القوة مهمة.

A common Levantine-style pronunciation is il-ʔuwwa mhimme.

A few notes:

• القوة is often pronounced il-ʔuwwa by speakers who pronounce ق as a glottal stop.
• Some speakers keep ق as q, so you may also hear el-quwwa.
• مهمة in everyday Levantine is usually pronounced mhimme, rather than the more formal muhimma.

So this sentence may sound more colloquial as il-ʔuwwa mhimme.

Because Arabic normally leaves out the present-tense to be in sentences like this.

So Arabic says, literally:

• القوة = the power/strength
• مهمة = important

Together: Power/strength is important.

This is called a nominal sentence. In the present tense, Arabic usually does not use a separate word for is.

Compare:

• القوة مهمة = Power is important
• كانت القوة مهمة = Power was important

This is very common in Arabic. Arabic often uses الـ with abstract ideas or generic concepts.

So القوة can mean:

• strength in a general sense
• power as a concept

In English, we often leave out the in these cases, but Arabic often keeps it.

So القوة مهمة is a perfectly normal way to say a general statement like Strength is important or Power is important.

Because here مهمة is the predicate of the sentence, not part of a noun phrase.

• القوة مهمة = Power is important
• القوة المهمة = the important power/strength

That is a very important difference.

If both words are definite, they usually make one noun phrase:

• القوة المهمة = the important strength/power

But in القوة مهمة, the second word is describing the first as the statement of the sentence:

• Power is important

Because قوة is a feminine noun, and adjectives in Arabic must agree with the nouns they describe.

So:

• قوة is feminine
• therefore مهمة must also be feminine

This is true even though the meaning is something abstract. In Arabic, grammatical gender is a grammar feature, not always a reflection of real-world sex.

Also, the ending ة is often a sign that a noun or adjective is feminine.

The written form القوة مهمة is very close to Standard Arabic, but it is also easy for Levantine speakers to use and understand.

The main difference is usually in pronunciation, not in the spelling:

• Standard Arabic pronunciation: al-quwwa muhimma
• Levantine-style pronunciation: il-ʔuwwa mhimme or el-quwwa mhimme

So the sentence is fine, but in everyday Levantine speech it will usually sound more colloquial than it looks on the page.

Because there is a shadda on the و, so the word is pronounced with a doubled consonant sound:

• not quwa
• but quw-wa

That is why learners often write or hear it as quwwa.

So قوة is pronounced roughly:

• quwwa in careful/standard pronunciation
• ʔuwwa for many Levantine speakers

Because Arabic normally puts the subject first and the predicate after it in this kind of sentence.

So:

• القوة = the topic/subject
• مهمة = what is being said about it

Also, in Arabic, adjectives usually come after the noun they describe.

In this sentence, مهمة is specifically a predicate adjective, so its position after القوة is exactly what you should expect.

Not if you want the same meaning.

• القوة مهمة = Power is important
• مهمة القوة does not normally mean the same thing

For a beginner, the safe pattern is:

• noun + adjective/predicate

So keep:

• القوة مهمة

If you change the order, you may create a different structure or something that sounds unnatural in ordinary speech.

It can mean any of those, depending on context.

Common possibilities include:

• strength = physical or inner strength
• power = authority or influence
• force = force in a more abstract or political sense

In a short sentence like القوة مهمة, the exact nuance depends on the larger context. Arabic often allows this kind of broad meaning when a word is used on its own.
