شنطتي كانت ضايعة مبارح، بس هلا هي هون.

It is Levantine Arabic.

A few clear clues are:

• مبارح = yesterday in Levantine
  
  • In Modern Standard Arabic, you would usually see أمس
• هلا = now in Levantine
  
  • In MSA, you would usually see الآن
• هون = here in Levantine
  
  • In MSA, this is هنا
• بس often means but in spoken Levantine

So this sentence sounds natural in everyday spoken Levantine, not formal written Arabic.

A common Levantine-style pronunciation is:

shanṭti kānet ḍāyʿa mbāreḥ, bas hallaʾ hiyye hōn

You may also hear slightly different pronunciations depending on the region, for example:

• halla
• hallaʾ
• hiyye
• hī

A rough word-by-word pronunciation guide:

• شنطتي → shanṭti / sometimes shanṭeti
• كانت → kānet
• ضايعة → ḍāyʿa
• مبارح → mbāreḥ
• بس → bas
• هلا → halla / hallaʾ
• هي → hiyye
• هون → hōn

شنطتي means my bag.

It comes from:

• شنطة = bag
• ـي = my

So:

• شنطة
  • ـي → شنطتي

A useful thing to notice: the final ـة in شنطة changes in pronunciation when a suffix is added. That is why you get a t sound in شنطتي.

So the pattern is:

• شنطة = a bag
• شنطتي = my bag
• شنطك = your bag
• شنطتها = her bag

كانت means was, and it is the feminine singular past form of كان.

It is used because the subject, شنطتي (my bag), is grammatically feminine singular.

So:

• كان = was (masculine singular)
• كانت = was (feminine singular)

Since شنطة is feminine, Arabic uses:

• شنطتي كانت... = My bag was...

In the past, Arabic usually needs this verb to say was. That is why you see كانت in the first half of the sentence.

Because it describes شنطتي, and شنطة is a feminine noun.

So the adjective/state must agree with it:

• ضايع = lost / missing (masculine)
• ضايعة = lost / missing (feminine)

Since bag is feminine in Arabic, you say:

• شنطتي كانت ضايعة

not:

• شنطتي كانت ضايع

This is normal gender agreement in Arabic.

Yes—here ضايعة means something like:

• lost
• missing
• not where it should be

In everyday speech, it often means the item could not be found, not necessarily permanently lost forever.

So شنطتي كانت ضايعة مبارح can mean:

• My bag was lost yesterday
• My bag was missing yesterday
• I couldn’t find my bag yesterday

All of those are close in meaning, depending on context.

مبارح means yesterday.

In this sentence:

• شنطتي كانت ضايعة مبارح
  = My bag was lost yesterday

In Levantine, time words like مبارح are quite flexible. You could hear them in different places, for example:

• مبارح شنطتي كانت ضايعة
• شنطتي مبارح كانت ضايعة

The sentence you were given is very natural and easy to understand.

Here, بس means but.

So:

• ...مبارح، بس هلا...
  = ...yesterday, but now...

Important: بس can also mean only / just in other contexts.

For example:

• بس أنا = only me
• بس دقيقة = just a minute

So you always understand بس from context. In your sentence, it clearly means but.

Because in Arabic, the verb to be in the present tense is usually not spoken in sentences like this.

So:

• هي هون literally looks like she here
• but it means it is here

That is completely normal in Arabic.

Compare:

• شنطتي كانت ضايعة = My bag was lost
  → past tense, so كانت is used
• هي هون = It is here
  → present tense, so no spoken word for is

This is one of the most important patterns in Arabic nominal sentences.

Yes, هي is the feminine singular pronoun, often translated as she.

But in Arabic, objects also have grammatical gender. Since شنطة (bag) is feminine, the pronoun referring to it is هي.

So Arabic says:

• هي هون

even though in English you would normally say:

• it is here

So think of هي here as it, referring to a feminine noun.

In this sentence, هي sounds natural and helps keep the subject clear.

• بس هلا هي هون = but now it is here

Could you say it differently? Yes. For example:

• بس هلا الشنطة هون = but now the bag is here

In conversation, once the topic is already known, speakers often use the pronoun naturally:

• هي هون
• هو هون

So while Arabic often omits is, it does not necessarily omit the subject pronoun. Here هي works like it and makes the sentence sound complete and clear.

هون means here in Levantine Arabic.

Examples:

• أنا هون = I’m here
• هو هون = He/it is here
• هي هون = She/it is here

In Modern Standard Arabic, the equivalent is هنا.

So:

• هون = spoken Levantine
• هنا = formal / MSA

The word order is somewhat flexible, but the version you have is very natural:

• شنطتي كانت ضايعة مبارح، بس هلا هي هون.

You might also hear:

• شنطتي كانت ضايعة مبارح، بس هي هلا هون.
• مبارح شنطتي كانت ضايعة، بس هلا هي هون.

The choice often depends on what the speaker wants to emphasize.

For example:

• هلا هي هون puts focus on now
• هي هلا هون puts a bit more focus on it

So the sentence is not completely rigid, but the original order is a very normal spoken Levantine way to say it.
