Động vật hoang dã có bản năng hoang dã.

Because it describes two different nouns:

• động vật hoang dã = wild animals
• bản năng hoang dã = wild instinct(s)

Vietnamese often repeats an adjective if it applies to two separate noun phrases. So this is grammatically normal. It may sound a little repetitive stylistically, but it is still clear and correct.

It is written as two syllables, hoang dã, but it functions as one adjective phrase meaning wild, untamed, or in the wild.

In Vietnamese, many words are made of two written syllables, especially Sino-Vietnamese vocabulary. So even though there is a space, learners should think of hoang dã as one vocabulary item.

Because Vietnamese usually puts descriptive adjectives after the noun.

So:

• động vật hoang dã literally follows the pattern animal wild
• bản năng hoang dã literally follows the pattern instinct wild

This is one of the biggest word-order differences from English.

Có means to have in this sentence.

So the basic structure is:

• Động vật hoang dã = subject
• có = have
• bản năng hoang dã = object

A very literal breakdown is:

• Động vật hoang dã = wild animals
• có = have
• bản năng hoang dã = wild instinct

It can be either singular or plural depending on context, because Vietnamese nouns usually do not change form for number.

In this sentence, động vật hoang dã is understood generically, like wild animals as a class. Vietnamese often leaves singular/plural unspecified unless it needs to be precise.

Vietnamese does not use articles the way English does.

So a noun like động vật can mean:

• animal
• an animal
• the animal
• animals

Context tells you which one is intended. In this sentence, it is a general statement, so English naturally uses wild animals.

Động vật means animal or animals.

It is a formal/common compound:

• động = moving
• vật = thing, creature, object

So historically it is something like moving creature. In modern Vietnamese, you should just learn động vật as the normal word for animal.

Bản năng means instinct.

It is a noun, not an adjective. So in this sentence:

• bản năng hoang dã = wild instinct

You can think of bản năng as an internal natural drive or instinctive behavior.

It sounds like a general truth.

Vietnamese verbs do not change form for tense the way English verbs do. There is no special ending on có. A sentence like this is understood from context as a general fact:

• Wild animals have wild instincts.

If you wanted to mark time more clearly, Vietnamese would add time words or aspect markers, but none are needed here.

A rough guide:

• hoang: sounds somewhat like hwang or ho-ahng, said as one syllable
• dã: in Northern Vietnamese, d sounds like a z sound, so roughly zah with the ngã tone

A few useful pronunciation notes:

• dã has the ngã tone, which can be tricky for learners.
• In Southern speech, the ngã and hỏi tones are often merged, so dã may sound different from Northern pronunciation.
• The d in standard Northern Vietnamese is not like English d.

A rough full pronunciation might be something like:

• động vật hoang dã có bản năng hoang dã
• roughly: dohng vuht hwang zah koh bahn nung hwang zah

That is only approximate, but it can help you get started.

They are different letters in Vietnamese.

• đ in động is pronounced like an English d
• d in dã is pronounced like z in Northern Vietnamese, and more like y in many Southern accents

So:

• động starts with a real d sound
• dã does not

This difference is very important in Vietnamese spelling and pronunciation.

Yes. Động vật hoang dã is a very common phrase meaning wild animals or wildlife, depending on context.

For example:

• bảo vệ động vật hoang dã = protect wild animals / protect wildlife
• săn bắt động vật hoang dã = hunt wild animals

So this is a useful chunk to memorize as a set phrase.

Yes. Vietnamese adjectives can often act like predicates without needing a word like to be.

For example:

• Con vật này hoang dã. = This animal is wild.

But in your sentence, hoang dã is used attributively, meaning it directly modifies the nouns:

• động vật hoang dã
• bản năng hoang dã

So Vietnamese lets the same adjective work in more than one way.
