صاحبي قرر ييجي معانا المتحف عشان هو كمان بيحب التاريخ.

Yes—here صاحبي means my friend / my buddy.

• صاحب can mean friend, companion, and in other contexts owner
• the ending -ي means my

So صاحبي literally means my friend.

In Egyptian Arabic, صاحبي is very natural and conversational. A more formal or MSA-style word would be صديقي.

Depending on context, صاحبي can sometimes also mean my boyfriend, but in a sentence like this, my friend is the normal reading.

Because Egyptian Arabic often uses subject + verb word order in everyday speech.

So:

• صاحبي قرر... = My friend decided...

This is very common and natural. Arabic can also put the verb first, but starting with the subject often makes the sentence feel more conversational and easier to follow.

Arabic does not use an infinitive the way English does.

In English, you say:

• decided to come

In Egyptian Arabic, you usually use:

• قرر ييجي

Literally, it is more like he decided he comes / he should come, but the natural meaning is decided to come.

So after verbs like قرر (decided), Egyptian Arabic commonly puts another verb directly after it.

Because after a verb like قرر, Egyptian Arabic uses the bare imperfect form, not the regular bi- present.

• ييجي = come
• بييجي = usually he comes / he is in the habit of coming

So:

• قرر ييجي = he decided to come
• قرر بييجي would sound wrong here

This is a very common pattern in Egyptian:

• عايز أروح = I want to go
• ممكن أجي = I can come
• قرر ييجي = he decided to come

It comes from the verb جه / ييجي, which means to come.

Some useful forms are:

• جه = he came
• ييجي = he comes / he will come / to come, depending on context

In this sentence, after قرر, ييجي has the sense of to come.

معانا means with us.

It is made of:

• مع = with
• -نا = us / our

So:

• معانا = with us

This is a very common spoken form in Egyptian Arabic.

That is a very common question. In Egyptian Arabic, after verbs of motion, the destination is often said without a separate word for to.

So a sentence like this can naturally have:

• ييجي معانا المتحف

with the meaning come with us to the museum.

English requires to, but Egyptian Arabic often does not. This happens a lot in casual speech with places and destinations.

Here عشان means because.

So:

• عشان هو كمان بيحب التاريخ = because he also likes history

In other contexts, عشان can also mean so that or in order to, but here it clearly gives the reason.

هو كمان means he too / he also.

• هو = he
• كمان = also / too / as well

Including هو makes the subject clear and gives a nice natural emphasis:

• because he also likes history

You may sometimes hear كمان without the pronoun in other sentences, but هو كمان is very common and sounds very natural here.

Because the two verbs are talking about different kinds of meaning:

• قرر = a completed action in the past: he decided
• بيحب = an ongoing fact or state: he likes

So the sentence means:

• He made the decision in the past
• and the reason is that he likes history in general

This matches English very closely:

• My friend decided to come... because he also likes history.

In everyday Egyptian Arabic, the normal present tense usually takes بـ.

So:

• بيحب = he likes
• يحب without بـ is not the normal standalone present in colloquial Egyptian

The form without بـ often appears after another verb, in certain structures, or in more formal Arabic. But by itself, for ordinary present meaning, Egyptian usually wants بيحب.

Arabic often uses the definite article with general subjects, fields, and abstract nouns where English does not.

So:

• بيحب التاريخ = he likes history
• بحب الموسيقى = I like music
• بدرس العربي = I study Arabic

So even though English says just history, Arabic naturally says the history.

The article الـ is not always pronounced the same way.

• المتحف is pronounced el-matḥaf
• التاريخ is pronounced et-tārīkh

Why?

• م in المتحف is a moon letter, so the l sound stays: el-
• ت in التاريخ is a sun letter, so the l sound assimilates to the next consonant: et-

So you write الـ in both words, but pronounce them differently.
