저는 is 저 + 는.

• 저 = I in a humble/polite form
• 는 = topic particle

So 저는 means something like as for me or I with a polite tone.

Korean often uses 저 instead of 나 when speaking politely. Since the sentence ends in the polite form -어요, using 저는 matches that level of politeness well.

-는 marks the topic of the sentence.

In this sentence, 저는 tells us that the speaker is the person being talked about: as for me, ...

This is slightly different from the subject particle -이/가. A learner-friendly way to think about it is:

• 저는 = as for me / I
• 제가 = I with more focus or contrast

So 저는 엄마에게 바로 전화했어요 can feel like As for me, I called my mom right away.

Because 엄마 is the person receiving the phone call, not the direct object in the English sense.

The particle -에게 means to someone.

So:

• 엄마에게 = to Mom
• 전화했어요 = called / made a phone call

Together, 엄마에게 전화했어요 literally works like made a phone call to Mom.

If you used 엄마를, it would sound unnatural here.

Both can mean to someone.

• 엄마에게 = a bit more neutral or slightly more formal
• 엄마한테 = more conversational and casual

So both of these are possible:

• 엄마에게 바로 전화했어요
• 엄마한테 바로 전화했어요

They mean basically the same thing here.

There is also 께, which is the honorific version used for someone deserving extra respect:

• 어머니께 전화했어요 = I called Mother / I called my mother in a respectful way

Here, 바로 means right away, immediately, or straight/directly depending on context.

In this sentence, the most natural sense is:

• 바로 전화했어요 = called right away

So it adds the idea that the speaker did not wait.

Because 바로 is modifying the action 전화했어요.

In Korean, adverbs usually come before the verb they describe. So:

• 바로 전화했어요 = called immediately

You may also see slight word-order changes like:

• 저는 바로 엄마에게 전화했어요
• 저는 엄마에게 바로 전화했어요

Both are natural. The exact placement can slightly affect what feels emphasized, but the meaning stays very similar.

It comes from the verb 전화하다, which means to call or to make a phone call.

Breakdown:

• 전화 = phone call
• 하다 = to do

So 전화하다 literally means to do a phone call.

Then it changes like this:

• 전화하다
• 전화했어요 = past tense polite form

The 했어요 part is the past form of 하다:

• 해요 = do
• 했어요 = did

So 전화했어요 means called.

Good question. With many noun + 하다 verbs, Korean can express them in two common ways:

• 전화했어요
• 전화를 했어요

Both are used and both mean called.

Why? Because 전화하다 has become a very common combined verb. So speakers often just say 전화했어요 without separating 전화 and adding -를.

You may hear both, but 전화했어요 is extremely natural.

Yes. Very often, Korean leaves out subjects when they are clear from context.

So in a normal conversation, people might simply say:

• 엄마에게 바로 전화했어요.

That still naturally means I called Mom right away, if it is obvious that the speaker is talking about themselves.

Korean drops pronouns much more often than English does.

Not always. 엄마 is very common and natural in everyday speech, especially when talking casually about your own mom.

But in more polite or formal situations, speakers may prefer:

• 어머니 = mother / mom, more polite

So depending on tone, you might also hear:

• 저는 어머니께 바로 전화했어요.

That sounds more respectful and formal than 엄마에게.

했어요 is pronounced more like 해써요.

So:

• 전화했어요 sounds roughly like 전화해써요

This happens because the consonant sound in 했 is pronounced as a tense ㅆ sound in connected speech.

A rough full pronunciation of the sentence is:

• 저는 엄마에게 바로 전화해써요

Not exact English spelling, of course, but that is a helpful approximation for learners.
