yòng mǎkèbǐ xiě biāoqiān.

用 introduces the tool or means used to do something, so here it means using or with.

The pattern is:

用 + tool + verb + object

So:

• 用马克笔写标签 = use a marker to write labels

This is a very common Chinese structure. English often puts with later in the sentence, but Chinese often puts the tool near the beginning.

Examples:

• 用筷子吃饭 = eat with chopsticks
• 用手机拍照 = take photos with a phone

Chinese often omits the subject when it is obvious from context.

In 用马克笔写标签, the sentence sounds like:

• an instruction
• a reminder
• a label on a worksheet
• a step in directions

So the subject is understood, something like:

• 你用马克笔写标签
• 请用马克笔写标签

But Chinese commonly leaves that unstated.

Yes, very likely.

Without a subject, this sentence naturally reads like an instruction:

• Use a marker to write the labels
• Write the labels with a marker

Chinese often gives instructions in a plain verb phrase like this. If you want to make it sound more polite, you can add 请:

• 请用马克笔写标签。

If you want to make it a suggestion, you might add 吧:

• 用马克笔写标签吧。

马克笔 means marker pen or marker. It is a common everyday word.

It is basically a loanword based on mark plus 笔.

You may also hear:

• 记号笔 = marker pen
• 油性马克笔 = permanent marker
• 白板笔 = whiteboard marker

In many situations, 马克笔 and 记号笔 are very close in meaning.

Both are possible, but they focus a little differently.

写标签

This treats 标签 as the object of 写. It means something like:

• write labels
• fill out labels
• make the labels by writing on them

在标签上写

This emphasizes the surface you write on:

• write on the label

Example:

• 在标签上写名字。 = Write the name on the label.

So 写标签 is a natural, compact way to say this in an instruction.

Usually, not naturally in this sentence.

• 用马克笔写标签 = natural
• 马克笔写标签 = not natural as a normal sentence

Chinese normally needs 用 to show that 马克笔 is the instrument.

You could use a different verb, such as:

• 拿马克笔写标签 = take a marker and write labels

But 用 is the most straightforward choice here.

Because Chinese normally uses verb + object order.

So:

• 写标签 = write labels
• 吃饭 = eat food / eat a meal
• 看书 = read a book

Putting 标签 before 写 would not work as the normal object placement here.

No, not in this sentence.

Measure words are needed when you specify a number:

• 一支马克笔 = one marker
• 两支马克笔 = two markers

But in 用马克笔写标签, the sentence is speaking generally, so no measure word is needed.

If you wanted to be more specific, you could say:

• 用一支马克笔写标签。

That would mean use one marker to write the labels, though it sounds a little more specific than the original.

标签 means label or tag.

In Chinese, nouns usually do not have a built-in singular/plural form like English nouns do. So 标签 can mean:

• label
• labels

The exact number depends on context.

If you want to make it clearly singular or plural, you can add a number:

• 一个标签 = one label
• 两个标签 = two labels

No.

• 写标签 = write the label / write on the label
• 贴标签 = stick on a label / attach a label

So:

• If you are writing words on labels, use 写标签
• If you are physically putting labels onto something, use 贴标签

You might even do both:

• 先写标签，再贴标签。 = First write the labels, then stick them on.

It is natural, especially in written instructions, classroom directions, craft activities, office tasks, or labeling items.

It is short and efficient, which is very common in Chinese instructions.

For spoken everyday Chinese, people might also say:

• 请用马克笔写标签。
• 用马克笔把标签写一下。
• 拿马克笔写标签。

But the original sentence is perfectly normal.

The pinyin given is:

• 用 = yòng
• 马克笔 = mǎ kè bǐ
• 写 = xiě
• 标签 = biāo qiān

A few notes:

• 马 mǎ is third tone
• 克 kè is fourth tone
• 笔 bǐ is third tone
• 写 xiě is third tone
• 标 biāo is first tone
• 签 qiān is first tone

In natural speech, third tones are often not pronounced as full dipping tones every time, especially before other tones, so don’t be surprised if they sound a bit lighter in real speech.

Yes, you can, but 来 is optional.

• 用马克笔写标签
• 用马克笔来写标签

Both are grammatical. Adding 来 can make the sentence feel slightly more deliberate, but in many everyday cases it is unnecessary.

The shorter version is more direct and common in instructions.

Yes, but it changes the structure.

For example:

• 用马克笔把标签写好。

This means something like:

• use a marker to write the labels properly / finish writing the labels

With 把, the object 标签 is placed before the verb phrase, and the sentence often emphasizes the handling or completion of the object.

But for the basic instruction, 用马克笔写标签 is simpler and more neutral.

No, it would just make the instruction more polite.

Compare:

• 用马克笔写标签。 = Use a marker to write the labels.
• 请用马克笔写标签。 = Please use a marker to write the labels.

So 请 is optional and affects tone, not the core grammar.
