אם משהו לא ברור לך בעמוד הראשון, תשאלי אותי לפני שאת שולחת את הטופס.

Because the sentence is addressed to one female person.

• תשאלי = ask! said to a woman
• שולחת = sending in feminine singular
• שאת שולחת = that you are sending / when you send, with you referring to a woman

If you were speaking to a man, you would say:

• תשאל אותי
• לפני שאתה שולח את הטופס

Because Hebrew expresses this idea as something is not clear to you, not something does not clear you.

So:

• ברור = clear
• לא ברור לך = not clear to you

The word לך is an indirect object meaning to you.

This is a very common Hebrew pattern:

• זה ברור לי = This is clear to me
• זה לא ברור להם = This is not clear to them

Using אותך here would be ungrammatical.

Here אם means if.

So:

• אם משהו לא ברור לך... = If something is not clear to you...

This is the normal Hebrew way to start a conditional sentence.

Compare:

• אם יש לך שאלה, תשאלי = If you have a question, ask
• אם את צריכה עזרה, תגידי לי = If you need help, tell me

Both are possible, but לא ברור is much more natural in everyday spoken and written Hebrew.

• לא ברור = common, neutral, everyday
• אינו ברור = more formal or literary

So in ordinary speech or normal instructions, משהו לא ברור לך is exactly what you would expect.

Literally, בעמוד הראשון means in/on the first page.

The prefix ב־ usually means in, at, or sometimes on, depending on the context.

Here:

• עמוד = page
• העמוד הראשון = the first page
• בעמוד הראשון = on the first page

Hebrew often uses ב־ where English would say on with pages, forms, lists, etc.

Because the noun is definite: the first page, not just a first page.

In Hebrew, adjectives agree with the noun in definiteness. So if the noun has ה־, the adjective usually does too.

• עמוד ראשון = a first page
• העמוד הראשון = the first page

Since the sentence has בעמוד הראשון, it means on the first page.

Because לשאול takes a direct object for the person being asked.

So:

• לשאול מישהו = to ask someone
• לשאול משהו = to ask something

That is why you get:

• תשאלי אותי = ask me

Not תשאלי לי.

Examples:

• שאלתי אותו שאלה = I asked him a question
• תשאלי את המורה = Ask the teacher

Here ש־ is a shortened form of אשר / ש..., often meaning that.

In this sentence, לפני שאת שולחת literally means before that you send, but in natural English we say before you send.

So:

• לפני = before
• שאת שולחת = you send / you are sending

This structure is very common after words like לפני, אחרי, כשה־, etc.

Examples:

• לפני שאתה הולך = before you go
• אחרי שהיא מגיעה = after she arrives
• כשהם מדברים = when they speak

Because in Hebrew, after words like לפני ש־ (before), אחרי ש־ (after), and כש־ (when), Hebrew often uses a present-tense form where English may use a present form too, even if the whole sentence refers to a future action.

So:

• לפני שאת שולחת את הטופס = before you send the form

This is normal Hebrew usage. It does not mean the sending is happening right now.

Usually no, not in this sentence.

When the subject is stated explicitly as you, Hebrew normally uses לפני ש־ + clause:

• לפני שאת שולחת את הטופס

Using an infinitive after לפני is possible in some situations, but it works differently and often sounds less natural here.

For example:

• לפני שליחת הטופס = before sending the form
  This is more formal and noun-based.
• לפני שתשלחי / לפני שאת שולחת את הטופס = the natural clause form with you

So the given sentence is the normal conversational choice.

In Hebrew, the future tense form is also used for many commands, especially in the second person.

So:

• תשאלי is grammatically a future form
• but in context it means ask!

This is completely standard Hebrew.

Compare:

• תכתבי לי = write to me
• תבואי מחר = come tomorrow
• תסגרי את הדלת = close the door

So learners often think, Why is this future? The answer is: in Hebrew, these forms commonly serve as imperatives.

Here are the main variants:

To one man:

• אם משהו לא ברור לך בעמוד הראשון, תשאל אותי לפני שאתה שולח את הטופס.

To several women:

• אם משהו לא ברור לכן בעמוד הראשון, תשאלו אותי לפני שאתן שולחות את הטופס.

To several men / a mixed group:

• אם משהו לא ברור לכם בעמוד הראשון, תשאלו אותי לפני שאתם שולחים את הטופס.

This is a good sentence for noticing how Hebrew changes for gender and number in both pronouns and verbs.

It is very normal Hebrew word order.

Breakdown:

• תשאלי אותי = ask me
• לפני שאת שולחת את הטופס = before you send the form

Hebrew often puts the direct object right after the verb:

• תשאלי אותי
• תשלחי את הטופס
• תקראי את ההוראות

So nothing unusual is happening here; this is standard, natural phrasing.

טופס means form.

With ה־, it becomes the form:

• טופס = a form
• הטופס = the form

So:

• את הטופס = the form as the direct object

The sentence refers to a specific form already known from context, which is why it uses the definite form.
