Nhân viên chăm sóc động vật cho nó ăn.

The sentence is:

• Nhân viên chăm sóc động vật = the subject
• cho nó ăn = the verb phrase / predicate

So the overall structure is basically:

[subject] + [action]

A very literal breakdown is:

• nhân viên = employee/staff member
• chăm sóc động vật = takes care of animals / animal care
• cho nó ăn = feeds it

Vietnamese often keeps a straightforward subject–verb–object style, but noun phrases can contain extra descriptive material inside them.

Because Vietnamese often does not need a relative pronoun like English does.

In English, you might say:

• the employee who takes care of animals

In Vietnamese, you can simply put the descriptive verb phrase after the noun:

• nhân viên chăm sóc động vật

This literally looks like:

• employee + care for animals

But it naturally means:

• the employee who cares for animals
• or animal-care employee

So the idea of who/that is understood from the structure.

Not here.

In this sentence, chăm sóc động vật is part of the subject noun phrase:

• nhân viên chăm sóc động vật = animal-care employee / employee who cares for animals

The main action of the whole sentence is:

• cho nó ăn = feeds it

So:

• chăm sóc động vật describes what kind of employee
• cho nó ăn tells you what that employee is doing

This is a very common Vietnamese pattern.

• cho often means give
• ăn means eat

But cho + someone/something + ăn means:

• to feed someone/something
• literally, to give someone/something something to eat

So:

• cho nó ăn = feed it
• more literally = give it food / give it something to eat

This is normal and idiomatic Vietnamese.

Because ăn by itself means eat, not feed.

Compare:

• Nó ăn. = It eats.
• Nhân viên cho nó ăn. = The employee feeds it.

So if the employee is doing the action to the animal, Vietnamese uses the pattern cho + object + ăn.

Here, nó refers to the animal being fed.

Yes, nó is very normal for animals and objects. It often means:

• it
• sometimes he/she in certain contexts, but that depends on relationship and tone

For animals, nó is usually fine.

Important note:

• Using nó for an adult person can sound rude, distant, or dismissive unless the context makes it natural.
• For animals, it is usually not a problem.

Vietnamese does not work like English in this area.

Nouns usually do not change form for:

• singular/plural
• a/an/the

So:

• nhân viên can mean an employee, the employee, or employees
• động vật can mean animal or animals

The exact meaning depends on context.

In this sentence, English will usually choose the most natural interpretation from the situation, but Vietnamese itself does not have to mark those things explicitly.

Because động vật here is being used in a general, non-counting way.

Classifiers are common in Vietnamese when you are counting or pointing to specific nouns, for example:

• một con chó = a dog
• con mèo đó = that cat

But in chăm sóc động vật, the noun động vật is generic and part of a descriptive phrase:

• care for animals
• animal care

So no classifier is needed here.

You usually do not know from the verb form alone, because Vietnamese verbs do not change like English verbs do.

So cho nó ăn could mean different things depending on context:

• feeds it
• is feeding it
• fed it
• will feed it

If the speaker wants to make time clearer, they can add time words or markers such as:

• đang = ongoing, is ...ing
• đã = past/completed
• sẽ = future

For example:

• Nhân viên chăm sóc động vật đang cho nó ăn. = The animal-care employee is feeding it.
• ... đã cho nó ăn. = ... fed it / has fed it.
• ... sẽ cho nó ăn. = ... will feed it.

Yes, absolutely.

Depending on context, natural English translations could include:

• animal-care employee
• animal caretaker
• animal care worker
• zoo staff member or pet-care staff member if the context makes that clear

The Vietnamese phrase itself is fairly flexible. It identifies a staff member whose job involves caring for animals.

Yes, definitely.

cho ăn is a very useful everyday pattern meaning:

• feed

You can use it with many objects:

• cho chó ăn = feed the dog
• cho mèo ăn = feed the cat
• cho em bé ăn = feed the baby

It is worth learning as a chunk, because it is much more natural than trying to translate feed word-for-word from English.
