خزانة الأمتعة عند مدخل المتحف.

A careful MSA pronunciation is:

khizānatu al-amtiʿati ʿinda madkhali al-matḥafi

A very common pause-style pronunciation without full case endings is:

khizānat al-amtiʿa ʿind madkhal al-matḥaf

A few sound notes:

• خ = a rough kh sound, like the ch in Scottish loch
• ع = the deep throat sound ʿayn
• ح = a stronger, breathier h
• ة at the end of خزانة is often pronounced -t here because the word is in a construct phrase

Because Arabic usually leaves out the present-tense verb to be.

So a sentence like this does not need a separate word for is. Arabic simply puts the parts next to each other:

• خزانة الأمتعة = the luggage storage / the baggage locker
• عند مدخل المتحف = at the entrance of the museum

This is a normal nominal sentence in Arabic.

It is an iḍāfa construction, often called a construct phrase.

In an iḍāfa:

• the first noun is possessed or specified by the second noun
• the first noun does not take ال
• the second noun is in the genitive

So:

• خزانة الأمتعة literally means something like the cabinet/storage of the luggage
• naturally, this becomes the luggage locker, baggage storage, or similar

Because in an iḍāfa, the first noun normally does not take ال.

So Arabic says:

• خزانة الأمتعة

not:

• الخزانة الأمتعة

The definiteness of the whole phrase comes from the second noun. Since الأمتعة is definite, the whole phrase is definite.

In this sentence, الأمتعة is the second part of an iḍāfa, and it is marked as definite with ال.

That makes the whole phrase definite:

• خزانة الأمتعة = the luggage storage / the baggage locker

If the second noun were indefinite, the whole phrase would be indefinite.

It is a plural noun.

• singular: متاع = belongings, goods, baggage
• plural: أمتعة = luggage, baggage, belongings

Even though English often treats luggage as an uncountable noun, Arabic uses this plural form very naturally.

Here عند means at, by, or near.

So:

• عند مدخل المتحف = at the museum entrance / by the entrance of the museum

It often gives a sense of location near a point.

Because عند and في are not exactly the same.

• عند = at/by/near
• في = in/inside

So عند مدخل المتحف suggests a location at the entrance area. If you said في مدخل المتحف, it would sound more like inside the entranceway itself.

For a sign or location marker, عند is often the more natural choice.

It is another iḍāfa construction:

• مدخل = entrance
• المتحف = the museum

So:

• مدخل المتحف = the entrance of the museum = the museum entrance

Arabic uses iḍāfa very often where English uses of or a noun-noun phrase.

That final letter is taa marbuuṭa (ة).

Its pronunciation depends on context:

• in pause, it is often pronounced -a or -ah
• when the word is connected grammatically to what follows, especially in an iḍāfa, it is pronounced -t

So here, because it is part of خزانة الأمتعة, you will often hear:

• khizānat al-amtiʿa

not just:

• khizāna al-amtiʿa

With full case endings, it is:

خِزانَةُ الأَمْتِعَةِ عِندَ مَدْخَلِ المَتْحَفِ

Here is why:

• خزانةُ = nominative, because it is the topic/start of the nominal sentence
• الأمتعةِ = genitive, because it is the second term of an iḍāfa
• عندَ = accusative as an adverbial noun of place
• مدخلِ = genitive after عند in this construction
• المتحفِ = genitive as the second term of مدخل المتحف

In everyday reading and speech, these endings are often not pronounced fully.

It can function as either, depending on context.

As a full sentence, it means something like:

• The luggage locker is at the museum entrance.

As a sign, it can simply label the location:

• Luggage storage — at the museum entrance

Arabic often uses short noun phrases like this very naturally on signs and notices.

That is very normal in Arabic. Arabic often chains nouns together using iḍāfa instead of using words like of.

In this sentence you have:

• خزانة الأمتعة = luggage storage
• مدخل المتحف = museum entrance

So the sentence is built mostly from noun phrases rather than from verbs or prepositions the way English often would be.

The structure is:

• خزانة الأمتعة = the subject/topic
• عند مدخل المتحف = the location/predicate

So the pattern is:

• [noun phrase] + [location phrase]

This is a very common Arabic pattern for saying where something is.

Yes. مدخل is related to the root د-خ-ل, which has to do with entering.

So:

• دخل = he entered
• مدخل = entrance, entry point

This is a common feature of Arabic: many nouns are built from verbal roots, so learning roots can help you recognize related words more easily.
