الإطلالة مذهلة.

In Arabic, present-tense sentences like this usually do not use a separate word for is.

So:

• الإطلالة مذهلة = The view is amazing

This is called a nominal sentence in Arabic.
The structure is:

• الإطلالة = the subject
• مذهلة = the predicate / description

If you wanted to say was or will be, then Arabic would usually add a verb, but in the present tense it is normally omitted.

Because مذهلة here is not being used as an attributive adjective inside a noun phrase like the amazing view. It is the predicate of the sentence: The view is amazing.

Compare:

• الإطلالة مذهلة = The view is amazing
• الإطلالة المذهلة = the amazing view

This is an important difference in Arabic:

• noun + indefinite adjective/predicate often gives a full sentence
• noun + definite adjective gives a noun phrase

So in your sentence, مذهلة is indefinite because it is the statement being made about الإطلالة.

Because إطلالة is a feminine noun, and Arabic adjectives must agree with the noun they describe or refer to in:

• gender
• number
• definiteness (when used attributively)

Here:

• إطلالة is feminine
• so the predicate adjective is also feminine: مذهلة

That is why you see the ـة ending on both words.

The fully vowelled form is:

• الإِطْلالَةُ مُذْهِلَةٌ

In normal everyday writing, these short vowels are usually omitted, so you will most often see:

• الإطلالة مذهلة

If you are studying grammar, the endings are useful:

• الإطلالةُ = subject, typically with ـُ
• مذهلةٌ = predicate, typically with ـٌ

A careful pronunciation is approximately:

• al-iṭlālah

A few notes:

• الـ = al-
• ط is an emphatic t
• لا gives a long ā
• the final ة in pausal pronunciation is usually like -ah

So in normal citation-style pronunciation, it sounds like:

• al-iṭ-laa-lah

If you pronounce full case endings in formal recitation, it would be:

• al-iṭlālatu

إطلالة can mean things like:

• view
• outlook
• vista
• sometimes appearance or look, depending on context

In a sentence like الإطلالة مذهلة, it often means the view or the outlook, especially from a window, balcony, hotel, or building.

So the exact English translation depends on context, even if the general meaning is already clear.

It is a complete sentence.

Specifically, it is a nominal sentence:

• الإطلالة = the topic / subject
• مذهلة = what is being said about it

So this is not just a phrase like the amazing view.
It means The view is amazing.

If you wanted only the phrase the amazing view, you would say:

• الإطلالة المذهلة

مذهلة comes from the root:

• ذ ه ل

This root has to do with being stunned, distracted, or overwhelmed.

The adjective مذهل means:

• amazing
• astonishing
• stunning

And the feminine form is:

• مذهلة

So:

• مذهل = amazing/stunning for a masculine noun
• مذهلة = amazing/stunning for a feminine noun

Yes. If the noun were masculine, you would normally use مذهل.

For example:

• المنظر مذهل = The منظر / scene is amazing
• الإطلالة مذهلة = The view is amazing

So the adjective changes to match the gender of the noun.

You can think of it as both, depending on what level you are studying.

It is:

• an adjective by form and meaning
• a predicate by function in this sentence

So grammatically in the sentence, it is the predicate describing the subject.
But it is still an adjective word.

This is very common in Arabic.

This order is the normal and easiest one for a nominal sentence:

• subject first
• description second

So:

• الإطلالة مذهلة = The view is amazing

You may sometimes see other word orders in Arabic for emphasis or style, but this order is the most straightforward for learners.

Usually, no.

In most modern spoken usage, and even in much written MSA reading outside very formal contexts, learners and native speakers often say:

• الإطلالة مذهلة

without fully pronouncing:

• الإطلالةُ مذهلةٌ

The case endings are important for:

• formal grammar study
• careful reading
• Qur'anic or highly formal recitation
• some news or ceremonial speech styles

But in ordinary practice, many people do not fully pronounce them.

Yes, potentially. إطلالة can sometimes refer to an appearance, look, or public appearance, depending on context.

So the sentence could mean:

• The view is amazing
• The appearance is amazing

But in many everyday contexts, especially with places, hotels, apartments, balconies, or scenery, الإطلالة most naturally means the view.

So context decides the best translation.
