-이/가 is the subject marker. Here, 발송인 means sender or shipper, and 발송인이 means the sender as the subject of the sentence.

So in this sentence:

• 발송인이 = the sender (subject)
• 운송장을 = the shipping label / waybill (object of 확인하다)
• 물건을 = the item/package (object of 발송하다)

A learner might wonder why it is not 발송인은. Both are possible in different contexts, but they have different feelings:

• 발송인이 focuses on who did the action
• 발송인은 would sound more like as for the sender...

In a plain factual sentence like this, -이/가 is very natural.

Yes, 발송인 means sender, shipper, or the person/company sending the item.

It is made from:

• 발송 = dispatch, shipment
• 인 = person

So literally it is something like dispatch person, but in natural English it is sender or shipper.

This is a formal/logistics word. In everyday conversation, people might more often use expressions built around 보내다 (to send) rather than 발송인.

운송장 is a shipping/logistics term. It usually means:

• waybill
• shipping label
• delivery invoice
• sometimes tracking slip, depending on context

In practical everyday translation, shipping label is often the easiest way to understand it.

It is made from:

• 운송 = transport, shipping
• 장 = document/sheet

So 운송장을 확인하다 means to check the shipping document/label.

Because there are two verbs, and each verb has its own object.

The sentence has these two action parts:

1. 운송장을 다시 확인하고
   = checked the shipping label again

2. 물건을 발송했습니다
   = shipped the item

So:

• 운송장을 goes with 확인하고
• 물건을 goes with 발송했습니다

This is very common in Korean. A sentence can include multiple verbs, and each verb can have its own object.

다시 means again.

So 운송장을 다시 확인하고 means:

• checked the shipping label again
• or rechecked the shipping label

In Korean, 다시 usually goes before the verb it modifies, so here it comes before 확인하고.

Compare:

• 다시 확인하다 = to check again
• 다시 보내다 = to send again

확인하고 comes from 확인하다 (to check / confirm / verify) plus -고, which connects actions.

So 확인하고 means something like:

• check and...
• after checking...
• having checked...

In this sentence, it shows that the sender checked the shipping label again and then shipped the item.

The -고 form often links actions in sequence, especially when one action happens before the next one.

So the overall flow is:

1. recheck the shipping label
2. ship the item

Not always, but very often that is how it is understood, especially when the actions are naturally sequential like in this sentence.

-고 can simply mean and, connecting two actions. But in many real sentences, context makes it feel like:

• and then
• after doing that

Here, 운송장을 다시 확인하고 물건을 발송했습니다 strongly suggests:

• The sender checked the shipping label again and then sent the package.

Because checking the label is logically something you do before shipment.

Because they are related words from the same Sino-Korean root.

• 발송인 = sender / shipper
• 발송했습니다 = shipped / dispatched

This kind of repetition is normal in Korean, especially in formal or administrative language. It may sound a little repetitive in English, but in Korean it is not strange.

It is similar to saying something like:

• The shipper checked the waybill again and dispatched the goods.

So yes, the same root appears twice, but that is perfectly natural in this style.

Both can mean to send, but the tone is different.

• 보내다 = general everyday to send
• 발송하다 = more formal, business/logistics to dispatch / ship

So:

• 친구에게 메시지를 보냈어요. = I sent a message to a friend.
• 물건을 발송했습니다. = The item was shipped/dispatched.

In this sentence, 발송하다 is used because the context is shipping goods, labels, and logistics.

발송했습니다 is:

• past tense
• formal polite style (습니다체)

It comes from:

• dictionary form: 발송하다
• past: 발송했다
• formal polite past: 발송했습니다

So it means shipped, dispatched, or has shipped depending on context.

Some related forms:

• 발송합니다 = ships / will ship / am shipping (formal polite)
• 발송했어요 = shipped (polite, less formal)
• 발송했다 = shipped (plain form)

Korean word order is fairly flexible because particles show each word’s role. So the exact order can change more easily than in English.

The original sentence is:

• 발송인이 운송장을 다시 확인하고 물건을 발송했습니다.

This is very natural. But you could also see variations like:

• 발송인이 물건을 발송하기 전에 운송장을 다시 확인했습니다.
  = The sender checked the shipping label again before shipping the item.

That said, not every rearrangement sounds equally natural. The given version is smooth because it presents the actions in a clear sequence:

1. check the shipping label again
2. ship the item

So while Korean allows flexibility, the original order is probably the best default here.

Yes. Sent the item is possible and often understandable. But because the sentence includes formal logistics words like 발송인 and 운송장, shipped the item or dispatched the item is usually a better match in tone.

So the nuance is:

• sent the item = understandable, a bit more general
• shipped/dispatched the item = better fit for this formal shipping context

It can mean both, depending on context.

• check = look over something
• confirm / verify = make sure it is correct

In this sentence, 운송장을 다시 확인하다 suggests something like:

• check the shipping label again
• verify the shipping label again

Because the sender is likely making sure the shipping information is correct before sending the item.

So check is the easiest basic translation, but verify is also a good nuance here.
