صديقي يفكك الأريكة.

It breaks down like this:

• صديق = friend
• ـي = my

So صديقي means my friend.

A useful comparison:

• صديق = a friend / friend
• صديقي = my friend
• صديقتي = my female friend

Because a noun becomes definite in Arabic not only with الـ, but also through possession.

So:

• صديق = a friend
• الصديق = the friend
• صديقي = my friend

Once you add ـي = my, the noun is already definite, so you do not add الـ.

يفكك is a verb meaning he disassembles, he takes apart, or he is disassembling.

It comes from the root ف ك ك, which has the general idea of loosening, separating, or undoing.

The fully vocalized form is يُفَكِّكُ.

In ordinary Arabic writing, short vowels and the shadda are usually omitted, so you see يفكك instead of يُفَكِّكُ.

Because the verb already includes that information.

In يفكك, the prefix يـ tells you the subject is third person masculine singular: he.

So يفكك by itself can mean:

• he disassembles
• he is disassembling

Arabic often leaves out separate subject pronouns unless they are needed for emphasis or contrast.

It can mean either one.

The Arabic imperfect tense often covers:

• a present action: is disassembling
• a habitual action: disassembles
• sometimes even near-future meaning, depending on context

So صديقي يفكك الأريكة could mean:

• My friend is disassembling the sofa
• My friend disassembles the sofa

In this sentence, the ongoing meaning is disassembling is the most natural.

Both are possible.

• صديقي يفكك الأريكة starts with the subject: My friend is disassembling the sofa
• يفكك صديقي الأريكة starts with the verb: My friend is disassembling the sofa

The difference is mostly one of style or emphasis.

Starting with صديقي makes my friend the topic of the sentence. It is very natural in Arabic. Starting with the verb is also common, especially in more classically verb-first styles.

أريكة means sofa, couch, or settee.

Adding الـ makes it definite:

• أريكة = a sofa
• الأريكة = the sofa

So الأريكة means the sofa.

Also, in pronunciation, the ل of الـ is pronounced clearly here, because the next sound is not a sun letter. So it is pronounced al-arīka(h), not something like a-rīka.

That final ة is called tāʾ marbūṭa.

It is very common on feminine nouns in Arabic. Many nouns ending in ة are grammatically feminine.

For pronunciation:

• in pause, at the end of a sentence, it is usually pronounced like -a or -ah
• when grammatical endings are fully pronounced, it sounds like -t

So:

• in pause: الأريكة ≈ al-arīkah
• with full case ending as an object: الأريكةَ = al-arīkata

Because يفكك is a transitive verb: someone disassembles something.

Here:

• صديقي = the one doing the action
• الأريكة = the thing being acted on

So الأريكة is the direct object.

In fully marked formal Arabic, the direct object would take the accusative ending:

• الأريكةَ

But in normal unvocalized writing, that ending is usually not shown.

A fully vocalized version would be:

صَدِيقِي يُفَكِّكُ الأَرِيكَةَ

That shows:

• صَدِيقِي = my friend
• يُفَكِّكُ = he disassembles / is disassembling
• الأَرِيكَةَ = the sofa as the direct object

In everyday printed Arabic, these short vowels are usually omitted, which is why learners normally see:

صديقي يفكك الأريكة

A careful pronunciation is:

ṣadīqī yufakkiku al-ʾarīkah

If you want a simpler learner-friendly guide, you can think of it roughly as:

sa-DEE-qee yu-FAK-ki-ku al-a-REE-kah

A few notes:

• ص is a heavier, darker s sound than normal English s
• ي in صديقي gives the my ending -ī
• يفكك has a doubled middle consonant in the fully vocalized form يُفَكِّكُ
• the final ة in الأريكة is usually heard as -ah at the end of the sentence
