먼저 means first or before anything else.

In this sentence, it tells you that writing your name is the first step:

• 먼저 = first
• 이 신청서에 이름을 정확하게 써요 = write your name accurately on this application form

So the overall feeling is: First, write your name accurately on this application form.

Because 에 marks the place/location where the writing goes.

• 이 신청서에 = on this application form
• 이 신청서를 would make application form the direct object, which would sound like write the application form rather than write on the application form

With 쓰다 (to write), Korean often marks:

• the thing being written with 을/를
• the place/surface with 에

So here:

• 이름을 = the thing you write
• 신청서에 = the place where you write it

Because 이름 is the direct object of 쓰다.

You are writing the name, so:

• 이름 = name
• 이름을 = name + object marker

This tells us what is being written.

So the structure is:

• 이 신청서에 = on this application form
• 이름을 = the name
• 정확하게 써요 = write accurately

정확하게 means accurately, correctly, or exactly.

It comes from:

• 정확하다 = to be accurate/correct
• 정확하게 = accurately

In this sentence, it means you should write your name correctly and clearly, without mistakes.

A natural English translation could be:

• Write your name accurately
• Write your name correctly
• Make sure you write your name exactly right

This is because 쓰다 is an ㅡ-irregular-style contraction pattern in conjugation.

The dictionary form is:

• 쓰다 = to write

To make the polite present form, you start from the stem:

• 쓰-

When -어요 is added, the ㅡ drops:

• 쓰 + 어요 → 써요

So:

• 쓰다 → 써요

This same pattern happens with many ㅡ-ending verbs/adjectives:

• 크다 → 커요
• 바쁘다 → 바빠요
• 쓰다 → 써요

Yes, it functions like a polite instruction or polite command.

Even though -아요/어요 is often taught as the polite present tense, in context it can also be used for:

• instructions
• directions
• gentle commands

So 써요 here can mean:

• write
• please write

It sounds polite, not harsh.

If you wanted a more explicitly formal instruction, you might also see:

• 쓰세요 = please write
• 작성하세요 = please fill out / write

But 써요 is very natural in spoken instructions depending on context.

Because Korean often leaves out the subject when it is obvious from context.

In this case, the implied subject is probably you:

• (당신은) 먼저 이 신청서에 이름을 정확하게 써요.

But Korean usually does not say 당신은 in situations like this, because it sounds unnecessary or sometimes awkward.

So the sentence naturally just gives the instruction without stating the subject.

The basic order is:

먼저 + 이 신청서에 + 이름을 + 정확하게 + 써요

You can think of it as:

• 먼저 = first
• 이 신청서에 = on this application form
• 이름을 = your name
• 정확하게 = accurately
• 써요 = write

A very literal gloss would be:

First, on this application form, name accurately write.

This reflects normal Korean word order, where the verb usually comes at the end.

By itself, 이름을 써요 literally means write the name / write a name / write one’s name, depending on context.

In this sentence, because it is about an application form, the natural meaning is write your name.

Korean often relies on context for things that English makes explicit. So although your is not stated, it is understood.

Yes. Korean has several adverbs that could be used, but they have slightly different nuances.

For example:

• 정확하게 = accurately, exactly
• 바르게 = correctly, properly
• 또박또박 = clearly, carefully, one character at a time
• 분명하게 = clearly, distinctly

In this sentence, 정확하게 suggests that the information should be written without error. That makes sense on an application form.

신청서 means application form.

It is made up of:

• 신청 = application, request
• 서 = document, form

So 신청서 is the document you fill out when applying for something.

It is a fairly common and practical word, especially in offices, schools, government settings, memberships, registrations, and similar situations.

It is in the polite informal style, using -아요/어요:

• 써요

This level is polite and common in everyday Korean. It is appropriate for:

• speaking politely
• simple instructions
• customer service situations
• spoken guidance

However, in a very formal written notice, you might see a different style, such as:

• 먼저 이 신청서에 이름을 정확하게 쓰십시오.
• 먼저 이 신청서에 이름을 정확하게 작성해 주십시오.

So the original sentence is polite, natural, and everyday in tone.
