هذه باقة اقتصادية.

A careful MSA pronunciation is:

hādhihi bāqatun iqtiṣādiyyatun

In less formal reading, the case endings are often dropped, so you may hear something closer to:

hādhihi bāqa iqtiṣādiyya

A few sound notes:

• ذ in هذه sounds like th in this
• ق in باقة is qāf, a deeper k/q sound
• ة at the end of a word is usually pronounced like -a in pause, but it becomes -t when full endings are pronounced, as in باقةٌ = bāqatun

هذه means this for a feminine singular noun.

The noun باقة is feminine, so Arabic uses the feminine demonstrative هذه, not the masculine هذا.

So:

• هذا = this (masculine)
• هذه = this (feminine)

Because باقة is feminine, the sentence begins with هذه.

In Arabic, the verb to be is usually not stated in the present tense.

So هذه باقة اقتصادية literally looks like:

this economical package

But it means:

This is an economical package.

This is very normal in Arabic. These are called nominal sentences.

This is one of the most common learner questions.

In هذه باقة اقتصادية, هذه is the subject, meaning this, and باقة اقتصادية is the predicate, meaning an economical package.

So the structure is:

• هذه = this
• باقة اقتصادية = an economical package

That is why باقة is indefinite here.

If you said هذه الباقة الاقتصادية, that would mean this economical package as a noun phrase, not necessarily This is an economical package as a full identifying sentence.

In Arabic, adjectives normally come after the noun they describe.

So:

• باقة اقتصادية = an economical package

not:

• اقتصادية باقة

This is the normal Arabic order:

noun + adjective

Arabic adjectives agree with the noun they describe in:

• gender
• number
• definiteness
• and in fully vocalized Arabic, case as well

Since باقة is:

• feminine
• singular
• indefinite

the adjective must also be:

• feminine
• singular
• indefinite

So:

• باقة → feminine singular indefinite
• اقتصادية → feminine singular indefinite

That agreement is why اقتصادية ends the way it does.

The ending ة is called tāʾ marbūṭa, and it often marks a word as feminine.

Here:

• باقة is a feminine noun
• اقتصادية is a feminine adjective agreeing with it

So both words take feminine forms.

A useful thing to know:

• in pause, ة is usually pronounced -a
• with case endings or in certain grammatical contexts, it is pronounced -t

That is why you may see or hear bāqah in pause, but bāqatun in full MSA pronunciation.

In fully vocalized formal MSA, the sentence is:

هَذِهِ بَاقَةٌ اقْتِصَادِيَّةٌ

Both باقةٌ and اقتصاديةٌ take ḍamma tanwīn (-un) because they are in the nominative here.

That happens because:

• هذه is the subject
• باقة اقتصادية is the predicate
• both parts of a simple nominal sentence are nominative in standard grammar

In everyday speech and in much modern reading, these endings are often not pronounced.

In this form, it is best understood as a full sentence:

This is an economical package.

That is because هذه stands on its own as the subject, and باقة اقتصادية is the predicate.

If you want a simple noun phrase meaning this economical package, Arabic more typically uses:

هذه الباقة الاقتصادية

So the presence or absence of الـ helps show the difference.

Usually, هذه باقة اقتصادية is understood more naturally as:

This is an economical package.

If you want to say This package is economical, Arabic more naturally uses a definite noun:

هذه الباقة اقتصادية

Here:

• هذه الباقة = this package
• اقتصادية = economical

So the sentence in your example is more of an identification/classification sentence, while هذه الباقة اقتصادية is more clearly a description of a known package.

باقة can mean different things depending on context, such as:

• a bouquet
• a bundle
• a package
• a plan or offer in commercial language

So learners sometimes get confused because the dictionary’s first meaning may be bouquet, while in ads, telecom, or business contexts it often means package.

That is normal. Arabic words often have a wider range of meanings than a single English word.
