لن أشارك رمز التحقق أبدا.

لن is the standard MSA particle for negating a future action. Here it means will not.

So:

لن أشارك = I will not share

By contrast, لا أشارك usually means I do not share or I am not sharing. In some contexts it can sound future-ish, but لن is the clearer and more standard choice for will not.

A grammar note: لن puts the following present-tense verb into the subjunctive/manṣūb form. In fully vocalized Arabic, أُشارِكُ becomes أُشارِكَ after لن. In normal unvocalized writing, both look like أشارك.

Because Arabic verbs already show the subject.

In أشارك, the prefix أ- tells you the subject is I. So Arabic usually does not need an extra أنا.

That means:

أشارك = I share / I will share
لن أشارك = I will not share

You could say أنا لن أشارك if you want extra emphasis, like I myself will not share or as for me, I will not share.

Yes. أشارك is from the verb شارك.

In Modern Standard Arabic, شارك can mean:

• to share
• to participate, depending on context

Here, because it takes رمز التحقق as its object, the meaning is clearly share:

أشارك رمز التحقق = share the verification code

A useful comparison:

• شارك شيئًا = share something
• اشترك usually means participate, subscribe, or sign up, not share something

So in this sentence, أشارك is the natural choice.

Because رمز التحقق is an iḍāfa construction, often called a construct phrase.

Literally, it is:

رمز = code
التحقق = the verification

So the whole phrase is literally code of the verification, which English naturally renders as the verification code.

In an iḍāfa:

• the first noun usually does not take ال
• the whole phrase can still be definite if the second noun is definite

So رمز التحقق is definite as a whole, even though رمز by itself has no ال.

التحقق means verification, checking, or confirmation, depending on context.

In tech/security language, رمز التحقق is the normal expression for:

• verification code
• sometimes confirmation code
• sometimes a one-time code used to prove your identity

So the phrase is very standard modern Arabic.

Yes, لن already makes the sentence negative:

لن أشارك رمز التحقق = I will not share the verification code

Adding أبدًا strengthens that idea. After a negative, أبدًا means something like:

• ever
• at all
• and in natural English, often never

So:

لن أشارك رمز التحقق أبدًا = I will never share the verification code

It adds emphasis, not a completely new meaning.

A fully vocalized version is:

لَن أُشارِكَ رَمزَ التحقُّقِ أبدًا.

Word by word:

• لَن
• أُشارِكَ
• رَمزَ
• التحقُّقِ
• أبدًا

Those endings show the grammar more clearly:

• أُشارِكَ: subjunctive after لن
• رَمزَ: direct object, so accusative
• التحقُّقِ: second part of the iḍāfa, so genitive
• أبدًا: adverbial accusative

Not exactly. In التحقق, the ل of ال is assimilated because ت is a sun letter.

So التحقق is pronounced roughly:

at-taḥaqquq

not al-taḥaqquq

In the full sentence, a rough pronunciation is:

lan u-shaa-ri-ka ramza t-ta-haq-qu-qi abadan

If you want a more natural connected pronunciation, the beginning of the noun phrase sounds like:

ramza t-taḥaqquqi

because the helping vowel of الـ drops in connected speech.

Here is the basic breakdown:

لن
A particle meaning will not; it negates the future and makes the following imperfect verb subjunctive.

أشارك
An imperfect verb meaning I share; after لن, it means I will not share.

رمز
The direct object: the thing being shared.

التحقق
The second noun in an iḍāfa phrase; it specifies what kind of code it is: verification code.

أبدًا
An adverb meaning ever / at all / never in negative contexts; it emphasizes the negation.

So structurally, the sentence is:

[future negation] + [verb] + [object phrase] + [emphatic adverb]
