سلة المهملات فيها نسخة مكررة.

It literally means the basket of waste/thrown-away things.

• سلة = basket
• المهملات = waste, discarded things, trash

Together, سلة المهملات is the standard way to say trash can / recycle bin / wastebasket in formal Arabic-style wording. In everyday Egyptian speech, people might also say something more colloquial like سلة الزبالة depending on context.

This is an idafa construction (a noun + another noun linked as X of Y), so there is no separate word for of.

Because فيها means in it.

• في = in
• ها = it / her

So:

• في = in
• فيها = in it

In this sentence, فيها نسخة مكررة means something like there is a duplicate copy in it or more literally in it, there is a duplicate copy.

The ها refers back to سلة المهملات, which is grammatically feminine, so ها is the correct pronoun.

This is very common in Arabic.

Arabic often uses a structure like in it / in there to express the idea of there is in a place.

So:

• سلة المهملات فيها نسخة مكررة literally: The trash bin, in it is a duplicate copy
• natural English: There is a duplicate copy in the trash bin

This kind of wording is extremely normal. Arabic does not always need a separate verb like English there is.

Because نسخة is simply a feminine noun in Arabic.

A big clue is the ending ـة (taa marbuuTa), which often marks feminine nouns.

So:

• نسخة = copy
• it is grammatically feminine

Because it is feminine, any adjective describing it must also be feminine.

That is why the sentence has:

• نسخة مكررة not
• نسخة مكرر

Because مكررة is the feminine form of the adjective, and it has to match نسخة.

Arabic adjectives agree with the noun they describe in gender (and usually also in definiteness and number).

• مكرر = repeated / duplicated (masculine)
• مكررة = repeated / duplicated (feminine)

Since نسخة is feminine, the correct form is:

• نسخة مكررة = a duplicate copy

Because the phrase is indefinite: a duplicate copy, not the duplicate copy.

Compare:

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

In Arabic, adjectives usually match the noun in definiteness too:

• indefinite noun → indefinite adjective
• definite noun → definite adjective

So نسخة مكررة is perfectly matched.

It sounds understandable in Egyptian Arabic, but parts of it are more on the formal/neutral side.

In particular:

• سلة المهملات feels fairly standard/formal
• فيها is completely normal in Egyptian
• نسخة مكررة is also natural and understandable

A very everyday Egyptian version might use different vocabulary depending on the situation, but this sentence itself is not strange. It sounds like something you might see in software, interface text, or semi-formal speech.

A rough Egyptian-style pronunciation could be:

sillit il-mohmalāt fīha noskha mokarrara

A few notes:

• سلة is often pronounced something like silla or sillit depending on pause and connected speech
• الـ often becomes il- in Egyptian pronunciation
• نسخة is often noskha
• مكررة may sound like mokarrara

You do not need to pronounce it exactly like formal written Arabic for it to sound natural in Egyptian.

Arabic is flexible with word order, especially in sentences like this.

This sentence starts with the location/topic:

• سلة المهملات فيها نسخة مكررة literally: The trash bin — in it there is a duplicate copy

This puts سلة المهملات first as the topic.

You could also express the idea in a different order, such as a structure closer to In the trash bin there is a duplicate copy. But the given wording is very natural as a topic-comment sentence.

Sometimes yes, depending on how literal you want to be, but the best natural translation here is usually:

• There is a duplicate copy in it or
• It contains a duplicate copy

Arabic فيه / فيها often overlaps with English ideas like:

• there is
• there are
• in it
• it has

The exact English translation depends on what sounds most natural in context.

A simple way to understand it is:

• سلة المهملات = the topic (the trash bin)
• فيها نسخة مكررة = the comment about it (there is a duplicate copy in it)

Inside the second part:

• فيها = in it
• نسخة = copy
• مكررة = duplicated / repeated

So the sentence is built like:

[Topic] + [what is in it]

This is a very useful Arabic pattern to learn.

Yes, that would also be understandable.

That version means more directly:

• In the trash bin, there is a duplicate copy

The difference is mostly about focus and phrasing:

• سلة المهملات فيها نسخة مكررة = The trash bin has / contains a duplicate copy
• في سلة المهملات نسخة مكررة = In the trash bin there is a duplicate copy

Both are possible. The original sentence sounds very natural when the trash bin is the topic.

It can mean both, depending on context.

In many contexts:

• مكرر / مكررة = repeated
• but in computer or file contexts, it often means duplicate

So here نسخة مكررة is best understood as:

• a duplicate copy or simply
• a duplicate

This is especially natural if the sentence appears in a digital or technical context.
