לפני שנחתום, אני רוצה לוודא שאין משהו מוזר בהסכם.

Because Hebrew commonly uses לפני ש־ + future for something that has not happened yet.

So:

• לפני = before
• שנחתום = we sign / we will sign

Together, לפני שנחתום means before we sign.

נחתום is the 1st person plural future form of לחתום (to sign).

Breakdown:

• לחתום = to sign
• נחתום = we will sign

The root is ח-ת-מ.

The prefix ש־ is a very common Hebrew connector meaning something like that, which, or sometimes just marking a subordinate clause.

In this sentence:

• שנחתום = that we sign / when we sign → after לפני, it gives before we sign
• שאין = that there is not / that there isn't

So ש־ helps introduce the dependent clause after לפני and after לוודא.

לוודא means to make sure, to verify, or to confirm.

So:

• אני רוצה לוודא = I want to make sure

It is a very natural word here, especially in a context like checking a document or contract.

This is a modern Hebrew spelling convention. A consonant v sound is often written with double ו.

So לוודא helps signal the pronunciation more clearly.

It is pronounced roughly levade.

Because אין and לא do different jobs.

• לא negates verbs: I do not want, we will not sign
• אין means there is no / there isn't / there are not

Here the sentence is saying that no strange thing exists in the agreement, so אין is the right choice:

• שאין משהו מוזר = that there isn't anything strange

שאין is just:

• ש־ = that
• אין = there is not / there isn't

So שאין means that there isn't or that there aren't.

Hebrew often attaches little words like ש־ directly to the next word.

Literally, משהו means something.

But in a negative sentence, English often prefers anything, so:

• אין משהו מוזר = there isn't anything strange

A slightly more explicit Hebrew version would be:

• אין שום דבר מוזר = there isn't anything strange / there is nothing strange

So the sentence is natural, especially in everyday speech.

Because it matches משהו, which is treated as masculine singular.

So:

• משהו מוזר = something strange

If the noun were feminine, the adjective would usually change to the feminine form.

Without vowel marks, בהסכם can be ambiguous in writing.

It can represent:

• beheskem = in an agreement
• baheskem = in the agreement

Only context tells you which one is meant. In this sentence, the meaning is in the agreement.

Not from the spelling alone.

In unpointed Hebrew, רוצה can be read as:

• rotze = masculine
• rotza = feminine

So אני רוצה could mean I want said by either a man or a woman. In speech, you hear the difference.

You can move it.

Both are natural:

• לפני שנחתום, אני רוצה לוודא שאין משהו מוזר בהסכם.
• אני רוצה לוודא לפני שנחתום שאין משהו מוזר בהסכם.

Starting with לפני שנחתום puts a little more focus on the timing: before we sign...

A useful transliteration is:

lifnei she-nakhtom, ani rotze/rotza levade she-ein mashehu muzar baheskem

Notes:

• rotze if the speaker is male
• rotza if the speaker is female
• baheskem here matches the meaning in the agreement

The strongest stresses are roughly:

lifNEI she-nakhTOM, aNI rotZE/rotZA levaDE she-EIN maSHEhu muZAR ba-hesKEM
