زميل بالشغل ساعد زميلة جديدة لما ما عرفت تستعمل الموقع.

Because Levantine often uses subject–verb–object order in everyday speech, especially when introducing a person or telling a simple story.

So:

• زميل بالشغل ساعد... = A coworker helped...

You could also say:

• ساعد زميل بالشغل زميلة جديدة...

That is also grammatical, but the original version feels very natural in spoken Levantine.

زميل means colleague / coworker.

بالشغل literally means something like at work / in work, from:

• بـ = in / at / with
• الشغل = the work / work

Together, زميل بالشغل is a very natural Levantine way to say coworker or a colleague from work.

In speech, بالشغل is often pronounced something like bish-shughl because ش is a sun letter, so the ل of ال is not pronounced.

Arabic does not have an indefinite article like English a / an.

So:

• زميل = a coworker
• زميلة جديدة = a new female coworker

If the noun has الـ, it becomes definite:

• الزميل = the coworker
• الزميلة الجديدة = the new female coworker

Because the subject is زميل, which is masculine singular.

So the past verb matches that:

• زميل ... ساعد = a male coworker helped

If the subject were feminine, you would say:

• زميلة بالشغل ساعدت... = a female coworker helped...

In Arabic, adjectives normally come after the noun they describe.

So:

• زميلة جديدة = a new female coworker

Also, the adjective has to agree with the noun in:

• gender
• number
• definiteness

Here both are:

• feminine singular
• indefinite

So جديدة matches زميلة.

It refers to زميلة جديدة, the new female coworker.

So the meaning is:

• A coworker helped a new female coworker when she didn’t know how to use the site.

One thing that can confuse learners is that عرفت in Levantine can be ambiguous by itself. Depending on context, it can mean I knew, you knew, or she knew. Here, context makes it clear that it means she knew / she managed, referring to the new coworker.

Here لما means when.

It introduces the time clause:

• لما ما عرفت تستعمل الموقع = when she didn’t know how to use the website

In Levantine, لما is very common for past-time when. It often feels very natural in storytelling or narration.

In Levantine, ما is the normal way to negate many verbs, especially past-tense verbs.

So:

• عرفت = she knew / managed
• ما عرفت = she didn’t know / didn’t manage

Using مو here would not be the normal choice. مو is more commonly used with nouns, adjectives, and some non-verbal expressions.

It can suggest both, and that is very common with عرف in Levantine.

عرف + imperfect verb often means:

• to know how to do something
• and by extension sometimes to be able to manage doing it

So:

• ما عرفت تستعمل الموقع

can be understood as:

• she didn’t know how to use the website
• or she couldn’t manage to use the website

Usually the context tells you which English translation sounds best.

Because after عرف meaning know how, the next verb is usually in the bare imperfect, without بـ.

Compare:

• بعرف اسوق = I know how to drive
• not usually بعرف بسوق for that meaning

So:

• عرفت تستعمل = she knew how to use
• ما عرفت تستعمل = she didn’t know how to use

The بـ prefix is often used for ordinary present/habitual actions, but not usually after verbs like عرف in this structure.

Yes. Both are possible.

• استعمل / يستعمل is very common in Levantine speech for use
• استخدم / يستخدم is also understood and used, sometimes sounding a bit more formal depending on the speaker or region

So this would also work:

• زميل بالشغل ساعد زميلة جديدة لما ما عرفت تستخدم الموقع

Same basic meaning.

Because it probably refers to a specific website or platform that both speaker and listener can identify.

So:

• الموقع = the website / the site

In real-life Arabic, speakers often use the definite form when the thing is understood from context, even if English might sometimes say a site in a similar situation.

Both can exist in Arabic, but زميل بالشغل is a very common Levantine expression meaning coworker.

The preposition بـ here is part of a natural collocation, not just a literal location word.

Very roughly:

• زميل بالشغل = a coworker / a colleague from work
• في الشغل often means at work in a more literal sense
• من الشغل often means from work

So in this sentence, بالشغل sounds especially natural.
