentences increases significantly. You will also begin to encounter the word in simple reading texts, such as short stories or basic instructions, where understanding that an object is sending something outward is crucial for comprehension. The A2 level bridges the gap between basic identification and descriptive communication.

At the B1 level, learners are ready to tackle the abstract and more nuanced applications of 发出 (fā chū). This is a critical transition point where the word moves from describing purely physical phenomena (sound, light) to describing social and administrative actions. You will learn to use 发出 with abstract nouns such as warnings (警告 - jǐng gào), invitations (邀请 - yāo qǐng), and notices (通知 - tōng zhī). The grammar also becomes more sophisticated. You will frequently use prepositional phrases, particularly with 向 (xiàng - towards), to indicate the recipient of the emission. For example, 'The school issued a notice to the students' (学校向学生发出通知). This structure is essential for discussing communication between entities. Furthermore, you will begin to differentiate 发出 from its synonyms, learning why you cannot use it for mailing physical letters (which requires 寄出). The B1 level requires you to understand the context in which a word is used, not just its literal translation. You will encounter 发出 in news headlines, formal emails, and more complex narratives, requiring a solid grasp of both its physical and abstract meanings to fully comprehend the text and express yourself accurately in intermediate-level conversations.

Reaching the B2 level means you are achieving a high degree of fluency and can handle complex, professional, and academic contexts. At this stage, your use of 发出 (fā chū) becomes highly refined. You will use it effortlessly in discussions about technology, science, and official procedures. Vocabulary pairings become more advanced, including terms like directives (指令 - zhǐ lìng), appeals (呼吁 - hū yù), and radiation (辐射 - fú shè). You will be comfortable reading news articles where governments or international bodies 发出 statements or sanctions. In terms of grammar, you will master the use of the 把 (bǎ) structure with 发出, allowing you to emphasize the manipulation and dispatch of information or signals. For example, 'He sent the distress signal out' (他把求救信号发出了). You will also understand the subtle stylistic differences between 发出 and formal synonyms like 发布 (fā bù), knowing exactly when to use which based on the register of the conversation or text. At B2, 发出 is no longer just a vocabulary word to memorize; it is a versatile tool that you use naturally to construct sophisticated arguments, describe complex systems, and navigate formal Chinese environments with confidence.

At the C1 level, your command of Chinese is approaching that of a native speaker. Your use of 发出 (fā chū) is characterized by precision, idiomatic usage, and a deep understanding of literary and rhetorical contexts. You will encounter and use the word in highly descriptive, evocative literature. Instead of simply saying someone laughed, you might read or write about someone 'emitting a hollow, echoing laugh that chilled the room' (发出空洞而令人不寒而栗的笑声). The word is used to create atmosphere and convey subtle emotional undertones. You will also use it in complex metaphorical senses, such as an economic indicator 'emitting a warning signal' about an impending recession. At this level, you are fully aware of the collocations and fixed expressions that utilize 发出, and you can manipulate them for stylistic effect. You understand the historical and cultural weight of official decrees being 'issued' and can discuss these topics using appropriate, high-level vocabulary. The distinction between 发出 and its myriad synonyms is second nature to you, allowing you to choose the exact right word to convey the precise shade of meaning required by the context, whether you are writing an academic paper, giving a formal presentation, or engaging in a deep philosophical debate.

At the C2 level, the mastery of 发出 (fā chū) is absolute. You understand the word not just functionally, but etymologically and culturally. You can effortlessly navigate classical references or highly specialized jargon where the concept of emission or issuance is central. In technical fields like quantum physics or advanced telecommunications, you use 发出 to describe complex phenomena with native-like accuracy. In literature, you appreciate how authors use the word to break silence or darkness, understanding the dramatic tension inherent in the characters 发 (to shoot forth) and 出 (to emerge). You can play with the word, using it in creative, non-standard ways that still make perfect sense within the rules of Chinese rhetoric. You can instantly detect when a non-native speaker uses the word slightly unnaturally, even if it is grammatically correct, because your intuition for the word's collocations and register is fully developed. At this pinnacle of language proficiency, 发出 is seamlessly integrated into your vast mental lexicon, serving as a foundational concept that supports your ability to articulate the most complex, abstract, and nuanced thoughts imaginable in the Chinese language.

To let out an emotion (sigh/laugh).

The Chinese verb 发出 (fā chū) is a highly versatile and essential word in the language, functioning primarily to describe the action of emitting, sending out, or issuing something from a source to the outside world. To truly understand this word, we must break down its two constituent characters. The first character, 发 (fā), carries the core meaning of to send, to issue, to shoot, or to start. It is a dynamic character that implies movement outward from a point of origin. The second character, 出 (chū), acts as a directional complement meaning out or to emerge. When combined, 发出 literally translates to send out or to issue forth. This compound creates a vivid image of something originating internally and crossing a boundary into the external environment.

In everyday communication, people use 发出 in a wide variety of contexts, ranging from the physical to the abstract. Physically, it is most commonly associated with sensory phenomena. For instance, when a machine starts up, it might 发出 (emit) a loud noise. When a firefly glows in the dark, it is described as 发出 (emitting) light. Even the human body utilizes this verb; when someone sighs deeply, they 发出 a sigh, and when a baby giggles, they 发出 a joyful sound. The word captures the exact moment that a sound, light, or smell leaves its source and becomes perceivable to others.

Physical Emission: Used for sounds, lights, and smells. For example, a speaker emitting music or a flashlight emitting a beam of light.
Abstract Issuance: Used for sending out non-physical items like warnings, invitations, commands, or signals to a group of people or a specific recipient.
Emotional Expression: Used when emotions manifest as physical sounds, such as letting out a cry of despair or a shout of triumph.

Beyond physical emissions, 发出 is heavily utilized in administrative, social, and technological contexts. When a government agency needs to alert the public about an incoming storm, they will 发出 a warning. When a couple decides to get married, they will 发出 invitations to their friends and family. In the realm of technology, a satellite will 发出 signals back to Earth, and a computer program might 发出 an error code when something goes wrong. In these abstract usages, the word maintains its core concept: an entity (the sender) is generating a message or directive and pushing it outward into the world for others to receive and interpret.

The old engine sputtered and 发出 a terrible grinding noise before finally dying.

The committee decided to 发出 a formal apology to the affected community members.

As the sun set, the lighthouse began to 发出 its sweeping beam of light across the dark ocean.

The trapped animal 发出 a pitiful whimper that broke everyone's heart.

The general stood before his troops to 发出 the final command for the morning offensive.

It is important for learners to recognize that while 发出 translates to send out, it is rarely used for sending physical objects like parcels or letters through the mail. For mailing physical items, Chinese uses words like 寄出 (jì chū) or 发送 (fā sòng). 发出 is reserved almost exclusively for intangibles: sounds, light, smells, signals, warnings, orders, and invitations. This distinction is crucial for achieving natural fluency. When you think of 发出, visualize waves—sound waves, light waves, radio waves, or metaphorical waves of information—radiating outward from a central point. This mental image will help you apply the word correctly in almost any situation.

Mastering the grammatical structure of 发出 (fā chū) is essential for constructing natural-sounding Chinese sentences. As a transitive verb, 发出 almost always requires a direct object. The standard sentence pattern follows the classic Subject + Verb + Object (SVO) structure: [Subject/Source] + 发出 + [Object/Emission]. The subject is the entity responsible for the emission—this can be a person, an animal, a machine, an organization, or even a natural phenomenon. The object is the thing being emitted, which, as established, is typically an intangible noun such as sound (声音), light (光芒), a signal (信号), a warning (警告), or an invitation (邀请). Understanding this core structure allows learners to generate a vast array of descriptive and functional sentences.

Basic SVO Structure: Subject + 发出 + Object. Example: 机器发出声音 (The machine emits a sound).
With Aspect Particle 了 (le): Subject + 发出了 + Object. Used to indicate that the action of emitting has been completed. Example: 他发出了警告 (He issued a warning).
With Descriptive Modifiers: Subject + 发出 + [Adjective + 的] + Object. Example: 狗发出可怕的叫声 (The dog let out a terrifying bark).

One of the most common ways to enhance sentences using 发出 is by adding descriptive modifiers to the object. Because 发出 deals with sensory output, adjectives play a crucial role in painting a vivid picture. Instead of simply saying a bird emitted a sound (鸟发出声音), you can say the bird emitted a crisp, melodic chirp (鸟发出清脆的叫声). The modifier is placed between 发出 and the object, usually connected by the structural particle 的 (de). This pattern—发出 + Adjective + 的 + Noun—is ubiquitous in Chinese literature, journalism, and daily conversation. It allows speakers to convey not just the occurrence of an emission, but its exact quality, intensity, and emotional resonance.

The broken radio suddenly 发出 a sharp, piercing static noise.

The university has officially 发出 acceptance letters to the new batch of students.

Deep in the forest, the mysterious glowing plants 发出 a soft, blue luminescence.

Before the earthquake struck, the local seismology bureau 发出 an emergency evacuation alert.

When she saw the surprise gift, she couldn't help but 发出 a gasp of sheer delight.

Furthermore, 发出 is frequently used in conjunction with prepositional phrases to indicate the target or recipient of the emission. The preposition 向 (xiàng), meaning towards or to, is commonly employed. The structure becomes: Subject + 向 + Target + 发出 + Object. For example, 他向我发出邀请 (He issued an invitation to me) or 警方向公众发出警告 (The police issued a warning to the public). This structure is particularly important when dealing with abstract emissions like signals, commands, and invitations, where the destination of the message is just as important as the message itself. By mastering these grammatical patterns, learners can elevate their Chinese from simple, fragmented statements to complex, fluid, and highly descriptive expressions.

The beauty of the word 发出 (fā chū) lies in its omnipresence across various domains of Chinese life. It is not a word confined to textbooks or formal literature; it is a highly active, high-frequency verb that you will encounter daily in both spoken and written contexts. One of the most common places you will hear this word is in the context of news and media. News anchors frequently use 发出 when reporting on official actions. You will hear phrases like 政府发出声明 (the government issued a statement), 气象局发出台风预警 (the meteorological bureau issued a typhoon warning), or 联合国发出呼吁 (the United Nations issued an appeal). In these journalistic settings, 发出 lends a tone of authority and officialdom to the action being described.

In the realm of science, technology, and medicine, 发出 is indispensable. When reading a manual for an electronic device, you might see instructions explaining what it means when the device 发出 a continuous beep versus a flashing light. In scientific documentaries, narrators describe stars that 发出 intense radiation or deep-sea creatures that 发出 bioluminescent glows. In medical contexts, a doctor might ask a patient to 发出 a specific sound (like saying 'ah') to examine their throat. The word perfectly encapsulates the objective, observable phenomenon of energy, data, or sound radiating from a specific source, making it a staple vocabulary word in technical and academic discourse.

News and Journalism: Frequently used to report on official statements, warnings, appeals, and public notices issued by authorities or organizations.
Science and Technology: Used to describe devices emitting signals, machines making operational noises, or natural phenomena emitting light and radiation.
Everyday Social Interactions: Commonly heard when discussing sending out wedding invitations, issuing challenges in games, or describing someone's sudden laughter or sigh.

However, 发出 is equally at home in casual, everyday conversations and creative writing. When friends are gossiping, one might describe how someone 发出了一声冷笑 (let out a cold laugh) to convey disdain. In a suspenseful novel, the author will build tension by describing how the floorboards 发出了吱吱的声音 (emitted a creaking sound) in the dead of night. If you are organizing a party, you will tell your friends that you have already 发出了邀请 (sent out the invitations). It is this seamless transition between the highly formal and the deeply personal that makes 发出 such a critical word for learners to master. It bridges the gap between understanding a formal news broadcast and chatting with a friend about a strange noise your car is making.

The news anchor announced that the health department had 发出 a strict quarantine order.

My smartphone 发出 a low battery alert right in the middle of the important conference call.

The bride and groom excitedly 发出 their beautifully designed wedding invitations to over two hundred guests.

In the horror movie, the haunted doll suddenly 发出 a sinister, echoing giggle.

When immersing yourself in Chinese media, pay close attention to the verbs used with sensory nouns. You will quickly notice that English uses a variety of verbs—make a sound, give off light, let out a sigh, issue a warning—whereas Chinese elegantly consolidates these actions under the single, powerful umbrella of 发出. This consolidation simplifies the learning process in one sense, but requires a shift in mindset. You must train your brain to associate the concept of outward emission, regardless of the specific medium (sound, light, data, emotion), with the characters 发出. By actively listening for this word in Chinese dramas, podcasts, and news clips, you will rapidly internalize its broad spectrum of applications.

Because English uses several different verbs to cover the meanings encapsulated by 发出 (fā chū), English-speaking learners frequently make errors when trying to translate their thoughts directly into Chinese. One of the most prevalent mistakes is confusing 发出 with other verbs that share the character 发 (fā). For example, learners often confuse 发出 (to emit/issue) with 发生 (fā shēng, to happen/occur). A student might incorrectly say 机器发生声音 (the machine happens a sound) instead of the correct 机器发出声音 (the machine emits a sound). While both words deal with something originating or starting, 发生 is strictly used for events and occurrences (like accidents or changes), whereas 发出 requires a tangible or intangible object being sent outward.

Another common stumbling block is the confusion between 发出 and 发现 (fā xiàn, to discover/find). This usually happens due to phonetic similarity and the shared first character. A learner might say 我发现了一个警告 (I discovered a warning) when they actually mean to say they issued a warning (我发出了一个警告). This completely changes the meaning of the sentence from being the creator of the warning to being the recipient or observer of it. It is crucial to drill the meanings of these compound words: 发 (issue) + 出 (out) = emit; 发 (issue/open) + 现 (appear) = discover. Understanding the logic of the second character (the complement) is the key to avoiding these mix-ups.

发出 vs. 发生 (fā shēng): 发出 means to emit or issue an object (sound, light, warning). 发生 means to happen or occur (an event, an accident). Do not use 发生 for making sounds.
发出 vs. 寄出 (jì chū): 发出 is for intangible things (signals, sounds, digital invitations). 寄出 is specifically for mailing physical objects through a postal service (letters, packages).
发出 vs. 发送 (fā sòng): 发送 is primarily used for sending digital messages, emails, or data files. While there is overlap, 发出 is broader and covers physical emissions (light/sound) which 发送 cannot do.

A third major area of confusion involves the physical act of sending items. In English, we send a letter, send an email, and send a signal. In Chinese, these require different verbs. Using 发出 to describe mailing a physical package (e.g., 我发出一个包裹) sounds unnatural to native speakers. The correct verb for mailing physical items is 寄出 (jì chū). Similarly, while you can say 发出电子邮件 (issue an email), it is much more natural and common to use 发送 (fā sòng) for digital communications like texts and emails. Reserving 发出 for sensory emissions (sound, light, smell) and authoritative or broad issuances (warnings, commands, general invitations) will make your Chinese sound much more authentic and precise.

Incorrect: 昨天我的车发生了奇怪的声音。 (My car happened a strange sound yesterday.)

Correct: 昨天我的车发出了奇怪的声音。 (My car emitted a strange sound yesterday.)

Incorrect: 我已经把包裹发出了。 (I have already emitted the package.)

Correct: 我已经把包裹寄出了。 (I have already mailed the package.)

Correct usage of 发出: 老师向同学们发出了参加比赛的邀请。 (The teacher issued an invitation to the students to participate in the competition.)

Finally, learners sometimes struggle with the placement of the object when using the 把 (bǎ) structure. Because 发出 involves moving something outward, it is a perfect candidate for the 把 structure, which emphasizes the disposal or manipulation of an object. The correct pattern is Subject + 把 + Object + 发出 + Directional Complement (if needed). For example, 他把信号发出了 (He sent the signal out). A common mistake is forgetting the object entirely or placing it after 发出 when using 把, which breaks the grammatical rules of the structure. Consistent practice with the SVO and 把 structures specifically using intangible nouns will eliminate these common errors.

The Chinese lexicon is rich with verbs that describe the act of sending, emitting, or distributing. While 发出 (fā chū) is an excellent general-purpose word, knowing its synonyms and alternatives allows for much greater precision and stylistic variety in your communication. By comparing 发出 with similar vocabulary, we can better define its exact boundaries and nuances. One closely related word is 散发 (sàn fā). While both can mean to emit, 散发 specifically emphasizes the dispersion or spreading out of something into the surrounding environment. It is most commonly used for smells, heat, or abstract qualities like charm. A flower 散发 (radiates/emits) a sweet fragrance, whereas a machine 发出 (emits) a sharp noise. 散发 implies a gentle, continuous spreading, while 发出 can be a sudden, discrete event.

Another important alternative is 放射 (fàng shè). This word is much more technical and scientific than 发出. It translates directly to radiate or emit radiation. You would use 放射 when discussing radioactive materials, X-rays, or intense beams of energy. While you could technically say the sun 发出光芒 (emits light), saying the sun 放射光芒 (radiates light) sounds more powerful and scientifically descriptive. In everyday conversation, 放射 is rarely used, making 发出 the preferred choice for general light emission (like a flashlight or a firefly).

散发 (sàn fā) - To diffuse / radiate: Best used for smells, heat, and abstract auras. Emphasizes spreading out in all directions. Example: 玫瑰散发出香味 (The rose diffuses a fragrance).
放射 (fàng shè) - To radiate (scientific): Used in scientific contexts for radiation, intense light, or energy beams. Example: 放射性物质 (Radioactive material).
发布 (fā bù) - To publish / release: Used exclusively for official information, news, software updates, or government decrees. Example: 发布新闻 (To release news).

When dealing with the issuance of information, 发布 (fā bù) is a critical synonym to understand. 发布 translates to publish, release, or promulgate. It is highly formal and is used when an authority makes information public. A tech company will 发布 (release) a new smartphone model or software update. The government will 发布 (publish) new regulations. While an organization might 发出 (issue) a warning, they 发布 (release) a comprehensive report. 发出 focuses on the act of sending the message out from the source, whereas 发布 focuses on making the information broadly available to the public domain.

The bakery 散发 (diffuses) the irresistible smell of fresh bread every morning.

The hospital's X-ray machine 放射 (radiates) energy that can penetrate human tissue.

The software company officially 发布 (released) the latest version of their operating system today.

I need to 发送 (send) an important email to my boss before the end of the day.

The post office requires you to pack the box securely before you 寄出 (mail) it.

Finally, as mentioned in the common mistakes section, 发送 (fā sòng) and 寄出 (jì chū) are alternatives used for sending digital and physical items, respectively. To summarize the landscape of these verbs: use 发出 for sounds, lights, and general issuances; use 散发 for smells and auras; use 放射 for scientific radiation; use 发布 for official public releases; use 发送 for digital messages; and use 寄出 for physical mail. By categorizing these verbs based on the nature of the object being sent, learners can navigate the complexities of Chinese vocabulary with confidence and precision, ensuring their speech is not only grammatically correct but also contextually appropriate.

आम गलतियाँ

Pronouncing 'chū' like the English 'shoe' instead of 'chew'. It needs a hard 'ch' sound.
Failing to keep the tones high and flat. Beginners often drop the pitch on the second syllable.
Confusing the pinyin 'c' (ts sound) with 'ch' (retroflex ch sound). It is NOT 'fā cū'.
Making the 'a' in 'fā' sound like the 'a' in 'cat'. It should be an open 'ah' sound.
Shortening the vowels. First tones should be held slightly longer than other tones.

发出 vs 发生

Both share the character 发 and relate to something starting. English speakers often say 'a sound happened' in their heads.

发生 requires an event as its subject or object (e.g., an accident happened). 发出 requires a source emitting an intangible object (e.g., a machine emitted a sound).

事故发生了 (An accident happened). 机器发出了声音 (The machine emitted a sound).

发出 vs 发现

Phonetic similarity and shared first character. Both are common verbs.

发现 is about perception (finding something that already exists). 发出 is about creation/emission (sending something out into the world).

我发现了秘密 (I discovered a secret). 我发出了警告 (I issued a warning).

发出 vs 寄出

Both translate to 'send out' in English.

寄出 is strictly for mailing physical objects via a postal or courier service. 发出 is for intangible things like signals, sounds, or abstract invitations.

我寄出了包裹 (I mailed the package). 我发出了邀请 (I sent out the invitation).

发出 vs 发送

Both translate to 'send'.

发送 is used for digital communication (emails, texts, files). 发出 is broader, covering physical phenomena (light/sound) and formal issuances.

发送电子邮件 (Send an email). 发出耀眼的光芒 (Emit a dazzling light).

发出 vs 发布

Both are used for official information and share the character 发.

发布 means to publish or release to the general public (news, software, laws). 发出 means to issue or send out, often to a specific target or as a general emission.

发布新闻 (Publish news). 发出通知 (Issue a notice).

सुझाव

The Object is Mandatory

发出 is a transitive verb. It almost always requires an object. You cannot just say '机器发出' (The machine emits). You must specify what it emits: '机器发出声音' (The machine emits a sound).

Don't Translate 'Make'

When English says 'make a noise', 'make a sound', or 'make a beep', do not use the Chinese verb 做 (zuò). Always substitute 'make' with 发出 when dealing with sounds.

Official Language

Listen for 发出 in news broadcasts. It is the standard verb for governments or organizations 'issuing' statements, warnings, or guidelines.

Keep Tones High

Both 发 (fā) and 出 (chū) are first tones. Keep your voice high and flat for both syllables. Don't let your pitch drop at the end of the word.

Pair with 声音

The most common and useful pairing for beginners is 发出声音. Memorize this as a single chunk of vocabulary to instantly improve your fluency.

Placement of 了

When indicating past/completed action, the particle 了 goes after the entire verb compound. It is 发出了, not 发了出.

Intangible Objects Only

Remember the golden rule: if you can physically hold it in your hand (like a letter or an apple), do not use 发出 to send it. Use it for intangibles.

发送 for Digital

If you are talking about sending an email, a text message, or a file on WeChat, use 发送 (fā sòng), not 发出.

Using 向 for Targets

If you want to say WHO you are sending the warning or invitation to, use the structure: Subject + 向 + Target + 发出 + Object.

Look for the Source

When reading, the subject of 发出 is always the source of the emission. Identifying the subject helps you understand where the sound, light, or signal is coming from.

याद करें

स्मृति सहायक

Imagine a FATHER (fā) CHEWING (chū) loudly. He is EMITTING a terrible sound. Fa-chu = Emit sound.

दृश्य संबंध

Visualize a cartoon megaphone. The megaphone is the source (发). The sound waves coming OUT of the megaphone represent (出). Together, the megaphone is 发出 (emitting) sound.

चैलेंज

Look around your room right now. Identify three things that can 发出声音 (emit sound) and three things that can 发出光 (emit light). Say the sentences out loud in Chinese. For example: 我的电脑发出光。

शब्द की उत्पत्ति

The word 发出 is a compound of two ancient Chinese characters. 发 (fā) originally depicted a bow shooting an arrow, symbolizing the act of sending forth or launching. Over time, its meaning expanded to include issuing, starting, and emitting. 出 (chū) is an ideogram that originally depicted a foot stepping out of a cave or a plant sprouting from the ground, representing the concept of going out or emerging.

मूल अर्थ: The original literal meaning when combined was 'to shoot out' or 'to send out'.

Sino-Tibetan

सांस्कृतिक संदर्भ

notes: When using 发出 with bodily sounds (like burping or passing gas), it is considered impolite in formal company, just as in Western cultures. Use more discreet language if necessary.

English speakers often use 'make' for sounds (make a noise) and 'give' for light (give off light). In Chinese, these are unified under 发出.

The phrase '发出时代的最强音' (Emit the strongest voice of the era) is a common rhetorical device in Chinese political and historical speeches. In the famous sci-fi novel 'The Three-Body Problem' (三体), humanity debates whether to 发出 (send out) a signal to the universe, a central plot point. The classic poem line '向天公发出挑战' (Issue a challenge to the heavens) represents human resilience.

अक्सर पूछे जाने वाले सवाल

10 सवाल

No, you should not use 发出 for sending physical mail. The correct word for mailing a letter or package is 寄出 (jì chū). 发出 is reserved for intangible things like sounds, light, signals, or abstract concepts like warnings and invitations.

In Chinese, you do not 'make' (做 - zuò) a sound. You 'emit' a sound. The correct phrase is 发出声音 (fā chū shēng yīn). For example, 'The dog makes a sound' is 狗发出声音.

发生 (fā shēng) means 'to happen' or 'to occur', and is used for events, accidents, or changes. 发出 (fā chū) means 'to emit' or 'to issue', and is used when a source sends out a sound, light, or signal. Never say a sound 'happens' (发生声音); always say it is 'emitted' (发出声音).

发出 is a neutral word that can be used in both highly formal and very informal contexts. It is just as appropriate for a government issuing a decree (formal) as it is for a baby letting out a giggle (informal). The formality depends on the noun it is paired with.

Yes, absolutely. Because 发出 involves manipulating an object and sending it outward, it works perfectly with the 把 structure. For example, '他把信号发出了' (He sent the signal out).

The preposition 向 (xiàng) means 'towards' or 'to'. When you issue a warning, invitation, or signal, it usually has a recipient. You use 向 to indicate who is receiving the emission. Example: 向公众发出警告 (Issue a warning to the public).

Yes. A person can 发出 a sound (like a sigh or a laugh), and a person can also 发出 an abstract item like an invitation, a warning, or an order. Example: 他发出了叹息 (He let out a sigh).

发出光芒 (fā chū guāng máng) means 'to emit light' or 'to radiate'. It is a very common collocation used for the sun, stars, lamps, or anything that glows.

Yes, you can say 发出气味 (emit a smell), although the word 散发 (sàn fā) is often preferred for smells because it emphasizes the diffusion or spreading out of the scent.

You use 了 (le) after 出 (making it 发出了) if you want to indicate that the action of emitting has been completed. If you are stating a general fact (e.g., The sun emits light), you do not use 了.
