عزمت صديقتي وصديقتها عالعشا بالمسا.

In normal Arabic spelling, عزمت can represent both I invited and she invited, because short vowels are usually not written.

So learners have to rely on:

• context
• the given meaning
• the rest of the sentence

This kind of ambiguity is very common in Arabic.

Both come from صديقة, which means female friend.

The endings are possessive suffixes:

• صديقتي = my friend
• صديقتها = her friend

So:

• -ي = my
• -ها = her

Yes. The nouns صديقتي and صديقتها both refer to female friends, and عزمت can match a feminine singular subject.

If you were talking about a male friend, you would use forms like:

• صديقي = my male friend
• صديقه = his friend or her male friend, depending on context

Normally, و means and.

So صديقتي وصديقتها most naturally looks like: my friend and her friend

That means the sentence as written is a bit ambiguous. If the intended meaning is my friend invited her friend, many speakers would expect: عزمت صديقتي صديقتها... without the و.

So this is a good example of how the written form and the intended meaning do not always line up perfectly in casual Arabic.

عالعشا is a spoken contraction of على العشا.

In Levantine, على + الـ often becomes عالـ in fast everyday speech.

So:

• على العشا → عالعشا

It means to dinner or for dinner, depending on the sentence.

العشا is the common colloquial Levantine form.

The more formal or Standard Arabic form is:

• العشاء

In everyday speech, Levantine often shortens words and smooths out endings, so العشا sounds much more natural in conversation.

بالمسا means in the evening.

It breaks down like this:

• بـ = in / at
• المسا = the evening

So بالمسا literally means in the evening.

In more formal Arabic, you would often see:

• في المساء

Arabic often uses verb-first word order, especially in straightforward statements.

So starting with عزمت is very normal. Levantine can also use subject-first order, but verb + subject is common and natural.

That means a sentence like this can begin with the action first, then mention who did it.

The letter ع is the Arabic sound called ʿayn. English does not have an exact equivalent.

It is pronounced deep in the throat, not like a normal English vowel. For beginners, the most important thing is to notice that it is a real consonant, not silent.

So in:

• عزمت
• عالعشا

you should try not to skip the ع, even if your pronunciation is not perfect yet.

In many Levantine accents, especially urban ones, ق is often pronounced as a glottal stop.

So صديقتي is often pronounced roughly like: ṣadīʔti

rather than: ṣadīqti

Both are connected to the same written word, but the glottal stop pronunciation is very common in Levantine speech.

A more formal version would usually use:

• على العشاء instead of عالعشا
• في المساء instead of بالمسا

So these parts of the sentence are very clearly colloquial Levantine, not formal written Arabic.
