Pasagerul așteaptă controlul.

-ul is the definite article for many masculine and neuter singular nouns in Romanian. It corresponds to English the, but in Romanian it is usually attached to the end of the noun instead of standing in front of it.

So:

• pasager = passenger / a passenger
• pasagerul = the passenger

and

• control = check / inspection / control
• controlul = the check / the inspection

This is a very common feature of Romanian:

• băiat → băiatul = the boy
• student → studentul = the student

Because Romanian usually uses a postposed definite article: the article is added to the end of the noun.

So instead of English the passenger, Romanian says pasagerul.

This is one of the first big differences English speakers notice in Romanian.

Because the Romanian verb a aștepta usually takes a direct object. English says wait for someone/something, but Romanian normally just says aștepta pe cineva / aștepta ceva.

So:

• aștept trenul = I’m waiting for the train
• așteaptă autobuzul = he/she is waiting for the bus
• pasagerul așteaptă controlul = the passenger is waiting for the check/inspection

This is very natural Romanian. English needs for, but Romanian usually does not here.

Așteaptă is the 3rd person singular present tense of a aștepta = to wait.

It can mean:

• he waits
• she waits
• it waits

In this sentence, it goes with pasagerul, so it means the passenger waits / is waiting.

A quick mini-pattern:

• eu aștept = I wait
• tu aștepți = you wait
• el/ea așteaptă = he/she waits
• noi așteptăm = we wait
• voi așteptați = you all wait
• ei/ele așteaptă = they wait

In this sentence, the most natural reading is:

• pasagerul = subject
• controlul = direct object

That is mainly because of:

1. word order — Romanian often puts the subject before the verb
2. meaning/context — it makes more sense that a passenger is waiting for an inspection/check

Formally, for masculine singular nouns like these, the nominative and accusative forms are often identical, so the endings alone do not always tell you which is which.

So context and word order help a lot.

Sometimes control in Romanian can mean control, but in sentences like this it very often means inspection, check, or ticket/security/passport control, depending on context.

So here controlul is more likely something like:

• the inspection
• the check
• the control/checkpoint procedure

For example, in travel contexts:

• control de securitate = security check
• control pașapoarte = passport control
• control bilete = ticket inspection

So an English speaker should be careful: control is not always used exactly like English control.

Romanian often uses pe before a direct object when that object is a specific person or a personal pronoun.

Examples:

• Aștept trenul. = I’m waiting for the train.
• Îl aștept pe profesor. = I’m waiting for the professor.
• Îl aștept pe el. = I’m waiting for him.

Since controlul is a thing, not a person, pe is not used.

So așteaptă controlul is exactly what you would expect.

The dictionary forms are:

• pasager = passenger
• control = check, inspection, control

The -ul is added only when the noun is definite.

So if you look these words up in a dictionary, you usually look for pasager and control, not pasagerul and controlul.

A rough pronunciation guide:

• ș sounds like English sh
• ă is a short central vowel, somewhat like the a in about, but shorter and clearer

So așteaptă is roughly: uh-SHTEAP-tuh

More carefully:

• aș = uhsh
• teap = like tyap/teap
• tă = tuh with Romanian ă

The stress is on the middle syllable: aș-TEAP-tă

A simple approximate pronunciation is:

pa-sa-JER-ul uh-SHTEAP-tuh kon-TRO-lul

A few notes:

• g in pasagerul sounds like the s in measure
• r is usually rolled or tapped
• ă is the short neutral vowel described above

Stress:

• pasaGERul
• aȘTEAPtă
• conTROlul

Yes, Romanian word order is somewhat flexible, although not completely free.

The neutral order is:

• Pasagerul așteaptă controlul.

But depending on emphasis, you might also hear other orders in broader contexts. Still, for a basic standalone sentence, the given order is the most natural and easiest for learners.

So if you are just learning, treat:

subject + verb + object

as the safest default.

It can mean either, depending on context.

Romanian present tense often covers both:

• he waits
• he is waiting

So:

Pasagerul așteaptă controlul.

can be understood as:

• The passenger waits for the check or
• The passenger is waiting for the check

English chooses between simple present and present continuous more often than Romanian does.

Because it has the definite article -ul, it usually sounds like a specific check/inspection:

• the check
• the inspection

If you wanted something more indefinite, you would normally use control without -ul in the right context.

So the sentence suggests that the speaker has a particular check in mind, not just the abstract concept of inspection.

Yes, grammatically it is natural.

That said, in real life, Romanian speakers might often use a more specific phrase depending on the situation, such as:

• controlul de securitate = the security check
• controlul pașapoartelor = passport control
• controlul biletelor = ticket inspection

So Pasagerul așteaptă controlul. is correct, but in actual context people may prefer a more precise noun phrase.
