بريد الاسترداد الموثوق في الحساب.

Usually no. It is most naturally a noun phrase or UI label, not a complete sentence.

Arabic interface text often uses short labels like this, just as English does with things like Recovery email or Trusted recovery email in the account. There is no verb here.

Arabic often expresses of by putting two nouns together in an iḍāfa construction.

So:

• بريد = mail / email
• الاسترداد = recovery

Together, بريد الاسترداد literally means mail of recovery, which English naturally turns into recovery email.

So the of is understood from the structure; Arabic does not need a separate word here.

Because in an iḍāfa construction, the first noun normally does not take الـ.

So you get:

• بريد الاسترداد
  not
• البريد الاسترداد

Even without الـ on بريد, the whole phrase can still be definite because the second noun, الاسترداد, is definite.

This is a very common Arabic pattern:

• باب البيت = the door of the house / the house’s door
• بريد الاسترداد = the recovery email

Because adjectives normally come after the nouns they describe in Arabic.

So:

• بريد الاسترداد = recovery email
• بريد الاسترداد الموثوق = the trusted recovery email

The adjective comes after the whole iḍāfa phrase, not in the middle of it.

Because the adjective agrees with the whole noun phrase, not just the visible form of the first word.

Even though بريد has no الـ, بريد الاسترداد as a whole is definite. So the adjective must also be definite:

• بريد الاسترداد الموثوق

This is normal adjective agreement in Arabic. The adjective matches what it describes in:

• definiteness
• gender
• number
• case (in fully vowelled Arabic)

In normal understanding, it describes the email—so the meaning is the trusted/verified recovery email.

Technically, because both بريد and الاسترداد are masculine singular, the form by itself does not completely remove all ambiguity. But in real context, especially in account or settings language, readers will understand that the adjective refers to the email/recovery-email item, not to recovery as an abstract noun.

في الحساب literally means in the account.

In natural English, depending on context, you might translate it as:

• in the account
• on the account
• associated with the account

It is a prepositional phrase:

• في = in
• الحساب = the account

This phrase tells you where the recovery email belongs or is registered.

Yes. After a preposition like في, the following noun is in the genitive case.

So الحساب here is grammatically majrūr (genitive). In normal unvowelled Arabic writing, you usually do not see the case ending, but in fully vowelled Arabic it would be:

• في الحسابِ

This is a standard rule:

• في البيتِ = in the house
• في الحسابِ = in the account

By itself, بريد basically means mail/post. But in modern tech context, it is often understood as email, especially in short interface text.

A fuller expression could be:

• البريد الإلكتروني للاسترداد = the recovery email / recovery email address

So بريد الاسترداد is a shorter label-like way of expressing that idea.

A normal pause-form pronunciation would be:

barīd al-istirdād al-mawthūq fī al-ḥisāb

If you added full case endings in a nominative context, it could be:

barīdu al-istirdādi al-mawthūqu fī al-ḥisābi

In everyday reading and in UI text, learners usually read it in the simpler pause form without worrying about final case vowels.

Not always exactly.

• موثوق usually means trusted, reliable, or trustworthy
• موثَّق often means verified, authenticated, or documented

So in some technical contexts, a native speaker might expect موثَّق if the intended meaning is specifically verified. But if the idea is trusted recovery email, then موثوق fits well.

So this is a useful nuance to know, even if the intended meaning has already been provided to you.
