Tớ nấu cơm; cậu cắt hành.

They are informal second- and first-person pronouns used between equals, especially friends or people of similar age.

• tớ = I / me
• cậu = you

This pair sounds casual, friendly, and familiar. It is common among younger speakers, classmates, close friends, and sometimes couples.

It is not the most neutral pair for every situation. For example:

• with strangers, people often use other pronouns
• with older people, tớ/cậu may sound inappropriate
• in formal situations, tôi is more common for I

So in this sentence, the tone is basically: We’re close enough that I can say, “I’ll cook the rice; you chop the onions.”

No. tớ and cậu are not inherently male or female.

Either a man or a woman can use them, depending on the relationship and situation. What matters more is the social relationship and level of familiarity, not gender.

Vietnamese often does not require a verb like "to be" in places where English does, and it also often does not mark tense unless needed.

In this sentence:

• Tớ nấu cơm = I cook / I’m cooking / I’ll cook the rice
• cậu cắt hành = you cut / you’re cutting / you’ll chop the onions

The exact time is understood from context. Here, the sentence most naturally sounds like a plan or division of tasks, so English may translate it as:

• I’ll cook the rice; you chop the onions.
• I cook the rice; you chop the onions.
• I’m cooking the rice; you cut the onions.

Vietnamese leaves that flexible unless a time marker is added, such as:

• đang = ongoing action
• sẽ = future
• đã = past

Most basically, nấu cơm means cook rice.

That is the most direct reading:

• nấu = cook
• cơm = cooked rice / rice as food

In Vietnamese, cơm is a very important everyday word and can sometimes extend to meanings connected with a meal, especially a meal centered around rice. But in this sentence, the most natural interpretation is simply:

• cook the rice

So if two people are preparing food together, Tớ nấu cơm; cậu cắt hành strongly suggests: I’ll cook the rice; you chop the onions.

Hành usually refers to the onion/scallion family, and the exact English translation depends on context.

It can mean things like:

• onion
• scallion / green onion
• shallot, in some contexts

So cắt hành means cut/chop the onions/scallions/shallots.

In natural English, translators often choose chop the onions because that sounds smooth and general, but the Vietnamese word is a bit broader than just one exact English vegetable word.

Because Vietnamese is commonly Subject–Verb–Object (SVO), just like basic English word order.

So:

• Tớ = subject
• nấu = verb
• cơm = object

and

• cậu = subject
• cắt = verb
• hành = object

That makes this sentence structurally easy for English speakers:

• Tớ nấu cơm → I cook rice
• cậu cắt hành → you cut onions

Of course, Vietnamese has its own grammar rules, but this basic sentence pattern is very familiar to English speakers.

The semicolon links two closely related clauses:

• Tớ nấu cơm
• cậu cắt hành

It shows that these are two separate actions, but they belong together as part of the same situation or plan.

In English, a semicolon works similarly:

• I’ll cook the rice; you chop the onions.

In Vietnamese writing, people might also use:

• a comma: Tớ nấu cơm, cậu cắt hành.
• a period: Tớ nấu cơm. Cậu cắt hành.

The semicolon just gives a neat sense of division of tasks.

It can feel like a plan or a task assignment, depending on tone and context.

Literally, it is just two plain clauses:

• I cook rice
• you chop onions

But in real use, it often implies something like:

• I’ll cook the rice, and you chop the onions.
• I’m taking care of the rice; you take care of the onions.

So even without a special command form, Vietnamese can use simple statements to express a practical arrangement.

Yes, grammatically you could, but the tone would change.

For example:

• Tôi nấu cơm; bạn cắt hành.

This sounds more neutral and less intimate than tớ/cậu.

Very roughly:

• tớ / cậu = casual, friendly, familiar
• tôi / bạn = more neutral, sometimes more distant or polite

So the original sentence is not just about meaning; it also tells you something about the relationship between the speakers.

Vietnamese does not use articles the same way English does.

So:

• cơm can mean rice / the rice
• hành can mean onion(s) / the onion(s)

The listener understands the intended meaning from context.

In a cooking situation, cắt hành naturally means something like:

• cut the onions
• chop some onion

English forces you to choose more specifically; Vietnamese often does not.

Because Vietnamese nouns often do not have to show singular vs. plural explicitly.

So hành could mean:

• onion
• onions
• some onion/scallions

If the speaker wants to be more specific, Vietnamese can add words for quantity or number, but it is not necessary here.

That is why cắt hành is perfectly normal even though English usually prefers chop the onions or chop some onions.

Yes. Cắt is a general word meaning cut.

Depending on context, it may be translated as:

• cut
• chop
• slice

So cắt hành literally means cut onion/onions, but in natural cooking English, chop the onions is often the best translation.

If Vietnamese wants to be more specific about the style of cutting, it can use more specific wording, but cắt alone is very common.

The tone marks matter a lot in Vietnamese. A rough guide:

• tớ — has the sắc tone: rising
• nấu — has the ngã tone: often described as a broken/rising tone, depending on dialect
• cậu — has the nặng tone: low, short, heavy/glottalized
• cắt — also sắc tone on ắ: rising, short
• hành — huyền tone: low/falling

A rough northern-style approximation:

• tớ
• nấu
• cậu
• cắt
• hành

But exact pronunciation varies by region, especially with tones like ngã. For a learner, the most important point is:

• don’t ignore the marks
• they are part of the word, not optional accents

In some contexts, yes, but this sentence is clearer with them included.

Vietnamese sometimes drops subjects when they are obvious from context. But here, since the speaker is assigning different tasks to two different people, keeping both pronouns makes the division clear:

• Tớ nấu cơm
• cậu cắt hành

If you removed them, it could become less clear who is doing what.

So in this sentence, the pronouns are doing important work.

Yes, in meaning, there is a coordination idea like and / while / as for your part.

Vietnamese does not need to insert a separate word here. The punctuation and context already connect the two actions.

So the sentence feels like:

• I’ll cook the rice, and you chop the onions.
• I cook the rice; you cut the onions.

Sometimes Vietnamese does use linking words in similar sentences, but here the semicolon is enough.
