صديقتي بتحب السباحة اكتر من الركض، فعملت اشتراك بالشهر بالنادي.

The base word is صديقة = female friend. When a noun ending in ة takes a suffix, that ة shows up as ت:

• صديقة → صديقتي = my female friend
• سيارة → سيارتي = my car

The suffix -ي means my.

If the friend were male, you would say صديقي.

That is very natural in Levantine. Everyday spoken Arabic often uses topic-first word order:

• صديقتي بتحب... = My friend likes...

It is a bit like saying as for my friend, she likes... in English.
Verb-first order also exists in Arabic, but noun + verb is extremely common in conversation.

In Levantine, بـ on the imperfect verb usually marks the normal present/habitual form.

So:

• بتحب = she likes / she loves

Without بـ, the verb can sound more formal or appear in other grammatical contexts. For a simple everyday statement like this, بتحب is the expected Levantine form.

By itself, بتحب can mean either:

• she likes
• you like (when speaking to one woman)

The subject before it makes it clear. Since the sentence starts with صديقتي, the meaning here is definitely my friend likes.

Both words are verbal nouns used to name activities:

• السباحة = swimming
• الركض = running

In Arabic, it is very common to use الـ with activities when speaking about them in a general sense, especially after verbs like حبّ. So بتحب السباحة is the normal way to say she likes swimming.

اكتر means more, and من means than.

So:

• اكتر من = more than

Here it compares two activities:

• السباحة اكتر من الركض = swimming more than running

In more formal Arabic, you would often see أكثر من, but اكتر من is the normal colloquial form.

It means so, therefore, or then. It links the second part of the sentence to the first as a result.

So the logic is:

• she likes swimming more than running,
• so she got a membership.

In writing, فـ is often attached directly to the next word, as in فعملت.

In Levantine, عملت can be ambiguous by itself. Depending on context, it can mean:

• I did
• you did (to one man)
• she did

Here the previous subject is صديقتي, so the meaning is clearly she did / she made / she got.

This is very common in Arabic: context usually tells you which person is meant.

Yes. It is understandable and natural enough in colloquial speech. Literally it is made/did a subscription, but the real meaning is got a membership or signed up.

Other common ways to express a similar idea are:

• اشتركت بالنادي = she joined the club / signed up at the club
• عملت عضوية بالنادي = she got a membership at the club
• أخذت اشتراك بالنادي = she took out a membership in some varieties

So عملت اشتراك is fine, but it is not the only possible phrasing.

Here بالشهر means by the month or monthly.

So:

• اشتراك بالشهر = a monthly subscription / monthly membership

It describes the type of membership, not something that happens repeatedly.

Compare:

• اشتراك بالشهر = monthly subscription
• كل شهر = every month

You could also hear اشتراك شهري, which means basically the same thing.

بالنادي here means something like at the club, in the club, or more naturally for the club membership.

In Levantine, بـ is very flexible and often covers meanings that English splits into in, at, and sometimes for. With اشتراك, بالنادي is a very natural combination.

• اشتراك بالنادي = club membership / membership at the club

في النادي is also possible, but it sounds more purely locational, while بالنادي fits very naturally with the idea of membership.

It is correct and widely understood, but many speakers also use الجري in everyday speech. Which one sounds more natural can depend on region and speaker.

So both of these would be understood:

• بتحب السباحة اكتر من الركض
• بتحب السباحة اكتر من الجري

Both are fine, but الركض may sound a little more standard or formal to some speakers.
