عملت لستة للحفلة فيها الاكل والشاي والعصير.

Yes. In normal Arabic writing without short vowels, عملت can represent both:

• I made / I did
• she made / she did

The context tells you which one is meant. If the speaker wants to make it clear, they can add a pronoun:

• أنا عملت = I made
• هي عملت = she made

This kind of ambiguity is very common in Arabic script.

Yes—it's a very common colloquial word, borrowed from European languages, meaning list.

In Levantine, people often say لستة instead of the more formal/standard Arabic قائمة.

So:

• لستة = everyday spoken list
• قائمة = more formal / MSA list

A learner should definitely recognize لستة, because people use it a lot in speech.

Because this is لـ + الـ:

• لـ = for / to
• الحفلة = the party

Together they become:

• للحفلة = for the party

This merging is normal in Arabic spelling. So ل + ال becomes لل.

Literally, فيها means in it.

But in sentences like this, it often works like:

• it has
• it contains
• there is/are in it

So here فيها الأكل والشاي والعصير means something like:

• it has food, tea, and juice
• it includes food, tea, and juice

This is a very natural Arabic way to express contents.

The -ها means it / her in the feminine form. Here it refers to لستة.

So:

• في = in
• ها = it (feminine)

Together:

• فيها = in it

Why feminine? Because لستة is treated as a feminine noun, which is very common for nouns ending in ـة.

In Arabic, especially when talking about categories or general items, nouns often appear with الـ even when English would usually leave them without the.

So Arabic says:

• الأكل = literally the food
• الشاي = literally the tea
• العصير = literally the juice

But in natural English translation, this often becomes simply:

• food, tea, and juice

So the Arabic definite article here does not necessarily mean very specific, already-known individual items. It can just mark the category naturally.

In formal spelling, yes, الأكل is the standard spelling.

In everyday Arabic writing, especially in texts, chats, or informal dialect writing, people often leave out the hamza and write:

• الاكل

So:

• الأكل = formal / standard spelling
• الاكل = very common informal spelling

Both are easy to understand.

Because ش is a sun letter. With sun letters, the l of الـ assimilates to the next consonant.

So:

• written: الشاي
• pronounced more like: ash-shāy or ish-shāy (depending on dialect)

You do not normally say a full al-shāy in careful everyday speech.

This happens with many words that begin with sun letters.

Usually they mean general categories here.

So the sentence suggests the list includes things like:

• food
• tea
• juice

It does not necessarily mean one specific food item, one specific tea, and one specific juice. It sounds more like the speaker is listing broad contents or categories for the party.

Because in this sentence they are being used as mass nouns, just like in English.

Compare English:

• food
• tea
• juice

These are often uncountable when you mean them generally. Arabic works similarly here:

• الأكل
• الشاي
• العصير

If the speaker wanted to emphasize kinds or servings, they might choose different wording, but the singular/general form is the normal choice in this sentence.

One natural Levantine-style pronunciation would be something like:

ʿamalt liste lal-ḥafle, fīha l-akel w-sh-shāy w-l-ʿaṣīr

A few notes:

• عملت may sound like ʿamalt or ʿemelt, depending on region
• لستة is often pronounced liste
• الشاي becomes sh-shāy because of assimilation
• و is usually just a quick w-

Exact pronunciation varies across Syria, Lebanon, Palestine, and Jordan, but that gives you the general Levantine feel.
