Ovo pakovanje je dovoljno.

Because pakovanje is a neuter noun, and ovo is the neuter singular form of this.

Serbian demonstratives must agree with the noun in gender, number, and case:

• ovaj = masculine singular
• ova = feminine singular
• ovo = neuter singular

So:

• ovaj paket = this package/parcel
• ova kutija = this box
• ovo pakovanje = this pack/package

Pakovanje is neuter.

A very common clue is the ending -e or -o in the dictionary form of a noun, though you still need to learn nouns individually. In this case, pakovanje is a neuter noun, and many nouns ending in -nje are neuter.

That is why both ovo and dovoljno appear in neuter form too.

Pakovanje can mean things like:

• package
• pack
• packaging
• a packaged unit

The exact meaning depends on context. In everyday use, it often refers to a pack/unit of goods, such as a pack of coffee, medicine, or food. So learners should not assume it always means only packaging material.

Je is the 3rd person singular present tense of biti (to be), meaning is.

So the sentence structure is:

• Ovo pakovanje = subject
• je = is
• dovoljno = enough / sufficient

Serbian usually uses the present tense of to be in this kind of sentence, just as English does:

• Ovo pakovanje je dovoljno. = This package is enough.

Normally, in standard Serbian, no.

You usually need je in a sentence like this. Leaving it out would sound incomplete or nonstandard in ordinary speech.

So:

• Ovo pakovanje je dovoljno. ✅
• Ovo pakovanje dovoljno. ❌ in normal standard Serbian

Because here it agrees with the neuter noun pakovanje.

The adjective is based on dovoljan = sufficient / enough. Its forms are:

• dovoljan = masculine
• dovoljna = feminine
• dovoljno = neuter

So compare:

• Ovaj paket je dovoljan. = This package is enough.
• Ova kutija je dovoljna. = This box is enough.
• Ovo pakovanje je dovoljno. = This pack is enough.

Here it is best understood as an adjective used predicatively.

It describes the subject pakovanje, so it agrees with it in gender and number. That is why it appears in the neuter singular form dovoljno.

Learners get confused because dovoljno can also be an adverb in other sentences, for example:

• Radi dovoljno brzo. = He/she works sufficiently fast.

But in Ovo pakovanje je dovoljno, it is connected to the noun through je, so it is functioning as a predicate adjective.

It is in the nominative singular.

Why?

• Ovo pakovanje is the subject of the sentence.
• Subjects are normally in the nominative case.

Also, the demonstrative ovo is nominative singular neuter here, matching pakovanje.

Because Serbian has no articles.

Unlike English, Serbian does not have separate words for a/an and the. Whether something is definite or indefinite is understood from context, word order, or added words like demonstratives.

So:

• pakovanje can mean a package, the package, or just package/packaging, depending on context.
• ovo pakovanje clearly means this package/pack, which already makes it definite.

The neutral, most straightforward order is:

• Ovo pakovanje je dovoljno.

But Serbian word order is more flexible than English, and changing the order can change the emphasis.

For example, you might hear other orders in context, but the basic learner-friendly version is the one given. It is the safest and most natural default.

Yes, if the context fits.

That sentence means roughly the same thing, but paket and pakovanje are not always identical.

Very roughly:

• paket often means a parcel, package, or set/bundle
• pakovanje often means a pack, container unit, or packaging/package form

So both may be possible in some contexts, but they are not perfect substitutes in every situation.

A useful approximate pronunciation is:

do-VOYL-no

The tricky part for English speakers is lj, which is a soft sound, similar to the lli in some pronunciations of million, though not exactly the same.

So try to keep lj as one soft consonant sound, not a full l plus j separately.
