Korean often puts time expressions near the beginning of the sentence. So 오늘 means today, and placing it first sets the time background for the whole sentence.

That said, Korean word order is fairly flexible because particles show each word’s role. You could move 오늘 elsewhere and still be understood, but putting it early is very natural.

For example:

• 오늘 우체국에서 친구에게 소포를 보냈어요.
• 우체국에서 오늘 친구에게 소포를 보냈어요.

Both are possible, but the first one sounds very standard and neutral.

우체국 means post office, and 에서 is a particle that often marks the place where an action happens.

So:

• 우체국 = post office
• 우체국에서 = at the post office / from the post office in the sense of the action taking place there

In this sentence, the action of sending happened at the post office, so 에서 is the natural choice.

A useful contrast:

• 에서 = where an action happens
• 에 = location/destination/time, depending on context

For example:

• 학교에서 공부해요. = I study at school.
• 학교에 가요. = I go to school.

친구 means friend, and 에게 marks the recipient of an action, especially when something is given, sent, told, or shown to someone.

So:

• 친구 = friend
• 친구에게 = to a friend / to my friend

In this sentence, the parcel is being sent to the friend, so 에게 marks that person.

Common verbs that often use 에게 include:

• 주다 = to give
• 보내다 = to send
• 말하다 = to speak/tell
• 보여주다 = to show

Yes. 친구에게 and 친구한테 both mean to a friend.

The difference is mostly one of style:

• 에게 = a bit more neutral or slightly more formal/written
• 한테 = more conversational and casual

So these are both natural:

• 오늘 우체국에서 친구에게 소포를 보냈어요.
• 오늘 우체국에서 친구한테 소포를 보냈어요.

Since the sentence ends with -어요, which is polite but everyday speech, either one works well.

소포 means parcel or package, and 를 is the object particle. It marks what is being acted on.

So:

• 소포 = parcel
• 소포를 = the parcel as the object of sent

In English, word order tells us the object: I sent a parcel.
In Korean, the particle 를 makes that role clear.

You may also see 을 instead of 를. Which one you use depends on the final sound of the noun:

• after a consonant: 을
• after a vowel: 를

Since 소포 ends in a vowel sound, it takes 를.

보냈어요 comes from the verb 보내다, which means to send.

This form is:

• past tense
• polite style

Breakdown:

• 보내다 = to send
• past stem becomes 보냈-
• polite ending -어요
• 보냈어요 = sent / I sent

So the whole sentence means something like:

• I sent a parcel to a friend at the post office today.

Great question. Historically, the past tense is made with -았/었-, so from 보내다 you could think of it as:

• 보내 + 었어요

But in actual Korean, this contracts:

• 보내었어요 → 보냈어요

This kind of contraction is very common and natural.

So learners often memorize the final result:

• 보내다 → 보냈어요

Other similar examples:

• 만나다 → 만났어요
• 세우다 → 세웠어요
• 주다 → 줬어요 from 주었어요

Korean very often omits the subject when it is clear from context.

In English, you usually need to say:

• I sent a parcel...

But in Korean, if the speaker is obviously talking about their own action, the subject 저는 or 나는 is often left out.

So this sentence naturally implies:

• (I) sent a parcel to a friend at the post office today.

If you wanted to include the subject, you could say:

• 저는 오늘 우체국에서 친구에게 소포를 보냈어요.

But leaving it out is very normal.

Korean word order is more flexible than English, because particles show the grammatical roles.

The basic verb-final pattern stays the same, but the earlier parts can move around:

• 오늘 우체국에서 친구에게 소포를 보냈어요.
• 오늘 친구에게 우체국에서 소포를 보냈어요.
• 친구에게 오늘 우체국에서 소포를 보냈어요.

These are all understandable. However, some orders sound more natural than others depending on what you want to emphasize.

A very common neutral pattern is:

time + place + recipient + object + verb

which is exactly what this sentence uses.

소포 specifically means a parcel or postal package, especially something sent through the mail.

It is a good match here because the sentence is about sending something at the post office.

Related words:

• 소포 = parcel, postal package
• 상자 = box
• 짐 = baggage, load, stuff
• 택배 = delivery service / courier package, often used for modern home delivery

So 소포 fits especially well in a post-office context.

The ending -어요 is part of the polite informal style in Korean. It is one of the most common endings in everyday conversation.

So 보냈어요 is polite and natural for many situations:

• talking to someone you don’t know well
• talking to a teacher or coworker
• speaking respectfully in normal daily life

It is less formal than -습니다 style, but more polite than casual plain speech.

Compare:

• 보냈어요 = polite everyday speech
• 보냈습니다 = more formal
• 보냈어 = casual, used with close friends or younger people

Yes, in English translation it may sound like from the post office, but grammatically 에서 is mainly marking the place where the action occurs.

So the Korean focus is not exactly the same as an English from of origin. It is more like:

• at the post office, I sent...

But in natural English, we often translate it as:

• I sent a parcel from the post office...

because that sounds smoother.

So the Korean grammar is about the location of the action, even if the English translation sometimes uses from.

In casual speech, you would usually change the ending -어요 to -어/아 style:

• 오늘 우체국에서 친구에게 소포를 보냈어.

You could also use 친구한테 for an even more conversational feel:

• 오늘 우체국에서 친구한테 소포를 보냈어.

Both mean the same thing, but they are suitable only with someone you can speak casually to.

Yes, the spelling and the sound are not always exactly what an English speaker expects.

보냈어요 is often pronounced close to:

• bo-nae-sseo-yo

The ㅆ gives the past-tense ss sound, and the whole form flows together naturally in speech.

Learners sometimes want to pronounce each part too separately, but in normal speech it sounds smooth and connected.

It helps to think of it as one chunk:

• 보냈어요

rather than trying to say every historical piece of the conjugation individually.
