ترسل خدمة العملاء رسالة.

Because this is a very common Arabic word order: verb + subject + object.

So:

• ترسل = sends / is sending
• خدمة العملاء = customer service
• رسالة = a message

Arabic can also use subject + verb + object, but starting with the verb is extremely common in Modern Standard Arabic.

The subject is خدمة العملاء, and the head noun is خدمة meaning service.

خدمة is a grammatically feminine noun, which is easy to spot because it ends in ة (taa marbuuTa).

So the verb must match it in gender:

• ترسل = she/it sends or you send depending on context
• here it means it sends, referring to خدمة

This is grammatical gender, not biological gender. Arabic often treats non-human or abstract nouns as masculine or feminine based on grammar.

By itself, ترسل can mean:

• she sends
• it sends
• you (masculine singular) send

The rest of the sentence removes the ambiguity. After the verb, we get the explicit subject خدمة العملاء, so here ترسل clearly means customer service sends.

It is an iDaafa construction, often called a genitive construction or noun annexation.

Literally, it is:

• خدمة = service
• العملاء = the customers / the clients

So word-for-word it is service of the customers, but in natural English this is customer service.

In Arabic, this structure is very common for phrases like:

• كتاب الطالب = the student’s book
• مدير الشركة = the company’s manager
• خدمة العملاء = customer service

Because in an iDaafa construction, the first noun usually does not take ال.

So you say:

• خدمة العملاء = the customer service / customer service

not:

• الخدمة العملاء ❌

The definiteness of the whole phrase comes from the second noun:

• العملاء is definite because it has ال
• therefore خدمة العملاء as a whole is also definite

This is a very important Arabic pattern.

Because it means a message, not the message.

• رسالة = a message
• الرسالة = the message

Since there is no ال on رسالة, it is indefinite.

So the sentence means:

• Customer service sends a message

If you wanted the message, you would say:

• ترسل خدمة العملاء الرسالة.

In fully vocalized MSA, the sentence would be:

تُرسِلُ خِدمةُ العُمَلاءِ رسالةً

The endings are:

• تُرسِلُ → verb in the indicative, ending in ـُ
• خِدمةُ → subject, so nominative
• العُمَلاءِ → second part of an iDaafa, so genitive
• رسالةً → direct object, so accusative

In normal Arabic writing, these short vowel endings are usually omitted, so learners often see:

ترسل خدمة العملاء رسالة

without the final vowel marks.

Because العملاء means the customers or the clients.

The singular is:

• عميل = customer / client

The plural is:

• عملاء = customers / clients

So خدمة العملاء literally means service of the customers/clients, which is the standard Arabic way to say customer service.

Yes. That is also grammatical.

Compare:

• ترسل خدمة العملاء رسالة.
• خدمة العملاء ترسل رسالة.

Both can mean Customer service sends a message.

The difference is mainly one of style or emphasis:

• ترسل خدمة العملاء رسالة begins with the action
• خدمة العملاء ترسل رسالة begins with the subject

In MSA, both verb-initial and subject-initial sentences are common.

Not exactly. In Arabic, the so-called present form can cover both:

• sends
• is sending

So ترسل خدمة العملاء رسالة can mean:

• Customer service sends a message
• Customer service is sending a message

Context tells you which is more natural.

A careful MSA pronunciation with case endings is approximately:

tursilu khidmatu al-ʿumalāʾi risālatan

A few notes:

• ترسل = tursilu
• خدمة = khidmah / khidmatu depending on whether you pronounce the ending
• العملاء = al-ʿumalāʾ
• رسالة = risālah / risālatan

In everyday reading, many speakers pause and do not pronounce the full case endings, but learners should still understand the full form.

Yes. In Arabic, when the subject follows the verb, the verb is often singular even if the subject is plural.

In this sentence, the subject is singular anyway, so that issue does not change anything:

• خدمة is singular
• so ترسل is singular feminine

But this is a useful rule to know for later Arabic study.

The direct object is رسالة.

It is the thing being sent.

So the sentence breaks down like this:

• ترسل = sends
• خدمة العملاء = customer service
• رسالة = a message

That makes رسالة the object of the verb ترسل.
