有空

The Chinese phrase 有空 (yǒu kòng) is a fundamental expression used to indicate that someone has free time, is available, or is not currently occupied with tasks or responsibilities. It is composed of two distinct characters that, when combined, create a highly versatile and frequently used term in everyday Mandarin. The first character, 有 (yǒu), is a verb meaning 'to have' or 'to possess.' It is one of the most common verbs in the Chinese language, used to indicate existence or possession. The second character, 空 (kòng), in this specific fourth-tone pronunciation, means 'empty space,' 'leisure,' or 'free time.' It is crucial to note the pronunciation here, as the character 空 can also be pronounced in the first tone (kōng), which means 'sky' or 'empty' in a physical sense, such as in 空气 (kōngqì - air) or 空间 (kōngjiān - space). When pronounced as kòng, it specifically refers to a gap in one's schedule or an unoccupied moment. Therefore, the literal translation of 有空 is 'to have empty space (in one's schedule),' which perfectly translates to the English concept of 'having free time' or 'being available.'

Literal Meaning

To possess (有) empty space or a gap (空) in one's schedule, directly equating to having leisure time or availability for activities outside of one's primary obligations.

Understanding the nuance of this phrase is essential for beginners because it forms the basis of social interaction, scheduling, and making plans. In Chinese culture, directly asking someone if they are free before proposing an activity is considered polite and respectful of their time. The phrase is not limited to formal scheduling; it is equally prevalent in casual contexts. For instance, when friends want to hang out, they will almost always start the conversation by asking if the other person has free time. This reflects a cultural emphasis on consideration and avoiding imposition. Furthermore, the concept of 'free time' in modern Chinese society has evolved. With fast-paced work environments, especially in major cities, having '空' (kòng) is highly valued. Therefore, when someone says they have free time, it is often seen as an opportunity for social bonding, relaxation, or pursuing personal interests. The phrase can be used as a standalone statement, such as '我有空' (I am free), or as part of a question, like '你今天有空吗？' (Are you free today?).

Social Function

Serves as the primary conversational gateway for extending invitations, arranging meetings, and demonstrating politeness by checking someone's availability before making a request.

Beyond simple availability, the phrase can also carry a sense of willingness. When someone says '等我有空' (wait until I have free time), it can sometimes be a polite deferral, similar to the English 'when I get around to it.' However, in most direct interactions, it is a straightforward declaration of availability. It is also worth noting that the phrase is highly modular. You can attach various time words to it to specify exactly when you are free. For example, '周末有空' (free on the weekend), '随时有空' (free anytime), or '现在有空' (free right now). This modularity makes it an incredibly powerful tool for learners at the A1 level, as it allows them to construct a wide variety of useful sentences with minimal vocabulary. The negation of this phrase is equally important: '没空' (méi kòng), meaning 'not free' or 'busy.' Notice that we use 没 (méi) to negate 有 (yǒu), never 不 (bù). This is a fundamental grammar rule in Chinese that applies universally to the verb 有.

Grammatical Note

The verb 有 (to have) is exclusively negated by 没 (méi), resulting in 没空 (méi kòng) for 'not free'. Using 不空 (bù kòng) is grammatically incorrect and sounds unnatural to native speakers.

Using 有空 correctly involves understanding its placement within a Chinese sentence structure, which generally follows the Subject-Time-Verb-Object (STVO) or Time-Subject-Verb-Object (TSVO) pattern. Because '有空' functions as a verb phrase meaning 'to have free time,' it occupies the verb position in the sentence. The most common way to use it is by placing a time word directly before it. For example, '我明天有空' (I tomorrow have free time). The time word '明天' (tomorrow) can also be placed at the beginning of the sentence for emphasis: '明天我有空' (Tomorrow, I have free time). Both structures are perfectly natural and widely used. When forming questions, you can use the standard yes/no question particle '吗' (ma) at the end of the sentence: '你明天有空吗？' (Are you free tomorrow?). Alternatively, you can use the affirmative-negative question structure, which is very common in spoken Chinese: '你明天有没有空？' (Do you have free time tomorrow or not?). This structure is formed by combining the verb (有), its negation (没有), and the object (空).

Sentence Structure

Subject + Time Word + 有空 + (Verb Phrase). For example: 我(Subject) + 周末(Time) + 有空(Verb Phrase) + 去看电影(Action).

Another highly frequent usage pattern involves linking '有空' with a subsequent action. When you want to say 'When you have free time, do [action],' you can use the structure '有空 + (的)时候 + Verb' or simply '有空 + Verb'. For example, '有空的时候，我喜欢看书' (When I have free time, I like to read books). In casual speech, the '的时候' (de shíhou - when) is often dropped, resulting in the more concise '有空常联系' (Keep in touch when you have free time) or '有空来我家玩' (Come to my house to play when you have free time). This structure is incredibly useful for making polite suggestions or open-ended invitations. It removes the pressure of an immediate commitment while still expressing a desire to interact. Furthermore, you can use degree adverbs to modify the amount of free time, though this is slightly less common than modifying the busyness. For instance, you can say '我很有空' (I have a lot of free time / I am very free), but it is more typical to hear the negative counterpart '我很忙' (I am very busy) or '我完全没空' (I have absolutely no free time).

Action Linkage

Use '有空 + Verb' to suggest an action to be done during free time, acting as a polite, low-pressure invitation or suggestion.

It is also important to understand how to respond to questions involving '有空'. If someone asks '你今天有空吗？', a positive response can be as simple as '有' (have), '有空' (have free time), or '有的' (yes, I have). A negative response would be '没有' (don't have) or '没空' (don't have free time). To be more polite when declining, it is customary to add a reason or an apology, such as '不好意思，我今天没空，我很忙' (Sorry, I don't have free time today, I am very busy). You can also use conditional structures with '有空'. For example, '如果我有空，我就去' (If I have free time, I will go). The word '如果' (rúguǒ - if) sets up the condition, and '就' (jiù - then) introduces the result. This conditional usage is a step towards more complex sentence building, allowing learners to express hypothetical situations regarding their availability. Mastering these various structures—basic statements, questions, linked actions, and conditionals—will provide a solid foundation for navigating daily social interactions in Mandarin.

Polite Declinations

When responding negatively (没空), it is culturally expected to soften the refusal with an apology (不好意思) and a brief explanation of why you are busy.

The phrase 有空 is ubiquitous in Chinese-speaking environments, permeating almost every aspect of daily life where human interaction and scheduling occur. You will hear it constantly in casual social settings, such as among friends, family members, and classmates. When planning a get-together, a dinner, a movie outing, or simply a phone call, checking someone's availability is the mandatory first step. In these informal contexts, the tone is usually light and relaxed. For example, a friend might text you on a Friday afternoon asking, '周末有空吗？出去玩啊！' (Are you free this weekend? Let's go out and play!). It is also heavily used in dating scenarios. Asking a romantic interest '你这周哪天有空？' (Which day are you free this week?) is the standard, polite way to initiate a date without being overly aggressive. The phrase acts as a social lubricant, ensuring that invitations are extended only when the other party is likely to be receptive, thereby saving face for both individuals if the timing is inconvenient.

Social Settings

The most frequent environment for this phrase is casual socializing, where it functions as the polite prerequisite for any invitation or proposal to spend time together.

Beyond casual socializing, '有空' is also highly prevalent in the workplace, though the context and tone may shift slightly. In a professional environment, respecting colleagues' time is paramount. Before interrupting a coworker or scheduling a meeting, it is customary to ask, '你现在有空吗？' (Are you free right now?) or '老板，您下午有空签个字吗？' (Boss, do you have free time this afternoon to sign a document?). In these situations, the phrase demonstrates professional courtesy. It acknowledges that the other person may be engaged in important tasks and gives them the opportunity to defer the interaction if necessary. Customer service representatives also frequently use this phrase. For instance, a telemarketer or a bank representative might start a call with '请问您现在有空接听电话吗？' (Excuse me, do you have free time to take a call right now?). This polite inquiry sets a respectful tone for the conversation. Furthermore, in business networking, ending a conversation with '下次有空一起喝茶' (Let's have tea together next time you have free time) is a standard, polite way to express a desire for future collaboration without making an immediate, hard commitment.

Professional Contexts

Used to demonstrate professional courtesy and respect for colleagues' schedules before interrupting them or requesting a meeting or action.

You will also encounter '有空' in media, literature, and everyday public interactions. In television dramas and movies, characters frequently use this phrase to drive the plot forward through meetings and dates. It is a staple of realistic dialogue. In public spaces, such as retail stores or salons, staff might ask if you have time to browse or wait. For example, a hairdresser might say, '现在人多，您有空等二十分钟吗？' (There are many people now, do you have free time to wait for twenty minutes?). Additionally, the phrase appears in common idiomatic expressions and polite formulas. The phrase '有空常来' (Come often when you have free time) is a classic parting phrase used by hosts to guests or shop owners to customers, signifying hospitality and a welcoming attitude. Understanding the diverse environments where '有空' is used helps learners appreciate its versatility. It is not just a vocabulary word; it is a cultural key that unlocks polite and effective communication across a wide spectrum of Chinese society, from the most intimate friendships to formal business relationships.

Public & Retail

Encountered when staff inquire about a customer's willingness to wait or participate in an activity, managing expectations and demonstrating polite service.

While 有空 is a relatively straightforward phrase, learners frequently stumble over a few specific grammatical and phonetic hurdles. The most prominent mistake involves the negation of the verb 有 (yǒu). In Chinese, almost all verbs can be negated with 不 (bù), but 有 is the absolute exception. It must always be negated with 没 (méi) or 没有 (méiyǒu). Therefore, to say 'I don't have free time,' you must say '我没空' (wǒ méi kòng). A very common beginner error is saying '我不空' (wǒ bù kòng). This sounds entirely unnatural to a native speaker and immediately marks the speaker as a novice. Another frequent structural mistake occurs when forming questions. Learners sometimes combine the affirmative-negative question structure with the question particle 吗 (ma). For example, saying '你有没有空吗？' (nǐ yǒu méi yǒu kòng ma?). This is grammatically redundant. You must choose one structure or the other: either '你有空吗？' (Do you have free time?) or '你有没有空？' (Do you have free time or not?). Mixing the two is a classic error that requires conscious practice to avoid.

Negation Error

Using 不 (bù) instead of 没 (méi) to negate 有 (yǒu). Always use 没空 (méi kòng), never 不空 (bù kòng).

Another significant area of confusion lies in the pronunciation and meaning of the character 空. As mentioned earlier, 空 has two pronunciations: kōng (first tone) and kòng (fourth tone). When it means 'empty' in a physical sense, like an empty box or the sky, it is kōng. When it means 'free time' or 'unoccupied space/time,' it is kòng. Learners often default to the first tone, saying 'yǒu kōng'. While native speakers will likely understand the intended meaning from context, it sounds distinctly foreign and incorrect. Furthermore, learners sometimes mistakenly use '有空' to describe physical emptiness. For example, trying to say 'This room is empty' by saying '这个房间有空'. This is incorrect. '有空' strictly refers to availability in time or schedule. To describe a physically empty room, you would use '空的' (kōng de) or say '这个房间没人' (This room has no people). Conflating the temporal 'empty space' (free time) with physical 'empty space' is a conceptual error that stems from direct translation from English, where 'free' or 'empty' can apply to both time and space.

Pronunciation & Context

Pronouncing 空 as kōng (1st tone) instead of kòng (4th tone), and mistakenly using 有空 to describe physical emptiness rather than temporal availability.

Finally, learners sometimes struggle with the placement of time words when using '有空'. In English, we often put the time at the end of the sentence: 'Are you free tomorrow?'. In Chinese, time words generally must come before the verb phrase. Therefore, '你明天有空吗？' (You tomorrow have free time?) is correct, while '你有空明天吗？' is grammatically incorrect and sounds very awkward. The time word acts as an adverbial modifier and must precede the action or state it modifies. Another minor but notable mistake is overusing '有空' in highly formal or written contexts where more sophisticated vocabulary would be appropriate. While '有空' is universally understood, in a formal business proposal or an academic paper, terms like '有时间' (have time) or '方便' (convenient) might carry a more appropriate register. However, for everyday communication, mastering the correct negation, pronunciation, question structure, and time word placement associated with '有空' will eliminate the vast majority of common errors and significantly improve conversational fluency.

Time Word Placement

Placing the time word after 有空 instead of before it. Always use Subject + Time + 有空.

The Chinese language offers several ways to express the concept of having free time or being available, and while 有空 is the most common, understanding its synonyms enriches a learner's vocabulary and conversational flexibility. The most direct and frequently used alternative is 有时间 (yǒu shíjiān), which literally translates to 'to have time.' In almost all everyday contexts, 有空 and 有时间 are perfectly interchangeable. You can ask '你明天有空吗？' or '你明天有时间吗？' with absolutely no change in meaning or tone. Both are casual, polite, and universally understood. However, a subtle distinction exists: 有空 emphasizes the *availability* or the 'empty slot' in a schedule, whereas 有时间 emphasizes the *possession of time* as a resource. For instance, if a task takes a long time, you might say '我没有时间做这个' (I don't have the time to do this), which sounds slightly more natural than '我没空做这个' (I don't have a free slot to do this), although both are acceptable. Understanding this nuance helps in choosing the most precise phrasing for a given situation.

有时间 (yǒu shíjiān)

Literally 'to have time'. Highly interchangeable with 有空, but slightly more focused on time as a resource rather than a gap in a schedule.

Another related term is 空闲 (kòngxián), which is an adjective or noun meaning 'idle,' 'free,' or 'leisure time.' While 有空 is a verb phrase (to have free time), 空闲 describes the state of being free. You might say '在空闲时间' (in one's free time) or '我很空闲' (I am very idle/free). 空闲 sounds slightly more formal and literary than the highly colloquial 有空. It is often used in written contexts or when discussing hobbies and leisure activities more abstractly. For example, a job interview might include the question '你空闲的时候喜欢做什么？' (What do you like to do in your free time?). Similarly, the phrase 没事 (méishì), literally 'no matter' or 'nothing to do,' is often used to imply availability. If someone asks what you are doing this weekend, replying '没事' (Nothing much) implies that you are free and open to suggestions. It is a more indirect way of saying 有空, focusing on the absence of obligations rather than the presence of free time.

空闲 (kòngxián)

More formal, often used as an adjective or noun for 'leisure time'. Used in phrases like 空闲时间 (free time).

In certain regional dialects or older colloquial speech, you might also hear 得空 (dékòng). This phrase means exactly the same thing as 有空—to manage to find time or to have free time. It is less common in standard Mandarin broadcasts or formal teaching materials but is widely understood, particularly in southern China and among older generations. For instance, '等我得空了再去找你' (I'll go find you when I get some free time). Finally, it is crucial to contrast these terms with words that denote convenience, such as 方便 (fāngbiàn). While asking '你方便吗？' (Is it convenient for you?) often implies asking if someone has time, it carries a broader meaning that includes physical convenience, privacy, and appropriateness, not just temporal availability. You might have free time (有空) but it might not be convenient (不方便) to take a call because you are in a quiet library. Understanding these subtle boundaries ensures that learners can navigate complex social situations with precision and cultural sensitivity.

方便 (fāngbiàn)

Means 'convenient'. Often overlaps with 有空 in scheduling, but includes broader aspects of appropriateness and comfort beyond just time.
