صاحبتي ساعدت اختها تلاقي المقاس في المحل.

In Egyptian Arabic, صاحبتي usually means my female friend.

It can sometimes mean my girlfriend, but that depends entirely on context. On its own, many learners should first understand it as:

• صاحب = friend / companion
• صاحبتي = my female friend

The masculine version is صاحبي = my male friend / my friend.

So in this sentence, صاحبتي most naturally means my female friend.

The -ت marks the verb as past tense, feminine singular.

So:

• ساعد = he helped
• ساعدت = she helped

Since صاحبتي is feminine, the verb has to match it:

• صاحبتي ساعدت = my friend helped

This is very common in Arabic: past-tense verbs agree with the subject in gender and number.

Both spellings point to the same word: her sister.

More formally, you may see:

• أختها

In casual Egyptian writing, especially online or in informal texting, the hamza is often omitted:

• اختها

So:

• أخت / اخت = sister
• -ها = her

Together:

• أختها / اختها = her sister

This kind of relaxed spelling is very common in dialect writing.

The suffix -ها means her.

So:

• أخت = sister
• أختها = her sister

Arabic often attaches pronouns directly to nouns instead of using a separate word like English does.

A few similar examples:

• أخوها = her brother
• أمها = her mother
• كتابها = her book

So here, اختها is literally her sister.

Egyptian Arabic does not use an infinitive the way English does.

In English, you say:

• helped her sister find the size

In Egyptian Arabic, after a verb like ساعد (help), the next verb is often just a normal present-tense verb:

• ساعدت اختها تلاقي...
• literally: she helped her sister [she finds]...
• naturally: she helped her sister find...

So تلاقي is functioning where English would use to find.

This is very normal in spoken Egyptian Arabic.

Because the person doing the finding is اختها (her sister), and that noun is feminine singular.

So the verb is in the form for she finds:

• يلاقي = he finds
• تلاقي = she finds

Even though the main verb is in the past (ساعدت), the second verb stays in this present form because it expresses the action being helped.

So:

• ساعدت اختها تلاقي المقاس = She helped her sister find the size

The agreement of تلاقي is with اختها, not with صاحبتي.

Because بـ in Egyptian often marks the regular present or habitual sense, like she finds / she usually finds.

For example:

• بتلاقي = she finds / she usually finds

But after verbs like ساعد (helped), the following verb is normally used without بـ:

• ساعدتها تلاقي... = I helped her find...

So تلاقي here is the correct pattern after ساعدت.

المقاس means the size.

In a shopping context, it usually means:

• clothing size
• shoe size
• the right fit

So in this sentence, it most likely means something like:

• the right size
• her size
• the correct size

Even though the literal word is the size, English often translates it more naturally depending on context.

في المحل means in the store / at the shop.

Breakdown:

• في = in / at
• المحل = the shop / the store

In Egyptian Arabic, المحل is a very common word for a shop or store.

So:

• في المحل = in the store
• or more naturally in English: at the store

A simple learner-friendly pronunciation would be:

saḥbti sāʕdet okhtha telāʔi l-meʔās fil-maḥall

A few notes:

• ص is a heavy s
• ح is a strong breathy h
• ع in ساعدت is the Arabic letter ʕayn, a sound English doesn’t really have
• ق in Egyptian Arabic is often pronounced like a glottal stop ʔ, so المقاس sounds like el-meʔās
• في المحل is often heard smoothly as fil-maḥall

You do not need perfect pronunciation right away; the important thing is to notice the overall rhythm of the sentence.

Yes, this word order is very natural.

The sentence is structured like this:

• صاحبتي = subject
• ساعدت = main verb
• اختها = object of helped
• تلاقي المقاس = the action her sister was helped to do
• في المحل = location

So the whole thing is essentially:

• My friend helped her sister find the size in the store

This is a very common Egyptian pattern: subject + past verb + object + second verb + rest of sentence

Yes. In a more formal variety, you would likely see different vocabulary and structure, such as:

• ساعدت صديقتها أختها في العثور على المقاس في المتجر
• or something similar depending on the exact intended meaning

But the given sentence is clearly Egyptian colloquial, and that is why you see things like:

• صاحبتي instead of a more formal word like صديقتي
• تلاقي instead of a formal infinitive-style structure
• المحل as a common everyday word for shop/store

So this sentence is very natural for spoken Egyptian Arabic.
