אם הבקשה דחופה, הכרחי לשלוח אותה עוד היום ולא לחכות למחר.

אם means if. It introduces a condition:

• אם הבקשה דחופה = If the request is urgent

This is very common in Hebrew, just like in English. The first part sets up the condition, and the second part gives the result or necessary action.

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

So:

• הבקשה דחופה literally looks like the request urgent
• but it means the request is urgent

This is normal Hebrew sentence structure. The same thing happens in many simple present-tense sentences:

• הילד עייף = The boy is tired
• הדלת פתוחה = The door is open

דחופה agrees with הבקשה, which is a feminine singular noun.

• בקשה = request (feminine)
• דחוף = urgent (masculine singular)
• דחופה = urgent (feminine singular)

So Hebrew adjectives must match the noun in gender and number.

Good question. Here הכרחי does not describe הבקשה. It is being used impersonally, meaning:

• הכרחי לשלוח אותה... = It is essential to send it...

So הכרחי here is not agreeing with בקשה. It functions more like an impersonal predicate: necessary / essential.

You can think of it as short for something like:

• זה הכרחי לשלוח אותה = It is essential to send it

In that kind of structure, masculine singular is the default form.

Both לשלוח and לחכות are infinitives:

• לשלוח = to send
• לחכות = to wait

After words like הכרחי (necessary / essential), Hebrew often uses an infinitive:

• הכרחי לעשות = It is necessary to do
• חשוב לזכור = It is important to remember
• אסור לעשן = It is forbidden to smoke

So הכרחי לשלוח אותה literally means It is essential to send it.

אותה means her / it (feminine singular direct object).

Here it refers back to הבקשה:

• הבקשה = the request
• לשלוח אותה = to send it

Because בקשה is feminine, the pronoun must also be feminine:

• masculine singular object: אותו
• feminine singular object: אותה

So Hebrew is showing grammatical agreement, even though in English we just say it.

עוד היום is a very useful expression. Here it means:

• still today
• before today is over
• later today, not tomorrow

So:

• לשלוח אותה עוד היום = to send it today, before the day ends

This can be confusing because עוד has several meanings in Hebrew, such as more, another, or still. In this sentence, the sense is roughly before it’s too late today / while it is still today.

Because לחכות usually takes the preposition ל־ before the thing or time you are waiting for.

So:

• לחכות למחר = to wait until tomorrow / to wait for tomorrow

Without ל־, it would sound wrong here.

Compare:

• אני מחכה לך = I’m waiting for you
• הוא מחכה לאוטובוס = He is waiting for the bus
• נחכה למחר = We’ll wait until tomorrow

Yes, literally it is to/for tomorrow, but in natural English translation it usually becomes:

• until tomorrow
• for tomorrow

In this sentence:

• לא לחכות למחר = not to wait until tomorrow

So the Hebrew uses ל־, but the most natural English wording is not always to tomorrow.

Hebrew often uses impersonal expressions where English might use a subject like you.

So instead of saying:

• אתה צריך לשלוח אותה = You need to send it

the sentence says:

• הכרחי לשלוח אותה = It is essential to send it

This sounds more formal and objective. It focuses on the necessity of the action, not on who specifically must do it.

Yes, usually הכרחי sounds more formal, stronger, and more objective.

Compare:

• צריך לשלוח אותה עוד היום = You need to send it today
• הכרחי לשלוח אותה עוד היום = It is essential to send it today

צריך is very common in everyday speech.
הכרחי sounds more formal, written, official, or emphatic.

In Hebrew, with an infinitive like לשלוח, the direct object normally comes after it:

• לשלוח אותה = to send it
• לקרוא את הספר = to read the book
• לקנות אותו = to buy it

That is the standard word order. For an English speaker, it may help to remember that Hebrew usually keeps the verb first in this kind of infinitive phrase.

The comma separates the if-clause from the main clause:

• אם הבקשה דחופה, ...
• If the request is urgent, ...

This is similar to English punctuation when a conditional clause comes first. It helps the sentence read more clearly.

Yes, לא לחכות עד מחר is also possible and may sound a little more explicitly like not wait until tomorrow.

Compare:

• לא לחכות למחר = not wait for/until tomorrow
• לא לחכות עד מחר = not wait until tomorrow

Both are understandable. The version in your sentence is natural and concise.

Yes, but normally that would sound less natural here.

In present-tense Hebrew, the word היא is usually unnecessary in a sentence like this:

• natural: אם הבקשה דחופה
• more marked/unusual here: אם הבקשה היא דחופה

Hebrew usually prefers the shorter form unless there is a special reason for emphasis, contrast, or style.

It breaks down like this:

• אם = if
• הבקשה דחופה = the request is urgent
• הכרחי = it is essential / necessary
• לשלוח אותה = to send it
• עוד היום = today, before the day ends
• ולא לחכות למחר = and not wait until tomorrow

So the structure is:

If + condition, it is essential + infinitive phrase

That pattern is very common in formal Hebrew.
