المفضلة فيها نسخة مكررة.

A natural Egyptian-style pronunciation would be:

el-mofaDDala fiiha noskha mokarrara

A few notes:

• الـ is usually pronounced el- in Egyptian.
• فيها is fiiha.
• نسخة is often pronounced noskha in Egyptian speech, rather than the more MSA-like nuskha.
• مكررة is pronounced mokarrara.
• The letter ض in المفضلة sounds like an emphatic d.

This is a very common question.

المفضلة is grammatically feminine singular, but that does not always mean the meaning is singular in English.

In Arabic, especially in menus, apps, and interface language, a word like المفضلة can be shorthand for a longer phrase such as:

• العناصر المفضلة = favorite items
• الصفحات المفضلة = favorite pages

For non-human plurals, Arabic often uses feminine singular agreement. So even if the hidden noun is plural, the adjective may still appear as المفضلة.

So here, المفضلة can function like a label meaning Favorites.

فيها is made of:

• في = in
• ها = it / her

So literally, فيها means in it.

In this sentence, it works like:

• in it
• or more naturally in English, it has

So:

• المفضلة فيها نسخة مكررة
• literally: Favorites, in it a duplicate copy
• natural English: The Favorites has a duplicate copy in it or There is a duplicate copy in Favorites

This use of في + pronoun is very common in Arabic to express what English often says with has.

Because Arabic often does not use a present-tense verb for to be the way English does.

This is a nominal sentence. In the present tense, Arabic often just puts the parts next to each other and lets the relationship be understood.

Also, Arabic often expresses possession or contents with a structure like:

• X فيه Y = X has Y
  literally: In X there is Y

So here:

• المفضلة فيها نسخة مكررة
• literally: In Favorites there is a duplicate copy

No separate word for is or has is necessary.

This is a topic-comment structure, which is very common in Arabic.

The sentence is organized like this:

• المفضلة = the topic
• فيها نسخة مكررة = what is being said about it

So the feeling is something like:

• As for Favorites, there is a duplicate copy in it

Arabic often puts the topic first, especially when you are talking about a place, folder, section, or item and then describing what is inside it.

It refers back to المفضلة.

So ها means it, referring to the Favorites section/list/folder.

Arabic attached pronouns match the grammatical gender of the noun they refer to. Since المفضلة is being treated as feminine singular, the pronoun is ها.

So:

• فيها = in it
• where it = المفضلة

نسخة مكررة is a noun plus adjective:

• نسخة = copy / version
• مكررة = repeated / duplicated

Together, they mean a duplicate copy.

A key grammar point:

• نسخة is a feminine singular noun
• so the adjective مكررة must also be feminine singular

This is normal adjective agreement in Arabic.

Because it describes نسخة, and نسخة is feminine.

Arabic adjectives agree with the nouns they describe in:

• gender
• number
• definiteness

So:

• نسخة = feminine singular
• مكررة = feminine singular

If the noun were masculine, the adjective would look different.

Because the sentence is talking about an unspecified duplicate copy, not the specific duplicate copy.

So:

• نسخة مكررة = a duplicate copy
• النسخة المكررة = the duplicate copy

The sentence is simply saying that such a copy exists there, so the indefinite form is natural.

It is fully understandable in Egyptian Arabic, but it feels fairly neutral or semi-formal, especially because it sounds like interface or technical language.

That is very common with computer, phone, and app vocabulary. Egyptian speakers often use sentences that are not heavily colloquial in those contexts.

So the sentence is:

• natural enough
• easy for Egyptians to understand
• not strongly slangy or deeply colloquial

In other words, it works well as Egyptian usage, especially in tech/UI language.
