Ana restituie exemplarul vineri.

Restituie means returns / gives back.

Its dictionary form is a restitui, which is the infinitive, equivalent to to return or to give back in English.

In this sentence, restituie is the 3rd person singular present tense form, so it agrees with Ana:

• Ana restituie = Ana returns

Yes. Romanian often allows the subject to be omitted because the verb ending already gives information about the person and number.

So both of these are possible:

• Ana restituie exemplarul vineri.
• Restituie exemplarul vineri.

Including Ana makes the subject explicit, just like in English. Leaving it out would be natural if the context already makes clear who is returning it.

Exemplarul usually means the copy or the specimen/example, depending on context.

Very often, in everyday Romanian, it can refer to:

• a copy of a book
• a library copy
• an issue of a publication
• a particular item or specimen

So in a practical sentence like this, it often means something like the copy.

Because -ul is the Romanian definite article attached to the end of the noun.

So:

• exemplar = a copy / a specimen
• exemplarul = the copy / the specimen

Unlike English, Romanian usually puts the definite article at the end of the noun:

• băiat = boy
• băiatul = the boy

The same pattern appears here:

• exemplar → exemplarul

Romanian normally uses an enclitic definite article, which means the article is attached to the end of the noun instead of appearing as a separate word before it.

So English says:

• the copy

Romanian says:

• exemplarul

This is one of the major structural differences between Romanian and English.

In this sentence, exemplarul is the direct object of restituie.

For many Romanian nouns, especially inanimate masculine/neuter nouns, the nominative and accusative forms are identical. So the form does not change here.

That means:

• subject form: exemplarul
• direct object form: exemplarul

Romanian often relies on context, word order, and meaning to show the noun’s role.

Because pe is generally used before specific animate direct objects, especially people.

For example:

• Văd pe Ana. = I see Ana.

But with an inanimate object like exemplarul, Romanian normally does not use pe:

• Ana restituie exemplarul.

So the absence of pe is exactly what you would expect here.

Here vineri means on Friday.

Romanian often uses the day of the week without a preposition where English uses on:

• luni = on Monday
• marți = on Tuesday
• vineri = on Friday

So:

• Ana restituie exemplarul vineri. = Ana returns the copy on Friday.

Depending on context, vineri can sometimes also be understood more generally as Fridays, but in a simple sentence like this it is often read as on Friday.

Because Romanian usually does not need one with days of the week in this kind of time expression.

English says:

• on Friday

Romanian typically just says:

• vineri

This is normal and very common.

Grammatically, restituie is in the present tense, but Romanian present tense can also express a scheduled future or a near future, depending on context.

So this sentence can mean either:

• Ana returns the copy on Friday
  or
• Ana is returning / will return the copy on Friday

If the broader context is about a planned action, English might translate it with a future idea even though Romanian uses the present.

The given order is perfectly natural:

• Ana restituie exemplarul vineri.

But Romanian word order is more flexible than English, so other orders are possible depending on emphasis:

• Vineri, Ana restituie exemplarul.
• Exemplarul Ana îl restituie vineri. (more marked, with emphasis)

The basic version is the best neutral choice for learners:

• Subject + Verb + Object + Time

Because Ana is third person singular, and restituie is the present tense form used for he/she/it.

So:

• eu restitui = I return
• tu restitui = you return
• el/ea restituie = he/she returns

Since Ana is a singular person, Romanian uses restituie.

A learner-friendly pronunciation is roughly:

res-ti-TU-ye

The last part, -uie, is pronounced like two syllabic elements flowing together, approximately oo-ye.

So the whole sentence is roughly:

• A-na res-ti-TU-ye eg-zem-PLA-rul VI-neri

The exact sounds depend on accent and speed, but that approximation is good enough for a beginner.

Only if the context makes clear that exemplarul refers to a particular copy of a book.

By itself, exemplarul does not literally mean book. It means the copy / the specimen / the item. But in real-life contexts, especially libraries or schools, English might translate it more naturally as:

• the copy
• the book copy
• sometimes even just the book, if that is what the copy clearly is

So the exact English wording depends on context, even though the Romanian noun stays the same.
