要 vs 会 (yào vs huì): intention vs prediction in future
Both 要 and 会 can refer to the future, but 要 expresses a planned intention or an imminent event (e.g., '明天我要去北京'), while 会 expresses a predicted likelihood or expected outcome based on reasoning or probability (e.g., '明天会下雨'). Choosing the wrong one can change the meaning from a firm plan to a vague forecast.
要 (yào) indicates a planned intention or an imminent action—something the speaker is determined to do or that is clearly about to happen based on current circumstances. 会 (huì) indicates a prediction or likelihood—something the speaker believes is probable based on reasoning or experience. 要 is stronger and more concrete; 会 is softer and more speculative. In negation, 不要 means 'don't want to / refuse', while 不会 means 'won't (likely not)'.
When to use each
Use 要 to express a planned intention, a scheduled event, or something that is about to happen imminently. It often carries a sense of determination or inevitability based on present evidence. For example, '我要吃饭' (I want to eat / I'm going to eat) implies a decision or hunger drive.
要 can also express a wish or need (e.g., '我要喝水' – I want to drink water), but in future contexts it signals a firm plan.
Use 会 for predictions, expectations, or assumptions about the future based on reasoning, probability, or natural consequences. It is not used for personal intentions or scheduled plans. For example, '他会来的' (He will come) expresses a belief that he will come, not necessarily a plan.
会 also means 'can' (ability learned), but in future contexts it marks likelihood.
At a glance
| 要 | 会 | |
|---|---|---|
| Intention vs Prediction | Planned intention or imminent event | Predicted likelihood |
| Certainty | Strong, often based on decision or immediate evidence | Weaker, based on reasoning or probability |
| Negation | 不要 (bù yào) = don't want to / refuse | 不会 (bù huì) = won't (likely not) |
| Weather statement (immediate vs general) | 明天要下雨 (Tomorrow it's going to rain – imminent or forecast with evidence) | 明天会下雨 (Tomorrow it will rain – general prediction) |
Examples
- 要明天我要去北京。Míngtiān wǒ yào qù Běijīng.I am going to Beijing tomorrow. (planned)Implies a definite plan, e.g., having a ticket.
- 会明天会下雨。Míngtiān huì xià yǔ.Tomorrow it will rain. (prediction)Based on forecast or experience.
- 要我要吃饭了。Wǒ yào chīfàn le.I'm going to eat now. (about to happen)The 了 adds immediacy.
- 会他不会来的。Tā bù huì lái de.He won't come. (prediction)Negation of likelihood.
- 要明天要下雨。Míngtiān yào xià yǔ.Tomorrow it's going to rain. (imminent or forecast)Natural in spoken Chinese; implies current evidence (dark clouds, etc.) or a clear forecast.
- 会我会去参加比赛。Wǒ huì qù cānjiā bǐsài.I will participate in the competition. (likely decision)Can be ambiguous; if it's a firm plan, 要 is preferred.
Common mistakes
- Using 会 to state a definite, planned intention: '我会去上海明天' (when you have a ticket) – use 要.
- Using 要 for a general prediction without immediate evidence: '明天要很冷' (when just speculating) – use 会.
- Forming refusal with 会: '我会不去' is ungrammatical; use '我不要去' or '我不去'.
- Confusing negation: '不要' means 'don't want' (refusal), not 'will not' (prediction); for 'will not' use '不会'.
FAQ
- When do I use 要 vs 会 for future actions?
- Use 要 for things you plan to do or that are about to happen (strong intention). Use 会 for predictions or assumptions (likelihood). For example, '我要去商店' (I'm going to the store) vs '他会去商店' (He will probably go to the store).
- Can 要 and 会 be used interchangeably?
- No, they have different nuances. 要 implies a planned intention or imminent action, while 会 implies a prediction. In some contexts (e.g., '明天会下雨' vs '明天要下雨'), both are acceptable but 要 suggests current evidence or a more definite forecast.
- What about negation: 不要 vs 不会?
- 不要 (bú yào) means 'not want to' or 'don't' (refusal), e.g., '我不要去' = I don't want to go. 不会 (bú huì) means 'will not' (prediction), e.g., '他不会来' = He won't come (I think). They are not interchangeable.
