الكون كبير.

A natural Egyptian pronunciation is:

el-kōn kibīr

Roughly:

• الكون → el-kōn
• كبير → kibīr

A more detailed guide:

• el sounds like ell
• kōn rhymes roughly with cone
• ki sounds like ki in kid, but shorter
• bīr has a long ee sound

So the whole sentence sounds like:

el-kōn kibīr

In Arabic, the verb to be is usually not said in the present tense.

So instead of saying:

• The universe is big

Arabic simply says:

• The universe big

That is completely normal and grammatical.

If you wanted a past or future meaning, then Arabic would use words equivalent to was or will be, but in the present tense they are normally omitted.

الـ is the Arabic definite article, meaning the.

So:

• كون = universe / cosmos
• الكون = the universe

In Egyptian Arabic, الـ is usually pronounced el-.

So الكون is pronounced el-kōn.

Because كبير here is not the big as part of a noun phrase. It is the predicate adjective: it tells us something about the universe.

So the structure is:

• الكون = the subject
• كبير = big

This means:

• The universe is big

In Arabic, predicate adjectives are usually indefinite, so they do not take الـ.

Compare:

• الكون كبير = The universe is big.
• الكون الكبير = the big universe

That difference is very important.

They look similar, but they mean different things.

• الكون كبير = The universe is big

  • full sentence
  • كبير is the predicate adjective

• الكون الكبير = the big universe

  • noun phrase, not a complete sentence by itself in most contexts
  • الكبير describes الكون directly

A useful shortcut:

• If both words are definite with الـ, it often means the big X
• If the first is definite and the adjective is not, it often means X is big

Yes. Arabic adjectives agree with the noun in gender and number.

الكون is:

• masculine
• singular

So the adjective is also:

• masculine
• singular → كبير

If the noun were feminine, you would usually use كبيرة instead.

For example:

• الدنيا كبيرة = The world/life is big

So كبير matches الكون correctly.

The feminine form is كبيرة.

Examples:

• البنت كبيرة = The girl is big / older
• السيارة كبيرة = The car is big

Since الكون is masculine, we use كبير, not كبيرة.

It works in both, but it feels very natural and straightforward in both Modern Standard Arabic and Egyptian Arabic.

The main Egyptian feature you’ll notice is the pronunciation of الـ as el- in speech:

• الكون → el-kōn

The words themselves are not especially colloquial, so a learner may hear or read this sentence in either variety.

Because the next letter is ك, and ك is a moon letter.

In Arabic, the ل in الـ is pronounced clearly before moon letters.

So:

• الكون = el-kōn

If the next letter were a sun letter, the ل sound would assimilate. But with ك, it stays.

Not for the same meaning.

الكون كبير is the normal way to say:

• The universe is big

If you say كبير الكون, it does not work as the regular equivalent of that sentence. It may sound poetic, unnatural, or incomplete depending on context.

For a basic learner, stick with:

• الكون كبير

In a sentence like this, yes.

Arabic commonly uses:

• subject + adjective

So:

• الكون كبير = The universe is big
• البيت واسع = The house is spacious
• الجو جميل = The weather is nice

But remember: this is a sentence pattern, not just a noun followed by an adjective inside one phrase.

That is why:

• البيت واسع = The house is spacious but
• البيت الواسع = the spacious house

Normally, no. In simple present-tense equational sentences, Arabic usually does not need a separate word like he/it is.

So the natural sentence is:

• الكون كبير

Adding هو here would usually sound unnecessary or unnatural for a beginner-level neutral sentence.

Not always. كبير can mean:

• big
• large
• great
• old/older
• important/senior

The exact meaning depends on context.

In الكون كبير, the natural meaning is physical or conceptual vastness:

• The universe is big

So here كبير is about size or vast extent.
