לפני שאני שולחת את הבקשה, אני רוצה לבדוק שכל הפרטים נכונים.

Because שולחת is the feminine singular form, used when the speaker is female.

• אני שולחת = I send / I am sending / I will send
• אני שולח = I send / I am sending / I will send, said by a male speaker

So if a man were saying this sentence, it would be:

לפני שאני שולח את הבקשה, אני רוצה לבדוק שכל הפרטים נכונים.

Hebrew often uses the present-tense participle after לפני ש... to talk about something that is about to happen or expected to happen.

So:

• לפני שאני שולחת את הבקשה = before I send the request

This is very natural in everyday Hebrew.

You could also say:

• לפני שאשלח את הבקשה...

That version is also correct, but it sounds a bit more formal or written. In normal speech, לפני שאני שולחת is extremely common.

שאני is made of two parts:

• ש = that / which / when, depending on context
• אני = I

Here, after לפני, it gives the meaning before I...

So:

• לפני ש... = before...
• לפני שאני שולחת = before I send / before I am sending

It is not a special separate word in meaning; it is basically ש + אני written together.

In Hebrew, את marks a definite direct object.

Here:

• בודקת / שולחת מה? → את הבקשה
• הבקשה = the request / application

Because the object is definite, Hebrew uses את:

• אני שולחת את הבקשה = I am sending the request

But if it were indefinite, you would usually leave out את:

• אני שולחת בקשה = I am sending a request

So את does not mean the. It is just a grammatical marker used before a definite direct object.

It can mean either one, depending on context.

• בקשה = request
• In many real-life situations, it can also mean an application, especially a formal one

So in this sentence, הבקשה could be:

• the request
• the application

The surrounding context tells you which one is intended.

After רוצה in Hebrew, you usually use an infinitive, just like English want to check.

• אני רוצה = I want
• לבדוק = to check

So:

• אני רוצה לבדוק = I want to check

This is a very common structure:

• אני רוצה ללכת = I want to go
• אני רוצה לראות = I want to see
• אני רוצה לשאול = I want to ask

לבדוק is a broad verb that can mean:

• to check
• to examine
• to inspect
• to verify

In this sentence, to check or to make sure is the best fit:

• אני רוצה לבדוק שכל הפרטים נכונים = I want to check that all the details are correct

So the feeling is: review the information and make sure everything is right.

Yes, it is written as one word here, but it is really:

• ש = that
• כל = all

So:

• שכל הפרטים נכונים = that all the details are correct

This ש is very common in Hebrew and often introduces a clause:

• אני יודע ש... = I know that...
• אני חושב ש... = I think that...
• אני רוצה לבדוק ש... = I want to check that...

הפרטים means the details.

In this sentence, the speaker is referring to a specific set of details, namely the details in the request/application. That is why Hebrew uses the definite article ה־.

• פרטים = details
• הפרטים = the details

Both are possible in Hebrew depending on context, but שכל הפרטים נכונים sounds natural when referring to all the relevant details already understood from the situation.

Because it agrees with הפרטים, which is masculine plural.

• פרט = detail
• פרטים = details

So the adjective must also be masculine plural:

• נכון = correct, masculine singular
• נכונה = correct, feminine singular
• נכונים = correct, masculine plural
• נכונות = correct, feminine plural

Since הפרטים is masculine plural, Hebrew uses נכונים.

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

So:

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

This is normal Hebrew grammar.

Compare:

• אני עייף = I am tired
• היא בבית = she is at home
• הספר מעניין = the book is interesting

No present-tense is/are is needed.

Usually, no—not naturally in this exact structure.

The sentence has two separate clauses:

• לפני שאני שולחת את הבקשה
• אני רוצה לבדוק...

In the second clause, Hebrew normally includes אני:

• אני רוצה לבדוק

You might hear subject pronouns omitted in some contexts, but with רוצה in everyday standard Hebrew, saying אני here is very natural and expected.

The comma is natural and standard here because the sentence begins with a subordinate clause:

• לפני שאני שולחת את הבקשה, ...

Then comes the main clause:

• אני רוצה לבדוק...

So the comma helps separate:

• Before I send the request,
• I want to check...

In casual texting, people may leave punctuation out, but in correct written Hebrew, the comma is appropriate.

Only the gendered forms need to change.

Female speaker:

• לפני שאני שולחת את הבקשה, אני רוצה לבדוק שכל הפרטים נכונים.

Male speaker:

• לפני שאני שולח את הבקשה, אני רוצה לבדוק שכל הפרטים נכונים.

Notice that רוצה stays the same in spelling for both masculine and feminine singular in the present tense, but it is pronounced differently in careful speech by some speakers:

• masculine: ro-tse
• feminine: ro-tsa

In everyday writing, both are written רוצה.

Yes. נכון / נכונים can mean:

• correct
• right
• accurate

So שכל הפרטים נכונים can be understood as:

• that all the details are correct
• that all the details are accurate
• that everything in the details is right

The exact English wording depends on context, but the Hebrew is very natural for checking information before submitting something.
