هل يوجد إنترنت في هذه الغرفة الآن؟

هل is a yes/no question particle in Modern Standard Arabic (MSA). It signals that what follows is a statement being turned into a yes/no question. It doesn’t change word order by itself; it just marks the sentence as interrogative.

يوجد is a verb meaning to exist / to be found (present tense, 3rd person masculine singular). In MSA it’s commonly used to express there is/are:

• يوجد + noun = There is/are + noun It’s often followed by the thing that exists (here: إنترنت), and optionally a location phrase (here: في هذه الغرفة).

Arabic often uses يوجد in a default singular form to mean there exists, regardless of whether the thing is singular, plural, or a mass noun. If the existing thing is clearly plural and you want to match it, Arabic can use توجد (feminine singular) for some plural nouns, but يوجد is extremely common as a general “there is” verb.

Loanwords like إنترنت don’t always have a strongly fixed grammatical gender in everyday use, but they’re very often treated as masculine in MSA by default. In this sentence, it doesn’t visibly affect anything because يوجد is already in the masculine singular form.

Yes, both are common in MSA:

• هل يوجد إنترنت...؟ = “Does internet exist (here)?”
• هل هناك إنترنت...؟ = “Is there internet (there)?” هناك literally means there but in MSA it’s also used like an existential particle meaning there is/are. Both sound natural; هل يوجد is slightly more verb-like/formal, while هل هناك is very common and straightforward.

في هذه الغرفة is a prepositional phrase meaning in this room:

• في = in
• هذه = this (feminine singular)
• الغرفة = the room
  Arabic commonly places location phrases after the thing being discussed (إنترنت) or after the verb phrase. This order is very normal: هل يوجد + thing + location + time.

Because غرفة (room) is grammatically feminine in Arabic. Demonstratives agree with the noun’s gender and number:

• masculine singular: هذا
• feminine singular: هذه So you get هذه الغرفة = this room.

In Arabic, when a noun is modified by a demonstrative (like هذه), the noun is typically definite, and it commonly takes الـ:

• هذه الغرفة (lit. “this the-room”) is just the normal Arabic way to say this room.
  It’s not redundant in Arabic; it’s standard structure.

الآن means now. It commonly appears at the end of the sentence, but it can be moved for emphasis:

• هل يوجد إنترنت في هذه الغرفة الآن؟ (very natural)
• هل يوجد الآن إنترنت في هذه الغرفة؟ (more emphasis on “now”)

In fully vowelled, formal MSA, you could see case endings:

• هل يوجدُ إنترنتٌ في هذهِ الغرفةِ الآنَ؟ (one possible fully-marked style)
  In real-life reading and most speech, case endings are usually omitted, so the unvowelled form you have is the standard way learners encounter it.

A common careful pronunciation is:

• hal yūjad (هل يوجد)
  Notes:
• The long ū in يوجد is like “oo” in food.
• The final د is a clear “d”.
• In connected speech, هل may sound very short: hal / hil depending on speaker, but hal is the usual teaching pronunciation.
