انقطاع الكهرباء الآن.

Because Arabic often allows a verbless sentence, especially in headlines, notices, alerts, and short announcements.

So انقطاع الكهرباء الآن is a very compact way to say something like:

• There is a power outage now
• Power outage now

Arabic does not always need a verb like is or there is in this kind of context.

A fuller version could be:

• هناك انقطاع في الكهرباء الآن
• يوجد انقطاع للكهرباء الآن

But the shorter version sounds very natural in notices and news-style wording.

Yes. انقطاع الكهرباء is an iḍāfa (construct phrase).

Breakdown:

• انقطاع = interruption / outage / cutting off
• الكهرباء = the electricity

Together, they mean something like:

• interruption of the electricity
• more naturally, power outage

In an iḍāfa:

• the first noun (انقطاع) does not take ال
• the second noun (الكهرباء) is put after it
• the second noun is grammatically in the genitive

So this is a very common Arabic way to express what English often says with of.

Because الكهرباء here is treated as a definite noun: the electricity.

In Arabic, many abstract or general concepts are commonly used with الـ, especially when referring to something understood in context. In this phrase, Arabic naturally says the electricity, even though English may simply say power.

Also, in an iḍāfa, if the second noun is definite, the whole phrase becomes definite in meaning. So:

• انقطاع كهرباء would sound less standard here
• انقطاع الكهرباء is the normal, idiomatic expression

انقطاع is a verbal noun (a maṣdar) from a verb related to being cut off, interrupted, or discontinued.

In this sentence, it means:

• interruption
• cutoff
• outage

So Arabic uses a noun, not a finite verb, to express the event. This is very common in formal Arabic and in short notices.

الآن means now and functions as an adverb of time.

It tells you when the outage is happening:

• انقطاع الكهرباء الآن = power outage now

It can often move around depending on emphasis, but the meaning stays similar. For example:

• انقطاع الكهرباء الآن = straightforward
• الآن انقطاع الكهرباء = more marked or emphatic, and less neutral in many contexts

So in your sentence, الآن simply adds the time reference.

This is a good question because it can look strange to English speakers.

الآن is basically a fixed word meaning now. Even though it begins with الـ, learners should usually treat it as a complete vocabulary item rather than trying to interpret it literally piece by piece.

So the safest approach is:

• learn الآن as a whole word
• use it to mean now

A careful pronunciation is:

inqiṭāʿ al-kahrabāʾ al-ʾān

A few useful notes:

• انقطاع = in-qi-ṭāʿ
• الكهرباء = al-kahrabāʾ
• الآن = al-ʾān

Points that may help:

• ق in انقطاع is a deep q sound, not an English k
• ط is an emphatic ṭ
• the final ء in الكهرباء is a glottal stop
• ال is pronounced clearly in الكهرباء because ك is a moon letter

In fully vowelled formal Arabic, you could read it as:

انقطاعُ الكهرباءِ الآنَ

Here is why:

• انقطاعُ: nominative, if treated as the main noun of the sentence
• الكهرباءِ: genitive because it is the second part of the iḍāfa
• الآنَ: an adverb of time, commonly pronounced with fatḥa

In normal everyday writing, these endings are usually not written, and in pause they are often not pronounced fully.

It can function as a complete message, especially in contexts like:

• news headlines
• phone alerts
• signs
• emergency announcements
• captions

Arabic often uses short noun-based expressions where English might prefer a full sentence. So although it may look like just a phrase to an English speaker, in real usage it can absolutely stand on its own as a complete notice.

Yes. Some fuller alternatives are:

• هناك انقطاع في الكهرباء الآن
• يوجد انقطاع في الكهرباء الآن
• انقطعت الكهرباء الآن

These differ slightly in style:

• هناك / يوجد... = more explicit about existence
• انقطعت الكهرباء الآن = uses a verb, more like the power has gone out now
• انقطاع الكهرباء الآن = shortest, most notice-like, most headline-like

Arabic often prefers a compact noun-to-noun structure where English might use of or another linking word.

So:

• انقطاع الكهرباء = the outage of the electricity / power outage

A version with في is possible in some contexts, such as:

• انقطاع في الكهرباء

But that often feels less compact and less idiomatic here. The iḍāfa version is the most natural short expression.

Yes. A very common alternative is:

• انقطاع التيار الكهربائي

This is a bit more technical or formal. Literally it refers to the interruption of the electric current.

Comparison:

• انقطاع الكهرباء = common, everyday, clear
• انقطاع التيار الكهربائي = more formal, often heard in news and official language

Both are correct, and both are useful to know.
