يتحقق موظف الاستقبال من بطاقة الغرفة.

Because a very common default word order in Modern Standard Arabic is verb + subject + rest of sentence.

So:

• يتحقق = checks / verifies
• موظف الاستقبال = the receptionist
• من بطاقة الغرفة = the room card

This verb-first order is very normal in MSA. You could also say:

• موظف الاستقبال يتحقق من بطاقة الغرفة

That version is also correct, but it puts more focus on the receptionist as the topic.

Here, يتحقق means checks, verifies, or makes sure.

In this sentence, it does not mean simply achieves or comes true. The meaning depends on the preposition that follows it.

• يتحقق من ... = to check / verify / make sure of something

So in this sentence, يتحقق من بطاقة الغرفة means he checks the room card.

Because the verb in this meaning is used as:

• تحقق من = to check / verify

So the thing being checked comes after من.

This is an important point for English speakers, because in English check usually takes a direct object:

• He checks the card

But in Arabic, with this verb, you normally say:

• يتحقق من البطاقة or يتحقق من بطاقة الغرفة
• literally: he verifies from / of the card
• naturally: he checks the card

So من is required by this verb pattern.

Because this is an iḍāfa construction, often called a genitive construction or noun-noun phrase.

• موظف = employee
• الاستقبال = the reception / front desk

Together:

• موظف الاستقبال = the employee of the reception
• natural English: the receptionist

In an iḍāfa:

• the first noun usually does not take ال
• the second noun can make the whole phrase definite

So even though موظف does not have ال, the whole phrase موظف الاستقبال is definite because الاستقبال is definite.

Yes, it is a very natural expression.

Literally it means:

• reception employee
• or employee of the reception/front desk

In context, that is simply the receptionist.

Arabic often uses descriptive noun phrases like this where English uses a single job title.

For the same reason: this is also an iḍāfa construction.

• بطاقة = card
• الغرفة = the room

Together:

• بطاقة الغرفة = the room’s card / the room card

In iḍāfa:

• the first noun normally does not take ال
• the second noun can be definite

So بطاقة الغرفة is correct, while البطاقة الغرفة would be wrong in standard Arabic.

In context, it usually means the room card or the room key card.

Arabic often leaves that kind of detail to context. In a hotel setting, بطاقة الغرفة would naturally be understood as the card associated with the room, often the access card.

It is in the imperfect form, which often covers:

• present
• ongoing action
• habitual action
• sometimes near future, depending on context

So here it could mean:

• The receptionist checks the room card
• The receptionist is checking the room card

The exact English translation depends on context.

In normal Arabic writing, short vowels and most case endings are usually not written. But grammatically, they are there.

With full case endings, the sentence would be:

• يَتَحَقَّقُ مُوَظَّفُ الاسْتِقْبالِ مِنْ بِطاقَةِ الغُرْفَةِ

The endings are:

• موظفُ → nominative, because it is the subject
• الاستقبالِ → genitive, because it is the second part of an iḍāfa
• بطاقةِ → genitive, because it comes after من
• الغرفةِ → genitive, because it is the second part of an iḍāfa

So this sentence contains several genitive relationships.

You would change the subject and the verb to feminine singular:

• تتحقق موظفة الاستقبال من بطاقة الغرفة

Breakdown:

• تتحقق = she checks / verifies
• موظفة الاستقبال = the female receptionist

So Arabic marks gender in both the verb and the noun.

A helpful pronunciation is:

• yataḥaqqaqu

A few notes:

• ḥ is a strong breathy h sound, from ح
• qq shows a doubled consonant, because ق has a shadda
• q is the sound of ق, pronounced farther back than English k

A fuller pronunciation of the sentence is roughly:

• yataḥaqqaqu muwaẓẓafu l-istiqbāli min biṭāqati l-ghurfati

If you are reading without case endings in normal speech, you will often hear something closer to:

• yataḥaqqaq muwaẓẓaf al-istiqbāl min biṭāqat al-ghurfa

Yes. The root is ح ق ق.

This root is connected with ideas like:

• truth
• reality
• verification
• certainty

That is why words from this root often relate to things being true, real, or confirmed.

So يتحقق من has the sense of making sure something is valid or correct, which is why it works well for checking or verifying a card.
