الاضاءة قوية.

A careful pronunciation would be something like il-iDAA'a 'awiyye.

A few notes:

• الإضاءة is the more standard spelling, and it sounds roughly like il-iDAA-a with a small catch in the throat before the last vowel.
• قوية in many Levantine accents is pronounced 'awiyye, because ق is often pronounced as a glottal stop ' rather than a hard q sound.
• So the full sentence is roughly: il-iDAA'a 'awiyye.

If you learned Standard Arabic pronunciation, you may also hear al-iDaa'a qawiyya.

Because Arabic usually leaves out is/am/are in the present tense.

So:

• الاضاءة قوية literally looks like the lighting strong
• but it means The lighting is strong

This is very normal in both Standard Arabic and Levantine-style Arabic sentences of this type.

If you want the past tense, then a form of كان is used:

• الاضاءة كانت قوية = The lighting was strong

In Arabic, adjectives normally come after the noun they describe.

So the pattern is:

• noun + adjective

Here:

• الاضاءة = the lighting
• قوية = strong

So Arabic says:

• الاضاءة قوية not
• قوية الاضاءة in normal simple usage

This is one of the biggest word-order differences from English.

Because الاضاءة is a feminine noun, so the adjective has to match it.

• قوي = strong, masculine
• قوية = strong, feminine

Since الإضاءة is feminine, the correct form is:

• الإضاءة قوية

If the noun were masculine, you would use قوي:

• الضو قوي = The light is strong

Because when a noun is definite in Arabic, its adjective usually matches it in definiteness too.

Here:

• الاضاءة = the lighting
• القوية would literally mean the strong if used as an attributive adjective after a noun

But in this sentence, قوية is the predicate adjective in a complete statement, so it usually appears without ال:

• الاضاءة قوية = The lighting is strong

Compare:

• الاضاءة القوية = the strong lighting
  This is a noun phrase, not a full sentence.
• الاضاءة قوية = The lighting is strong
  This is a complete sentence.

It is understandable, but it sounds a bit more formal or written than the most everyday Levantine choice.

In casual Levantine, people often say:

• الضو قوي = The light is strong
• الإنارة قوية can also be used depending on context

So:

• الإضاءة قوية is fine and clear
• but الضو قوي often sounds more natural in daily speech

The exact choice depends on context:

• room lighting
• phone screen brightness
• stage lighting
• photography lighting

They are related, but not exactly the same.

• الإضاءة usually means lighting or illumination
• الضو usually means light

So:

• الإضاءة قوية can sound like The lighting is strong/intense
• الضو قوي sounds more like The light is strong/bright

In many everyday situations, الضو is the more common spoken word in Levantine.

The fully standard spelling is الإضاءة.

Why?

• The word begins with a hamza under the alif, so standard spelling writes it as إ
• It also contains a hamza later in the word: إضاءة

So in careful writing:

• الإضاءة قوية

But in informal writing, people sometimes leave hamzas out, so you may see:

• الاضاءة قوية

That informal spelling is common online, but the standard spelling is الإضاءة.

No, not if you keep the noun الإضاءة.

Because الإضاءة is feminine, the adjective must also be feminine:

• الإضاءة قوية ✅
• الإضاءة قوي ❌

But if you switch to a masculine noun, then قوي is correct:

• الضو قوي ✅

So the adjective changes based on the gender of the noun.

The -ة ending, called taa marbuuTa, often marks a noun or adjective as feminine.

In this sentence:

• الإضاءة ends in -ة, and it is feminine
• قوية also ends in -ة, because it is the feminine form of strong

This is one of the most useful clues for learners:

• قوي = masculine
• قوية = feminine

It does not always guarantee gender in every word, but it is a very common pattern.
