Fac ordine în camera de zi înainte să vină oaspeții.

Romanian often drops subject pronouns when the verb already shows who is doing the action.

• fac = I do / I make
• so eu is not necessary

You could say Eu fac ordine... if you want emphasis, but the normal neutral sentence is just Fac ordine...

Fac ordine is a very common Romanian expression meaning:

• I tidy up
• I put things in order
• I clean up in the sense of organizing

Literally, it is something like I make order, but in natural English you would usually say I tidy up or I straighten up.

Because a face ordine is a fixed idiomatic expression. In this expression, ordine is normally used without the article.

So:

• fac ordine = I tidy up / I put things in order

Using ordinea here would sound unnatural in ordinary Romanian.

Word by word:

• în = in
• camera = the room
• de zi = for daytime / of day

But as a full expression, camera de zi means the living room.

So în camera de zi means in the living room.

Because camera is the definite singular form of cameră.

• cameră = a room
• camera = the room

Romanian puts the definite article at the end of the noun, not as a separate word like English the.

So:

• în cameră = in a room / in the room, depending on context
• în camera de zi = in the living room

Înainte să means before when it introduces a clause with a verb.

So:

• înainte să vină oaspeții = before the guests come

Romanian also has a longer version:

• înainte ca oaspeții să vină

Both mean the same thing here. The shorter înainte să is very common in everyday speech.

Because after să, Romanian normally uses the subjunctive.

Here:

• a veni = to come
• vine = he/she comes
• să vină = that he/she come / to come, in a subjunctive construction

After înainte să, Romanian uses this să + subjunctive pattern:

• înainte să vină = before ... comes

So înainte să vine would be incorrect.

Because oaspeții is the definite plural form of oaspete.

The forms are:

• oaspete = guest
• oaspeți = guests
• oaspeții = the guests

The ending -ii can look strange at first, but it happens because:

• one i belongs to the plural form
• the other i marks the definite article

So oaspeții means the guests, not just guests.

Because oaspeții refers to specific guests the speaker has in mind, for example guests who are expected to arrive soon.

So the sentence suggests something like:

• I’m tidying up before the guests come

If you said oaspeți, that would be more indefinite or less specific.

Romanian word order is fairly flexible, and in this structure verb + subject is very natural:

• înainte să vină oaspeții

It sounds smooth and normal in everyday Romanian.

If you want the subject before the verb, Romanian often prefers the longer structure:

• înainte ca oaspeții să vină

So in this sentence, să vină oaspeții is the most natural version.

Grammatically, fac is present tense. But in meaning, it can work in a few ways depending on context:

• I am tidying up the living room before the guests come
• I tidy up the living room before the guests come
• sometimes even I’ll tidy up the living room before the guests come, if the context makes it clear

Romanian present tense is often used where English might choose either present or future-like wording.

No. Camera de zi is correct and clear, but Romanian speakers also often say:

• sufragerie

Both can mean living room, though usage can vary by region and by exactly what kind of room is meant. In a learning context, camera de zi is a very useful standard expression.
