التلفاز كبير.

In careful MSA pronunciation, it is:

at-tilfāzu kabīrun

A few helpful notes:

• التلفاز is written with الـ (the), but because ت is a sun letter, the l sound of ال assimilates.
• So you say at-tilfāz, not al-tilfāz.
• كبير is pronounced kabīr.

In normal unvocalized writing, you usually see:

التلفاز كبير

With full endings, it would be:

التلفازُ كبيرٌ

Because in Arabic, the present-tense to be is usually not stated in sentences like this.

So:

• التلفاز كبير = The television is big

This is completely normal in Arabic.
If you wanted a past or future meaning, Arabic would use a verb, but in the simple present it is usually omitted.

This is a nominal sentence.

It has two main parts:

• التلفاز = the subject
• كبير = the predicate / description

So the structure is basically:

• [noun] + [description]

Here, it means that the noun is being described:

• التلفاز كبير = The television is big

Because in Arabic, descriptive words usually come after the noun they describe.

So Arabic says:

• television big

rather than English:

• big television
• or the television is big

In this sentence, كبير is functioning as the predicate of the sentence, so it naturally follows the subject.

This is a very common question.

In التلفاز كبير, كبير is not part of the noun phrase the big television.
Instead, it is the predicate of the sentence:

• التلفاز = the television
• كبير = big

So the whole sentence means:

• The television is big

If you said:

• التلفاز الكبير

that would mean:

• the big television

So:

• التلفاز كبير = a full sentence
• التلفاز الكبير = a noun phrase

Because التلفاز is a masculine singular noun, and the adjective/predicate matches it in gender and number.

So:

• masculine singular noun → كبير
• feminine singular noun → كبيرة

For example:

• السيارة كبيرة = The car is big

Here, because التلفاز is masculine singular, كبير is the correct form.

The fully vowelled form is:

التلفازُ كبيرٌ

Those endings show that both words are in the nominative case here.

• التلفازُ
• كبيرٌ

In most everyday Arabic writing, these short vowels are omitted, so you usually just see:

التلفاز كبير

They are different structures:

• التلفاز كبير = The television is big
• التلفاز الكبير = the big television

So the first one is a sentence, while the second one is just a noun phrase.

A useful shortcut:

• if both words are definite with الـ, it is often a noun phrase
• if the first is definite and the second is indefinite, it is often a sentence like X is Y

No. التلفاز is a standard MSA word, but you may also see or hear:

• التلفزيون

Both are used, and learners will encounter both forms.
In formal MSA, التلفاز is perfectly good and common in educational materials.

Not for the same meaning.

If you want to say The television is big, the normal order is:

• التلفاز كبير

Putting كبير first would not be the normal simple way to say this meaning.

So for beginners, the safe pattern is:

• definite noun + adjective/predicate

Example:

• البيت كبير
• الشارع طويل
• التلفاز كبير
