Trò này khiến bé khóc.

In Vietnamese, demonstratives like này (this) usually come after the noun.

So:

• trò này = this game / this trick
• not này trò

This is a very common pattern:

• nhà này = this house
• người này = this person
• con mèo này = this cat

So the noun comes first, and the word meaning this/that comes after it.

Trò can have a few related meanings depending on context, such as:

• game
• trick
• prank
• act / stunt

So trò này could mean something like:

• this game
• this trick
• this prank

The exact English choice depends on the situation. Vietnamese often allows this kind of flexibility, and context tells you which meaning is intended.

Khiến means to cause, to make, or to lead someone to do something / be in a state.

In this sentence, it links the cause to the result:

• Trò này = the thing causing the effect
• khiến = makes / causes
• bé = the person affected
• khóc = cry

So the pattern is:

X khiến Y + verb

= X makes Y do something

Examples:

• Tin đó khiến tôi buồn. = That news made me sad.
• Câu nói ấy khiến cô ấy cười. = That remark made her laugh.

Vietnamese does not need an extra word like English to in this kind of structure.

In English, we say:

• This makes the child cry.

In Vietnamese, the equivalent structure is simply:

• khiến bé khóc

So after khiến, Vietnamese can go straight to:

• the affected person/object
• then the verb or state

There is no need for a separate marker like to.

Bé often refers to a small child, not necessarily a literal baby.

Depending on context, it can mean:

• little child
• kid
• toddler
• baby

It is also commonly used as a familiar way to refer to a young child.

So in this sentence, bé is best understood as the child / the little one, unless the context specifically shows it is a baby.

Vietnamese does not use articles the way English does.

English often requires:

• a child
• the child

Vietnamese usually does not have separate words that match a and the exactly. Whether bé means a child, the child, or just the little one depends on context.

So bé by itself is perfectly normal.

They are similar, but not always identical in tone.

In this sentence, khiến and làm can often both be translated as make:

• Trò này khiến bé khóc.
• Trò này làm bé khóc.

The difference is mainly style:

• khiến can sound a bit more formal, written, or literary
• làm is often more common in everyday speech

So many learners will hear làm more often in conversation, but khiến is still very useful and natural.

The structure is:

Subject + khiến + object + verb

For this sentence:

• Trò này = subject / cause
• khiến = makes
• bé = object / affected person
• khóc = verb

So literally, it is something like:

This game/trick makes the child cry.

That word order is very typical for causative sentences in Vietnamese.

Yes. Vietnamese verbs do not change form the way English verbs do.

khóc can correspond to:

• cry
• cries
• crying
• cried

The exact time and aspect come from context or from extra words, not from changing the verb itself.

For example:

• bé khóc = the child cries / is crying
• bé đã khóc = the child cried / has cried
• bé đang khóc = the child is crying

So in your sentence, khóc stays in its basic form.

Vietnamese often leaves tense unmarked if the time is already clear from context.

So Trò này khiến bé khóc could mean different things depending on the situation, such as:

• this makes the child cry
• this is making the child cry
• this made the child cry

If the speaker wants to be more explicit, they can add time/aspect words such as:

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

Examples:

• Trò này đã khiến bé khóc. = This made the child cry.
• Trò này đang khiến bé khóc. = This is making the child cry.

Yes, it is grammatical and natural, especially in writing or careful speech.

A learner should just know that:

• khiến sounds slightly more formal than làm
• in everyday conversation, people might more often say Trò này làm bé khóc

So the sentence is good Vietnamese; it just has a somewhat more polished tone than the most casual spoken version.
