الطفل نام بالبيت.

A common Levantine-style pronunciation is eṭ-ṭefel naam bil-bēt or iṭ-ṭefel naam bil-bēt, depending on the region.

A few quick notes:

• نام has a long aa sound: naam
• بيت is usually bēt in Levantine, not bayt
• بالبيت is often pronounced bil-bēt or bel-bēt

Because ط is a sun letter. In Arabic, when ال comes before a sun letter, the l sound assimilates to the next consonant.

So:

• written: الطفل
• pronounced more like: aṭ-ṭifl in careful Standard Arabic
• in Levantine, often more like eṭ-ṭefel

So the spelling stays the same, but the pronunciation changes.

نام is the past tense verb, third person masculine singular.

So it matches a subject like الطفل because الطفل is singular and masculine.

The verb comes from the root related to sleep: ن-و-م.

Arabic often does not need a separate subject pronoun if the subject is already clear.

Here, the subject is explicitly stated as الطفل, so you do not need to add هو.

Also, the verb نام already shows a masculine singular subject, so the grammar is clear even without a separate pronoun.

Because بـ is a preposition that attaches directly to the noun.

So:

• بـ = in / at / with depending on context
• البيت = the house / the home
• together: بالبيت

This is very normal in Arabic. Prepositions like بـ, لـ, and كـ often attach to the following word.

In Arabic spelling, short prepositions like بـ are usually attached to the word after them.

Also, when بـ comes before a word with ال, they combine in writing:

• بـ + البيت
• becomes بالبيت

So this is not a special exception; it is the normal spelling.

In Levantine, بالبيت can often mean either:

• in the house
• at home

The exact English wording depends on context. In everyday speech, البيت often means home as much as house.

So this phrase can sound more natural in English as at home, even though the Arabic is literally built from in/at + the house/home.

Yes. That word order is also natural.

Both are possible:

• الطفل نام بالبيت
• نام الطفل بالبيت

Very roughly:

• الطفل نام بالبيت is more subject-first, which is very common in spoken Levantine
• نام الطفل بالبيت is more verb-first, which is also very natural in Arabic

The difference is usually about style, flow, or emphasis, not basic meaning.

It is understandable and correct, but it can sound a bit more formal or bookish than some everyday alternatives.

In casual speech, many speakers might more often say something like:

• الولد for the boy / the kid
• sometimes other local everyday words depending on region and context

So الطفل نام بالبيت is fine, but الطفل itself is a little less colloquial than some alternatives.

In Levantine, بـ very often does the job that في might do in other contexts.

So بالبيت is a very natural colloquial way to say at home / in the house.

You may also hear في البيت, and people will understand it, but بالبيت is extremely common in Levantine everyday speech.

Levantine Arabic normally does not use the full case endings of Standard Arabic in everyday speech.

So in spoken Levantine, you simply say:

• الطفل نام بالبيت

You do not pronounce endings like:

• -u
• -a
• -i

That is one reason spoken Arabic often sounds simpler than fully vocalized Standard Arabic.

Then the verb would usually change to the feminine form:

• البنت نامت بالبيت

The key change is:

• نام = masculine singular
• نامت = feminine singular

So the verb agrees with the subject in gender and number.
