hết vs xong — Expressing Completion and Finishing

Quick Answer

In Vietnamese, both hết and xong relate to completion, but they emphasize different aspects. Hết typically means something is depleted, used up, or entirely gone, focusing on the state of a resource or quantity. Xong, on the other hand, means a task, process, or action has been completed, focusing on the conclusion of an activity.

Detailed Explanation

Understanding the nuance between hết and xong is crucial for expressing completion accurately in Vietnamese. While both translate to 'finished' or 'completed' in many contexts, their core meanings and usages diverge.

Hết (Hán-Việt: 竭 - kiệt, meaning exhausted; or 訖 - ngật, meaning completed) primarily conveys the idea of something being entirely consumed, depleted, or reaching its end. Think of it as 'all gone' or 'nothing left'. It can refer to physical resources (money, food, water), abstract quantities (time, energy), or the complete extent of something (eating an entire cake, reading a whole book). When hết follows a verb, it means to complete the action fully, leaving nothing undone or remaining of the object. For example, ăn hết means to eat all of something, leaving none.

Xong (Hán-Việt: 成 - thành, meaning success, completion; or 終 - chung, meaning end) focuses on the completion of an action, task, or process. It indicates that an activity has reached its conclusion and is now 'done'. It doesn't necessarily imply depletion or consumption, but rather the state of an action being finalized. For instance, làm xong means to finish doing a task, and nấu xong means to finish cooking a meal. The emphasis is on the successful termination of the process, rather than the exhaustion of resources involved.

In summary, use hết when you want to express that something is depleted, consumed, or completely used up. Use xong when you want to express that a task or action has been brought to its conclusion.

Common Mistakes

Mistake 1 — Confusing task completion with resource depletion

Learners often use xong when they mean a resource is used up, or hết when they mean a task is done.

❌ Tôi đã làm hết bài tập rồi.

✅ Tôi đã làm xong bài tập rồi.

Why it's wrong and how to fix it: "Làm bài tập" is a task. When you complete a task, you use xong. "Làm hết bài tập" would imply exhausting all possible homework, which is usually not the intended meaning. If you mean you completed all the assigned homework, then xong is correct. If you meant to emphasize that you used up all your energy doing homework, then hết sức (out of strength) would be more appropriate.

Mistake 2 — Using hết for task completion when the focus isn't depletion

While "hết" can mean "completely" when used with a verb (e.g., đọc hết sách), it's specifically about the entirety or exhaustion of the object. "Xong" is about the completion of the action itself.

❌ Khi nào bạn nấu hết bữa tối?

✅ Khi nào bạn nấu xong bữa tối?

Why it's wrong and how to fix it: "Nấu bữa tối" is a process. To ask about the completion of this process, xong is the correct word. "Nấu hết bữa tối" would imply cooking all possible dinner, or exhausting all ingredients, which is not what the question intends. The focus is on when the cooking process will be finished.

Mistake 3 — Using xong when a quantity is depleted

It's incorrect to use xong to describe running out of something like money or time.

❌ Tôi xong tiền rồi.

✅ Tôi hết tiền rồi.

Why it's wrong and how to fix it: "Tiền" (money) is a resource. When a resource is gone or depleted, you use hết. "Xong tiền" doesn't make sense as money is not a task to be completed.
