فراء القطة نظيف حقا.

Because فراء القطة is an iḍāfa construction, often called a possessive phrase.

It works like:

• فراء = fur
• القطة = the cat

Together, فراء القطة means the cat's fur or the fur of the cat.

In Arabic, the possessed thing comes first, and the owner comes second. So Arabic says:

• fur the-cat not
• the-cat's fur with an apostrophe like English

That is a very common Arabic pattern.

This is a key feature of the iḍāfa construction.

In فراء القطة:

• the first noun (فراء) does not take ال
• the second noun (القطة) determines whether the whole phrase is definite

Since القطة is definite because it has ال, the whole phrase فراء القطة is also definite.

So:

• فراء قطة = a cat's fur / the fur of a cat
• فراء القطة = the cat's fur

Even without ال on فراء, the whole phrase is definite.

In fully vowelled, formal Arabic, the adjective would normally match the noun phrase in definiteness:

• فِراءُ القِطَّةِ نَظيفٌ = less precise in full grammatical agreement
• فِراءُ القِطَّةِ النَّظيفُ would be the fully definite adjective if used as a direct attributive adjective

However, in normal unvowelled writing and in very common usage, especially in simple sentences, Arabic often uses the adjective as the predicate of the sentence rather than as part of the noun phrase.

So the structure is:

• فراء القطة = subject
• نظيف = predicate adjective, is clean
• حقا = really

So the sentence is understood as:

• The cat's fur is really clean

Since نظيف is functioning as the predicate, it does not need ال.

It is a nominal sentence.

Arabic has two major sentence types:

• verbal sentences: usually begin with a verb
• nominal sentences: usually begin with a noun or noun phrase

This sentence begins with فراء القطة, a noun phrase, so it is nominal.

Its basic structure is:

• subject/topic: فراء القطة
• predicate/comment: نظيف حقا

Arabic often does not need a separate word for is in the present tense, so نظيف carries the meaning is clean.

It is not written, because Arabic usually omits the present-tense to be.

So:

• فراء القطة نظيف literally looks like the cat's fur clean
• but it means the cat's fur is clean

This is normal in Arabic. The verb to be is usually only expressed in other tenses, such as past or future.

For example:

• كان فراء القطة نظيفًا = the cat's fur was clean

حقا means really, truly, or indeed.

In this sentence, it strengthens the statement:

• فراء القطة نظيف حقا = The cat's fur is really clean

It acts like an adverb.

You may also see it written with full vowels as حَقًّا. In unvowelled text, it is often simply written حقا.

A common pronunciation is approximately:

• firāʾ

Breakdown:

• ف = f
• ر = rolled or tapped r
• اء at the end includes a long ā sound followed by a hamza stop

So it is not just firaa smoothly; there is a slight stop at the end because of the hamza.

Also, فراء means fur, not just any hair. It is specifically animal fur.

Because of the spelling:

• القطة

The ط is doubled due to the shadda on it in the fully vowelled form: القِطَّة.

So it is pronounced roughly:

• al-qiṭṭa

Also notice:

• the final ة (tāʾ marbūṭa) is usually pronounced like -a when pausing
• in connected grammatical pronunciation, it may sound like -at depending on the context

In normal citation pronunciation, learners usually say al-qiṭṭa.

The adjective agrees with فراء, not with القطة.

The thing being described is:

• فراء القطة = the cat's fur

The head noun of the phrase is فراء, and that noun is grammatically masculine. So the adjective is masculine:

• نظيف

It is not describing القطة directly. It is describing the fur.

This is very important in Arabic: in a phrase like X of Y, adjectives usually agree with X, the first noun.

Yes. In full formal grammar, you could write it with case endings.

A common fully vowelled form would be:

• فِراءُ القِطَّةِ نَظيفٌ حَقًّا

Here is what is happening:

• فِراءُ = nominative, because it is the subject
• القِطَّةِ = genitive, because it is the second term of the iḍāfa
• نَظيفٌ = nominative predicate
• حَقًّا = adverbial accusative expression

In everyday reading, short vowels and case endings are usually omitted, so learners usually see:

• فراء القطة نظيف حقا

Sometimes, but the meaning is a little different.

• فراء usually refers to fur, especially the furry coat of an animal
• شعر usually means hair

For a cat, فراء is the more natural choice if you want to emphasize its fur coat. شعر القطة could be understood, but فراء القطة is better in this context.

Yes, but the basic version given is the most straightforward.

Standard order here is:

• فراء القطة نظيف حقا

You might also hear or read stylistic variations for emphasis, but for a learner, this is the best pattern to follow:

• noun phrase
• adjective/predicate
• adverb

So if you want to make similar sentences, you can model them like this:

• بيت الرجل كبير جدا = the man's house is very big
• لون السماء جميل حقا = the color of the sky is really beautiful

Yes. In fully vowelled spelling, it is often written:

• حَقًّا

This includes:

• fatḥa
• tanwīn fatḥ
• a written alif
• and a doubled q sound because of the shadda

In ordinary text, these marks are usually omitted, so it appears as:

• حقا

That is completely normal. Learners should be aware that unvowelled Arabic often hides details that would be visible in a textbook-style fully vowelled form.
