الفرو نظيف.

A common Levantine-style pronunciation is roughly il-farw nḍīf or el-farw ndeef.

A few helpful notes:

• الـ is usually pronounced il- or el- in Levantine.
• In الفرو, the ل is pronounced clearly because ف is a moon letter.
• نظيف is often heard as nḍīf / ndeef in Levantine speech, while a more Standard-Arabic-style pronunciation is naẓīf.

If your pronunciation is a bit closer to Standard Arabic at first, that is completely fine.

Because Arabic usually does not use a present-tense verb for to be in simple sentences like this.

So:

• الفرو نظيف literally looks like the fur clean
• but it means the fur is clean

This is normal in both Levantine and Standard Arabic. English needs is, but Arabic usually leaves it out in the present tense.

It is a full sentence.

In Arabic, a sentence like this is called a nominal sentence:

• الفرو = the subject
• نظيف = the predicate / description

So the structure is:

• [noun] + [adjective/description]
• meaning [noun] is [adjective]

Because that is the normal word order in Arabic.

In English, we say:

• clean fur

But in Arabic, adjectives usually come after the noun:

• فرو نظيف = clean fur
• literally fur clean

And in a sentence like الفرو نظيف, the same order is kept:

• the fur is clean

So for English speakers, the main habit to build is: noun first, adjective after.

Because الفرو نظيف and الفرو النظيف mean different things.

• الفرو نظيف = The fur is clean.
• الفرو النظيف = the clean fur

So:

• when the adjective is part of a sentence predicate, it does not take ال
• when the adjective is directly describing a noun inside a noun phrase, it does take ال if the noun is definite

This is a very important Arabic pattern.

Because الفرو is the definite noun phrase the fur, while نظيف is the predicate adjective clean.

In Arabic:

• attributive adjectives agree in definiteness
  
  • الفرو النظيف = the clean fur
• predicate adjectives usually stay indefinite
  • الفرو نظيف = the fur is clean

So the lack of ال on نظيف is exactly what you expect here.

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

Here, الفرو is treated as masculine singular, so the adjective is:

• نظيف = masculine singular

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

• نظيفة

So agreement is an important part of understanding why the adjective has this exact form.

Usually, in a simple sentence like this, no—the most natural form is just:

• الفرو نظيف

Adding هو would usually sound unnecessary, or it might add contrast/emphasis in a special context.

So if you just want a neutral statement, leave it out.

The basic structure is the same in both.

So this sentence works in both:

• الفرو نظيف

The main differences are:

• pronunciation
• the fact that Levantine usually drops formal endings

In fully vowelled Standard Arabic, you might see:

• الفروُ نظيفٌ

In everyday Levantine, those case endings are not pronounced.

Not as the normal, neutral way to say it.

The usual order is:

• الفرو نظيف

Starting with نظيف would sound marked, literary, or strongly emphatic in many contexts. For everyday speech, stick with:

• subject first
• description second

Because normal Arabic spelling usually leaves out most short vowels.

So in everyday writing, you see:

• الفرو نظيف

not a fully vowelled version.

Learners have to know the pronunciation from:

• vocabulary knowledge
• context
• listening practice
• dictionaries or teaching materials

This is one of the biggest adjustments for English speakers learning Arabic.
