Tên của tôi là An.

Word by word:

• Tên = name
• của = a possession marker, like of or sometimes English ’s
• tôi = I / me / my
• là = am / is / are in an equational sentence
• An = the name

So the structure is literally something like Name of me is An.

Của shows possession.

• tên của tôi = my name
• literally: name of me

It works a lot like of in English, and sometimes like the English possessive ’s.

That said, Vietnamese often drops của when the meaning is already clear:

• Tên tôi là An is also very natural.

So của is correct, but not always required in simple everyday speech.

It is natural and fully correct, but many speakers would also say:

• Tên tôi là An.

This is slightly shorter and very common.

So:

• Tên của tôi là An. = correct, clear, a bit fuller
• Tên tôi là An. = also correct, very common

Both mean the same thing.

Là links two things together, like the verb to be in sentences such as:

• Tôi là An. = I am An.
• Đây là bạn tôi. = This is my friend.

In Tên của tôi là An, là connects my name with An.

So yes, here là works like is.

In this kind of sentence, usually no.

You normally keep là when you are identifying or equating one thing with another:

• Tên tôi là An.
• Tôi là sinh viên.
• Đây là nhà tôi.

Vietnamese sometimes omits a verb equivalent to to be with adjectives, for example:

• Tôi mệt. = I am tired.

But with noun-to-noun identification like My name is An, là is normally used.

Vietnamese often follows a straightforward topic + description pattern.

Here:

• Tên của tôi = the topic: my name
• là An = what it is: is An

So the sentence is built as:

• [My name] [is An]

That is actually very close to English word order in My name is An.

Yes. Tôi là An means I am An, and it is very common when introducing yourself.

The difference is small:

• Tôi là An. = I’m An.
• Tên tôi là An. = My name is An.

Both are natural.
Tôi là An is usually more direct and more common in real conversation.

Tôi is a common, neutral way to say I in Vietnamese. It is polite and safe in many situations.

However, Vietnamese pronouns depend a lot on age, relationship, and social context. In real life, speakers often use other words instead of tôi, such as:

• mình
• em
• anh
• chị
• con
• cháu

So tôi is a good standard learner word, but it is not the only way to say I.

Here, An is usually understood as the person’s given name.

In Vietnamese, the usual name order is:

• family name
• middle name
• given name

For example:

• Nguyễn Hoàng An

In casual introduction, people often use just the given name, so saying Tôi là An or Tên tôi là An is completely normal.

A rough guide:

• Tên: sounds somewhat like tane, but with a rising tone
• của: roughly koo-uh or gwuh, depending on accent
• tôi: roughly toy
• là: roughly lah, with a low/falling tone
• An: roughly like ahn

A very rough full approximation might be:

• Tane koo-uh toy lah ahn

But the tones matter a lot in Vietnamese, so English-style pronunciation will only be approximate.

The tones are:

• Tên — sắc tone
• của — hỏi tone on củ
• tôi — ngang tone
• là — huyền tone
• An — ngang tone

For learners, it is helpful to notice that written tone marks are part of the word, not optional accents.

Yes, in some situations.

• Tên mình là An can sound more casual, friendly, or softer.
• Tên tôi là An sounds more neutral and standard.

However, mình depends more on context and relationship, so tôi is usually the safer choice for beginners.

It is mostly neutral.

• Tên của tôi là An. sounds correct, clear, and slightly careful.
• Tên tôi là An. is a bit more natural in everyday speech.
• Tôi là An. is often the simplest and most conversational.

So the sentence is not overly formal, but it is a little fuller than what people often say in casual conversation.

Yes.

• An is a proper name, so it is capitalized.
• The period is standard if you are writing a complete sentence.

So the normal written form is:

• Tên của tôi là An.
