No. In 그 발송인, 그 is modifying a noun, so it means that or sometimes the in context.

• 그
  • noun = that ...
• So 그 발송인 = that sender / the sender

If 그 stood alone as a pronoun, it can sometimes be translated as he, but in modern Korean that usage is limited and often sounds like written translation style rather than natural everyday speech.

So in this sentence, 그 is definitely not he. It is describing 발송인.

발송인 means sender, especially in a formal or administrative sense.

It is commonly used for:

• mail
• packages
• shipping documents
• forms
• official labels

So depending on context, it could mean:

• the sender of a letter
• the sender of a package
• the shipper / dispatching party

It sounds more formal than casual everyday words like 보낸 사람 (the person who sent it).

은/는 is the topic marker, while 이/가 is the subject marker.

In this sentence:

• 발송인은 = as for the sender...
• 발송인이 = the sender as the grammatical subject with more focus

So 그 발송인은 거짓말을 했습니다 has a topic-comment feel:

• As for that sender, he/she lied
• That sender lied

If you said 그 발송인이 거짓말을 했습니다, it would feel more like:

• That sender is the one who lied
• stronger focus on who did it

Both can be grammatical, but the nuance changes.

Because Korean often expresses this idea with the noun 거짓말 (a lie / lies) plus the verb 하다 (to do).

So:

• 거짓말 = lie / falsehood
• 거짓말을 하다 = to lie / to tell a lie

This is a very common Korean pattern:

• noun + 하다

Here it is in the past polite form:

• 거짓말을 했습니다 = lied / told a lie

So even though English uses the single verb lie, Korean naturally uses 거짓말을 하다.

했습니다 is the formal polite past tense form of 하다.

Breakdown:

• 하다 = to do
• 했- = did
• -습니다 = formal polite sentence ending

So:

• 거짓말을 합니다 = lies / tells a lie
• 거짓말을 했습니다 = lied / told a lie

This level is polite and formal, often used in:

• news
• announcements
• workplace speech
• formal conversation
• written reports

을/를 is the object marker.

Here:

• 거짓말을 marks 거짓말 as the object of 하다

So literally:

• 거짓말을 하다 = to do a lie
• naturally: to lie / to tell a lie

Because 거짓말 ends in a consonant (ㄹ), it takes 을, not 를.

Compare:

• consonant ending → 을
• vowel ending → 를

Yes, very often.

In everyday Korean, the object marker can be omitted when the meaning is clear. So both are possible:

• 거짓말을 했습니다
• 거짓말했습니다

The version with 을 can sound a bit more explicit or careful. The version without it is very common in speech.

For a learner, it is good to know the full form first:

• 거짓말을 하다

Then later you will naturally notice that Koreans often drop 을/를 in conversation.

The basic order here is:

• 그 발송인은 = topic
• 거짓말을 = object
• 했습니다 = verb

So the standard Korean order is topic/subject + object + verb.

That said, Korean word order is more flexible than English because particles show each word’s role. For example, you may also see:

• 그 발송인은 거짓말을 했습니다.
• 거짓말을 그 발송인은 했습니다.

Both can be grammatical, but the second one sounds more marked or emphatic. For most situations, the original order is the most neutral and natural.

The verb usually comes at the end.

It can be translated either way depending on context.

Korean does not have articles like a and the in the same way English does, so translation depends on the situation.

• 그 발송인 often literally points to that sender
• In natural English, it may become the sender if the sender is already known in context

So if the meaning has already been established in the conversation, the sender may sound better in English, even though the Korean uses 그.

Yes. Korean does not mark gender here.

발송인 just means sender, so the sentence itself does not tell you whether the sender is:

• male
• female
• singular or sometimes contextually plural-like reference in translation

Usually the context tells you who the sender is. In English, you may need to choose:

• That sender lied
• He lied
• She lied
• They lied

But the Korean sentence itself stays neutral.

It is natural, but it sounds somewhat formal or technical.

You are likely to see 발송인 in:

• shipping contexts
• postal forms
• package labels
• official documents
• customer service language

In casual speech, people may more often say:

• 보낸 사람 = the person who sent it
• 보낸 분 = a polite way to say the sender

So 그 발송인은 거짓말을 했습니다 sounds a bit formal or report-like, not especially casual everyday conversation.

A few common less formal versions are:

• 그 발송인은 거짓말했어요.
• 그 발송인은 거짓말을 했어요.

These use -어요, which is polite but less formal than -습니다.

Very casual speech could be:

• 그 발송인은 거짓말했어.
• 그 발송인 거짓말했어.

The last one drops the topic marker too, which is common in casual conversation when the meaning is obvious.

Yes, a little.

거짓말을 하다 is the standard, direct way to say to lie or to tell a lie.

Depending on context, Korean might also use other expressions, such as:

• 속이다 = to deceive / trick
• 사실이 아니라고 말하다 = to say something untrue
• 허위 진술을 하다 = to make a false statement, very formal/legal

So 거짓말을 했습니다 is the straightforward, ordinary expression for lied. It does not necessarily imply a legal or highly technical kind of falsehood unless the wider context does.
