الصفحة التي أقرأها الآن فيها خبر مهم.

الصفحة means the page, so it is definite. In this sentence, the speaker has a specific page in mind: the page that I am reading now.

In Arabic, a noun followed by a relative pronoun like التي is normally definite. So الصفحة التي... is a natural way to say the page that....

If you said صفحة without الـ, it would mean a page, and the structure would usually be different.

التي means which / that and is the feminine singular relative pronoun.

It matches الصفحة, because:

• صفحة is singular
• صفحة is feminine

So Arabic uses التي to agree with the noun it refers to.

Some matching forms are:

• الذي = masculine singular
• التي = feminine singular
• اللذان / اللتين = dual
• الذين = masculine plural
• اللاتي / اللواتي = feminine plural

Many Arabic nouns are grammatically feminine, and صفحة is one of them. A common sign of feminine nouns is the ـة ending, and صفحة has that ending.

Because it is feminine, anything that agrees with it must also be feminine, such as the relative pronoun التي.

The ها is an object pronoun meaning it, and it refers back to الصفحة.

So:

• أقرأ = I read / I am reading
• أقرأها = I read it / I am reading it

In this relative clause, Arabic normally keeps that pronoun inside the clause when the noun being described is the object of the verb. So literally, the structure is like:

the page that I am reading it now

That sounds wrong in English, but it is normal in Arabic.

In standard Arabic, that would not be correct here.

The verb أقرأ is transitive, so it needs an object: I read what? The object is the page, and Arabic shows that with the resumptive pronoun ها inside the relative clause.

So الصفحة التي أقرأها الآن is the correct MSA form.

الآن means now, and here it functions as an adverb of time.

Its position is flexible, but أقرأها الآن is a very natural word order in Arabic. It keeps the basic idea clear:

• verb: أقرأ
• object: ها
• time: الآن

Other placements are possible in some contexts, but this one is straightforward and idiomatic.

فيها is made of:

• في = in
• ها = it / her

So فيها literally means in it.

Here ها refers back to الصفحة, so فيها خبر مهم literally means in it is important news.

In natural English, you might translate it as:

• It has important news
• There is important news on it
• The page contains an important news item

That is a very common learner question. Arabic often uses في with written content where English prefers on.

So for text, information, or a news item appearing on a page, في الصفحة or فيها is very natural in Arabic.

English and Arabic do not always use the same prepositions. This is one of those places where you should learn the Arabic expression as it is.

This is a very common Arabic pattern:

• a prepositional phrase first: فيها
• then an indefinite noun: خبر
• then its adjective: مهم

So the structure is similar to an existential sentence like there is...

Fully vocalized, it would be:

فيها خبرٌ مهمٌّ

Here, خبرٌ is the postponed subject, and فيها comes first as a fronted prepositional phrase.

So the sense is: There is important news in/on it.

Because مهم is describing خبر, not الصفحة.

And خبر is grammatically masculine singular, so the adjective must also be masculine singular:

• خبر مهم = important news / an important news item

If it were describing a feminine noun, then you would use مهمة.

Also, because خبر is indefinite, the adjective is indefinite too. So not الخبر المهم, but خبر مهم.

Here خبر means something like:

• news
• a news item
• a report
• an article depending on context

It is singular in form, but in English news is often uncountable, so translation may vary.

Also, learners sometimes know خبر as a grammar term meaning predicate in Arabic grammar. That is a different use of the same word. In this sentence, it simply means news.

The sentence can be broken down like this:

• الصفحة = the page
• التي أقرأها الآن = that I am reading now
• فيها خبر مهم = has important news / contains an important news item

So the whole sentence is a nominal sentence whose subject is الصفحة, modified by a relative clause, and whose predicate is فيها خبر مهم.

A very literal gloss would be:

The page that I am reading now, in it is important news.

That literal version is not good English, but it helps show how the Arabic is built.
