الفني يوصل الكابل بالموجه.

Here الفني means the technician.

It is originally related to the adjective فنيّ meaning technical, but in context Arabic often uses this kind of word as a noun meaning a technical specialist / technician. Since the sentence is about a cable and a router, the technician is the natural meaning.

It is:

• singular
• masculine
• definite because of الـ

الـ is the Arabic definite article, like the in English.

So:

• الفني = the technician
• الكابل = the cable
• الموجه = the router

The sentence is talking about specific, identifiable things, not just any technician or any cable.

In this sentence, it is usually understood as يُوَصِّلُ.

That means he connects or he is connecting.

A few useful points:

• it is present/imperfect tense
• it is 3rd person masculine singular
• Arabic normally leaves out short vowels and shadda in everyday writing, so يوصل can look ambiguous until context makes the meaning clear

So the learner should understand it here as connects.

No. They are related, but they are not the same form.

• يصل often means he arrives / he reaches
• يُوَصِّلُ here means he connects

This is an important pattern in Arabic: a small change in the verb form can change the meaning a lot.

So in this sentence, the intended meaning is clearly connects, not arrives.

Because Arabic and English do not always use the same preposition with the same verb.

With a verb like connect, Arabic commonly uses بـ for the thing something is connected to.

So:

• يوصل الكابل بالموجه = connects the cable to the router

Even though بـ often means with / by / in, here the best English translation is usually to.

Here الموجه means the router.

In fully marked Arabic, it would typically be read as الموجِّه. In technical Arabic, this is a standard word for router.

It comes from a word related to directing / routing, so the basic idea is something like the directing device.

The structure is:

• الفني = subject
• يوصل = verb
• الكابل = direct object
• بالموجه = prepositional phrase

So the pattern is:

subject + verb + object + prepositional phrase

That is a perfectly normal Arabic sentence pattern.

Yes, that is also possible.

Arabic allows both:

• الفني يوصل الكابل بالموجه
• يوصل الفني الكابل بالموجه

The first version starts with the subject and gives a little more prominence to the technician.

The second version starts with the verb and can sound more like a neutral action statement.

Both are grammatical.

A fully vocalized version would be:

الفنّيُّ يُوَصِّلُ الكابلَ بالموجِّهِ

This shows the grammar more clearly:

• الفنّيُّ = nominative subject
• الكابلَ = accusative direct object
• بالموجِّهِ = genitive after the preposition بـ

In normal modern writing, these short vowels are usually omitted.

It is a modern technical borrowing, basically corresponding to English cable.

This is very common in Arabic technical vocabulary. Learners will often see borrowed words alongside native Arabic words in technology contexts.

So الكابل is a normal and natural word to use here.
