الممثلة كانت عم تحكي مع الممثل بعد الحلقة.

Because الممثلة is feminine singular.

In Levantine, كان changes for gender in the past:

• كان = he was
• كانت = she was

So with الممثلة (the actress), you use كانت.

This is also part of a very common pattern:

• كان/كانت + عم + imperfect verb
  = was/were doing

So كانت عم تحكي means she was talking.

عم marks an action as ongoing or in progress.

So:

• تحكي = talks / talk / speak, depending context
• عم تحكي = is talking
• كانت عم تحكي = was talking

It is one of the most common ways to make the progressive in Levantine.

A useful comparison:

• بتحكي عربي = she speaks Arabic / she speaks Arabic generally
• عم تحكي عربي = she is speaking Arabic right now
• كانت عم تحكي عربي = she was speaking Arabic

Yes. تحكي is the correct imperfect form for a feminine singular subject in this sentence.

The base verb is حكى / يحكي. In this pattern:

• هو يحكي = he talks
• هي تحكي = she talks

So because the subject is الممثلة, you get تحكي.

Also, after عم, many Levantine speakers use the verb without بـ:

• عم تحكي

That is why you do not see بتحكي here.

Yes. In Levantine, حكى / يحكي is very common in everyday speech for to talk / speak / say.

Depending on context, it can mean:

• talk
• speak
• say
• sometimes tell

So تحكي مع الممثل naturally means talk to / talk with the actor.

This can surprise learners who know more Standard Arabic, where حكى may feel more like narrate or tell. In Levantine, it is much broader and very everyday.

Yes, both can exist, but the nuance and dialect preference can vary.

• كانت عم تحكي = very clear was talking
• كانت تحكي = can mean was talking, but can also sometimes feel more like used to talk / would talk, depending on context
• كانت عم بتحكي = also heard in some Levantine varieties

So the sentence you have is a very natural way to express an ongoing past action.

In short:

• عم makes the progressive meaning clearer
• some speakers keep بـ after عم
• some speakers drop it, as in your sentence

Because both nouns are definite: the actress and the actor.

• ممثلة = an actress
• الممثلة = the actress
• ممثل = an actor
• الممثل = the actor

Using ال usually means these are specific people already known from context.

So:

• الممثلة كانت عم تحكي مع الممثل
  means a specific actress was talking with a specific actor.

مع means with.

So:

• تحكي مع = talk with / talk to

This is a very common combination in Levantine:

• حكيت معو = I talked with him
• عم تحكي معي = she is talking with me
• كانوا عم يحكوا مع بعض = they were talking with each other

In English, talk with and talk to are slightly different sometimes, but in Arabic مع works very naturally here.

بعد means after, and الحلقة means the episode.

So the structure is simply:

• بعد + noun

Examples:

• بعد الحلقة = after the episode
• بعد الفيلم = after the movie
• بعد الشغل = after work

Because الحلقة is definite, it means a specific episode.

So:

• بعد الحلقة = after the episode
• بعد حلقة would sound like after an episode, which is less likely here

The word order is flexible.

Your sentence starts with the subject:

• الممثلة كانت عم تحكي...

That is very natural in spoken Levantine.

You could also say:

• كانت الممثلة عم تحكي...

That is also possible, but it may sound a bit more narrative, formal, or context-driven depending on how it is used.

In everyday Levantine, subject-first order is extremely common, especially when you are just stating what happened.

In these words, the ل of ال is pronounced, because the following letters are moon letters, not sun letters.

So:

• الممثلة
• الممثل
• الحلقة

all keep the l sound of the article.

In Levantine pronunciation, ال is often heard more like el- or il- rather than Standard Arabic al-.

So roughly:

• el-m...
• el-ḥ...

not something assimilated like ash-sh...

No. In spoken Levantine, you do not use the Standard Arabic case endings.

So you would not pronounce final endings like:

• -u
• -a
• -i

on these words in normal speech.

That means this sentence is said without case endings, in a natural spoken rhythm:

• الممثلة كانت عم تحكي مع الممثل بعد الحلقة

This is one big reason spoken Levantine feels simpler than fully vocalized Standard Arabic in everyday conversation.
