Cậu trộn nguyên liệu nhé.

In this sentence, cậu means you.

It is a personal pronoun used in an informal, familiar way, often between:

• friends
• classmates
• people of similar age
• someone speaking casually to a younger person in some contexts

So Cậu trộn nguyên liệu nhé. is addressing you directly, but in a friendly, not overly formal way.

No. Vietnamese pronouns depend a lot on the relationship between speakers.

Cậu is natural when:

• talking to a friend
• talking to someone close in age
• speaking casually

But it may sound odd or inappropriate if you use it:

• with strangers
• with older people
• in formal situations
• with someone who should be addressed more respectfully

Vietnamese chooses pronouns based on age, status, closeness, and family-style social roles. So cậu is not a universal word for you.

Trộn means to mix.

It is commonly used when combining ingredients, substances, or things together, for example:

• trộn bột = mix flour
• trộn salad = mix a salad
• trộn nguyên liệu = mix the ingredients

In this sentence, it means physically combining the ingredients together.

Nguyên liệu means ingredients or materials, depending on context.

In cooking, it usually means ingredients.

Vietnamese nouns usually do not have different singular and plural forms the way English does. So nguyên liệu can mean:

• ingredient
• ingredients

The context tells you which one is meant. In a cooking sentence like this, English will usually translate it as the ingredients or ingredients.

Vietnamese does not use articles like English the, a, or some in the same way.

So nguyên liệu can naturally stand on its own without any extra word before it.

Depending on context, it could be understood in English as:

• the ingredients
• some ingredients
• just ingredients

English needs an article or determiner more often than Vietnamese does, but Vietnamese often leaves that information unstated unless it matters.

Nhé is a sentence-final particle that softens the tone.

Here it makes the sentence sound:

• gentler
• friendlier
• less blunt
• more like a suggestion or polite request

Without nhé, Cậu trộn nguyên liệu. can sound more direct, like a plain instruction. With nhé, it feels more like:

• Please mix the ingredients, okay?
• You mix the ingredients, alright?

It does not change the core action, but it changes the speaker’s attitude.

It is most naturally a gentle instruction or friendly request.

Because of nhé, it usually does not sound like a harsh command. It feels more cooperative and soft.

So depending on context, it could be understood as:

• a mild command
• a request
• a suggestion in a teamwork situation

The exact force depends on tone of voice and situation.

The basic order is:

Cậu + trộn + nguyên liệu + nhé
subject + verb + object + sentence-final particle

So:

• Cậu = you
• trộn = mix
• nguyên liệu = ingredients
• nhé = softening particle

This is a very common Vietnamese pattern.

Yes, often you can.

Vietnamese frequently omits pronouns when the subject is already clear from context. So in real conversation, someone might simply say:

Trộn nguyên liệu nhé.

That still means something like:

• Mix the ingredients, okay.
• Please mix the ingredients.

Including cậu makes the addressee explicit and can add a slightly more personal or contrastive feel.

No tense is marked directly here.

Vietnamese verbs do not change form the way English verbs do. Trộn stays the same whether the action is happening now, later, or in a general instruction.

In this sentence, the context makes it sound like a present or immediate future instruction, such as:

• Mix the ingredients now
• You can mix the ingredients next

If needed, Vietnamese can add time words like:

• bây giờ = now
• sau đó = after that
• ngày mai = tomorrow

But this sentence does not need one.

Without nhé, the sentence becomes:

Cậu trộn nguyên liệu.

This is still grammatical, but it sounds more direct and matter-of-fact. Depending on tone, it could feel:

• more like an instruction
• more neutral
• less warm

Adding nhé makes it friendlier and more natural in many everyday situations, especially when giving small instructions politely.

Both can relate to materials, but they are used differently.

• nguyên liệu usually means ingredients or raw materials, especially things used to make something
• vật liệu usually means materials in a more general or technical sense, such as building materials

So in cooking, nguyên liệu is the normal choice:

• nguyên liệu nấu ăn = cooking ingredients

Using vật liệu here would sound wrong.

A rough pronunciation guide is:

Cậu trộn nguyên liệu nhé
≈ gow tron ngwee-en lee-uh nyeh

A few important notes:

• cậu has a falling, heavy tone
• trộn also has a heavy tone and starts with tr
• nguyên begins with the ng sound, like the end of English sing
• liệu has a gliding vowel sound
• nhé starts with nh, a sound similar to the ny in canyon for many learners

The tones are important, so it is best to hear a native recording if possible.

Yes, but the nuance changes.

For example:

• Cậu trộn nguyên liệu đi. = more like Go ahead and mix the ingredients
• Cậu trộn nguyên liệu nha. = very similar to nhé, often a more casual spelling/pronunciation in informal speech
• Cậu trộn nguyên liệu nhé. = soft, friendly, common

So nhé is a good natural choice when you want to sound polite and gentle without being formal.
