شاحنة النقل كبيرة.

In Arabic, present-tense sentences like this usually do not use a separate word for is / am / are.

So:

• شاحنة النقل كبيرة. = The transport truck is big.

This is a very common Arabic sentence pattern:

• noun phrase + adjective/predicate

The verb to be is normally left out in the present tense.

If you wanted the past, Arabic would use a verb, for example:

• كانت شاحنة النقل كبيرة. = The transport truck was big.

Because شاحنة is a feminine singular noun, and the describing word must match it.

• شاحنة = truck, lorry
• كبيرة = big (feminine singular form)

The masculine form is:

• كبير

So Arabic agrees in gender:

• كتاب كبير = a big book
• شاحنة كبيرة = a big truck

Since شاحنة النقل is feminine singular, كبيرة must also be feminine singular.

A major clue is the ending ـة (called tāʾ marbūṭa). Very often, nouns ending in ـة are feminine.

So:

• شاحنة is treated as feminine
• therefore anything describing it must also be feminine

This ending is one of the first things learners use to recognize feminine nouns in Arabic, although there are exceptions in the language as a whole.

Because this is an iḍāfa construction, often called a genitive/possessive construction.

Here:

• شاحنة = truck
• النقل = transport

Together:

• شاحنة النقل = the transport truck or literally the truck of transport

In an iḍāfa:

1. the first noun usually does not take ال
2. the second noun can be definite, and that makes the whole phrase definite

So:

• شاحنة النقل = the transport truck not
• الشاحنة النقل ✘

It is the second part of the iḍāfa, specifying what kind of truck this is.

So:

• شاحنة = truck
• النقل = transport, transportation

Together:

• شاحنة النقل = transport truck / freight truck / truck for transport

This is a very common Arabic way to express relationships that English might express with:

• of
• a compound noun
• sometimes an adjective-like noun

For example:

• باب البيت = the door of the house
• مدير المدرسة = the principal of the school
• شاحنة النقل = the transport truck

Here it is the predicate of the sentence, not just an adjective inside the noun phrase.

The sentence is:

• شاحنة النقل = the transport truck
• كبيرة = is big

So the structure is:

• subject + predicate

This is different from:

• شاحنة النقل الكبيرة

That means:

• the big transport truck

In that version, الكبيرة is an adjective modifying the noun inside the noun phrase.

So the difference is important:

• شاحنة النقل كبيرة = The transport truck is big.
• شاحنة النقل الكبيرة = The big transport truck.

Because it is the predicate, not part of the definite noun phrase.

In a sentence like this:

• شاحنة النقل is the subject
• كبيرة is what is being said about it

Arabic often keeps the predicate indefinite in this kind of nominal sentence.

Compare:

• شاحنة النقل كبيرة = The transport truck is big.
• شاحنة النقل الكبيرة = The big transport truck.

If you add ال to كبيرة, you are no longer saying is big; you are turning it into the big ... as part of the noun phrase.

Fully vocalized, it would be:

• شاحنةُ النقلِ كبيرةٌ

The endings are:

• شاحنةُ → nominative, because it is the first part of the subject
• النقلِ → genitive, because it is the second part of an iḍāfa
• كبيرةٌ → nominative, because it is the predicate

In normal modern writing, these short vowel endings are usually omitted, so learners often see:

• شاحنة النقل كبيرة

without the case vowels written.

In pronunciation, ال changes here because ن is a sun letter.

So although it is written:

• النقل

it is pronounced more like:

• an-naql

not

• al-naql

So the whole sentence is approximately:

• shāḥinat an-naql kabīrah

This is a regular pronunciation rule with ال before sun letters such as ت، د، ر، س، ش، ن, and others.

That is the normal order in Arabic.

Arabic usually puts:

• the noun first
• then the adjective or predicate after it

So:

• شاحنة كبيرة = a big truck
• شاحنة النقل كبيرة = the transport truck is big

This is similar to how adjectives work in Arabic generally: they usually follow the noun they describe.

Yes, but the basic and most neutral order is:

• شاحنة النقل كبيرة

That is the clearest and most standard version for learners.

Arabic can sometimes move elements for emphasis or style, but that is less basic and often more literary or context-dependent. For now, it is best to learn this sentence as:

• subject first
• predicate second

They are similar, but not identical.

• شاحنة النقل كبيرة = The transport truck is big

  • definite truck
  • full sentence

• شاحنة نقل كبيرة = often a big transport truck

  • this is more like a noun phrase, not a full sentence
  • نقل here is indefinite

So the version with النقل is a definite iḍāfa phrase, while the version without ال is more indefinite and usually understood differently.

A very literal breakdown is:

• شاحنة = truck
• النقل = the transport / transportation
• كبيرة = big

So literally:

• truck of transport [is] big

Natural English:

• The transport truck is big.

This kind of literal breakdown is often helpful for understanding Arabic structure, even when the natural English translation sounds different.
