Learn Hardcore Arabic (Egyptian): صاحبتي وصلت المطار بدري عشان عندها حجز على طيارة الصبح. - My female friend got to the airport early because she has a booking on a morning plane.

صاحبة means female friend (or female companion), and in Egyptian Arabic it is often pronounced more like صاحبة / ṣāḥba or used in the colloquial form صاحبة / صاحبة. When you add -ي, it means my:

صاحبتي = my female friend

This is specifically feminine. A male friend would usually be:

صاحبي = my male friend / my friend (male)

So the sentence is clearly talking about a woman.

Why is the verb وصلت written with a final -ت?

Because the subject is feminine singular.

The verb وصل means arrive. In the past tense:

وصل = he arrived
وصلت = she arrived

Since صاحبتي is feminine, the verb must match it:

صاحبتي وصلت = my female friend arrived

In Egyptian Arabic, this is very common and important: past-tense verbs show gender in the singular.

Why does the sentence start with صاحبتي instead of the verb?

In Arabic, both verb-first and subject-first orders are possible, but in everyday Egyptian Arabic, subject-first is extremely common.

So:

صاحبتي وصلت المطار = My friend arrived at the airport

sounds very natural in conversation.

A more verb-first structure is also possible in Arabic generally, but in Egyptian speech, starting with the subject often feels more straightforward and conversational.
