Iubim acest oraș.

Iubim means we love.

It comes from the verb a iubi = to love.
The ending -im shows 1st person plural, so it means we.

A few present-tense forms are:

• eu iubesc = I love
• tu iubești = you love
• noi iubim = we love

So in Iubim acest oraș, the word iubim already tells you the subject is we.

Romanian often leaves out subject pronouns when they are not needed.

So instead of saying:

• Noi iubim acest oraș = We love this city

it is very common to say simply:

• Iubim acest oraș

Because iubim already means we love, the pronoun noi is optional.
If you include noi, it usually adds emphasis, like we love this city.

Acest means this.

In acest oraș, it is being used directly before a noun, so Romanian uses the shorter form:

• acest oraș = this city

Acesta is usually used when the word stands on its own, not directly before a noun:

• Acesta este orașul nostru. = This is our city.

So:

• acest
  • noun
• acesta by itself

Because oraș is a masculine noun in the singular.

Romanian demonstratives agree with the noun’s gender and number. So:

• acest = this (masculine singular)
• această = this (feminine singular)
• acești / aceste = these

Since oraș is masculine singular, you use acest:

• acest oraș = this city

Oraș means city.

A simple English-friendly pronunciation guide is roughly:

• o-RAHSH

The stress is on the second syllable: oRAȘ.

The letter ș is pronounced like sh in shoe.

So oraș sounds roughly like orash, with the final sound sh.

Because the sentence means We love this city, not We love the city.

In Romanian, this city is expressed with the demonstrative:

• acest oraș

If you wanted the city, you would normally say:

• orașul = the city

So compare:

• acest oraș = this city
• orașul = the city

You generally do not combine them in the same simple way as English this the city—that would not be correct here.

Yes. That is completely correct.

• Iubim acest oraș = We love this city.
• Noi iubim acest oraș = We love this city.

The version with noi is more explicit and can sound more emphatic.
The version without noi is very natural and common in Romanian.

Yes, Romanian word order is fairly flexible, although Iubim acest oraș is the most neutral and natural order here.

Possible variations include:

• Iubim acest oraș. = neutral
• Acest oraș îl iubim. = This city, we love it. / It is this city that we love.

Romanian often changes word order for emphasis or style.
For a learner, the basic pattern verb + object is a good default.

Romanian does not use a helper verb like English do in ordinary positive sentences.

English:

• We love this city.

Romanian:

• Iubim acest oraș.

The verb itself carries the meaning.
If you wanted emphasis, Romanian would usually use stress, word order, or extra words—not a direct equivalent of English supportive do in this sentence.

Often yes, but it can sound a bit strong depending on context.

A iubi is the normal verb for to love, and in a sentence like Iubim acest oraș, it sounds perfectly natural: We love this city.

Romanian can also use other verbs for weaker feelings, such as:

• a plăcea = to like
• ne place acest oraș = we like this city

So iubim expresses a stronger feeling than simply we like.

It is in the direct object role, so this is the accusative function.

In this sentence:

• Iubim = verb
• acest oraș = the thing being loved

For masculine singular nouns like oraș, the form here looks the same as the basic dictionary form, so you do not see a special ending change.

That means a learner can read it simply as:

• Iubim = we love
• acest oraș = this city

You would need both the noun and the demonstrative in the plural:

• Iubim aceste orașe. = We love these cities.

Changes:

• acest → aceste = this → these
• oraș → orașe = city → cities

So the singular/plural contrast is:

• Iubim acest oraș. = We love this city.
• Iubim aceste orașe. = We love these cities.
