Compania aeriană localizează bagajul de cală.

Because Romanian usually puts the definite article at the end of the noun.

• companie = company
• compania = the company
• bagaj = baggage / luggage
• bagajul = the baggage

This is one of the big differences from English: instead of a separate word like the, Romanian often adds it to the noun itself.

In Romanian, adjectives often come after the noun.

So:

• companie aeriană = airline / literally air company
• compania aeriană = the airline

This noun + adjective order is very common in Romanian, even though English usually does the opposite.

Because the adjective has to agree with the noun in gender and number.

Here:

• companie is feminine singular
• so the adjective must also be feminine singular
• therefore: aeriană

Compare:

• zbor aerian would not be right, because zbor is masculine and would take aerian
• companie aeriană is correct because companie is feminine

So the ending changes to match the noun.

Localizează is the 3rd person singular present tense of a localiza.

So it means:

• he/she/it locates
• the airline locates
• depending on context, it can also be translated as is locating

In this sentence, the subject is Compania aeriană, which is singular, so localizează is singular too.

Yes — in Romanian, a localiza commonly means to locate, to find the location of, or to identify where something is.

So in this sentence, it means the airline is finding or identifying the baggage’s location.

This is a good example where the Romanian verb looks like English localize, but in normal usage it often corresponds more directly to English locate.

Bagaj de cală is the usual expression for checked baggage, hold baggage, or luggage that goes in the cargo hold.

Breaking it down:

• bagaj = baggage / luggage
• cală = hold, cargo hold

So literally it is something like baggage of the hold, but in natural English you would usually say checked baggage or hold luggage.

Because in expressions like bagaj de cală, the second noun often stays indefinite.

So:

• bagaj de cală = hold baggage / checked baggage
• not bagaj de cala

Only the main noun here is definite:

• bagajul de cală = the checked baggage

This is a very common Romanian pattern:
noun + de + noun, where the second noun describes the type or category.

Because pe is not normally used for an ordinary inanimate direct object.

In Romanian, pe is often used with:

• people
• animate beings
• strongly specific direct objects, especially in certain contexts

But bagajul is an inanimate thing, so the normal form is simply:

• Compania aeriană localizează bagajul de cală.

No pe is needed.

Yes, but bagaj works a lot like English baggage or luggage: it can function as a collective or mass noun.

So bagajul can refer to baggage in general, not necessarily just one suitcase.

If you wanted to talk about separate individual items, Romanian could use other wording, but bagajul is perfectly normal here.

The given order is the most neutral and standard one:

• Compania aeriană = subject
• localizează = verb
• bagajul de cală = object

So it follows a normal subject–verb–object pattern.

Romanian word order can sometimes change for emphasis, but this version is the straightforward default and is what a learner should expect most often.

The letter ă is pronounced like the schwa sound in English — the unstressed sound in words like sofa or the a in about.

So:

• aeriană ends with -nə
• cală ends with -lə

This sound is very common in Romanian, so it is worth getting used to early. It is short, relaxed, and central — not a full a sound like in father.

Yes. Compania aeriană is a normal and standard Romanian phrase for airline.

Literally it means air company, but that is simply how Romanian expresses the idea. So you should learn it as a standard vocabulary item, not translate it word-for-word every time.
