Stația de lucru are un ecran mare.

Because Romanian usually puts the definite article at the end of the noun, not before it.

• stație = station / a station
• stația = the station

So stația de lucru means the workstation literally the station of work.

For feminine singular nouns like stație, the definite article is often -a:

• casă → casa = the house
• mașină → mașina = the car

de lucru literally means of work or for work, but in this phrase it forms a fixed expression:

• stație de lucru = workstation

Romanian often uses de to link nouns in this way:

• masă de cafea = coffee table
• sală de sport = gym / sports hall
• ochelari de soare = sunglasses

So you should understand stația de lucru as one unit: the workstation.

un is the indefinite article meaning a / an.

• ecran = screen
• un ecran = a screen

So:

• Stația de lucru are ecran mare would sound incomplete or unnatural here.
• Stația de lucru are un ecran mare = The workstation has a large screen

In Romanian, un is used with masculine and neuter singular nouns in the indefinite form.

are is the 3rd person singular form of the verb a avea = to have.

Conjugation of a avea in the present tense:

• eu am = I have
• tu ai = you have
• el/ea are = he/she/it has
• noi avem = we have
• voi aveți = you all have
• ei/ele au = they have

Since stația de lucru is a singular thing, Romanian uses are = has.

In Romanian, adjectives usually come after the noun.

So:

• un ecran mare = a large screen

This is the normal word order:

• o casă mare = a big house
• un birou mic = a small desk

Sometimes an adjective can come before the noun, but that is less neutral and may add emphasis or a stylistic effect. In ordinary speech, un ecran mare is the standard order.

Romanian adjectives agree with the noun, but mare has the same form for both masculine singular and feminine singular.

So:

• un ecran mare = a large screen
• o cameră mare = a large room

But in the plural it changes:

• ecrane mari = large screens
• camere mari = large rooms

So mare is already the correct singular form here.

ecran is a neuter noun in Romanian.

Romanian neuter nouns behave:

• like masculine in the singular
• like feminine in the plural

So:

• singular: un ecran
• plural: două ecrane

That is why the singular indefinite article is un, not o.

stație is a feminine noun.

You can see this in forms like:

• o stație = a station
• stația = the station

So the head noun in stația de lucru is feminine singular.

A helpful approximation is:

STAH-tsee-ah deh LOOK-roo AH-reh oon eh-KRAHN MA-reh

A few key points:

• ț is pronounced like ts in cats
• stația sounds roughly like STAH-tsee-ah
• lucru sounds like LOOK-roo
• ecran has stress on the second syllable: eh-KRAHN
• mare is MA-reh, not like English mare

Romanian spelling is fairly phonetic, so once you learn the sound of each letter, pronunciation becomes more predictable.

ț is pronounced ts, like the end of English cats.

So:

• stație sounds roughly like STAH-tsee-eh
• stația sounds roughly like STAH-tsee-ah

This is different from plain t. The comma under the letter matters:

• t = normal t
• ț = ts

Yes, Romanian often allows the subject to be omitted if it is clear from context, because the verb form already gives information.

So Are un ecran mare can mean It has a large screen, if everyone knows what it refers to.

But if you want to name the thing clearly, you say:

• Stația de lucru are un ecran mare.

Including the subject is normal and often clearer, especially when introducing new information.

The neutral, standard order is:

Stația de lucru + are + un ecran mare

Romanian can change word order for emphasis, but this version is the most natural in ordinary speech and writing.

For example, you might sometimes hear emphasis on the object, but for a learner, the safest pattern is:

Subject + verb + object

So this sentence is a good model to follow.

Because Romanian usually attaches the directly to the noun as an ending.

Compare English and Romanian:

• the station → stația
• the screen → ecranul

This is one of the big differences between Romanian and English. Instead of learning a separate word like the, you often need to learn the noun together with its definite ending.
