الشركة تفعل الاشتراك.

Because شركة is grammatically feminine in Arabic. Nouns ending in ـة are very often feminine, and شركة is one of them.

So with الشركة meaning the company, Arabic uses the feminine singular verb form:

• هي تفعل
• الشركة تفعل

That is why you see تـ at the start of the verb, not يـ.

If the subject were masculine, like الرجل, you would expect يفعل instead.

ال is the Arabic definite article, equivalent to the in English.

So:

• شركة = a company
• الشركة = the company

And:

• اشتراك = a subscription / sign-up / participation
• الاشتراك = the subscription

In this sentence, both nouns are definite, so the sentence is talking about a specific company and a specific subscription.

This is a very common source of confusion in Arabic because normal writing often leaves out short vowels and shadda.

The written form تفعل can represent different vocalizations, including:

• تَفْعَلُ / تَفْعَل = she/it does
• تُفَعِّلُ = she/it activates, enables, causes to function

If the intended meaning is activates the subscription, then the intended verb is likely تُفَعِّلُ from Form II, even though the sentence is written without the marks that would make that obvious.

So the bare spelling تفعل is ambiguous unless context or full vocalization makes it clear.

That depends on which verb meaning is intended.

If it literally means the company does the subscription, it would be pronounced roughly:

• ash-sharikatu tafʿalu al-ishtirāka

If it means the company activates the subscription, it would be:

• ash-sharikatu tufaʿʿilu al-ishtirāka

A few pronunciation notes:

• الشركة is pronounced ash-sharika..., not al-sharika, because ش is a sun letter, so the l sound of ال assimilates.
• الاشتراك keeps the l sound, so it is al-ishtirāk.

In normal pause, final case vowels are often not pronounced, so you may hear:

• ash-sharika tafʿal al-ishtirāk or
• ash-sharika tufaʿʿil al-ishtirāk

Yes. Arabic allows more than one word order.

This sentence is:

• subject + verb + object

So:

• الشركة = subject
• تفعل = verb
• الاشتراك = object

Arabic can also use verb + subject + object, for example:

• تفعل الشركة الاشتراك or, if the intended meaning is activates,
• تُفَعِّلُ الشركةُ الاشتراكَ

Both patterns are possible in MSA. Verb-first order is very common in formal Arabic, but subject-first order is also common and often feels a bit more straightforward to learners.

الاشتراك is the direct object of the verb.

In other words, it is the thing being acted on:

• the company does/activates the subscription

In full grammatical MSA, the direct object takes the accusative case, so fully marked it would be:

• الاشتراكَ

But in normal Arabic writing, the short vowel at the end is usually not written, so you normally just see الاشتراك.

Because most modern Arabic texts do not write short vowels or case endings.

A fully vocalized version would show more information, for example:

• الشركةُ
• تفعلُ or تُفَعِّلُ
• الاشتراكَ

Those endings show grammatical role:

• ـُ often marks the subject
• ـَ often marks the direct object

But in ordinary print, newspapers, websites, and most books, these endings are usually omitted. Learners often have to infer them from grammar and context.

Not especially, if the intended meaning is something like The company activates the subscription.

If تفعل is understood as the basic verb do, then do the subscription sounds unnatural in Arabic, just as it sounds a bit odd in English.

More natural MSA options would be:

• الشركة تُفَعِّلُ الاشتراكَ = The company activates the subscription.
• تقوم الشركة بتفعيل الاشتراك = The company carries out the activation of the subscription.
• تُفَعِّلُ الشركةُ الاشتراكَ = same meaning, with verb-first order

So this sentence is useful for grammar practice, but a native speaker would probably choose a more idiomatic wording in real life.

No. اشتراك can have several related meanings depending on context, such as:

• subscription
• sign-up
• joining
• participation
• sharing

In a business, phone, internet, or service context, اشتراك often means subscription.

So the exact meaning depends on the situation. That is another reason context matters when reading Arabic.
