قوة الفريق كبيرة.

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

So:

• قوة الفريق كبيرة literally looks like the strength of the team great
• but it means The team's strength is great or The strength of the team is great

This is completely normal in Modern Standard Arabic.
If you wanted was, Arabic would usually express that with a verb, but in the present tense, Arabic normally leaves is/am/are unstated.

This is a nominal sentence in Arabic, meaning a sentence that begins with a noun rather than a verb.

It has two main parts:

• قوة الفريق = the subject/topic
• كبيرة = the predicate/comment

So the sentence structure is:

• [subject] + [description]

Here, the subject is not just one word. It is the whole phrase قوة الفريق.

Because قوة الفريق is an iḍāfa construction, often translated as X of Y or Y's X.

In an iḍāfa:

• the first noun is called the possessed noun
• the second noun is called the possessor

Here:

• قوة = strength
• الفريق = the team

Together: قوة الفريق = the strength of the team / the team's strength

A key rule of iḍāfa is:

• the first noun does not take الـ
• the second noun determines whether the whole phrase is definite

Since الفريق is definite, the whole phrase قوة الفريق is definite.

Because it is the second noun in an iḍāfa construction.

In Arabic grammar, the second noun of an iḍāfa is put in the genitive case.

So in full vocalization, you would have:

• قُوَّةُ الفَرِيقِ كَبِيرَةٌ

Notice the ending on الفريقِ with -i in full case marking. That genitive ending happens because it follows the first noun in the iḍāfa.

Because it describes قوة, and قوة is a feminine noun.

In Arabic, adjectives must agree with the noun they describe in things like:

• gender
• number
• definiteness

Since قوة is feminine singular, the adjective must also be feminine singular:

• masculine: كبير
• feminine: كبيرة

So كبيرة is used, not كبير.

One strong clue is the ـة ending, called tāʾ marbūṭa.

Many Arabic nouns ending in ـة are feminine, including:

• قوة = strength
• سيارة = car
• مدينة = city

So learners often recognize feminine nouns by this ending, although there are some exceptions in Arabic overall.

In this kind of sentence, the predicate is usually indefinite.

So:

• قوة الفريق = a definite subject, because the iḍāfa is definite
• كبيرة = an indefinite predicate, meaning great/big

This is the normal pattern in Arabic nominal sentences.

If you said قوة الفريق الكبيرة, that would usually no longer mean The team's strength is great. Instead, it would sound more like the great strength of the team, where كبيرة is part of the noun phrase rather than the predicate of the sentence.

A fully vocalized version is:

قُوَّةُ الْفَرِيقِ كَبِيرَةٌ

This shows the grammatical endings more clearly:

• قُوَّةُ = subject, nominative
• الْفَرِيقِ = genitive, because it is the second part of iḍāfa
• كَبِيرَةٌ = predicate, nominative and indefinite

In pause, Arabic often drops the final case vowels in actual pronunciation, so learners commonly hear something closer to:

قوّة الفريق كبيرة

It is usually transliterated as quwwa.

A rough pronunciation guide:

• q = a deeper k sound, made farther back in the mouth
• u = short u
• ww = doubled w sound
• final a = short vowel from the tāʾ marbūṭa in pause

So it sounds roughly like QUW-wa.

In connected, fully inflected reading, it can be pronounced quwwatu, because of the nominative ending.

Both are correct.

The Arabic iḍāfa construction often corresponds to either:

• the team's strength
• the strength of the team

Which English version sounds better depends on style and context.

So:

• قوة الفريق = the team's strength = the strength of the team

This exact sentence is most natural as:

قوة الفريق كبيرة

because it starts with the subject and then gives the description.

Arabic does allow some flexibility in word order, but changing the order can affect emphasis or style. For a learner, the safest pattern is:

• subject first
• predicate second

So this sentence is a very standard and useful model.

Grammatically, it is an adjective in form, but in this sentence it functions as the predicate.

That means it is not just modifying a noun inside the phrase قوة الفريق. It is actually completing the statement about the subject.

So:

• in قوة كبيرة = great strength, كبيرة is an adjective inside a noun phrase
• in قوة الفريق كبيرة = The team's strength is great, كبيرة is the predicate of the whole sentence

That distinction is important in Arabic.
