الممر فارغ.

In Arabic, the present-tense verb to be is usually not stated.

So الممر فارغ is literally something like the corridor empty, but it naturally means The corridor is empty.

If you want a different time, Arabic does use a verb:

• كان الممر فارغًا = The corridor was empty
• سيكون الممر فارغًا = The corridor will be empty

Because this is a sentence, not just a noun phrase.

• الممر = the corridor → definite
• فارغ = empty → here it is the predicate of the sentence, so it is normally indefinite

So:

• الممر فارغ = The corridor is empty
• الممر الفارغ = the empty corridor

That difference is very important in Arabic.

You would say:

الممر الفارغ

Here الفارغ is a true adjective describing الممر, so it must match it in definiteness. Since الممر has ال, the adjective must also have ال.

So compare:

• الممر فارغ = The corridor is empty
• الممر الفارغ = the empty corridor

A fully vocalized formal version is:

المَمَرُّ فارِغٌ

This shows that both parts are in the nominative case:

• المَمَرُّ = subject/topic
• فارِغٌ = predicate

In normal Arabic writing, these short vowels are usually not written, so you normally just see:

الممر فارغ

Also, at the end of a pause, speakers often do not pronounce the final case endings fully.

It is pronounced approximately:

al-mamarr
or in full formal reading, al-mamarru

A few helpful points:

• The ال is pronounced al-
• The word ممر is ma-marr
• The final r is effectively doubled in careful pronunciation, because the fully marked form is مَمَرّ

So the stress is roughly on the last part: al-ma-MARR.

No. In الممر, the ل is pronounced clearly.

That is because م is a moon letter, not a sun letter.

So you say:

al-mamarr

not

am-mamarr

Examples for comparison:

• الممر → al-mamarr because م is a moon letter
• الشمس → ash-shams because ش is a sun letter, so the l sound assimilates

The letter غ is pronounced far back in the mouth or throat. It is often described as a kind of voiced guttural fricative.

For many English speakers, a rough comparison is the French or German r, though it is not exactly the same.

So فارغ is approximately:

faa-righ

Important:

• It is not like English g in go
• It is a friction sound, not a stop

This is a nominal sentence in Arabic.

Its two parts are:

• الممر = the subject/topic
  In traditional Arabic grammar, this is the مبتدأ
• فارغ = the predicate/comment
  In traditional Arabic grammar, this is the خبر

So the structure is:

definite noun + predicate

This is one of the most basic and common sentence patterns in Arabic.

Yes. Since الممر is masculine singular, the predicate is also masculine singular:

• الممر فارغ

If the noun were feminine singular, you would use فارغة:

• الغرفة فارغة = The room is empty

So the form of the adjective/predicate changes to agree with the noun.

For a basic neutral sentence, الممر فارغ is the best order to learn first.

Arabic can sometimes change word order for emphasis or style, but that is less basic and can sound marked or literary. For a learner, the normal pattern here is:

الممر فارغ

So as a rule of thumb:

• use noun first
• then the predicate

That will sound natural and correct in straightforward MSA.
