Maayos ang kondisyon ng apartment.

Because Filipino often puts the predicate first.

So the sentence structure is:

Maayos = the predicate, meaning good / okay / in good condition
ang kondisyon ng apartment = the topic/subject, meaning the condition of the apartment

So this is a very normal Filipino pattern:

Maayos ang kondisyon ng apartment.
= The apartment’s condition is good.

In English, we usually start with the subject. In Filipino, starting with the predicate is very common.

Ang is a marker that points to the topic/subject of the sentence.

In this sentence, ang marks kondisyon ng apartment as the main noun phrase being talked about:

ang kondisyon ng apartment = the condition of the apartment

It does not mean the exactly, although it can sometimes feel similar in translation. Its real job is grammatical: it marks the noun phrase that the sentence is centered on.

Here, ng shows a relationship like of in English.

So:

kondisyon ng apartment = condition of the apartment
or more naturally, the apartment’s condition

In this phrase:

• kondisyon = condition
• ng apartment = of the apartment

So ng is marking apartment as the possessor or related noun.

Yes. It is one noun phrase.

The head noun is kondisyon, and ng apartment tells you whose condition it is.

So the structure is:

• ang = marks the whole phrase
• kondisyon = main noun
• ng apartment = modifier meaning of the apartment

Together:

ang kondisyon ng apartment = the condition of the apartment

Because in this sentence, maayos is not directly modifying kondisyon inside the noun phrase. It is the predicate of the whole sentence.

So:

Maayos ang kondisyon ng apartment.
= The condition of the apartment is good.

If you wanted maayos to directly modify kondisyon, then you would use na:

ang maayos na kondisyon ng apartment

That would mean something like the good condition of the apartment, which is a noun phrase, not a full sentence by itself.

So the difference is:

• Maayos ang kondisyon ng apartment. = full sentence
• ang maayos na kondisyon ng apartment = noun phrase

Yes. That is also correct.

Compare:

Maayos ang kondisyon ng apartment.
Ang kondisyon ng apartment ay maayos.

Both mean the same thing.

The first one is the more common predicate-first order.
The second one uses ay, which often appears in a more formal, careful, or emphasized style.

So:

• Maayos ang kondisyon ng apartment. = very normal
• Ang kondisyon ng apartment ay maayos. = also correct, slightly more formal or textbook-like

In this sentence, maayos means something like:

• in good condition
• okay
• well-kept
• fine

The exact English translation depends on context.

Maayos can also mean orderly, neat, or proper, but here it is describing the condition of the apartment, so in good condition is a very natural interpretation.

Yes, it is commonly used in Filipino, especially in everyday modern speech.

Filipino uses many borrowed words, especially for housing, technology, business, and urban life. So apartment sounds natural.

You may also see more localized or alternative forms in some contexts, but apartment is very normal and widely understood.

As a separate word like this, ng is usually pronounced roughly like nang.

So:

Maayos ang kondisyon ng apartment
would sound roughly like:
ma-A-yos ang kon-di-SYON nang a-PART-ment

Important note:

• When ng is a word/marker, it is usually pronounced nang
• When ng is part of a syllable or letter name, it can represent the ng sound in sing

Here, in ng apartment, it is the grammatical marker, so think of it as nang.

Yes. A very natural alternative is:

Nasa maayos na kondisyon ang apartment.

This means almost the same thing:
The apartment is in good condition.

Compare:

Maayos ang kondisyon ng apartment.
= The condition of the apartment is good.

Nasa maayos na kondisyon ang apartment.
= The apartment is in good condition.

Both are natural. The second one may sound a little more directly like the English idea of is in good condition.
