Vidim srećno dete.

• Vidim = I see
• srećno = happy
• dete = child

So the sentence means I see a happy child.

In Serbian, the verb ending often already shows who is doing the action, so the subject pronoun is often left out.

• vidim = I see
• the ending -im tells you it is first person singular: I

You can say Ja vidim srećno dete, but ja is usually unnecessary unless you want emphasis, contrast, or clarity.

Because dete is a neuter noun, and the adjective has to agree with it in gender, number, and case.

The adjective srećan changes like this in the singular:

• srećan = masculine
• srećna = feminine
• srećno = neuter

Since dete is neuter singular, the correct form is srećno dete.

In Serbian, grammatical gender does not always match natural gender.

So even though a child is a person, the noun dete is grammatically neuter. That means adjectives and some other words must use neuter forms with it:

• malo dete = a small child
• srećno dete = a happy child

This is something you simply have to learn with the noun.

Serbian does not have articles like English a/an and the.

So dete can mean:

• a child
• the child

Which one is meant depends on context.

That means Vidim srećno dete could be understood as:

• I see a happy child
• I see the happy child

Usually the situation tells you which meaning is intended.

Yes, the direct object after videti is normally in the accusative case. Here, dete is indeed the object.

The important point is that for some neuter nouns, the nominative and accusative singular have the same form.

So:

• nominative: dete = child
• accusative: dete = child

The case is still accusative in the sentence, but it just happens to look the same.

Yes. The adjective must match the noun it describes in gender, number, and case.

Since dete is:

• neuter
• singular
• accusative

the adjective must also be:

• neuter
• singular
• accusative

And for this pattern, the form is srećno.

So srećno dete is a matching adjective + noun phrase.

Yes, Serbian word order is more flexible than English because case endings help show the grammatical roles.

The most neutral word order here is:

• Vidim srećno dete.

But other orders are possible, such as:

• Srećno dete vidim.
• Dete vidim srećno. (less neutral, and can sound stylistically marked or ambiguous depending on context)

Changing word order often changes emphasis, not the basic meaning.
For a learner, Vidim srećno dete is the safest and most natural neutral order.

A rough pronunciation is:

• srećno ≈ SRECH-no

More precisely:

• ć is a soft sound, somewhat like a very soft ch sound
• the stress is typically on the first syllable: SRE-ćno

And the whole sentence is roughly:

• Vidim srećno dete
• VEE-deem SRECH-no DEH-te

These are only approximations using English spelling.

This is a very common question.

• vidim = I see
• gledam = I look at / I am watching

So:

• Vidim srećno dete = I see a happy child
• Gledam srećno dete = I am looking at / watching a happy child

Videti is about perception: you see something.
Gledati is about directing your eyes toward something.

The dictionary form is videti or sometimes vid(j)eti depending on the grammar tradition and variety.

• videti = to see
• vidim = I see

So vidim is the 1st person singular present tense form of videti.

Usually dete means child. In some contexts it can refer to a very young child, but it is not exactly the same as English baby.

More specific words include:

• beba = baby
• dete = child

So in most cases, srećno dete is best understood as happy child, not specifically happy baby.

You would need plural forms:

• Vidim srećnu decu. = I see happy children.

Changes:

• dete becomes decu in the accusative plural
• the adjective changes too: srećnu

This is a good example of how Serbian changes both the noun and the adjective to match number and case.

Yes, srećno can also be an adverb in other contexts, meaning something like happily or in some expressions good luck / safely.

But in Vidim srećno dete, it is not an adverb. Here it is an adjective describing dete.

You can tell because it agrees with the noun:

• srećno dete = happy child

So in this sentence, srećno means happy, not happily.
