الكسر في الشاشة صغير.

A natural Egyptian-style pronunciation would be:

el-kasr fi sh-shāsha sughayyar

You may also hear fe instead of fi in fast speech.

A few pronunciation notes:

• الكسر → el-kasr
• الشاشة → esh-shāsha / sh-shāsha
  • The ل in الـ is not clearly pronounced here because ش is a sun letter, so the sound assimilates.
• صغير in Egyptian is often said more like sughayyar than the more formal ṣaghīr

So the whole sentence sounds more Egyptian when read aloud, even if the spelling looks close to Standard Arabic.

In Arabic, the present tense often does not use a separate word for is / am / are.

So:

• الكسر في الشاشة صغير = The crack in the screen is small

This is called a nominal sentence.

If you wanted the past, then Arabic would use a verb, for example:

• كان الكسر في الشاشة صغير = The crack in the screen was small

So in the present tense, leaving out is is completely normal.

Because صغير describes الكسر, not الشاشة.

Here is the structure:

• الكسر = the crack / the break
• في الشاشة = in the screen
• صغير = small

The word being described is الكسر, and كسر is masculine, so the adjective is masculine too:

• كسر صغير = a small crack

Even though الشاشة is feminine, it is only part of the prepositional phrase في الشاشة and is not the noun that صغير agrees with.

Compare:

• الشاشة صغيرة = The screen is small
  Here the adjective is feminine because الشاشة is feminine.

Literally, في الشاشة means in the screen.

In English, we might naturally say in the screen or on the screen depending on the situation. Arabic often uses في in places where English might use either in or on.

So for damage like a crack, في الشاشة is natural Arabic.

A helpful way to think of it is:

• في often covers the general idea of being within / in / on depending on context.

Because Arabic often puts the description/predicate after the noun and any attached phrases.

Here the sentence works like this:

• الكسر = the topic / subject
• في الشاشة = extra information about where it is
• صغير = the predicate, giving the main description

So the order is very natural:

• الكسر في الشاشة صغير

English also puts small near the end in The crack in the screen is small, so the idea is not too far from English, even though Arabic has no written is here.

Because الكسر and الشاشة are definite nouns:

• الكسر = the crack
• الشاشة = the screen

But صغير here is not an adjective inside a noun phrase like the small crack. It is the predicate of the sentence, so it normally stays indefinite.

Compare these two:

• الكسر صغير = The crack is small
• الكسر الصغير = the small crack

In the second one, الصغير is directly attached to the noun, so it also takes الـ.

Yes, that is a good question. الكسر comes from the root ك-س-ر, which has the basic idea of breaking.

Depending on context, كسر can mean things like:

• breaking
• breakage
• a break
• a crack
• a fraction

So context is very important.

In this sentence, because we have الشاشة, the meaning is clearly something like the crack / the break in the screen.

So even if الكسر can mean other things in other contexts, here the screen makes the intended meaning obvious.

It is understandable and acceptable, but many Egyptians would say it in a more clearly colloquial way.

A very natural spoken Egyptian option is:

• الشرخ اللي في الشاشة صغير

This uses الشرخ, which is a very common word for crack.

Why add اللي?

• اللي means that / which
• So الشرخ اللي في الشاشة = the crack that is in the screen

Your original sentence is still fine, especially for learners and in written Arabic, but in everyday Egyptian speech, using اللي often sounds more natural.

No, you do not have to.

Both of these are understandable:

• الكسر في الشاشة صغير
• الكسر اللي في الشاشة صغير

The version with اللي is more explicitly like:

• The crack that is in the screen is small

In spoken Egyptian, many people prefer اللي because it makes the relationship clearer and sounds more conversational.

So:

• without اللي = shorter, a bit more neutral or compact
• with اللي = often more natural in everyday Egyptian speech

They look similar, but they do different jobs.

• الكسر الصغير = the small crack

  • This is a noun phrase
  • الصغير directly describes الكسر

• الكسر في الشاشة صغير = The crack in the screen is small

  • This is a full sentence
  • صغير is the predicate, not part of the noun phrase itself

So if you just want to name something, use a phrase like:

• الكسر الصغير في الشاشة = the small crack in the screen

If you want to make a statement, use:

• الكسر في الشاشة صغير = The crack in the screen is small
