هي عم بتاكل تفاحة.

A word-by-word breakdown is:

• هي = she
• عم = a marker showing the action is in progress
• بتاكل = eats / is eating
• تفاحة = an apple

So the structure is basically:

she + progressive marker + eats + an apple

Yes, you often can leave it out.

In Levantine, the subject pronoun is frequently omitted if the verb already makes the meaning clear enough. So both of these can work:

• هي عم بتاكل تفاحة
• عم بتاكل تفاحة

Including هي can:

• make the subject extra clear
• add emphasis, like she is eating an apple
• help distinguish it from you are eating in contexts where the verb form could be ambiguous

عم is a very common Levantine way to show that something is happening right now or is ongoing.

So:

• بتاكل can mean she eats or sometimes she is eating, depending on dialect and context
• عم بتاكل clearly means she is eating

It works a lot like the English be + -ing idea, even though Arabic builds it differently.

بتاكل is the everyday Levantine present/imperfect form of the verb to eat.

A useful way to think about it is:

• the verb comes from the root related to eating
• the ت part is the person marker used for she in this tense
• in Levantine, the present tense often also includes بـ

So بتاكل is the normal colloquial form meaning she eats.

A helpful comparison:

• هي بتاكل = she eats / she is eating depending on context
• هي عم بتاكل = she is eating very clearly

Not really. In many Levantine varieties, this is normal.

• بـ is part of the ordinary present-tense verb form
• عم adds the idea of an action being currently in progress

So عم is not replacing the verb form; it is adding a specific meaning to it.

That said, spoken Levantine varies by region, and you may hear slightly different patterns from one country or city to another.

Because the subject is هي = she, and the verb agrees with it.

In this sentence, the verb form matches third-person feminine singular.

Compare:

• هي عم بتاكل = she is eating
• هو عم بياكل = he is eating

So the feminine form here is tied to the subject هي.

Yes. In Levantine, this form can also be used for you masculine singular.

So:

• هي بتاكل = she eats
• إنتَ بتاكل = you eat (to one male)

That means context or the pronoun tells you who the subject is.

With the pronoun included, there is no confusion:

• هي عم بتاكل = she is eating
• إنتَ عم بتاكل = you are eating (to one male)

Because تفاحة means an apple, while التفاحة means the apple.

Arabic does not usually use a separate word for a/an. Instead:

• تفاحة = an apple
• التفاحة = the apple

So the lack of الـ is what makes the noun indefinite here.

The sentence as written uses a very common spoken order:

هي + عم + بتاكل + تفاحة

This is natural and easy to understand in Levantine.

In everyday speech, you will very often hear:

• هي عم بتاكل تفاحة
• عم بتاكل تفاحة if the subject is understood

Compared with Standard Arabic, spoken Levantine generally prefers more straightforward subject-first patterns like this.

A common pronunciation is roughly:

hiyye ʿam btaakel tuffaaHa

A few notes:

• هي is often pronounced hiyye
• عم begins with ع, a deep throat sound that English does not have
• بتاكل often sounds like btaakel
• تفاحة is commonly pronounced tuffaaHa in Levantine

Pronunciation changes a bit by region, but that version is a good starting point.

This sentence is clearly colloquial Levantine, not formal Standard Arabic.

Main differences:

• Levantine uses عم to show an ongoing action
• the verb form بتاكل is colloquial pronunciation and grammar
• تفاحة is also pronounced differently in everyday speech than in careful Standard Arabic

A Standard Arabic sentence with the same basic meaning would be built differently. So this is the kind of sentence you would expect in normal conversation, not in formal news language or schoolbook Arabic.
