الزبون غاضب.

In careful Modern Standard Arabic with full case endings, it is:

az-zabūnu ghāḍibun

In pause, which is how it is often actually said aloud, you will often hear:

az-zabūn ghāḍib

A few pronunciation notes:

• الزبون begins with الـ plus ز, and ز is a sun letter, so l assimilates:
  • not al-zabūn
  • but az-zabūn
• غ in غاضب is a deep, throaty sound often transliterated gh
• ū in زبون is a long vowel

Because Arabic often uses a nominal sentence in the present tense, with no overt verb for to be.

So:

• الزبون غاضب = The customer is angry

This is completely normal Arabic.

If you wanted the past or future, then Arabic does use verbs:

• كان الزبون غاضبًا = The customer was angry
• سيكون الزبون غاضبًا = The customer will be angry

So in the present tense, Arabic usually just puts the subject and predicate next to each other.

Functionally, it is the predicate of the sentence: it tells you something about الزبون.

So the structure is:

• الزبون = the subject
• غاضب = the predicate

In English grammar terms, angry is an adjective, and in Arabic غاضب is also adjective-like. More specifically, it is the active participle of the verb غضب (to be angry / become angry), but here it simply means angry.

So yes, it behaves like an adjective in meaning, but in this sentence its job is to be the predicate.

Because this is not a single noun phrase like the angry customer. It is a full sentence:

• الزبون غاضب = The customer is angry

Arabic commonly puts:

• subject first
• predicate second

So غاضب comes after الزبون because it is saying something about the subject.

Compare:

• الزبون غاضب = The customer is angry
• الزبون الغاضب = the angry customer

That second one is a noun phrase, not a full sentence.

Because الزبون is definite: the customer.

But غاضب is the predicate, and predicates in sentences like this are often indefinite in form.

So:

• الزبون غاضب literally has the pattern the-customer angry
• in natural English: The customer is angry

If you made both words definite:

• الزبون الغاضب

that would usually mean:

• the angry customer

So the lack of الـ on غاضب helps show that this is a sentence, not just a noun phrase.

With full case endings, the sentence is:

الزَّبُونُ غاضِبٌ

or transliterated:

az-zabūnu ghāḍibun

Why these endings?

• الزبونُ takes ـُ because it is the subject of a nominal sentence
• غاضبٌ takes ـٌ because it is the predicate and is indefinite

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

الزبون غاضب

Because ز is a sun letter.

When الـ comes before a sun letter, the l sound assimilates to the next consonant. So:

• written: الزبون
• pronounced: az-zabūn

The spelling usually stays the same, but in fully vocalized text you would see a shadda on the ز to show the doubling:

الزَّبُون

So this is a pronunciation rule, not a change in meaning.

Yes. In a sentence like this, the predicate normally agrees with the subject in gender and number.

Here both are masculine singular:

• الزبون غاضب = The customer is angry

If the subject were feminine singular, the predicate would also change:

• الزبونة غاضبة = The female customer is angry

If plural, the form would also change accordingly.

So غاضب is masculine singular because الزبون here is understood as masculine singular.

This is a very important distinction.

1. الزبون غاضب

This is a full sentence:

• The customer is angry

Here, غاضب is the predicate.

2. الزبون الغاضب

This is a noun phrase:

• the angry customer

Here, الغاضب is an attributive adjective describing the noun directly.

A useful shortcut:

• no second الـ → often a sentence
• matching الـ on both words → often a noun + adjective phrase

The two words are:

• زبون = customer
• غاضب = angry

More specifically:

• زبون is a noun
• غاضب is an active participle/adjectival form from the verb غضب

In the sentence, زبون appears as الزبون because it has the definite article الـ, so it means the customer.

Yes. زبون can mean customer, and depending on context it can also be understood as client.

So الزبون غاضب could be translated as:

• The customer is angry
• The client is angry

The best English choice depends on context, such as whether you are talking about a shop, a service business, or a professional relationship.
