مبارح حضرت اول حلقة من مسلسل جديد، وكانت الحلقة منيحة كتير.

مبارح means yesterday.

It is a very common word in Levantine Arabic, but it is dialectal, not Modern Standard Arabic. In MSA, you would usually say أمس.

So:

• مبارح = everyday Levantine
• أمس = formal/standard Arabic

That is a very good question. The verb حضر originally has the idea of attending or being present at, but in Levantine it is also commonly used for watching things like:

• a movie
• a series
• an episode
• a show
• a lecture

So حضرت اول حلقة means something like:

• I watched the first episode
• literally, closer to I attended/saw the first episode

A very common alternative would be شفت:

• مبارح شفت اول حلقة... = Yesterday I watched the first episode...

Because Arabic verbs already include the subject.

حضرت here already tells you I watched from the verb form, so أنا is not necessary. Arabic often leaves subject pronouns out unless they are needed for:

• emphasis
• contrast
• clarity

So both are possible:

• حضرت اول حلقة = I watched the first episode
• أنا حضرت اول حلقة = I watched the first episode with extra emphasis on I

Yes, it can be.

Without vowel marks, حضرت can represent more than one form, depending on context. In spoken Levantine, context usually makes it clear whether it means:

• I watched/attended
• she watched/attended
• sometimes another form depending on dialect and pronunciation

In this sentence, the meaning is understood from context as I watched.

This kind of ambiguity is very common in normal Arabic writing.

In everyday Levantine, أول / اول is the normal way to say first before a noun.

So:

• اول حلقة = the first episode
• اول مرة = the first time
• اول يوم = the first day

A few useful notes:

• The spelling اول without hamza is very common in casual writing.
• In speech, it is usually pronounced awwal.
• In colloquial Arabic, this structure is much simpler than the more formal patterns you may have seen in Standard Arabic.

Because Arabic and English handle this idea differently.

In Levantine, أول + noun often naturally means the first noun without needing ال on the noun. So اول حلقة is a normal way to say the first episode.

English uses the, but Arabic does not always match that word-for-word.

So:

• اول حلقة = the first episode

This is just a normal Arabic pattern, not a mistake.

Literally, it means from a new series, but in natural English we say of a new series.

So:

• حلقة من مسلسل = an episode of a series
• مسلسل جديد = a new series

Also notice the adjective order:

• مسلسل جديد = series new
• Arabic normally puts the adjective after the noun

So the whole chunk means:

• the first episode of a new series

Because the speaker is describing something in the past.

In Arabic, a sentence like:

• الحلقة منيحة كتير
  means
• The episode is very good

To move that idea into the past, Levantine uses كان:

• كانت الحلقة منيحة كتير = The episode was very good

So كانت is doing the job of was.

Because once the episode has been introduced, it becomes a specific known thing.

First mention:

• اول حلقة من مسلسل جديد = the first episode of a new series

Second mention:

• الحلقة = the episode

This is similar to English:

• first you say an episode
• then you say the episode

So the second clause refers back to the same episode and makes it definite.

Because حلقة is a feminine noun, and the adjective has to agree with it.

So:

• منيح = masculine good
• منيحة = feminine good

Since حلقة is feminine, you say:

• الحلقة منيحة

If the noun were masculine, you would use منيح:

• المسلسل منيح = The series is good

Here, كتير means very.

So:

• منيحة كتير = very good

In Levantine, كتير often comes after the adjective:

• حلو كتير = very nice
• صعب كتير = very difficult
• منيحة كتير = very good

This is different from English, where very comes before the adjective.

A simple transliteration would be:

mbaareḥ ḥaḍart awwal ḥalʔa min musalsal jdiid, w kaanet il-ḥalʔa منيحة ktiir

A more natural pronunciation note:

• مبارح = mbaareḥ
• حضرت = ḥaḍart
• اول = awwal
• حلقة = ḥalʔa
• جديد = jdiid
• كتير = ktiir

Exact pronunciation varies a bit by country and city, but this is a good general Levantine reading.

Yes, absolutely.

Both are natural, but they feel slightly different:

• شفت اول حلقة = I saw/watched the first episode
• حضرت اول حلقة = I watched/attended the first episode

In many everyday situations, شفت may sound a bit more common and direct for watched, especially for TV content. But حضرت is also very understandable and natural in Levantine.
