التغليف نظيف.

Because Arabic often uses a nominal sentence in the present tense, with no written or spoken copula like is/am/are.

So:

• التغليف نظيف
• literally: the packaging clean
• natural English: The packaging is clean

This is completely normal in Modern Standard Arabic.

If you wanted the past tense, you would usually add a verb such as كان:

• كان التغليف نظيفًا = The packaging was clean

Because نظيف is not acting as a simple adjective inside a noun phrase here. It is the predicate of the sentence.

So the structure is:

• التغليف = the subject
• نظيف = the predicate, describing the subject

In Arabic nominal sentences, the predicate is often indefinite, so it usually does not take الـ.

Compare:

• التغليف نظيف = The packaging is clean
• التغليف النظيف = the clean packaging

That second one is a noun phrase, not a complete sentence.

It is adjective-like in meaning, but grammatically in this sentence it functions as the predicate (خبر) of the nominal sentence.

So:

• in التغليف النظيف → نظيف is an adjective modifying التغليف
• in التغليف نظيف → نظيف is the predicate meaning is clean

This distinction is very important in Arabic.

A common pronunciation is:

• at-taghlīf naẓīf

A more detailed breakdown:

• التغليف = at-taghlīf
• نظيف = naẓīf

A few sound notes:

• غ is a voiced guttural sound, often approximated by a French-style r or a gargled gh
• ظ is an emphatic z sound
• ي here gives the long vowel ī

If full case endings are pronounced, it would be:

• at-taghlīfu naẓīfun

But in normal pause pronunciation, people often say:

• at-taghlīf naẓīf

Because التغليف is treated as a masculine singular noun in Arabic, so the predicate agrees with it:

• التغليف نظيف = correct

If the noun were feminine singular, you would use نظيفة instead:

• العلبة نظيفة = The box is clean

Arabic adjectives and predicates usually agree with the noun in gender and number.

Yes. التغليف is a noun meaning packaging, packing, or wrapping, depending on context.

It is also a verbal noun (مصدر) related to the root غ ل ف, which has to do with covering or wrapping.

So التغليف can refer to:

• the act of packaging
• the packaging material
• the wrapping/outer covering

In a sentence like التغليف نظيف, it most naturally means something like:

• The packaging is clean
• The wrapping is clean

This is one of the most useful contrasts for learners.

• التغليف نظيف = The packaging is clean

  • complete sentence
  • نظيف is the predicate

• التغليف النظيف = the clean packaging

  • noun phrase only
  • النظيف is an adjective modifying التغليف

So if both words are definite with الـ, you usually get a noun phrase, not a full present-tense sentence.

Yes, in fully vowelled formal Arabic, the sentence would usually be written:

• التغليفُ نظيفٌ

with:

• التغليفُ = nominative subject
• نظيفٌ = nominative predicate

However, in everyday printed Arabic, short vowels and case endings are usually omitted, so you normally see:

• التغليف نظيف

Both represent the same sentence.

Yes, but التغليف نظيف is the most straightforward order.

This is the normal pattern:

• subject + predicate
• التغليف نظيف

Arabic can sometimes put the predicate first for style, emphasis, or context, but for a learner, the basic and safest pattern is the one you see here.

So this sentence is a very standard example of a simple nominal sentence.

A common way is to use ليس:

• التغليف ليس نظيفًا = The packaging is not clean

Notice that after ليس, the predicate typically appears in the accusative in fully marked Arabic:

• نظيفًا

But in unvowelled text, you will often just see:

• التغليف ليس نظيف

For learning purposes, it is good to know both the simple affirmative:

• التغليف نظيف

and the negative:

• التغليف ليس نظيفًا

Because ت is a sun letter (حرف شمسي).

When الـ comes before a sun letter, the l sound is assimilated to the following consonant. So:

• underlying form: al-taghlīf
• actual pronunciation: at-taghlīf

In writing, the spelling does not change:

• التغليف

But in pronunciation, the l is not heard.

You would make it a noun phrase with adjective agreement:

• تغليف نظيف = clean packaging / clean wrapping
• التغليف النظيف = the clean packaging

Notice the agreement rules:

• if the noun is indefinite, the adjective is also indefinite
• if the noun is definite, the adjective is also definite

So:

• التغليف نظيف = sentence: The packaging is clean
• التغليف النظيف = phrase: the clean packaging

That contrast is one of the key grammar points illustrated by this sentence.
