זה לא נשמע לי סביר לשלם שוב על אותו מסמך.

Here זה works like English it in sentences such as It doesn’t sound reasonable.

So:

• זה לא נשמע לי סביר = It doesn’t sound reasonable to me

It does not have to point to a physical object. It can refer to the whole idea that comes after it: paying again for the same document.

Hebrew often uses זה this way when introducing a judgment about an action or situation.

Yes, נשמע comes from the root ש־מ־ע and literally relates to hearing or sounding.

In this sentence, though, זה לא נשמע לי סביר means:

• That doesn’t sound reasonable to me
• or more naturally in English, That doesn’t seem reasonable to me

So נשמע is often used idiomatically, just like English sounds in:

• That sounds wrong
• That sounds expensive
• That doesn’t sound fair

It is not about an actual physical sound here. It is about someone’s impression of an idea.

Because the subject is זה, which is treated as masculine singular.

So the verb agrees with זה:

• זה נשמע = masculine singular
• זאת נשמעת = feminine singular

Even though the real idea is the whole action לשלם שוב על אותו מסמך, Hebrew commonly uses masculine singular זה as a default introducer.

לי literally means to me.

In this sentence:

• זה לא נשמע לי סביר = It doesn’t sound reasonable to me

This לי marks the person whose opinion or impression is being expressed.

Very common pattern:

• נראה לי = it seems to me
• נשמע לי = it sounds to me
• ברור לי = it’s clear to me

So לי is not an object like me in he heard me. It is more like to me / in my view.

סביר means reasonable.

So:

• לא נשמע לי סביר = doesn’t sound reasonable to me

It is a very common adjective in modern Hebrew. Depending on context, it can mean:

• reasonable
• plausible
• acceptable
• fair

Here reasonable is the best match.

Also, סביר is masculine singular, matching the default masculine singular structure with זה.

This is an infinitive phrase, and it gives the content of what is being judged.

Breakdown:

• לשלם = to pay
• שוב = again
• על אותו מסמך = for the same document

So the sentence structure is roughly:

• It doesn’t sound reasonable to me
  • to pay again for the same document

In smoother English:

• It doesn’t seem reasonable to me to pay again for the same document.

Hebrew often uses an infinitive like this after expressions such as:

• זה טוב... = It’s good to...
• זה קשה... = It’s hard to...
• זה לא הגיוני... = It’s not logical to...

Because שוב means again, and placing it after the infinitive is very natural Hebrew word order.

So:

• לשלם שוב = to pay again

This is the most straightforward placement.

Hebrew adverbs like שוב often come right after the verb or infinitive they modify.

Good question. In Hebrew, לשלם can combine with different kinds of complements:

• לשלם על משהו = to pay for something
• לשלם למישהו = to pay someone
• לשלם סכום = to pay an amount

So here:

• לשלם על אותו מסמך = to pay for that same document

The preposition על is the normal one for pay for when talking about the thing you are paying for.

Examples:

• שילמתי על הכרטיס. = I paid for the ticket.
• שילמתי למורה. = I paid the teacher.
• שילמתי מאה שקלים. = I paid one hundred shekels.

Yes, אותו can mean him as a direct object pronoun, but here it means the same.

In this sentence:

• אותו מסמך = the same document

This is a very common Hebrew pattern:

• אותו יום = the same day
• אותה בעיה = the same problem
• אותם אנשים = the same people

So here אותו agrees with מסמך, which is masculine singular.

This is different from pronoun use like:

• ראיתי אותו = I saw him

The noun after it makes the meaning clear.

Because אותו already behaves like a definite expression in this structure.

So Hebrew says:

• אותו מסמך = the same document

You do not normally say האותו מסמך.

This is similar to other Hebrew words that already make the noun definite in meaning.

Yes. That is also correct and natural.

Compare:

• זה לא נשמע לי סביר לשלם שוב על אותו מסמך
• לשלם שוב על אותו מסמך לא נשמע לי סביר

Both mean essentially the same thing.

The difference is mostly one of style and focus:

• זה לא נשמע לי סביר... starts with a general judgment: It doesn’t sound reasonable...
• לשלם שוב על אותו מסמך... puts the action itself first: Paying again for the same document...

Both are common in Hebrew.

It is not completely fixed, but it is a very common natural pattern.

Hebrew speakers often say things like:

• זה נשמע לי טוב = That sounds good to me
• זה לא נשמע לי נכון = That doesn’t sound right to me
• זה לא נשמע לי הגיוני = That doesn’t sound logical to me
• זה לא נשמע לי סביר = That doesn’t sound reasonable to me

So the frame זה נשמע לי + adjective is very useful and productive.

Yes, in many contexts it would.

• זה לא נראה לי סביר = It doesn’t seem reasonable to me
• זה לא נשמע לי סביר = It doesn’t sound reasonable to me

The difference is subtle:

• נשמע לי is closer to sounds to me, often reacting to an idea, proposal, explanation, or wording.
• נראה לי is closer to seems to me, a bit broader and sometimes more neutral.

In this sentence, both are possible, but נשמע לי סביר is very natural.

It is mostly neutral natural Hebrew.

It sounds perfectly normal in speech and writing. It is not slang, and it is not especially formal either.

You could use it in:

• everyday conversation
• customer-service situations
• workplace discussion
• written complaint or email

For example, if someone is asked to pay twice for the same paperwork, this sentence would sound very natural.

Yes — several very useful ones:

• נשמע לי = sounds to me / seems to me
• סביר = reasonable
• לשלם על = to pay for
• שוב = again
• אותו / אותה / אותם / אותן
  • noun = the same ...
• מסמך = document

These are all high-value words and patterns for real-life Hebrew.
