هل أنت متأكد؟

هل is a yes/no question particle. It turns the statement into a question, like are you sure?

A key point for English speakers: Arabic does not usually change word order the way English does.
So instead of moving a verb before the subject, Arabic often just adds هل at the beginning.

• Statement: أنت متأكد = You are sure
• Question: هل أنت متأكد؟ = Are you sure?

There is no separate word for are in this sentence.

In Arabic, the verb to be is usually not expressed in the present tense when linking a subject and an adjective or noun.

So:

• أنت متأكد literally looks like you sure
• but it means you are sure

This is very normal in Arabic. The meaning of are is understood automatically.

أنت means you (masculine singular).

It is needed because this is a nominal sentence in the present tense, with no written verb meaning are. So أنت is the subject of the sentence.

Structure:

• هل = question marker
• أنت = subject, you
• متأكد = predicate adjective, sure/certain

In casual spoken Arabic, people may sometimes drop pronouns in some contexts, but in standard Arabic, هل أنت متأكد؟ is the normal full form.

متأكد means sure or certain, and grammatically it is an active participle used like an adjective.

Its fully vocalized form is:

• مُتَأَكِّد

It comes from the verb تأكّد = to become sure / to make sure / to confirm oneself.

In this sentence, متأكد functions as the predicate: it describes the subject أنت.

So the whole sentence is literally something like:

• Are you [a sure/certain person]?
• more naturally: Are you sure?

It is masculine because أنت here is the masculine singular form of you.

Arabic adjectives must agree with the person they describe in gender and number.

So:

• to a man: هل أنتَ متأكد؟
• to a woman: هل أنتِ متأكدة؟

Notice both parts change:

• أنتَ = you (masculine singular)
• أنتِ = you (feminine singular)
• متأكد = sure (masculine)
• متأكدة = sure (feminine)

A common pronunciation is:

• hal anta muta'akkid?

More carefully, with full vowels:

• hal ʾanta mutaʾakkid?

A few pronunciation notes:

• هل = hal
• أنت = anta
• متأكد = muta'akkid

In متأكد, the ' represents a hamza sound, a small glottal stop.
Also, the k sound is actually doubled in careful pronunciation because the word is really مُتَأَكِّد with a shadda on ك.

That pause comes from the hamza in متأكد.

The word is not just a smooth string of sounds like mutakid. It is more like:

• mu-ta-ʾak-kid

The hamza creates a brief stop before the next vowel.
This is important in careful pronunciation, especially in Modern Standard Arabic.

So متأكد is better pronounced as muta'akkid than as mutakid.

In fully vocalized MSA, the sentence is:

• هَلْ أَنْتَ مُتَأَكِّدٌ؟

A few notes:

• هَلْ ends with sukūn
• أَنْتَ has its normal fixed form
• مُتَأَكِّدٌ takes -un because it is an indefinite predicate in the nominative

In everyday writing, these short vowels are usually not written, so you normally see:

• هل أنت متأكد؟

And in normal speech, speakers often do not pronounce every case ending fully.

The normal MSA order here is:

• هل أنت متأكد؟

That is the most natural and standard form.

Arabic does allow some flexibility in word order, but for a simple sentence like this, putting أنت before متأكد is the expected pattern.

So for learners, the safest model is:

• هل + subject + predicate

It is a perfectly normal Modern Standard Arabic sentence, and it is also widely understandable in speech.

In everyday dialects, people may say very similar things, sometimes without هل, for example:

• أنت متأكد؟
• إنت متأكد؟ in many spoken varieties

But if you are learning MSA, هل أنت متأكد؟ is an excellent standard version to learn.

You change both the pronoun and the adjective so they agree.

For a group of men or a mixed group:

• هل أنتم متأكدون؟

For a group of women:

• هل أنتن متأكدات؟

So the pattern is the same, but Arabic agreement changes the forms depending on who is being addressed.

Yes. A common alternative is واثق.

For example:

• هل أنت واثق؟

This can also mean Are you sure?, though واثق often leans more toward confident/certain.

Still, هل أنت متأكد؟ is one of the most common and direct ways to say Are you sure? in MSA.
