에 marks the time when something happens. In this sentence, 아침에 means in the morning or at morning time.

So the pattern is:

• time expression + 에

Examples:

• 아침에 = in the morning
• 저녁에 = in the evening
• 월요일에 = on Monday

With time words, 에 is very often used, though in some cases it can be omitted in casual speech.

을 is the object particle. It marks 국 as the thing being boiled/cooked.

So here:

• 국 = soup
• 을 = object marker
• 국을 = soup, as the object of the verb

Korean uses:

• 을 after a noun ending in a consonant
• 를 after a noun ending in a vowel

Since 국 ends in the consonant ㄱ, it becomes 국을.

Because this sentence uses the transitive verb 끓이다, which means to boil/cook something.

• 끓다 = to boil
  
  • something boils on its own
• 끓이다 = to boil/cook something
  
  • someone boils something

In this sentence, there is an object, 국을, so the verb must be the transitive one: 끓이다.

Compare:

• 물이 끓어요. = The water boils.
• 국을 끓여요. = I/you/he/she boil(s) soup.

So 끓어요 would match 끓다, not 끓이다.

The dictionary form is 끓이다.

To make the polite present form:

• 끓이다
• stem: 끓이-
• -어요 attaches
• 이 + 어요 becomes 여요

So:

• 끓이다 → 끓이어요 → 끓여요

This is a very common pattern for verbs ending in -이다.

It is omitted.

Korean often leaves out the subject when it is already understood from context. So 아침에 국을 끓여요 could mean:

• I boil soup in the morning.
• We boil soup in the morning.
• He/She boils soup in the morning.

The exact subject depends on the situation. In beginner examples, English often supplies I, but the Korean sentence itself does not explicitly say that.

It can mean different things depending on context.

-아요 / -어요 present tense in Korean is flexible. It can describe:

• a habitual action
  
  • I boil soup in the morning
• a present action
  
  • I’m boiling soup this morning
• sometimes even a near-future action, depending on context

Without more context, many learners will understand this as a general or habitual statement: I boil soup in the morning.

Not completely. Korean word order is more flexible than English, as long as the particles make the roles clear.

This sentence has a very natural order:

• 아침에 국을 끓여요
• time + object + verb

But you could also say:

• 국을 아침에 끓여요

That is still grammatical. However, the original version sounds very natural because it starts by setting the time first.

The one part that usually stays at the end is the verb:

• 끓여요 comes last.

끓여요 is in the polite informal style, often called the -요 form.

It is:

• polite
• natural in everyday conversation
• very common in spoken Korean

It is less formal than 끓입니다, but more polite than plain casual forms like 끓여.

So this is a good standard form for daily speech.

Yes, but the meaning changes slightly.

• 아침에 = in the morning
• 아침마다 = every morning

So:

• 아침에 국을 끓여요 = I boil soup in the morning.
• 아침마다 국을 끓여요 = I boil soup every morning.

If you want to emphasize repetition or habit, 마다 is often a better choice.

You can add 은/는 if you want extra topic contrast or emphasis, but it is not necessary.

The basic sentence is simply:

• 아침에 국을 끓여요

If you say:

• 아침에는 국을 끓여요

then 아침에는 can sound more like:

• In the morning, I boil soup
• possibly with contrast, such as but at night I eat something else

So:

• 아침에 = neutral time expression
• 아침에는 = time expression with topic/contrast nuance

The version without 는 is the more neutral basic sentence.
