النار خطيرة.

A common Levantine pronunciation is:

ən-nār kha-ṭee-re

More naturally written for learners:

• ən-nār = the fire
• khaṭīre = dangerous (feminine)

A few pronunciation notes:

• ال in النار is pronounced ən- here because of sound changes with the next letter.
• The final ة in خطيرة is usually pronounced -e in Levantine, not -a.
• The stress is usually:
  • ən-NĀR
  • kha-ṬĪ-re

So the full sentence sounds roughly like: ən-NĀR kha-ṬĪ-re.

Because Arabic often leaves out the verb to be in the present tense.

So:

• النار خطيرة literally looks like the fire dangerous
• but it means The fire is dangerous

This is completely normal in Arabic.

If you wanted past tense, then Arabic would use a verb:

• كانت النار خطيرة = The fire was dangerous

So in the present tense, no is is needed.

Because النار is a feminine noun in Arabic.

In Arabic, adjectives must match the noun they describe in gender. Since النار is feminine, the adjective must also be feminine:

• masculine: خطير = dangerous
• feminine: خطيرة = dangerous

So:

• النار خطيرة = The fire is dangerous

Even though English does not treat fire as feminine, Arabic does.

Good question. In this sentence, خطيرة is not being used like the dangerous fire. It is the predicate of the sentence: dangerous in The fire is dangerous.

So:

• النار الخطيرة = the dangerous fire
  Here, خطيرة is an adjective directly describing the noun, so it takes ال too.
• النار خطيرة = the fire is dangerous
  Here, خطيرة is the predicate, so it normally stays indefinite.

This is an important difference in Arabic.

Because ن is a sun letter.

In Arabic, when ال comes before a sun letter, the l sound of ال disappears and the next consonant is doubled.

So:

• written: النار
• pronounced: an-nār or ən-nār in Levantine

You do not say al-nār in normal pronunciation.

This happens with other sun letters too, for example:

• الشمس → ash-shams
• الناس → an-nās

These are two sounds English speakers often ask about.

• خ: a rough, throaty sound, like the ch in German Bach or Scottish loch
• ط: an emphatic t sound; it is heavier and darker than a normal t

So خطيرة is not pronounced like a simple English katira. Try something closer to:

kha-ṭee-re

If you cannot make the emphatic ط perfectly yet, a plain t is often understood, but it is good to notice the difference early.

Yes, the sentence itself works in both.

Written:

• النار خطيرة

But the pronunciation differs a bit:

In Standard Arabic, you might hear:

• an-nāru khaṭīratun in fully formal grammar
• or a paused form closer to an-nār khaṭīra

In Levantine, a natural pronunciation is:

• ən-nār khaṭīre

The biggest Levantine clue here is the ending -e sound on خطيرة.

It follows a very common Arabic pattern:

definite noun + adjective/predicate

So:

• النار = the fire
• خطيرة = dangerous

Together:

• النار خطيرة = The fire is dangerous

This kind of sentence is called a nominal sentence. It starts with a noun, then gives information about it.

You can build many useful sentences this way:

• الأكلة طيبة = The food is tasty
• البنت ذكية = The girl is smart
• الجو حلو = The weather is nice

Yes, but it means something different.

• النار خطيرة = The fire is dangerous
• نار خطيرة = a dangerous fire

So adding or removing ال changes the meaning:

• النار = the fire
• نار = a fire / fire

This is the difference between a full sentence and a noun phrase.

No. خطير / خطيرة is a general adjective meaning dangerous or sometimes serious, depending on context.

Examples:

• الوضع خطير = The situation is serious/dangerous
• الطريق خطيرة = The road is dangerous
• المرض خطير = The illness is serious

In some colloquial contexts, خطير can even mean something like intense or awesome, but in this sentence it clearly means dangerous.

A common Levantine way is to use مو:

• النار مو خطيرة = The fire is not dangerous

You may also hear regional variants like مش:

• النار مش خطيرة

Both are common in spoken Arabic, depending on the area.

Usually, no—not in a basic sentence like this.

The most natural sentence is simply:

• النار خطيرة

Adding هي is usually unnecessary here and may sound marked or unnatural unless you are doing emphasis or a special structure.

For a beginner, the safest rule is:

• For simple present-tense sentences like The fire is dangerous, just say noun + adjective.

So stick with:

• النار خطيرة
