الشنطة زهرية.

A common Levantine pronunciation is:

ish-shanṭa zahriyye

or in some areas:

esh-shanṭa zahriyye

A few helpful notes:

• الـ often sounds like i/ e + doubled consonant before a sun letter.
• ش is a sun letter, so الشنطة is pronounced more like ish-shanṭa / esh-shanṭa, not al-shanṭa.
• زهرية is often pronounced zah-riy-ye in Levantine.

Because in Arabic, the verb to be is usually not said in the present tense.

So:

• الشنطة زهرية = The bag is pink

This kind of sentence is very normal in both spoken Levantine and standard Arabic-style grammar. Arabic simply puts:

• the thing being talked about: الشنطة
• then the description: زهرية

If you wanted was or will be, then Arabic would use an actual verb.

Because here it is the predicate of the sentence, not an adjective inside a noun phrase.

There is an important difference:

• الشنطة زهرية = The bag is pink
• الشنطة الزهرية = the pink bag

So:

• definite noun + indefinite adjective often makes a full sentence: The bag is pink
• definite noun + definite adjective makes one noun phrase: the pink bag

This is one of the most important patterns for learners to notice.

Yes. زهرية is the feminine form.

The noun شنطة is feminine, so the adjective has to match it.

• masculine: زهري
• feminine: زهرية

So if the noun is feminine, you use the feminine adjective form.

Examples:

• القلم زهري = The pen is pink
• الشنطة زهرية = The bag is pink

Usually, yes. In Arabic, a noun ending in ـة is very often feminine, and شنطة is feminine.

That is why the adjective also appears in the feminine form:

• شنطة زهرية
• not شنطة زهري

Of course, not every noun follows the simplest pattern, but in this case the ending is a very good clue.

It is a complete sentence.

Arabic can make a full present-tense sentence without using is. So this structure is complete:

• الشنطة = the bag
• زهرية = pink

Together: The bag is pink

If you wanted just a pink bag or the pink bag, the grammar would be different:

• شنطة زهرية = a pink bag
• الشنطة الزهرية = the pink bag

So the exact use of الـ matters a lot.

Not normally. That would sound wrong to most speakers because the adjective should agree with شنطة, which is feminine.

So the correct form is:

• الشنطة زهرية

not:

• الشنطة زهري

The masculine form زهري would be used with a masculine noun.

It is very natural in Levantine, and most Arabic speakers would understand it.

A couple of notes:

• شنطة is a very common everyday word for bag in many dialects.
• زهرية for pink is also very natural in spoken Arabic, especially colloquial speech.

In more formal Standard Arabic, you might more often see something like:

• الحقيبة وردية

But for Levantine conversation, الشنطة زهرية sounds normal and useful.

Sometimes, yes, depending on context. Arabic words built from زهر can relate to flowers, and زهرية can also be used in other meanings in different contexts.

But in this sentence:

• الشنطة زهرية

it is naturally understood as the color description: pink.

The sentence structure makes that interpretation clear.
