جارنا طلع عالدرج لانه نسي المفتاح بالشقة.

جارنا means our neighbor.

It is made of:

• جار = neighbor
• ـنا = our

So literally: neighbor-our.

A learner note:

• جارنا usually refers to a male neighbor or to a neighbor in a general sense.
• If you specifically mean our female neighbor, you would usually say جارتنا.

Because in everyday Levantine, subject-first word order is very common.

So:

• جارنا طلع... = Our neighbor went up...

This is very natural in speech.

You could also hear:

• طلع جارنا...

That version is also possible, but it shifts the focus a bit more onto the action. In casual Levantine, both verb-first and subject-first orders exist, but subject-first is especially common.

Here طلع means went up, came up, or went upstairs.

With عالدرج, the whole idea is:

• طلع عالدرج = went up the stairs

This is a very common Levantine verb, and it is broader than a single English verb. In other contexts, طلع can also mean things like:

• came out
• appeared
• turned out

But in this sentence, the meaning is clearly went up.

The exact pronunciation depends on the Levantine variety, but common pronunciations include:

• ṭeleʿ
• ṭileʿ
• sometimes ṭalaʿ

Useful sound notes:

• ط is an emphatic t
• the final ع is the ʿayn sound, which has no exact English equivalent

So even if the spelling is the same, the vowels may differ a little by region.

عالدرج is a contracted colloquial form of:

• على الدرج = on/to the stairs

In Levantine, على often gets shortened before a noun, especially in fast everyday speech.

So:

• على الدرج → عالدرج

In this sentence, with طلع, it means:

• up the stairs
• onto the staircase

Because of sun-letter assimilation.

The noun is:

• الدرج

Since د is a sun letter, the l sound of الـ is not fully pronounced. So although it is written عالدرج, it is often pronounced more like:

• ʿad-daraj

This is normal in Arabic:

• written form keeps the ال
• spoken form assimilates it before sun letters

It can mean either, depending on context.

In everyday Levantine, الدرج often refers to:

• the stairs
• the staircase
• the stairway

So in this sentence, English would usually translate it as the stairs.

Yes. Here it means because.

You may see this word written in several ways in dialect writing, such as:

• لأنه
• لانو
• لإنه
• لانه

The spelling of colloquial Arabic is not fully fixed, so variation is normal.

In speech, many Levantine speakers say something like:

• laʔanno
• laʔenno
• laanno

For a learner, the easiest thing is to treat it as the conjunction because in this sentence.

It is already built into the verb.

• نسي = he forgot

In Arabic, past-tense verbs usually already contain the subject information, so you do not need a separate pronoun like he.

So:

• نسي المفتاح = he forgot the key

If you added هو, that would usually be for emphasis or contrast:

• هو نسي المفتاح = he is the one who forgot the key

A common Levantine pronunciation is:

• nese

In some varieties you may also hear:

• nisi

So the exact vowel can vary by region, but the meaning is the same:

• he forgot

Because it refers to a specific key.

• المفتاح = the key
• مفتاح = a key

In context, this is probably the key everyone would naturally understand, such as:

• the apartment key
• his key
• the house key

Arabic often uses the definite article when the object is known from context.

بالشقة means in the apartment or sometimes at the apartment, depending on context.

It is made of:

• بـ = in / at / with
• الشقة = the apartment

So:

• بالشقة = in the apartment

In Levantine, بـ is very commonly used for location, where English might use in or at.

So this is very natural colloquial Arabic.

A common urban Levantine pronunciation is:

• bish-shaʔʔa

Why?

• بـ often sounds like bi-
• الشقة has assimilation because ش is a sun letter
• ق in many urban Levantine accents is pronounced as a glottal stop ʔ

So the written form is بالشقة, but the spoken form may sound quite different from what an English speaker expects.

In many urban Levantine accents, ق is pronounced as a glottal stop:

• شقة → shaʔʔa

But this can vary by region. Some speakers may pronounce ق differently, including:

• q
• g

So the spelling stays the same, but pronunciation can change across Levantine dialects.

Usually it is understood as:

• he left the key in the apartment
• he forgot the key there

In other words, the key is still inside the apartment.

Arabic often expresses this idea with:

• نسي + object + place

So the sentence is not just about the mental act of forgetting; it strongly suggests that the key was forgotten in that location.

One possible Levantine-style transliteration is:

• jārna ṭeleʿ ʿad-daraj laʔanno nese l-miftāḥ bish-shaʔʔa

A few things may vary by region:

• ṭeleʿ / ṭileʿ
• nese / nisi
• pronunciation of ق in شقة

So do not worry if you hear slightly different versions from different speakers.
