هذه عيادة جديدة.

Because عيادة is a feminine singular noun, and the demonstrative this must match it in gender.

• هذا = this for masculine singular
• هذه = this for feminine singular

So with عيادة (clinic), you say هذه.

In Arabic, the verb to be is usually not stated in the present tense when you have a simple sentence like This is a new clinic.

So:

• هذه عيادة جديدة literally looks like this clinic new
• but it means This is a new clinic

This kind of sentence is called a nominal sentence in Arabic.

Because in Arabic, adjectives normally come after the noun they describe.

So:

• عيادة جديدة = a new clinic
• literally: clinic new

This is the normal order in Arabic, unlike English.

Because جديدة is describing عيادة, and Arabic adjectives must agree with the nouns they describe.

That means the adjective must match the noun in:

• gender
• number
• definiteness
• usually case as well

Since عيادة is feminine singular, the adjective is also feminine singular: جديدة.

Because the phrase is indefinite: a new clinic, not the new clinic.

In Arabic:

• عيادة جديدة = a new clinic
• العيادة الجديدة = the new clinic

The adjective matches the noun in definiteness too, so if the noun has الـ, the adjective must also have الـ.

You would say:

العيادة الجديدة

Both words become definite:

• العيادة = the clinic
• الجديدة = the new

If you wanted This is the new clinic, you could say:

هذه العيادة الجديدة

Here هذه is functioning as this on its own, not directly attached to a definite noun.

So the sentence is structured like:

• هذه = this
• عيادة جديدة = a new clinic

Together: This is a new clinic.

Because the noun after it is indefinite, the sentence is understood as a full statement, not just a noun phrase.

A careful MSA pronunciation is:

hādhihi ʿiyādatun jadīdatun

In normal pause, learners often hear something closer to:

hādhihi ʿiyādah jadīdah

A few notes:

• هذه = hādhihi
• عيادة begins with ʿayn (ع), a consonant that does not exist in English
• the final ة is often heard as -ah when pausing

Because Arabic is often written without short vowels and case endings in normal text.

The fully vocalized MSA form is:

هذه عيادةٌ جديدةٌ

Those ـٌ endings are tanwīn, showing the words are indefinite and here nominative.

In everyday reading and in pause, those endings are usually not pronounced clearly, so learners often hear:

هذه عيادة جديدة

Both represent the same sentence.

No. It is grammatically feminine, not biologically female.

In Arabic, many nouns for things and places are simply assigned a grammatical gender. One common sign of feminine nouns is the ending ة.

So عيادة is feminine because that is how the noun behaves grammatically, and that is why it takes:

• هذه
• جديدة

rather than masculine forms.

That letter is called tāʾ marbūṭa (ة). It is very often a marker of the feminine form.

In this sentence it helps show that both words are feminine singular.

Its pronunciation changes depending on context:

• in pause, it often sounds like -ah
• when followed by grammatical endings or in some connected forms, it can sound like t

That is why a fully vocalized form can be عيادةٌ but in pause you may hear عيادة as ʿiyādah.
