가 is the subject marker. It marks 친구 as the person who is getting married.

So in 친구가 다음 달에 결혼해요, 친구가 means the friend is the one who will get married.

A learner often compares 가 with 는:

• 친구가 다음 달에 결혼해요
  = My friend is getting married next month / It’s my friend who is getting married next month
• 친구는 다음 달에 결혼해요
  = As for my friend, they’re getting married next month

Using 는 would make 친구 more of the topic, while 가 simply identifies the subject.

Yes, you can.

The difference is mainly in focus and context:

• 친구가 다음 달에 결혼해요
  sounds neutral or slightly focuses on who is getting married.
• 친구는 다음 달에 결혼해요
  sounds like as for my friend..., and may imply contrast or a known topic.

For example:

• 저는 아직 안 해요. 친구는 다음 달에 결혼해요.
  I’m not getting married yet. My friend is getting married next month.

So both are possible, but 가 and 는 are not identical.

다음 달 means next month.

Breakdown:

• 다음 = next, following
• 달 = month

So 다음 달 is literally the next month.

In everyday Korean, this is a very common way to say next month.

에 marks a point in time when something happens.

So:

• 다음 달에 = next month
• more literally: at/in next month

In Korean, 에 is commonly used with specific time expressions like:

• 월요일에 = on Monday
• 3시에 = at 3 o’clock
• 내년에 = next year
• 다음 달에 = next month

It shows when the marriage will happen.

This is a very common question.

In Korean, the present tense is often used for a planned or scheduled future action, especially when the time is already clear from context.

So:

• 친구가 다음 달에 결혼해요
  literally looks like My friend marries next month
• but naturally means My friend is getting married next month / My friend will get married next month

Because 다음 달에 already shows the future, Korean does not need a separate future form here.

You could also say a future-looking form in some contexts, but 결혼해요 is completely natural.

The dictionary form is 결혼하다, which means to marry or to get married.

It is made of:

• 결혼 = marriage
• 하다 = to do

So 결혼하다 literally comes from to do marriage, but in natural English it means to get married.

The polite present form is:

• 결혼해요

This comes from contracting:

• 결혼하 + 여요 → 결혼해요

Yes, but the difference is small.

• 결혼해요 is the more common, compact form.
• 결혼을 해요 is also grammatical because 결혼 can function as a noun and take 을.

In everyday speech, 결혼해요 is usually more natural.

So for this sentence, 친구가 다음 달에 결혼해요 is the normal choice.

친구 is gender-neutral. It can mean:

• a male friend
• a female friend

The sentence itself does not tell you the friend’s gender.

If Korean speakers want to specify, they can add more information, but 친구 alone does not do that.

Korean often leaves out words that are understood from context.

In English, you often say my friend, but in Korean just 친구 is very common if it is already clear whose friend you mean.

So:

• 친구가 다음 달에 결혼해요
  can naturally mean My friend is getting married next month

Korean does not always state possessives like my, your, or his/her when they are obvious.

Yes, very often.

If the listener already knows who you are talking about, Korean can omit the subject:

• 다음 달에 결혼해요.
  = (My friend) is getting married next month.

This is very natural in conversation.

Korean drops subjects much more often than English does, as long as the meaning is clear from context.

Not completely.

The basic sentence is:

• 친구가 다음 달에 결혼해요

But Korean word order is more flexible than English because particles show each word’s role.

You could also say:

• 다음 달에 친구가 결혼해요

This still means the same thing. The difference is mostly about what is emphasized first.

However, the verb usually comes at the end of the sentence in Korean, so 결혼해요 stays at the end.

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

It is very common in everyday conversation and is appropriate in many situations.

Compare:

• 결혼해 = casual, plain speech
• 결혼해요 = polite everyday speech
• 결혼합니다 = more formal

So this sentence sounds polite and natural for normal conversation.

In many cases, 결혼하다 is best understood as to get married.

So:

• 친구가 다음 달에 결혼해요
  means My friend is getting married next month

If you want to mention the person they are marrying, Korean can express that too, but in this sentence the focus is simply on the event of marriage itself.

So here, the most natural interpretation is to get married, not specifically to marry someone.
