حجزت غرفة مفردة بالفندق.

حجزت means I booked or I reserved.

It is the past tense form of the verb حجز = to book / to reserve.
The ending -ت shows that the subject is I.

So:

• حجز = he booked
• حجزت = I booked

In Levantine speech, the exact pronunciation can vary a bit by region, but the meaning stays the same.

In Arabic, the verb often already tells you who the subject is.
Here, the ending in حجزت already means I, so أنا is not necessary.

So both are possible:

• حجزت غرفة مفردة بالفندق = I booked a single room at the hotel
• أنا حجزت غرفة مفردة بالفندق = I booked a single room at the hotel

Using أنا usually adds emphasis, like I booked it.

Because غرفة is a feminine singular noun, the adjective has to match it.

Arabic adjectives usually agree with the noun in:

• gender
• number
• definiteness

Here:

• غرفة = room, feminine singular
• مفردة = single, feminine singular

So مفردة matches غرفة correctly.

If the noun were masculine, the adjective would usually be masculine too.

Here مفردة means single, as in a single room for one person.

Literally, the word can also mean something like individual or separate, depending on context. But in hotel language, it means a single room.

A learner should also know that in everyday Levantine, many speakers may say سنغل instead, especially in travel or hotel contexts. So you may hear:

• غرفة مفردة = more formal / standard
• غرفة سنغل = very common in everyday speech

بالفندق means at the hotel or in the hotel, depending on context.

It is made of:

• بـ = in / at / with
• الفندق = the hotel

So:

• بـ + الفندق → بالفندق

In this sentence, it tells you the location of the room reservation: the room is at/in the hotel.

Arabic does not have a separate word for a/an.

Instead:

• a noun without ال is usually indefinite
• a noun with ال is usually definite

So:

• غرفة = a room
• الغرفة = the room

That is why غرفة مفردة naturally means a single room.

It is understandable, but it sounds a bit formal or close to Standard Arabic.

A more everyday Levantine version might be something like:

• حجزت غرفة سنغل بالفندق
• حجزت أوضة سنغل بالفندق in dialects that use أوضة for room

So the original sentence is good and clear, but native speakers in casual conversation may choose more colloquial vocabulary.

A rough Levantine-style pronunciation could be:

ḥajazt ghirfe mfarde bil-funduʔ

But pronunciation varies by country and city, so you may hear small differences.

A few common things to notice:

• غرفة is often pronounced more like ghirfe
• بالفندق may sound like bil-funduʔ or something close to that
• short vowels are often reduced in everyday speech

So the written sentence may look somewhat formal, while the spoken pronunciation sounds more distinctly Levantine.

Yes. Arabic allows some flexibility in word order.

The original sentence starts with the verb:

• حجزت غرفة مفردة بالفندق

You could also say:

• أنا حجزت غرفة مفردة بالفندق

Both mean the same thing. Starting with أنا can make the subject more explicit or slightly more emphatic.

The verb-first version is very normal in Arabic.

Because they are doing different jobs in the sentence.

• غرفة is the thing being booked, and it is indefinite: a single room
• الفندق refers to a specific hotel in the situation: the hotel

So:

• غرفة مفردة = a single room
• بالفندق = at the hotel

This mix of indefinite and definite nouns is completely normal in Arabic.
