البيت كبير.

In Egyptian Arabic, it is usually pronounced el-bēt kibīr.

A few helpful notes:

• الـ is usually pronounced el- or sometimes il- in Egyptian.
• بيت sounds like bēt.
• كبير sounds like kibīr.

So the whole sentence is: el-bēt kibīr.

الـ is the Arabic definite article, like the in English.

So:

• بيت = house
• البيت = the house

In Egyptian Arabic, الـ is commonly pronounced el-.

In Arabic, simple present-tense sentences often do not use a separate word for is.

So:

• البيت كبير literally looks like the house big
• but it naturally means the house is big

This is completely normal in Arabic.
If you want other tenses, then a verb can appear, for example in the past or future.

Arabic normally puts adjectives after the noun they describe.

So:

• بيت كبير = a big house
• البيت الكبير = the big house

But in البيت كبير, كبير is not just an adjective inside a noun phrase. It is the predicate of the sentence, meaning something like the house — big.

So the order is normal and natural.

Because in this sentence, كبير is the predicate, not part of the noun phrase.

Compare these two:

• البيت كبير = the house is big
• البيت الكبير = the big house

In البيت الكبير, the adjective is directly describing the noun inside one phrase, so it also takes الـ.

In البيت كبير, the sentence is making a statement about the house, so كبير stays without الـ.

The spelling البيت كبير works for both Egyptian Arabic and Standard Arabic.

The difference is mostly in pronunciation:

• Egyptian Arabic: el-bēt kibīr
• Standard Arabic: al-baytu kabīrun if fully pronounced with case endings

So an Egyptian learner can absolutely use this written sentence, but pronounce it in the Egyptian way.

Arabic normally leaves out most short vowels in everyday writing.

So even though you see:

• البيت كبير

a speaker already knows how to read it from vocabulary and context:

• el-bēt kibīr

This is very normal in Arabic writing. Textbooks may add vowel marks for learners, but regular writing usually does not.

Yes. Adjectives in Arabic change to match gender and number.

Here, البيت is masculine singular, so:

• البيت كبير = the house is big

If the noun were feminine, you would usually use كبيرة:

• البنت كبيرة = the girl is big / older
• العربية كبيرة = the car is big

So كبير is the masculine singular form.

Not for the same basic meaning.

The normal way to say the house is big is:

• البيت كبير

If you say كبير البيت, that does not sound like the normal everyday Egyptian way to express this sentence. It could sound unnatural, poetic, or like part of a different structure.

For a beginner, the safe pattern is:

• noun + adjective/predicate
• البيت كبير

In Egyptian Arabic, you would usually use مش:

• البيت مش كبير = the house is not big

This is a very common Egyptian pattern:

• أنا تعبان = I am tired
• أنا مش تعبان = I am not tired

So for this sentence:

• البيت كبير = the house is big
• البيت مش كبير = the house is not big
