رمز التحقق آمن.

A careful MSA reading is:

ramzu t-taḥaqquqi ʾāminun

In ordinary, unvowelled reading, learners often say it more simply as:

ramz at-taḥaqquq āmin

A few pronunciation notes:

• ر = rolled/flapped r
• ح = a strong h from the throat
• ق = q, pronounced farther back than English k
• In التحقق, the ل of ال is not pronounced clearly because ت is a sun letter, so التحقق sounds like at-taḥaqquq

Because this is a nominal sentence in Arabic. In the present tense, Arabic usually does not use a separate word for is/are.

So:

• رمز التحقق آمن = The verification code is secure

The idea of is is understood automatically.

If you wanted the past or future, Arabic would express that differently.

Because رمز التحقق is an iḍāfa construction, often called a genitive/possessive construction.

In an iḍāfa:

• the first noun usually does not take الـ
• the second noun can carry the definiteness

So:

• رمز التحقق = literally code of the verification
• naturally: the verification code

Even without الـ on رمز, the whole phrase can still be definite because of the iḍāfa structure.

It is an iḍāfa construction: noun + noun.

Here:

• رمز = code
• التحقق = verification

Together they mean:

• code of verification
• more naturally in English: verification code

This structure is extremely common in Arabic, and English often translates it with of or by turning it into a compound noun.

No. التحقق is not an adjective here.

It is a noun—more specifically, a verbal noun (maṣdar) meaning something like verification or checking.

So the structure is not:

• code + verifying

It is:

• code + verification

That is why this is an iḍāfa phrase, not a noun + adjective phrase.

In an iḍāfa construction, the second noun is in the genitive case.

So in full vowelled form:

• رَمْزُ = nominative
• التَّحَقُّقِ = genitive
• آمِنٌ = nominative

Full form:

رَمْزُ التَّحَقُّقِ آمِنٌ

In normal modern writing, these case endings are usually not written, but they are still understood in formal grammar.

Because آمن is the predicate of the sentence.

The sentence has:

• subject/topic: رمز التحقق
• predicate/comment: آمن

So the order is:

• The verification code
  • secure

This is the normal pattern for a basic Arabic nominal sentence.

Also, آمن here is not an adjective inside the noun phrase; it is a predicate adjective, meaning it tells you something about the subject.

Because it agrees with the head noun رمز, which is:

• masculine
• singular

Even though رمز التحقق has two words, the head of the phrase is رمز, so the predicate matches that.

That is why you get:

• آمن and not آمنة

If the main noun were feminine, the predicate would usually be feminine too.

Here it is functioning as an adjective meaning secure/safe.

That matters because the written form آمن can also look like a verb in other contexts. But in this sentence, the structure clearly shows it is an adjective/predicate:

• رمز التحقق = subject
• آمن = predicate adjective

So this sentence is not saying someone believed or trusted; it is describing the code as secure.

It would be:

رَمْزُ التَّحَقُّقِ آمِنٌ

Breakdown:

• رَمْزُ = ramzu — nominative, because it is the subject
• التَّحَقُّقِ = at-taḥaqquqi — genitive, because it is the second term of the iḍāfa
• آمِنٌ = ʾāminun — nominative predicate

In everyday Arabic writing, these short vowels and case endings are usually omitted:
