Consider a routine Korean business sentence:

검토 후 회신드리겠습니다.

Literal: “After reviewing, [I/we] will reply.”

A translator renders it as:

We will review it and get back to you.

The English is grammatical. The meaning is plausible. On the surface, nothing is missing.

But one question remains: who exactly is “we”?

Korean frequently omits subjects when the participants can recover them from context. English often requires the translator to supply one. The moment we choose “I,” “we,” or a named party, we may assign responsibility that the source never stated explicitly.

This small example illustrates a larger problem:

A sentence can be perfectly correct English and still be the wrong translation.

Correctness is necessary, but it is not the final test. A professional translation must also preserve, as far as the languages allow, who is acting, what action is expected, how strongly something is being stated, and how the message functions between the people involved.

Korean-to-English translation makes these issues particularly visible, but the principle applies across language pairs.

1. Agency: Who did the translation make responsible?

Let’s revisit the opening example:

검토 후 회신드리겠습니다.

Literal: “After reviewing, [I/we] will reply.”

Depending on context, several English versions may be possible:

I will review it and get back to you.

We will review it and get back to you.

We will review this internally and get back to you.

All three are natural English. All three could be correct.

But they do not make the same commitment.

“I” assigns responsibility to an individual. “We” assigns it to a group or organization. “Internally” implies a process involving others.

The Korean source may leave all of this unstated.

The translator therefore faces a decision created not by poor wording in the source, but by a structural difference between the two languages. English may force an explicit choice where Korean did not.

The useful question is no longer only:

What does this sentence mean?

It is also:

What responsibility does my translation assign, and did the source assign it?

This is an agency question.

Agency errors are easy to miss because the English may sound completely natural. Fluency can hide the fact that the translator has quietly introduced an actor.

2. Action: Is the reader left guessing what to do next?

Consider another extremely common Korean expression:

확인 부탁드립니다.

Literal: “I ask/request that you check/confirm.”

A plausible translation is:

Please check.

Again, there is nothing grammatically wrong with it.

But what is the recipient supposed to check?

Depending on context, 확인 may mean:

• verify that information is correct,


• confirm receipt,


• review a document,


• check whether an action has been completed,


• or acknowledge that something has been seen.

Korean can often rely on shared context to supply the missing detail. English may benefit from making the expected action more explicit.

The appropriate translation might therefore be:

Could you confirm that the information is correct?

or:

Please let us know once you have reviewed the document.

or simply:

Could you confirm receipt?

None of these is inherently better than “Please check.” Context determines the right choice.

The important point is that a translation can reproduce the apparent meaning of a source expression while leaving the target reader less certain about what to do next.

This is an action question:

Will the target reader understand the expected next step as reliably as the source reader would?

That matters because professional communication is rarely written merely to describe something. It usually exists because somebody is expected to do something after reading it.

3. Commitment: Did the translation change the strength of the message?

Now consider:

논의가 필요할 것 같습니다.

Literal: “It seems that discussion will be necessary.”

The literal rendering is perfectly possible English.

But imagine that the sentence appears in an email where the writer is raising a concern before a project proceeds. In Korean professional communication, expressions such as -것 같습니다 can soften a recommendation, objection, or potentially uncomfortable statement.

In that context, the practical meaning may be closer to:

I think we should discuss this before proceeding.

The second version is structurally less similar to the Korean, yet it may reproduce the writer’s actual stance more accurately.

This does not mean that Korean indirectness should routinely be converted into direct English. That would simply create another distortion.

Here, the translator must distinguish between two very different realities:

Is the writer genuinely uncertain?

Or is the writer reasonably certain but using linguistic softening to manage the interpersonal effect of the statement?

If genuine uncertainty is present, it must remain.

But if a translator mechanically reproduces every Korean hedge in English, a clear recommendation may become a hesitant suggestion.

The reverse can also happen. Removing a hedge too aggressively may turn a cautious observation into a firm conclusion.

This is a commitment question:

Has the translation made the writer more certain, less certain, more obligated, or less obligated than the source?

4. Interpersonal force: Did the relationship change in translation?

Politeness does not transfer word for word.

A form that sounds appropriately deferential in Korean may sound distant, vague, bureaucratic, or excessively formal when reproduced too literally in English.

Conversely, an English sentence that looks more direct on the page may create a social effect closer to that of the Korean original.

This is why “make it sound natural” is not a sufficient instruction.

Natural for whom?

In what relationship?

For what purpose?

A request from a customer to a vendor does not function like an instruction from a supervisor. A regulatory letter does not operate like an email between colleagues. The same Korean expression may require different English choices depending on the relationship surrounding it.

The translator therefore needs to ask whether the interpersonal force has shifted.

Did a respectful request become a command?

Did a firm instruction become a tentative suggestion?

Did professional restraint become vagueness?

Did ordinary courtesy become exaggerated deference?

These can all be translation errors even when no dictionary meaning is obviously wrong.

Adding a functional pass to ordinary QA

Traditional QA remains essential.

Terminology, numbers, omissions, grammar, consistency, formatting, and source-target correspondence all need to be checked.

But those checks operate mainly on what is present in the text. They are less effective at detecting changes in what the communication causes the reader to understand or do.

A useful final QA pass is therefore to examine the translation through four lenses:

• Agency: Has the translation changed who appears to be acting or responsible?


• Action: Is the expected next step as clear to the target reader as it was to the source reader?


• Commitment: Has the translation strengthened or weakened the writer’s position?


• Interpersonal force: Has the relationship between the participants shifted through changes in directness, politeness, distance, or authority?

These are not replacements for linguistic QA. They catch a different class of error.

A terminology checker cannot tell us whether “we” assigns responsibility to the wrong party.

A grammar checker cannot tell us whether “Please check” leaves the requested action unnecessarily vague.

A consistency checker cannot determine whether repeated hedging has made a firm recommendation sound uncertain.

The English may be flawless.

The communication may still have changed.

Functional accuracy is not free rewriting

There is an important boundary here.

Once translators begin talking about communicative function, it is easy to conclude that anything can be rewritten in the name of naturalness.

That would be a mistake.

A translator is not entitled to repair weak logic, eliminate intentional ambiguity, strengthen a cautious statement, or assign responsibility that the source deliberately leaves unspecified.

Sometimes ambiguity is information.

Sometimes indirectness is deliberate.

Sometimes awkwardness belongs to the source.

And sometimes the correct professional response is to query or flag a problem rather than silently resolve it.

The goal is not to make the target text better than the source.

The goal is to avoid creating new differences simply because the two languages package information differently.

That requires intervention in some places and restraint in others.

Knowing which is which is part of professional judgment.

It also explains why translators sometimes need to ask questions that may seem unnecessary to someone looking only at the words. A question about who performs an action, how firm a statement is, or what the recipient is expected to confirm may be essential to preserving the source rather than departing from it.

One final read

There is a simple way to test for these problems.

After completing the usual bilingual review, temporarily stop looking at the source.

Read the translation as the target reader will read it.

Then ask:

What does this reader understand they are being told, asked, promised, permitted, or required to do?

Only then return to the source.

Would the intended source reader have reached substantially the same understanding?

This final comparison can expose problems that disappear during sentence-by-sentence review. Every segment may be individually defensible while the completed translation assigns the wrong responsibility, weakens the wrong statement, or obscures the expected action.

Korean and English provide particularly clear examples because they differ greatly in what can remain implicit and in how interpersonal relationships are encoded.

But every language pair has its own version of the problem.

Every language leaves some information unstated because its users know how to recover it. Every language also requires speakers to make distinctions that another language allows them to avoid.

Translation happens at that boundary.

That is why the final question should not be only:

Is this English correct?

It should also be:

If the reader sees only this translation, will they understand who is doing what, with what degree of commitment, and with substantially the same communicative force as the reader of the source?

If the answer is no, perfectly correct English may still be the wrong translation.
