Vaksin ini untuk anjing.

• vaksin = vaccine
• ini = this
• untuk = for
• anjing = dog / dogs

So the sentence structure is literally vaccine this for dog(s), which naturally means This vaccine is for dogs.

In Malay, the verb to be is often left out in simple sentences like this.

So:

• Vaksin ini untuk anjing = This vaccine is for dogs

Malay does not need a separate word for is here. This is very common. English requires is, but Malay often does not.

In Malay, demonstratives like ini (this) and itu (that) usually come after the noun.

So:

• vaksin ini = this vaccine
• anjing itu = that dog

This is different from English, where this comes before the noun.

It can mean either, depending on context.

Malay nouns usually do not change form for singular or plural. So anjing can mean:

• dog
• dogs

In this sentence, the natural English translation is usually dogs, because This vaccine is for dogs sounds more normal in context.

If Malay speakers want to make the plural very explicit, they can sometimes use reduplication:

• anjing-anjing = dogs

But in many everyday sentences, the simple form anjing is enough.

Malay does not normally use articles like English does.

So vaksin can mean:

• a vaccine
• the vaccine
• just vaccine

The exact meaning depends on context. In vaksin ini, the word ini already makes it specific, so it means this vaccine.

Untuk usually means for, and that is exactly how it works here:

• untuk anjing = for dogs

It is commonly used for purpose, recipient, or intended use.

Examples:

• Hadiah untuk Ali = a gift for Ali
• Ubat untuk demam = medicine for fever
• Makanan untuk kucing = food for cats

So in this sentence, untuk shows who the vaccine is intended for.

Yes, you could, but it is usually less natural in everyday speech.

• Vaksin ini untuk anjing = more natural, simple, common
• Vaksin ini adalah untuk anjing = grammatical, but more formal or emphatic

The word adalah is sometimes used in more formal writing, definitions, or presentations, but in ordinary conversation it is often omitted.

A rough guide:

• anjing ≈ ahn-jeeng

Notes:

• a sounds like the a in father
• nj is similar to the sound in canyon or the nj in some pronunciations of banjo, depending on accent
• i sounds like ee
• ng is the normal ng sound as in sing

So the whole word is roughly ahn-jeeng.

A rough pronunciation is:

VAK-seen EE-nee oon-TOOK AHN-jeeng

Word by word:

• vaksin = VAK-seen
• ini = EE-nee
• untuk = oon-TOOK
• anjing = AHN-jeeng

Malay pronunciation is generally quite regular, much more regular than English spelling.

Yes, it can, depending on context.

Because Malay nouns do not usually mark singular/plural the way English does, anjing can refer to:

• a dog
• the dog
• dogs

If the situation is about one specific dog, a speaker might understand it as This vaccine is for a dog or for the dog. If it is talking about animal use in general, for dogs is the most natural translation.

You would replace ini (this) with itu (that):

• Vaksin itu untuk anjing. = That vaccine is for dogs.

This shows the same Malay pattern:

• noun + ini = this noun
• noun + itu = that noun
