בשלב השני של התהליך צריך לבדוק שכל הפרטים נכונים.

בשלב means at the stage or in the stage.

It is made of:

• ב־ = in / at
• שלב = stage

So בשלב השני literally means at the second stage.

Hebrew often attaches short prepositions like ב־, ל־, and כ־ directly to the following word.

In Hebrew, adjectives usually come after the noun.

So:

• שלב שני = a second stage
• השלב השני = the second stage

The adjective שני comes after שלב, and if the noun is definite, the adjective must also be definite. That is why both words take ה־ in the full phrase השלב השני.

In your sentence, the noun appears inside בשלב השני, where the ה on שלב is absorbed after the preposition ב־, but the phrase is still definite: in the second stage.

של התהליך means of the process.

Hebrew has two common ways to express of:

1. Construct state (smikhut), like שלב התהליך
2. X של Y, like שלב של התהליך

In this sentence, של התהליך is a very natural and clear way to say of the process.

So:

• בשלב השני של התהליך = in the second stage of the process

A construct version is sometimes possible in similar phrases, but של is extremely common and often easier for learners to recognize.

Here צריך means it is necessary / one needs to.

In this sentence, it is being used impersonally. That means Hebrew does not explicitly say who must do it. English often uses:

• you need to
• one needs to
• it is necessary to

So צריך לבדוק here is best understood as:

• it is necessary to check
• you need to check
• one should check

Even though צריך is singular masculine in form, in this kind of impersonal sentence it often works like a general need to / must.

לבדוק is the infinitive form, meaning to check.

Hebrew often uses this pattern:

• צריך + infinitive
• literally: need + to do something

So:

• צריך לבדוק = need to check

The ל־ at the beginning of לבדוק is the normal marker used in Hebrew infinitives, similar to English to in to check.

שכל here means that all.

It is made of:

• ש־ = that
• כל = all / every

So:

• שכל הפרטים נכונים = that all the details are correct

This introduces the content of what must be checked.

You can think of the sentence structure like this:

• צריך לבדוק = it is necessary to check
• שכל הפרטים נכונים = that all the details are correct

הפרטים means the details.

Hebrew often uses the definite article where English might or might not. In this sentence, the speaker means a specific set of details related to the process, so the details is natural.

• פרטים = details
• הפרטים = the details

Since the sentence is about checking a known set of details, the definite form makes sense.

Because it agrees with הפרטים, which is plural masculine.

• פרט = detail (singular)
• פרטים = details (plural)

So the adjective also has to be plural masculine:

• נכון = correct (masculine singular)
• נכונים = correct (masculine plural)

Therefore:

• הפרטים נכונים = the details are correct

Hebrew usually does not use a separate word for am / is / are in the present tense.

So:

• הפרטים נכונים literally looks like the details correct
• but it means the details are correct

This is a very common feature of Hebrew. In the present tense, the linking verb is usually omitted.

The sentence begins with a time/stage phrase, then gives the main action, then the content being checked:

• בשלב השני של התהליך = in the second stage of the process
• צריך לבדוק = it is necessary to check
• שכל הפרטים נכונים = that all the details are correct

So the full structure is:

[At the second stage of the process] + [need to check] + [that all the details are correct]

This is a very normal Hebrew sentence pattern.

Yes. That is a very natural English translation.

The Hebrew verb לבדוק literally means to check, but depending on context, English may translate it as:

• check
• verify
• make sure

So this sentence can be understood as:

• In the second stage of the process, you need to check that all the details are correct.
• In the second stage of the process, you should make sure all the details are correct.

Both are good ways to express the idea.
